Streamr Network: Performance and Scalability Whitepaper

The Corea milestone of the Streamr Network went live in late 2019. Since then a few people in the team have been working on an academic whitepaper to describe its design principles, position it with respect to prior art, and prove certain properties it has. The paper is now ready, and it has been submitted to the IEEE Access journal for peer review. It is also now published on the new Papers section on the project website. In this blog, I’ll introduce the paper and explain its key results. All the figures presented in this post are from the paper.
The reasons for doing this research and writing this paper were simple: many prospective users of the Network, especially more serious ones such as enterprises, ask questions like ‘how does it scale?’, ‘why does it scale?’, ‘what is the latency in the network?’, and ‘how much bandwidth is consumed?’. While some answers could be provided before, the Network in its currently deployed form is still small-scale and can’t really show a track record of scalability for example, so there was clearly a need to produce some in-depth material about the structure of the Network and its performance at large, global scale. The paper answers these questions.
Another reason is that decentralized peer-to-peer networks have experienced a new renaissance due to the rise in blockchain networks. Peer-to-peer pub/sub networks were a hot research topic in the early 2000s, but not many real-world implementations were ever created. Today, most blockchain networks use methods from that era under the hood to disseminate block headers, transactions, and other events important for them to function. Other megatrends like IoT and social media are also creating demand for new kinds of scalable message transport layers.

The latency vs. bandwidth tradeoff

The current Streamr Network uses regular random graphs as stream topologies. ‘Regular’ here means that nodes connect to a fixed number of other nodes that publish or subscribe to the same stream, and ‘random’ means that those nodes are selected randomly.
Random connections can of course mean that absurd routes get formed occasionally, for example a data point might travel from Germany to France via the US. But random graphs have been studied extensively in the academic literature, and their properties are not nearly as bad as the above example sounds — such graphs are actually quite good! Data always takes multiple routes in the network, and only the fastest route counts. The less-than-optimal routes are there for redundancy, and redundancy is good, because it improves security and churn tolerance.
There is an important parameter called node degree, which is the fixed number of nodes to which each node in a topology connects. A higher node degree means more duplication and thus more bandwidth consumption for each node, but it also means that fast routes are more likely to form. It’s a tradeoff; better latency can be traded for worse bandwidth consumption. In the following section, we’ll go deeper into analyzing this relationship.

Network diameter scales logarithmically

One useful metric to estimate the behavior of latency is the network diameter, which is the number of hops on the shortest path between the most distant pair of nodes in the network (i.e. the “longest shortest path”. The below plot shows how the network diameter behaves depending on node degree and number of nodes.

Network diameter
We can see that the network diameter increases logarithmically (very slowly), and a higher node degree ‘flattens the curve’. This is a property of random regular graphs, and this is very good — growing from 10,000 nodes to 100,000 nodes only increases the diameter by a few hops! To analyse the effect of the node degree further, we can plot the maximum network diameter using various node degrees:
Network diameter in network of 100 000 nodes
We can see that there are diminishing returns for increasing the node degree. On the other hand, the penalty (number of duplicates, i.e. bandwidth consumption), increases linearly with node degree:

Number of duplicates received by the non-publisher nodes
In the Streamr Network, each stream forms its own separate overlay network and can even have a custom node degree. This allows the owner of the stream to configure their preferred latency/bandwidth balance (imagine such a slider control in the Streamr Core UI). However, finding a good default value is important. From this analysis, we can conclude that:
  • The logarithmic behavior of network diameter leads us to hope that latency might behave logarithmically too, but since the number of hops is not the same as latency (in milliseconds), the scalability needs to be confirmed in the real world (see next section).
  • A node degree of 4 yields good latency/bandwidth balance, and we have selected this as the default value in the Streamr Network. This value is also used in all the real-world experiments described in the next section.
It’s worth noting that in such a network, the bandwidth requirement for publishers is determined by the node degree and not the number of subscribers. With a node degree 4 and a million subscribers, the publisher only uploads 4 copies of a data point, and the million subscribing nodes share the work of distributing the message among themselves. In contrast, a centralized data broker would need to push out a million copies.

Latency scales logarithmically

To see if actual latency scales logarithmically in real-world conditions, we ran large numbers of nodes in 16 different Amazon AWS data centers around the world. We ran experiments with network sizes between 32 to 2048 nodes. Each node published messages to the network, and we measured how long it took for the other nodes to get the message. The experiment was repeated 10 times for each network size.
The below image displays one of the key results of the paper. It shows a CDF (cumulative distribution function) of the measured latencies across all experiments. The y-axis runs from 0 to 1, i.e. 0% to 100%.
CDF of message propagation delay
From this graph we can easily read things like: in a 32 nodes network (blue line), 50% of message deliveries happened within 150 ms globally, and all messages were delivered in around 250 ms. In the largest network of 2048 nodes (pink line), 99% of deliveries happened within 362 ms globally.
To put these results in context, PubNub, a centralized message brokering service, promises to deliver messages within 250 ms — and that’s a centralized service! Decentralization comes with unquestionable benefits (no vendor lock-in, no trust required, network effects, etc.), but if such protocols are inferior in terms of performance or cost, they won’t get adopted. It’s pretty safe to say that the Streamr Network is on par with centralized services even when it comes to latency, which is usually the Achilles’ heel of P2P networks (think of how slow blockchains are!). And the Network will only get better with time.
Then we tackled the big question: does the latency behave logarithmically?
Mean message propagation delay in Amazon experiments
Above, the thick line is the average latency for each network size. From the graph, we can see that the latency grows logarithmically as the network size increases, which means excellent scalability.
The shaded area shows the difference between the best and worst average latencies in each repeat. Here we can see the element of chance at play; due to the randomness in which nodes become neighbours, some topologies are faster than others. Given enough repeats, some near-optimal topologies can be found. The difference between average topologies and the best topologies gives us a glimpse of how much room for optimisation there is, i.e. with a smarter-than-random topology construction, how much improvement is possible (while still staying in the realm of regular graphs)? Out of the observed topologies, the difference between the average and the best observed topology is between 5–13%, so not that much. Other subclasses of graphs, such as irregular graphs, trees, and so on, can of course unlock more room for improvement, but they are different beasts and come with their own disadvantages too.
It’s also worth asking: how much worse is the measured latency compared to the fastest possible latency, i.e. that of a direct connection? While having direct connections between a publisher and subscribers is definitely not scalable, secure, or often even feasible due to firewalls, NATs and such, it’s still worth asking what the latency penalty of peer-to-peer is.

Relative delay penalty in Amazon experiments
As you can see, this plot has the same shape as the previous one, but the y-axis is different. Here, we are showing the relative delay penalty (RDP). It’s the latency in the peer-to-peer network (shown in the previous plot), divided by the latency of a direct connection measured with the ping tool. So a direct connection equals an RDP value of 1, and the measured RDP in the peer-to-peer network is roughly between 2 and 3 in the observed topologies. It increases logarithmically with network size, just like absolute latency.
Again, given that latency is the Achilles’ heel of decentralized systems, that’s not bad at all. It shows that such a network delivers acceptable performance for the vast majority of use cases, only excluding the most latency-sensitive ones, such as online gaming or arbitrage trading. For most other use cases, it doesn’t matter whether it takes 25 or 75 milliseconds to deliver a data point.

Latency is predictable

It’s useful for a messaging system to have consistent and predictable latency. Imagine for example a smart traffic system, where cars can alert each other about dangers on the road. It would be pretty bad if, even minutes after publishing it, some cars still haven’t received the warning. However, such delays easily occur in peer-to-peer networks. Everyone in the crypto space has seen first-hand how plenty of Bitcoin or Ethereum nodes lag even minutes behind the latest chain state.
So we wanted to see whether it would be possible to estimate the latencies in the peer-to-peer network if the topology and the latencies between connected pairs of nodes are known. We applied Dijkstra’s algorithm to compute estimates for average latencies from the input topology data, and compared the estimates to the actual measured average latencies:
Mean message propagation delay in Amazon experiments
We can see that, at least in these experiments, the estimates seemed to provide a lower bound for the actual values, and the average estimation error was 3.5%. The measured value is higher than the estimated one because the estimation only considers network delays, while in reality there is also a little bit of a processing delay at each node.

Conclusion

The research has shown that the Streamr Network can be expected to deliver messages in roughly 150–350 milliseconds worldwide, even at a large scale with thousands of nodes subscribing to a stream. This is on par with centralized message brokers today, showing that the decentralized and peer-to-peer approach is a viable alternative for all but the most latency-sensitive applications.
It’s thrilling to think that by accepting a latency only 2–3 times longer than the latency of an unscalable and insecure direct connecion, applications can interconnect over an open fabric with global scalability, no single point of failure, no vendor lock-in, and no need to trust anyone — all that becomes available out of the box.
In the real-time data space, there are plenty of other aspects to explore, which we didn’t cover in this paper. For example, we did not measure throughput characteristics of network topologies. Different streams are independent, so clearly there’s scalability in the number of streams, and heavy streams can be partitioned, allowing each stream to scale too. Throughput is mainly limited, therefore, by the hardware and network connection used by the network nodes involved in a topology. Measuring the maximum throughput would basically be measuring the hardware as well as the performance of our implemented code. While interesting, this is not a high priority research target at this point in time. And thanks to the redundancy in the network, individual slow nodes do not slow down the whole topology; the data will arrive via faster nodes instead.
Also out of scope for this paper is analysing the costs of running such a network, including the OPEX for publishers and node operators. This is a topic of ongoing research, which we’re currently doing as part of designing the token incentive mechanisms of the Streamr Network, due to be implemented in a later milestone.
I hope that this blog has provided some insight into the fascinating results the team uncovered during this research. For a more in-depth look at the context of this work, and more detail about the research, we invite you to read the full paper.
If you have an interest in network performance and scalability from a developer or enterprise perspective, we will be hosting a talk about this research in the coming weeks, so keep an eye out for more details on the Streamr social media channels. In the meantime, feedback and comments are welcome. Please add a comment to this Reddit thread or email [[email protected]](mailto:[email protected]).

Breaking down the aelf side-chain

Cloud computing, parallel processing, and AEDPoS have greatly improved the execution performance of any kind of smart contract, but when they are applied to enterprise-level scenarios, new problems crop up. To begin with, in software design, it is a rather bad idea to program all the methods in the same class. We always write a series of classes to inherit a base class, in order to decouple the functionalities and make the class extensible whenever needed. The same also applies to blockchain design. Second, since all the data and transactions are accessible to anyone through a blockchain explorer, if we put the smart contract and data of different enterprises or government sectors on a single blockchain, then everyone can see them, which means there will be no data privacy. Although there are encryption techniques which can mask data, such as zero knowledge proof, it is always better to put the data of different enterprises on different blockchains.
Based on these considerations, long before other projects even realized it, aelf proposed that side-chain technology should be applied to this scenario. Unfortunately, for someone who is new to blockchain, it is almost impossible to understand how side-chain works. Side-chain is not what it literally means, it is not subordinate to the main chain. On the contrary, a side chain is a blockchain distributed system with the same functions and nodes as a main chain (say, the aelf blockchain). As mentioned above, we can put the data of different enterprises on different blockchains. This means we can build many blockchains, and work magic (of course not magic in its literal sense) to make these chains connect to the aelf main chain (in fact, we can call any of these blockchains a main chain and the rest side chains). Currently, the most popular method of connecting any two blockchains, which we also call cross-chain, is using a middle-man. When we want to use bitcoin to play a decentralized game on Ethereum, we need to send a transaction with some amount of bitcoin to a locking bitcoin address, then the middle-man will exchange the locked BTC for ETH at a certain exchange rate and allocate to you the equivalent amount of ETH on Ethereum, which you can use for playing games.
But in aelf, we use a metadata indexing method, which is more straightforward. Unlike other projects who built on the blockchains of those already successful projects (such as Ethereum or the HyperLedger fabric framework for consortium blockchains), the aelf team has writen all the code and build the infrastructure from scratch. From the beginning, the aelf team has defined how the data structure of a blockchain, a block, a transaction etc. should look like in C#. In an aelf blockchain data structure, there is an attribute called blockchain ID, which is a unique hash; and in block data structure, there are several attributes called blockchain ID , Merkle tree root and related side chain block list. There is also one more important thing: all of aelf’s data structures are serialized and stored in Redis (a popular key-value pair database system), so is the side chain information. As a result, as the aelf main chain is growing with block production by BPs, other side chains can send transactions to cross-chain contracts, which then execute the related code to connect to the main chain’s network port and request the main chain to index the side chain block and pay the indexing fee.
The core issue here is how to index a side chain: when a main chain (the block data structure on the main chain, or the data records with main chain ID in Redis), receives a request from a side chain, it adds the side chain’s block head data structure to the related side chain block list, which means theoretically we have indexed or related a side chain. We have mentioned that there is also a blockchain ID in each block, this attribute allows a main chain to index blocks from different side chains. When a user on a main chain wants to access data on a side chain or vise versa, they just need to find the target block on the main chain and its related side chain block list, and then find the target block on the side chain via key indexing.
As we will explain later, blockchains for different application scenarios generate blocks at different speeds. Under such circumstances, a chain with slower speed might index many blocks from a chain that produces blocks faster. This method can be applied to scenarios such as forking.
In practice, we can build any number of blockchains, and relate it via indexing to the aelf main chain, with a specific category of smart contracts running on each of them. For example, we can allow only banking-related smart contracts deployed on a specific blockchain, and e-commerce smart contracts on another. Our whitepaper summarizes it best:
One chain, one contract.
Moreover, the indexing method can make many blockchains into a hierarchical tree structure, the root being the so-called main chain. That’s because a related blockchain can then again index another blockchain as its side chain, and the process can keep going on. Logically, this is in perfect accordance with hierarchical taxonomy, for example, the financial sector has many subcategories, such as banking, lending, investment and insurance, and under investment banking, there are venture capital, investment bank etc… Each subcategory is supported by an indexed blockchain.
So how do these blockchains collaborate in a distributed system? First we need to be know that any node in a distributed system is just a software instance running on your computer, or a process. In TCP/IP, a node is allocated a port number, so we can run any number of this type of instances on a computer. However, each instance has its own port number: we can run several blockchain nodes, one IPFS node, one bit-torrent node and etc. simultaneously. In aelf, you should first start a main chain instance, and then you can build and run a side chain instance. Transactions broadcast on the side chain are collected by the BP nodes (block production nodes) on the main chain. When smart contracts deployed on the side chain is triggered, the BP and full nodes on the main chain will run them.

Aelf — a blockchain based operating system

To perfect the design of our software system, aelf made the system extensible, flexible and pluggable. Just as there are thousands of Linux OS with only one Linux kernel. As Ethereum Founder Vitalik Buterin has explained, Ethereum can be seen as a world computer because there are lots of smart contracts running on it, and the contract execution results are consistent in all the distributed systems around the world. This idea is also embedded in aelf’s system and we call it a “blockchain infrastructure operating system”, or a distributed operating system.
Just like any OS, aelf has a kernel and a shell. In fact, aelf’s kernel is not something like a Linux kernel, it is just an analogy. There is a special concept in aelf’s kernel called the minimum viable blockchain system, which defines the most fundamental aspect of a blockchain. If a developer wants to create a new blockchain system or a new blockchain project, he does’t have to start from scratch, instead, he can directly extend and customize using the aelf blockchain open-source code. The technologies described above are all included in the minimum viable blockchain system. With these, anyone can customize:
  • Block property: block data structure, block packaging speed, transaction data structure, etc.
  • Consensus type: AEDPoS is used by default, but you can also use incentive consensus, like PoW and PoS. And you can also use the consensus of traditional distributed systems, like PoS and Practical Byzantine Fault Tolerance, or PBFT. In fact, the f evil nodes of 3f+1 nodes are the upper limit for any distributed system to reach a consensus, which is called the Byzantine Fault Tolerance, or BFT. In order to do this, there is a specific algorithm, but in 1999, a much more efficient algorithm to reach this consensus came along, that is the PBFT. In scenarios like private blockchain or consortium blockchain where there is no need for a incentive model, PBFT will be a good option.
  • Smart contract collection: In aelf, there are many predefined smart contracts that can be used directly by other contracts, such as token contract, cross-chain contract (also called CCTP, or cross chain transfer protocol), consensus contract, organization voting contracts, etc. Of course, you can also create your own contract with a brand new implementation logic.
  • Others.

Summary

So this is our breakdown of the aelf blockchain whitepaper. In previous articles, we first introduced two basic concepts which are often misinterpreted by other articles. After helping you get these two concepts straight, we then introduced aelf’s vast arsenal of powerful technology. If these articles helped you understand the aelf blockchain better, then I have reached my goal. But I must advise you to read the whitepaper for a more detailed explanation. With all this knowledge at your disposal, I believe you will be much more comfortable developing DApps on aelf.

The Network of Networks, Scalable Interoperability to Unleash the True Potential of Blockchain

The Network of Networks, Scalable Interoperability to Unleash the True Potential of Blockchain
There is not going to be one blockchain to rule them all, each have their own advantages and disadvantages. Interoperability is key to unlocking the true potential of blockchain, where it will have a profound effect across all industries, creating a secure, trusted and hyper-connected world.
The rise of The Networks of Networks, interconnecting all DLT Networks, existing off-chain networks and even the Internet itself. Where true, scalable interoperability can be achieved without requiring connected chains to fork their code and imposing limitations, without the overhead, bottleneck and single point of failure of adding another blockchain in the middle. Where it will be quick, easy and free to participate.
It’s time to stop the childish tribalism that’s plagued this space for so long and realise the bigger picture. Tribes fighting amongst themselves over a tiny insignificant island where there is a whole world out there to conquer if they work together. A rising tide lifts all boats and with the birth of The Network of Networks all connected projects can benefit from the efforts of each other, to usher in Mass adoption of Blockchain.

  9. Join your favourite Blockchain project to the Overledger Network Ecosystem

Overledger SDK Update

Quant have just released their Overledger SDK update which has enabled standardisation of objects to abstract and simplify how to interact with different types of blockchains (UXTO and Account-based) in a common model. As well as the ability to directly deploy, invoke and query smart contracts directly through Overledger. I strongly recommend reading the teams Overledger SDK Update which explains it in more detail and includes example use cases of how Overledger is being used and the benefits it brings. Dr Luke Riley also did a fantastic job providing an in-depth demo of the Overledger SDK Update via Video as well.
https://youtu.be/PbpaZpe4mTQ

“This update sets the foundations to build the ecosystem for Overleger Network, allowing stakeholders other than Quant to write any type (DLT and non-DLT) Overledger connectors and sets up the ecosystem with multiple entry points for Overledger Gateways. These updates open up the integration capabilities of Overledger to 3rd parties and create the foundations for the Overledger Network”

Standards

“Trusted standards mean that industry doesn’t need to reinvent the wheel, that innovations will be compatible and work with existing technology, and that products and services will be trusted too. Governments use standards as trusted solutions to complement regulation, and they give peace of mind to consumers who know they are not putting themselves or their families at risk.” — Acting ISO Secretary-General Kevin McKinley
The foundations need to align with internationally recognised standards as they play a crucial role in ensuring interoperability with new and existing technology and validates a product meets the best practices / regulation required to ensure Enterprises remains in compliance. CEO of Quant, Gilbert Verdian, founded the ISO TC 307 standard covering blockchain as a whole, which 56 countries are working towards today.
Countries involved with ISO TC 307 — https://www.iso.org/committee/6266604.html?view=participation
Gilbert Verdian is the chairman for the ISO TC 307 working group for interoperability of blockchain and distributed ledger technology systems as well as being chairman for Blockchain and Distributed Ledger Technology for BSI (British Standards Institution) which represent the UK and includes companies such as Quant, IBM, Microsoft, HSBC, BAE Systems, Huawei as well as a number of UK Government bodies such as BEIS — Department for Business, Energy & Industrial Strategy, Defence Science and Technology and the National Cyber Security Centre.
The standardisation updates to the Overledger SDK aligns with the work in ISO TC 307 and academic work from Dr Paolo Tasca and Dr Claudio Tessone to provide users with a clear distributed ledger data standard. This will enable everyone to easily create connectors in a standard way, facilitating interoperability with all of the connected blockchains / non-DLT networks that are already connected to Overledger through Overledger Gateways.

Security

Cybersecurity is in Quant’s DNA. The team have a rich heritage of working for Governments, banks and industry for over 20 years protecting organisations and people from security threats. Before Quant, Gilbert Verdian was the Chief Information Security Officer for Vocalink (Mastercard) where he was in charge of security for the entire payments infrastructure in the UK (£6 Trillion per year).
Gilbert has led a team determined to take security to another level, protecting a critical part of the UK’s infrastructure, protecting UK citizens and businesses from fraud and risk and, by extension, allowing them to live as they want to. Under Gilbert’s guidance, Vocalink security is not merely best-in-class, but setting a new standard. — https://connect.vocalink.com/2017/july/a-winning-streak/
In addition to Quant being selected as a Guarantor for Pay.UK, Gilbert has also been appointed to the Cybersecurity Advisory Board (Pay.UK is the UK’s leading retail payments authority and runs the UK’s retail payments operations, which includes Bacs, Faster Payments and Cheques.)
The pillars of security are Confidentiality, Integrity and Availability. As such, they have used their experience in running payment and financial infrastructure and critical national infrastructure for nations and embedded these principles into every aspect of Overledger.

Regulation

Regulation is playing an ever increasing role for blockchain. Standards and Security naturally complement and help define regulation. The verticals Quant are involved in with regards to regulation span the globe. Gilbert helped shape the conversation about consumer data protection rights during his time as CISO of NSW Health, and is continuing to serve as a cornerstone for policy within the adoption of blockchain in public infrastructure. Quant serves as a founding member of INATBA (The International Association of Trusted Blockchain Applications), which is the formal governing body of the European Blockchain Partnership, all of which is overseen in Brussels by the EU. More locally, Gilbert and team are in consistent contact with the House of Lords within the UK, and advises the FCA in matters regarding cryptoassets.

As recently seen in the SDK update, Overledger can serve as a key component of automatic compliance of governance bodies’ financial regulation, shown here by an Overledger instance reporting to the BoE’s Prudential Regulation Authority. Project BARAC, stewarded by University College London, is a project examining the impact Automatic Regulation as administered by Blockchain can have on the Federal Government. Most notably, the FCA and R3, the developers of Corda, are involved here. Gilbert’s recent engagements with the Federal Reserve Bank of Boston also seem to revolve around this very topic, with the Boston Fed pilot-testing a Supervisor Node for automatic regulatory compliance. While at P2PFISY 2019, it was noted by Gilbert that Raphael Auer’s “Regulation Automata” aligns very well with the vision of Overledger, with Paolo Tasca, former CSO of Quant, more recently co-hosting a recent blockchain panel with him. Raphael’s ideas will most likely be taken into consideration by the BIS, as they recently announced a trial of a 6 central banks collaboration centered around exploring CBDC, and are in the early stages of installing Innovation Hubs in Hong Kong, Switzerland, and Singapore.

Overledger Network

The Overledger Network is a network of networks, which allows enterprise and communities stakeholders to access and participate in a growing hyper-connected decentralised ecosystem. Enterprises, banks, central banks, trading venues, etc will be able to host their own secure dedicated gateways, enabling secure connectivity to permissioned networks, permissionless networks, ecosystems, consortia and other distributed technologies. Community members will also be able to run an Overledger gateway to further enhance the scalability, decentralisation and optimise network latency, providing enterprises, developers and users choice to use the closest gateway when accessing permissionless blockchains. The Overledger gateways will create a scalable p2p network that shares the transaction and volume between participants and chooses the closest or largest node to transact with.
As per the example use case in the recent update a Bank can run an Overledger Gateway to provide access to the various consortiums hosted on a variety of blockchains including Corda, Hyperledger Fabric and JP Morgan’s Quorum as well as access to the legacy / non-DLT platforms. Should they want to utilise a public blockchain as well in a hybrid scenario then they also have the option of using a Overledger Gateway hosted by a community member.

The Overledger Gateways contain several layers which we will explore some of their features below:

Overledger allows connection to any blockchain / DAG as well as easily integrating with existing non-DLT environments. It does this without adding the overhead of yet another blockchain / consensus in the middle, ensuring that it’s scalable and doesn’t contain a single point of failure. Nor does it require the connected blockchains to fork their code to integrate and place restrictions on what can be implemented going forward. All of this is done in a secure, trustless manner where transactions are signed and encrypted client side so the contents can’t be viewed / modified as they pass through Overledger. It currently connects all of the leading permissioned and permissionless blockchains used by enterprises today. This article explains the differences between other interoperability solutions and the benefits of Quant’s approach

The Five Ingredients of Interoperability:

Recently there was an interoperability webinar with Fintech connect with speakers such as R3’s CTO Richard Gendal Brown, along with representatives from the Bank of England, Deutsche Boerse, Nasdaq, ArchaxEx and SwissRe. Richard Gendal Brown from R3 wrote about the Five key Ingredients of Interoperability:
https://preview.redd.it/18e9wwq7zoi41.png?width=2356&format=png&auto=webp&s=537b2e70139bb0e70fcd615c497541fc89bba97f
  1. INTEGRATE with existing business systems — Businesses aren’t going to replace their existing applications for new blockchain ones, they need to integrate with their existing systems.
  2. INITIATE Payments on existing rails or blockchain rails — Needs to be able to make a payment / settlement using a wide variety of existing payment rails (off chain) as well as blockchain rails, ensuring delivery vs payment can be achieved with certainty that they have happened.
  3. INTERCHAIN applications and smart contracts that can be deployed / executed across protocols — Enabling a solution built on Corda such as Marco Polo to easily connect to a solution on another platform such as Vakt on Ethereum or CargoSmart on Hyperledger Fabric etc
  4. INTRACHAIN applications that benefit from value add of same underlying protocol — What happens when networks such as Marco Polo and Contour both running on Corda want to interoperate and the additional value and benefit that can be achieved.
  5. INTERCHANGE applications to switch platforms — What happens if you want to interchange one platform for another. Can you achieve that holy grail of interoperability by being able to be completely agnostic to the underlying platform?
Overledger meets all of these key ingredients in performing interoperability. Overledger enables existing business systems to benefit from blockchain connectivity by adding as little as 3 lines of code to their existing applications. No need to completely rewrite / replace their existing systems and all done in the most common programming languages such as Java and JavaScript.

At QuantX in December they announced Overledger Interchange which enables settlement on a variety of existing non-dlt payment rails such as Faster Payments, BACS, CHAPS, SEPA, SWIFT as well as on DLT payment rails such as with Central Bank Digital Currencies, Stablecoins and XRP. It also facilitates Cross Chain Atomic Swaps using Hash Time Locked Contracts ensuring Delivery vs Payment is achieved. Interchange is at the centre of the discussions Quant has had with traditional exchanges in capital markets and central banks and is a technology financial services have been missing and was built it address client needs.
Overledger enables interoperability within the same ecosystem such as Corda DAPP to another Corda DAPP etc as well as interoperability between any of the connected permissionless and permissioned blockchains.
Quants blockchain agnostic Operating System enables users to benefit from using the best features from different chains in combination and migrate between them, preventing Vendor or Tech Lock in without having to completely rewrite existing applications, achieving the holy grail of interoperability. It enables developers to quickly test a variety of connected blockchains in a sandbox environment to see which is best suited for their requirements, starting with just 3 lines of code.

Transactions Services Layer

https://preview.redd.it/xfthwuz9zoi41.png?width=771&format=png&auto=webp&s=8721b0ae8cff0d8aa11a484ac0ac842e700def0a
The Transaction Services layer handles more complex features of Overledger. Allowing for applications to request services such as cross-chain atomic swaps, treaty contracts (Multi Chain Smart Contracts as well as enabling smart contract functionality even on blockchains that don’t support smart contracts natively such as Bitcoin) and transaction brokering (using heuristic analysis to determine which method is the fastest / cheapest out of the various payment rails)

Financial Services Layer

https://preview.redd.it/4zgt0umazoi41.png?width=740&format=png&auto=webp&s=49a840532d70740a77c00901aafd047311b84229
Financial services features can be called upon by participants and applications to use crosschain and cross-platform. Financial Services specific use cases can use the features in Overledger to operate across networks. This layer provides enhanced privacy and security to regulated entities and institutions who require additional controls to maintain compliance to regulation and security policy. The features of Zero-knowledge Proof and privacy can be mandated for all transactions.

Channels Layer

https://preview.redd.it/ef5z0jbbzoi41.png?width=752&format=png&auto=webp&s=3fd398e0b9917e338fb6c3e0afb477d82dfeb1c8
Channels provide interoperability of services related to digital assets, payments and tokenisation. The Overledger Network allows for participants to transfer interoperate enterprise and institutional issued tokens and assets. Connect to many existing payment rails such as SWIFT, SEPA, Faster Payments etc.

Connecting Blockchain and Non-DLT Applications / Networks to Overledger

The connectors to Overledger which grant access to Overledger Network will be open source and soon be made available, allowing for anyone to create a connector and benefit from being part of the ecosystem. Currently the permissionless blockchain space is mostly speculation with little adoption, mainly due to issues that need to be resolved such as scalability, privacy and regulation with permissionless blockchains, however there are some extremely large Enterprises, Banks, Governments, even Central Banks getting heavily involved and going into production albeit mostly in the permissioned blockchain space where such issues are not a problem. Just as each Blockchain has its advantages and disadvantages, parts of Enterprise applications are better suited to Permissioned blockchains (such as more sensitive parts) and permissionless blockchains suited for a higher degree of immutability, thus a Hybrid model requiring interoperability between permissioned, permissionless as well as existing non-DLT applications is required arguably for many years ahead. Just as with cloud computing where everything didn’t suddenly just move up into the cloud, well over a decade later since the birth of the likes of Amazon AWS, hybrid is still very prevalent today with only recently the likes of central banks, banks, governments discussing moving more sensitive workloads to public clouds such as Amazon AWS, Microsoft Azure, Oracle Cloud etc.

SIA, Central Banks, Banks, Trading Venues

Quant Network partnered with SIA, a game changer for mass blockchain adoption by Financial Institutions. SIA is the leading financial network provider in Europe that connects over 570 Banks, Central Banks, Trading Venues (stock exchanges etc) to their infrastructure. They provide a dedicated private network / infrastructure for financial institutions. Every European financial institution will either connect via SIA, in partnership with Colt or via SWIFT (and in many cases they will have connectivity with both) in order to access the Eurosystem Single Market Infrastructure Gateway, granting access to all RTGS, Securities and Instant Payment transactions for Europe.
SIA have integrated Overledger into their private infrastructure covering Europe consisting of 570 supernodes called SIAChain which enables each bank, central Bank, trading venue etc to utilise Overledger for interoperability. Some of the largest deployments of blockchain are happening on SIAChain such as the Spunta project where the entire Italian Banking Sector will be using blockchain and due to go live next month. As well as the “Fideiussioni Digitali” initiative (Digital Sureties) to digitize the management of sureties using blockchain technology with the Central Bank of Italy involved.
Central Bank Digital Currencies are going to play a hugely significant role in the future and there is one central Bank currently testing Overledger and Quant are in discussions with 4 others.
Connecting your blockchain / legacy network to Overledger enables the possibility that it could be used by any of these connected Banks, Central Banks, Trading venues etc in their private network (obviously due to the amount of regulation and critical financial infrastructure the options are going to be limited on what they want to connect).

Oracle

Quant are a Fintech Partner with Oracle, the 2nd largest software company in the world and Oracle are taking Quant’s tech to their clients directly. They have 480,000 clients globally and towards the end of last year Oracle invited Quant to attend Sibos (SWIFT) where they met existing financial services and banking clients and introduced to new ones. By connecting to Overledger this also enables your solution to potentially be used by those 480,000 of Oracle’s global clients.

SIMBA Chain

SIMBA Chain is a cloud-based, smart-contract-as-a-service (SCaaS) platform, enabling users across a variety of skill sets to implement dapps (decentralized applications). The easy-to-use platform is tailored for users, developers, government, and enterprises to quickly deploy blockchain dapps for their enterprise. SIMBA Chain are developing on Quant’s Overledger Blockchain OS to allow them to deploy DAPPs across multiple connected blockchains.
SIMBA Chain have recently been awared a $9.5 million contract with the US Navy, they are also working with the US Air Force. They have a thriving ecosystem with over 1100 Organizations and 650+ Applications developed. Partners include Microsoft, Government Blockchain Association, Air Force Research Laboratory, Caterpillar, SAP and EY. Recently they also integrated Unity 3D plugin for Gaming to enable owning, storing, and managing all personal gaming assets across a variety of blockchains.
These are just a few of the companies that Quant have partnered with directly, but the ecosystem for Overledger Network is the Network of Networks. Every connected blockchain (Bitcoin, Ethereum, Ripple (XRPL), EOS, Stellar, IOTA, DAG, R3’s Corda, Hyperledger Fabric, JP Morgan’s Quorum and other Permissioned Variants of Ethereum) and their associated partners / applications built on them have the ability to connect and interoperate with the other blockchains connected as well as non-DLT networks such as existing payment rails like SWIFT, Faster Payments, SEPA etc. This Network of Network’s effects will grow exponentially as more and more join the ecosystem.
https://preview.redd.it/fd1m5uvezoi41.png?width=590&format=png&auto=webp&s=99c5b1893d851ba1effe7b5e73480c27f3f7973e

Connecting the Internet directly to blockchain

Quant Network are also developing the ability to allow developers to build MAPPs that integrate directly with the internet as well as blockchain data. They will enable this via creating a new IP address for blockchains which they are calling Quant IP which will enable traffic to be routed from an IP connection from the Internet through Overledger to the connected blockchains.
Another Quant product called Seeq is a distributed search engine that is able to search and retrieve data from multiple blockchains and display them via html directly from the blockchain. More details will be released about Seeq later this year.
Connecting the Internet directly to blockchain will allow websites to be natively created and served directly from blockchains, without the need to have, run and maintain web servers, web services, SSL certificates etc and all running in a completely trusted, extremely resilient / tamperproof environment. The implications of this are enormous and more details will be released by the team later on this exciting prospect. By connecting your blockchain to Overledger you will also be able to benefit from this.

Join your favourite Blockchain project to the Overledger Network Ecosystem

Instead of the current mentality of having the main focus for many projects of listing on exchanges for vast sums of money, why not spend a little time (connectors can be created in as little as a week of development and don’t necessarily even need to be created by the team themselves) and make your blockchain / non-DLT application available to be used by all existing enterprises / members. Not only that but if you also run an Overledger Gateway connecting your blockchain node you also benefit from the transaction fees of the traffic going to it. The connectors are open source and completely free to connect and now with the standardisation of Objects in the recent SDK update the foundations are in place for the launch of Overledger Network with an ETA of Q2 2020. If you would like your favourite blockchain project to interoperate and be part of the ecosystem to further adoption then make the relevant people aware and keep an eye out for further details released in the future.

Wall Street 2.0: How Blockchain will revolutionise Wall Street and a closer look at Quant Network’s Partnership with AX Trading
AX Trading LLC (AX), a technology-enabled registered broker-dealer and Alternative Trading System (ATS) operator, today announced a strategic partnership with Quant Network a pioneering technology company providing financial and regulatory technology as well as interoperability in financial services, payments and capital markets infrastructure. Through this partnership, Quant Network’s technology, Overledger a blockchain operating system, will enable universal interoperability for regulatory-compliant security tokens and digital assets to be traded on AX ATS, a regulated secondary trading market. AX intends to integrate Overledger to help foster the evolution of traditional capital markets infrastructure to facilitate the mass implementation of interoperable regulated digital assets. With the increased market adoption of digital assets and banking “coins” such as JPMorgan Coin, AX and Quant Network are at the forefront to enable the transferability and movement of digital assets. George O’Krepkie, AX CEO said: “we look forward to partnering with Quant. Their technology will allow our blockchain agnostic security token exchange to communicate seamlessly with issuers, traders, investors, and regulators across different blockchain protocols. This is a key technological breakthrough that will help us bring the benefits of security tokens to Main Street and Wall Street.” It is expected that the first interoperable digital asset offering may commence as soon as January 2020, and that the AX Trading ATS may be ready to enable and list interoperable digital assets and securities in 2020.
Let’s have a closer look at what that means to truly appreciate the significance of the partnership by covering the basics for those not familiar with wall street.

What is an Institutional Investor / Trader?

An institutional investor is an organization that invests on behalf of the organization's members. They consist of hedge funds, banks, investment banks, pension funds, insurance companies, endowment funds, or any other type of money management firm.
Institutional investors account for about three-quarters of the volume on the New York Stock Exchange (which alone handles more than $20 Trillion a year in volume). In the US, Institutional investors own about 80 % of the total market value of the equity (stock) market, which globally is worth more than $73 trillion.
Wall Street refers to the institutional investors I mentioned above whereas Main Street refers collectively to members of the general public who are not accredited investors and the overall economy as a whole.
Whilst the Equity Market is huge, Institutional investors also invest in other securities which are prime to be tokenised such as Real Estate Market (Globally worth $217 trillion), the Debt Market (Globally worth $215 trillion) and the Derivatives Market (Low end estimates at $544 trillion and high-end estimates at $1.2 quadrillion). All of which makes the current market cap for cryptocurrencies look like a drop in the ocean.

Who are AX Trading?

AX Trading is a SEC-registered broker-dealer and Alternative Trading System (ATS) Operator. They are a member of FINRA (Financial Industry Regulatory Authority)and SIPC ( Securities Investor Protection Corporation) regulated authorities. The SEC has some of the most stringent regulations in the world for listing securities and there are fewer than 50 SEC-registered Alternative Trading System Operators in the United States, of which only a handful are currently implementing Digital Assets. Others are awaiting regulatory approval with Coinbase, Circle etc are all looking at getting into this huge market.
https://www.coindesk.com/stonewalled-by-finra-up-to-40-crypto-securities-wait-in-limbo-for-launch
AX Trading have investors and sponsored brokers including the likes of Credit Suisse, (a multinational investment Bank and Financial services company worth $27.5 billion). AX currently have over 800 Institutional traders (these are not individuals, but corporations such as hedge funds, banks, investment banks, pension funds, insurance companies, endowment funds etc).
AX Trading have also partnered with Euronext, the largest Stock Exchange in Europe with a market cap of $4.65 trillion as of 2018, in the creation of Euronext Block which utilises AX Trading.

What is an Alternative Trading System?

An Alternative Trading System (ATS) is an SEC-regulated trading venue which serves as an alternative to trading at a public exchange. ATS account for much of the liquidity found in publicly traded issues worldwide. They are known as multilateral trading facilities in Europe, electronic communication networks (ECNs), cross networks, and call networks
AX is the world’s first “Electronic Trading Network” (ETN) where institutional traders can proactively connect and trade with other counterparties in a secure environment. Unlike traditional stock exchanges/ECNs that show orders to everyone and traditional dark pools/crossing systems that show orders — presumably — to no one, AX allows institutional traders to pick and choose WHOM they want to notify and also WHAT information they want to share with them.
Institutional investors may use an ATS to find counterparties for transactions instead of trading large blocks of shares on national stock exchanges. These actions may be designed to conceal trading from public view since ATS transactions do not appear on national exchange order books. The benefit of using an ATS to execute such orders is that it reduces the domino effect that large trades might have on the price of an equity.

How does AX Trading Work?

The AX Trading process begins when one trader sends an “initiated” order to AX. The order can be routed to the AX ATS via one of our broker sponsors such as Credit Suisse. The initiated order triggers a “Call Auction” on AX, a period of time when the order will rest in AX to be matched against other orders from auction responders.
The Initiator of an AX auction decides who they want to invite to participate in the auction, whether they be all 800+ institutional members or targeted to specific ones, as well as how much info they want to disclose about the order. Based on these instructions, the AX ATS then notifies the members inviting them to participate in the trade.
The invited members can then participate in the trade by either placing buy orders of their own or placing sell orders. At the end of the AX auction period, all orders are brought together, and a match is performed.
In the traditional, continuous market with displayed bids and offers, traders are often chasing liquidity. In other words, the price may move away from them the more they buy or sell to what is commonly called “market impact.” On AX, the advantage of their call auction model is it brings liquidity — in the form of participant orders to the buyer rather than them chasing liquidity.

What is a Security Token?

Security Tokens are different than Utility Tokens or Cryptocurrencies. A security token is a digital representation of a traditional security. It may represent shares in a company, interest in a fund, real estate, art collectables, or essentially any asset a party can own. Anthony Pompliano wrote an article explaining tokenised securities in more detail which you can see here
Security Tokens are digital assets subject to federal security regulations. In layman terms, they are the intersection of digital assets (tokens) with traditional financial products — a new technology improving old things. If cryptocurrencies like Bitcoin are considered “programmable money” then you can consider Security Tokens a version of “programmable ownership.” This means that any asset with ownership can and will be tokenized (public & private equities, debt, real estate, etc).
https://preview.redd.it/21cz6zvus0m31.png?width=569&format=png&auto=webp&s=883eb844e1061cddd585903549dde829098765c2
Quant Network community member David W also wrote an excellent piece on the benefits of tokenisation of assets in a lot more detail than what I will briefly cover here and strongly recommend you check it out.
The Tokenisation of assets is therefore inevitable, because it is a better way to record, exchange and monitor asset ownership for all parties involved. The amounts at stake represent many hundreds of trillions of US dollars

What are the benefits of a security token?

  • Lower Fees — having Smart Contracts and compliance programmed into the token itself removes the need for middlemen, reducing costs. Post Trade businesses such as clearing houses would also no longer be required further reducing costs.
  • 24/7 markets — Currently the major US stock markets trade between 9:30am and 3pm during weekdays only. Trading can be done 24/7 and globally whilst remaining compliant.
  • Fractional Ownership — This greatly increases liquidity for previously illiquid assets. Real estate, Artwork, even assets such as Oil Refineries are already in talks about being tokenised through Overledger. If you have an asset such as an oil refinery worth billions of dollars, then naturally this limits the market should you ever want to sell it. However with fractional ownership you could own a tiny percentage of it and receive profits from the oil refinery based upon the percentage you own, which exponentially increases the number ofpotential buyers, increasing liquidity.
  • Rapid Settlement — Currently it takes 3 working days to settle a securities trade, this can be reduced to minutes by having the asset and fiat represented on a blockchain and handled through smart contracts.
  • Automated compliance — Security tokens are programmable, and rules and regulations are hard-coded into the architecture of the token to ensure they always remain compliant. This means that they can be traded globally and still ensure they respect the relevant countries regulations that the participants are located in.
  • The benefits that a blockchain provide such as transparency, security, immutability, high availability. Regulators can also run a node and verify compliance in real time.

Security Token Issuance Platforms

Security token issuance platforms allow issuers to issue Security tokens that represent the security such as Shares in their company etc in return for capital. This is known as a Primary Market. Importantly it’s not just the issuance that they look after, it’s the whole life cycle of a digital security to ensure they remain continuously in compliance as they are traded etc. They also provide reporting to the issuer so they can see who owns the tokens and what dividends to pay out.
Securitize are one of the leading security tokens issuing platforms. They have created the DS Protocol, a blockchain agnostic protocol for security tokens which manages the whole lifecycle of a digital security, ensuring it remains continuously in compliance. They have issued a number of security tokens on the Ethereum network as well as recently working with IBM to tokenise the Corporate Debt Market (worth $82 Trillion). On the back of this they joined Hyperledger, an open source project which includes Enterprise blockchains such as Hyperledger Fabric which IBM is heavily involved with.
https://tokenpost.com/Quant-Network-Securitize-and-others-join-Hyperledger-blockchain-project-1544
They recently also became the first SEC-registered transfer agent, which means Securitize can now act as the official keeper of records about changes of ownership in securities.
There are many companies in this sector which are utilising various blockchains, Other examples include:
  • Harber — R Token protocol for Ethereum
  • Polymath — ST20 protocol for Ethereum
  • Blockstate — a security token issuance platform recently announced plans to migrate a number of ERC-20 tokens from the public Ethereum blockchain to the permissioned blockchain R3 Corda
  • Dusk — Uses the Dusk blockchain
  • Own — Uses the Own blockchain
And many more such as Nefund, Bankex, Capexmove, Swarm, Symbiont, Tokeny etc

Trading Venues

Whilst the issuance platforms above generally also include their own exchange where the token can be traded on, secondary markets such as those offered through traditional stock exchanges and Alternative Trading Systems provide significantly more liquidity.
Traditional Stock Exchanges have been very active in blockchain with some going through proof of concepts, to those like SIX SDX Digital Exchange which is due to launch later this year. They are using various blockchains and cover the full process from Issuance, Trading and Post Trade / Settlement services. I have briefly outlined which blockchain they are using / testing with along with source to read more about it below:

Post Trade — Central Security Depositories

Situated at the end of the post-trading process, CSDs are systemically important intermediaries. They thereby form a critical part of the securities market’s post-trade infrastructure, as they are where changes of securities ownership are ultimately registered.
CSDs play a special role both as a depository, involving the legal safekeeping and maintenance of securities in a ‘central depository’ on behalf of custodians (both in materialised or dematerialised form); as well as for the issuer, involving the issuance of further securities by issuers, and their onboarding onto CSDs’ platforms.
CSDs are also keeping a number of other important functions, including: dividend, interest, and principal processing; corporate actions including proxy voting; payment to transfer agents, and issuers involved in these processes; securities lending and borrowing; and, provide pledging of share and securities.
Blockchain technology will enable real-time settlement finality in the securities world. This could mean the end of a number of players in the post-trade area, such as central counterparty clearing houses (CCPs), custodians and others. Central Security Despositories (CSD) will still play an important role according to reports:
“CSDs could have an important role to play in a blockchain-based settlement system. As ‘custodians of the code, CSDs could exercise oversight of, and take responsibility for, the operation of the relevant blockchain protocol and any associated smart contracts.” Euroclear Report
Another group of 30 central securities depositories (CSDs) in Europe and Asia are researching possible ways to “join hands” in developing a new infrastructure to custody digital assets. The CSDs will attempt to figure out how to apply their experience in guarding stock certificates to security solutions for crypto assets.
“A new world of tokenized assets and blockchain is coming. It will probably disrupt our role as CSDs. The whole group decided we will be focusing on tokenized assets, not just blockchain but on real digital assets.”
You can read more about how blockchain will affect CSD’s here
Examples of CSD’s in blockchain
  • SIX Digital Exchange and Deutsche Borse are utilising Corda as explained in the trading venues section

The Importance Of Interoperability

The evolution of DLT and the wide adoption across industries and across different market segments is resulting in many different ledgers networks, but the ultimate promise of DLT can only be realized when all ledger networks can seamlessly interoperate. — from the recent DTCC whitepaper with Accenture
Some challenges and constraints related to the market infrastructure ecosystem remain open and will need to be addressed in the future to sustain the development of DLT platforms for trading and the post-trade process. At this stage, the questions of interoperability and standardization across these DLT (probably permissioned) platforms remain open and we may see a list of platforms offering no scope for interconnection. This will prevent them from fulfilling the key “distribution” criterion of DLT. Another related challenge that may determine whether or not the technology is adopted is the ability to provide Delivery versus Payment (DvP) settlement, in particular in central bank money. Nevertheless, it is worth mentioning that settlement can also be facilitated in commercial bank money. — https://www2.deloitte.com/content/dam/Deloitte/lu/Documents/technology/lu-token-assets-securities-tomorrow.pdf
It’s clear from the above that interoperability will be crucial in order to unlock the true potential of Distributed Ledger Technology. Issuance platforms will seek to interoperate with as many secondary exchanges as possible to provide maximum liquidity for issuers. Issuance platforms and secondary exchanges are each using a wide range of different blockchains that all need to interoperate as part of the trade process. CSD’s will also need to have interoperability between other CSD’s as well as to the secondary exchanges (again each using different blockchains).

Enter Quant Network’s Overledger

Quant Network’s blockchain operating system, Overledger, provides interoperability between any current and future distributed ledger technology as well as easily connecting Off Chain / Legacy networks as well as plans to connect directly to the Internet. Within 10 months it has proven it can provide interoperability with the full range of DLT technologies from all the leading Enterprise Permissioned blockchains such as Hyperledger, R3’s Corda, JP Morgan’s Quorum, permissioned variants of Ethereum and Ripple (XRPL) as well as the leading Public Permissionless blockchains / DAGs such as Bitcoin, Stellar, Ethereum, IOTA and EOS as well as the most recent blockchain to get added Binance Chain. All without imposing restrictions on connected chains, being Internet scalable and able to easily integrate into existing networks / infrastructure.
https://preview.redd.it/8p6hi942t0m31.png?width=1920&format=png&auto=webp&s=b0536ea9981306feb8bd95788c66e9a5727a4d58
Overledger a blockchain operating system, will enable universal interoperability for regulatory-compliant security tokens and digital assets to be traded on AX ATS, a regulated secondary trading market. AX intends to integrate Overledger to help foster the evolution of traditional capital markets infrastructure to facilitate the mass implementation of regulated digital assets. With the increased market adoption of digital assets and banking “coins” such as JPMorgan Coin, AX and Quant Network are at the forefront to enable the transferability and movement of digital assets
https://www.quant.network/blog/redefining-wall-st-with-decentralised-capital-market-infrastructure-the-possibilities-of-quant-networks-overledger-technology-in-regulated-capital-markets
Overledger enables Universal Interoperability where digital assets can move across blockchains so that they can interact with smart contracts on different blockchains. It does this by locking the asset on one blockchain and then representing it on another blockchain either by creating a representing token or representing it via metadata. This will enable all of these different parties such as Issuance platforms, Exchanges, CSD’s, traders etc to move the digital asset from their respective blockchain onto AX Trading’s platform for secure, immediate and immutable trading to take place. Potentially it would even allow Digital Assets / Securities to settled on a public permissionless blockchain such as the recently connected Binance Chain in a completely safe, secure and compliant way.
https://preview.redd.it/a3o9qxq5t0m31.png?width=443&format=png&auto=webp&s=78d7a7e7d47213bbb354336ba9d5ad92c1c2254a
Regulators would be able to run a node and view transactions in real time ensuring that compliance is being kept. Potentially they could also benefit from using Quant Networks Multichain Search capability http://search.quant.network/ to be able to fully track assets as they move across blockchains.
George O’Krepkie, AX CEO said: “we look forward to partnering with Quant. Their technology will allow our blockchain agnostic security token exchange to communicate seamlessly with issuers, traders, investors, and regulators across different blockchain protocols. This is a key technological breakthrough that will help us bring the benefits of security tokens to Main Street and Wall Street.”

Securrency

AX Trading have also partnered with Securrency (who have previously tokenised over $260 million in real estate assets). Securrency provide a protocol that enables security tokens to remain in compliance regardless of what blockchain the token is on. Due to the layered approach that Overledger has adopted from the learnings of TCP/IP, this protocol can be easily integrated on top of Overledger to enable security tokens to move across blockchains as well as ensuring they remain in compliance with regulations programmed into the token.

Delivery vs Payment (DvP)

A DvP transaction involves the settlement of two linked obligations, namely the delivery of securities and the payment of cash. DvP avoids counterparties being exposed to principal risk, i.e. the risk that the seller of securities could deliver but would not receive payment or that the buyer of securities could make payment but would not receive delivery. Following this requirement, a DvP securities settlement mechanism has to ensure that the delivery of securities and the payment of cash are linked in a way where one leg (obligation) of the securities trade is conditioned to the final settlement of the other leg (obligation) of the trade. Thereby final settlement is defined as “the irrevocable and unconditional transfer of an asset or financial instrument, or the discharge of an obligation by the FMI or its participants in accordance with the terms of the underlying contract”. — STELLA — a joint research project of the European Central Bank and the Bank of Japan
We have seen how Overledger can provide interoperability for the securities to move across Issuers platforms, integrate with Stock exchanges, Central Security Depositories and AX Trading. Now we need to be able to ensure that payment is guaranteed and in a way that offers immediate settlement which is irrevocable. To do this we need to represent FIAT on the blockchain so that it can interact with smart contracts and settle transactions on the blockchain.

J.P.Morgan’s Coin

J.P.Morgan is the largest bank in the United States and ranked by S&P Global as the sixth largest bank in the world by total assets as of 2018, to the amount of $2.535 trillion.
J.P. Morgan was the first U.S. bank to create and successfully test a digital coin representing a fiat currency. The JPM Coin is based on blockchain-based technology enabling the instantaneous transfer of payments between institutional clients.
With J.P.Morgan’s $2.6 trillion balance sheet, expertise in blockchain and global payments network, J.P. Morgan can seamlessly and securely transfer and settle money for clients around the world. J.P. Morgan are supervised by banking regulators in the United States and in the international jurisdictions in which it operates.

How does JPM Coin work?

A Buyer purchases JPM coins in advance which get represented on the Permissioned Quorum blockchain ($1 =1 JPM Coin). Quant Network’s Overledger could then provide interoperability to lock those tokens on Quorum and represent those onto another blockchain / AX Trading’s Network. By being able to represent securities and FIAT on the same blockchain (even though the underlying assets are on different blockchains) this provides instant finality / settlements to occur.
Once the seller receives the JPM coin in exchange for the securities they have sold they will be able to redeem them for USD. It also doesn’t necessarily mean that they have to have a JP Morgan account to redeem them, you could imagine in the future that the Bank instead redeems the JPM Coin and credits the users account. Similarly the buyer of the security token redeems the represented token and unlocks the security token on the original blockchain.
You can read more about JP Morgan’s Coin here as well as its use cases
J.P Morgan is betting that its first-mover status and large market share in corporate payments — it banks 80 percent of the companies in the Fortune 500 — will give its technology a good chance of getting adopted, even if other banks create their own coins. “Pretty much every big corporation is our client, and most of the major banks in the world are, too,” Farooq said. “Even if this was limited to JPM clients at the institutional level, it shouldn’t hold us back.”
Overledger enables different securities tokens / digital coins representing FIAT currencies to be brought together from the various permissioned / permissionless blockchains onto one platform where trading / settlement can take place. Overledger is the only technology that can do this today across the leading permissioned and permissionless blockchains as well as existing networks, all in a secure, scalable and easy to integrate way.

Large Enterprise Adoption of Blockchain is happening, enabled by Quant Network’s Overledger

Large Enterprise Adoption of Blockchain is happening, enabled by Quant Network’s Overledger
https://medium.com/@CryptoSeq/large-enterprise-adoption-of-blockchain-is-happening-enabled-by-quant-networks-overledger-32321b650115
This is Part Two in the mini-series looking at Quant Network. You can see Part One here as well as links to other articles at the bottom of this post.
Quant Network have achieved incredible levels of adoption since launching Overledger less than a year ago. Their growth strategy is to partner with multinational global organisations with huge amounts of employees to then host / implement / take Overledger to each of their own clients. So one Partnership, leads to exponentially more and is the fastest way to scale rather than trying to partner with each customer individually. This is how companies such as Oracle grew so fast and Microsoft with their Partner Network.
These are multinational global organisations with 100,000 + employees, this is the scale that we are working towards to take Overledger to the mass market. We can’t do it one by one in each country and sign them up but we can partner with someone that has 100 customers and they can take it to all their customers as well which helps with the adoption of our technology” — Gilbert Verdian
Let’s start with arguably the biggest partnership for any Blockchain company listed on Coinmarketcap, the leading Financial Network Provider in Europe, SIA.

SIA

  • Provide the leading Financial Network in Europe with more than 100 Tier 1 banks connected, 44 Trading venues (including the main international stock markets in Milan, Rome, London, Frankfurt and New York) and other financial institutions covering the entire trading process from pre-trading to post-trading
  • process 14 Billion institutional services transactions, 7.2 billion card transactions, 3 billion payments, 51.7 billion financial transactions and carried 1,204 terabytes of data on the network
  • SIA in partnership with Colt and SWIFT are the only two network providers awarded a 10 year tender commissioned by the European Central Bank for the provisioning of connectivity services allowing European central and commercial banks, central depositories, automated clearing houses and other payment service providers to connect directly to Eurosystem market infrastructures through a single access interface (Eurosystem Single Market Infrastructure Gateway — ESMIG).
  • SIA’s SIAchain is the leading blockchain architecture in Europe connecting 570 Banks, Central Banks, Trading Venues and other Financial Institutions using R3’s Corda, Permissioned variants of Ethereum and Hyperledger Fabric.
  • SIA have Integrated Overledger into the leading blockchain architecture in Europe SIAchain so that all of the 570 banks, Central Banks, Trading venues etc can benefit from Blockchain Interoperability.
“Since the European launch of our private infrastructure SIAchain, we are at the forefront of innovation in blockchain technology with the aim of supporting financial markets with a high-performance and secure architecture and a clear governance model. We actively continue on our path of innovation and the achievement of a fully interoperable blockchain network is the foremost objective we want to reach with the collaboration of Quant Network and its disruptive vision on DLT”, says Daniele Savarè, Innovation & Business Solutions Director, SIA.
https://youtu.be/0cNmGrLPoTo
So what we’ve done is instead of just announcing one client and one thing, we’re announcing that we’re working with SIA. So, SIA is the leading European payment infrastructure. And what we’re doing with SIA is interconnecting blockchain networks with SIA, and doing settlements, which are central bank settlements, with the central bank in Italy. So what Overledger is doing is we’re actually bringing blockchain and interoperability to all of SIA’s clients, which are 580 banks. So, Overledger could be rolled out to all these institutions, financial services, banks, at scale, and have interoperability to get the benefits of this.

  • an SEC-registered broker-dealer and Alternative Trading System (ATS) Operator. They are a member of FINRA and SIPC regulated authorities.
  • Have investors and sponsored brokers such as Credit Suisse, (a multinational investment Bank and Financial services company worth $27.5 billion).
  • AX currently have over 800 Institutional traders (these are not individuals, but corporations such as hedge funds, banks, investment banks, pension funds, insurance companies, endowment funds etc).
  • AX Trading have also partnered with Euronext, the largest Stock Exchange in Europe with a market cap of $4.65 trillion as of 2018, in the creation of Euronext Block which utilises AX Trading.
  • This is a multi-trillion dollar market with huge global enterprises, traditional exchanges and global banks are all adopting DLT at a rapid pace and going into production at scale in a matter of months
Overledger a blockchain operating system, will enable universal interoperability for regulatory-compliant security tokens and digital assets to be traded on AX ATS, a regulated secondary trading market. AX intends to integrate Overledger to help foster the evolution of traditional capital markets infrastructure to facilitate the mass implementation of regulated digital assets. With the increased market adoption of digital assets and banking “coins” such as JPMorgan Coin, AX and Quant Network are at the forefront to enable the transferability and movement of digital assets
George O’Krepkie, AX CEO said: “we look forward to partnering with Quant. Their technology will allow our blockchain agnostic security token exchange to communicate seamlessly with issuers, traders, investors, and regulators across different blockchain protocols. This is a key technological breakthrough that will help us bring the benefits of security tokens to Main Street and Wall Street.”

My growing collection of info about NEO

It can be very time consuming to keep up to date on a single blockchain project let alone multiple ones. If you just heard about NEO a few weeks ago it would be impossible catch up on past occurrences due to high volume of Reddit posts and articles made on the project. I’m going to try and simplify the past, present and future as much as I can into one well thought-out post. I hope I can be helpful to anyone who has been investigating like myself. I will include sources with all of my research.
https://imgur.com/a/NBI7S (img for mobile backround)
Key notes from the White Paper http://docs.neo.org/en-us/
Digital Assets
Digital assets are programmable assets that exist in the form of electronic data. With blockchain technology, the digitization of assets can be decentralized, trustful, traceable, highly transparent, and free of intermediaries. On the NEO blockchain, users are able to register, trade, and circulate multiple types of assets. Proving the connection between digital and physical assets is possible through digital identity. Assets registered through a validated digital identity are protected by law.
Digital Identity
Digital identity refers to the identity information of individuals, organizations, and other entities that exist in electronic form. The more mature digital identity system is based on the PKI (Public Key Infrastructure) X.509 standard. In NEO, we will implement a set of X.509 compatible digital identity standards. This set of digital identity standards, in addition to compatible X.509 level certificate issuance model, will also support Web Of Trust point-to-point certificate issuance model. Our verification of identity when issuing or using digital identities includes the use of facial features, fingerprint, voice, SMS and other multi-factor authentication methods.
Smart Contracts
The NeoContract smart contract system is the biggest feature of the seamless integration of the existing developer ecosystem. Developers do not need to learn a new programming language but use C#, Java and other mainstream programming languages in their familiar IDE environments (Visual Studio, Eclipse, etc.) for smart contract development, debugging and compilation. NEO's Universal Lightweight Virtual Machine, NeoVM, has the advantages of high certainty, high concurrency, and high scalability. The NeoContract smart contract system will allow millions of developers around the world to quickly carry out the development of smart contracts.
Economic Model
NEO has two native tokens, NEOand NeoGas NEO represents the right to manage the network. Management rights include voting for bookkeeping, NEO network parameter changes, and so on. The minimum unit of NEO is 1 and tokens cannot be subdivided. GAS is the fuel token for the realization of NEO network resource control. The NEO network charges for the operation and storage of tokens and smart contracts, thereby creating economic incentives for bookkeepers and preventing the abuse of resources. The minimum unit of GAS is 0.00000001.
Distribution Mechanism
NEO's 100 million tokens are divided into two portions. The first portion is 50 million tokens distributed proportionally to supporters of NEO during the crowdfunding. This portion has been distributed.
The second portion is 50 million NEO managed by the NEO Council to support NEO's long-term development, operation and maintenance and ecosystem. The NEO in this portion has a lockout period of 1 year and is unlocked only after October 16, 2017. This portion WILL NOT enter the exchanges and is only for long-term support of NEO projects. The plans for it are as below:
▪ 10 million tokens (10% total) will be used to motivate NEO developers and members of the NEO Council
▪ 10 million tokens (10% total) will be used to motivate developers in the NEO ecosystem
▪ 15 million tokens (15% total) will be used to cross-invest in other block-chain projects, which are owned by the NEO Council and are used only for NEO projects
▪ 15 million (15% total) will be retained as contingency
▪ The annual use of NEO in principle shall NOT exceed 15 million tokens
GAS distribution
GAS is generated with each new block. The initial total amount of GAS is zero. With the increasing rate of new block generation, the total limit of 100 million GAS will be achieved in about 22 years. The interval between each block is about 15-20 seconds, and 2 million blocks are generated in about one year. According to this release curve, 16% of the GAS will be created in the first year, 52% of the GAS will be created in the first four years, and 80% of the GAS will be created in the first 12 years. GAS will be distributed proportionally in accordance with the NEO holding ratio, recorded in the corresponding addresses. NEO holders can initiate a claim transaction at any time and claim these GAS tokens at their holding addresses.
Consensus mechanism: dBFT
The dBFT is called the Delegated Byzantine Fault Tolerant, a Byzantine fault-tolerant consensus mechanism that enables large-scale participation in consensus through proxy voting. The holder of the NEO token can, by voting, pick the bookkeeper it supports. The selected group of bookkeepers, through BFT algorithm, reach a consensus and generate new blocks. Voting in the NEO network continues in real time, rather than in accordance with a fixed term.
Cross-chain assets exchange agreement
NeoX has been extended on existing double-stranded atomic assets exchange protocols to allow multiple participants to exchange assets across different chains and to ensure that all steps in the entire transaction process succeed or fail together. In order to achieve this function, we need to use NeoContract function to create a contract account for each participant. If other blockchains are not compatible with NeoContract, they can be compatible with NeoX as long as they can provide simple smart contract functionality.
Cross-chain distributed transaction protocol
Cross-chain distributed transactions mean that multiple steps of a transaction are scattered across different blockchains and that the consistency of the entire transaction is ensured. This is an extension of cross-chain assets exchange, extending the behavior of assets exchange into arbitrary behavior. In layman's terms, NeoX makes it possible for cross-chain smart contracts where a smart contract can perform different parts on multiple chains, either succeeding or reverting as a whole. This gives excellent possibilities for cross-chain collaborations and we are exploring cross-chain smart contract application scenarios.
Distributed Storage Protocol: NeoFS
NeoFS is a distributed storage protocol that utilizes Distributed Hash Table technology. NeoFS indexes the data through file content (Hash) rather than file path (URI). Large files will be divided into fixed-size data blocks that are distributed and stored in many different nodes
Anti-quantum cryptography mechanism: NeoQS
The emergence of quantum computers poses a major challenge to RSA and ECC-based cryptographic mechanisms. Quantum computers can solve the large number of decomposition problems (which RSA relies on) and the elliptic curve discrete logarithm (which ECC relies on) in a very short time. NeoQS (Quantum Safe) is a lattice-based cryptographic mechanism. At present, quantum computers do not have the ability to quickly solve the Shortest Vector Problem (SVP) and the Closest Vector Problem (CVP), which is considered to be the most reliable algorithm for resisting quantum computers.
Reasons for choosing dBFT over PoW and PoS:
With the phenomenal success of Bitcoin and its increasing mainstream adoption, the project’s unbounded appetite for energy grew accordingly. Today, the average Bitcoin transaction costs as much energy as powering 3.67 average American homes, which amounts to about 3000 times more than a comparable Credit Card settlement.
This mind boggling amount of energy is not, as it is commonly believed, being wasted. It is put to good use: securing the Bitcoin network and rendering attacks on it infeasible. However, the cost of this security mechanism and its implications for an increasingly warming and resource hungry planet led almost the entire crypto industry to the understanding that an alternative has to be found, at least if we’re interested in seeing blockchain technology gaining overwhelming mainstream adoption.
The most popular alternative to PoW, used by most alternative cryptocurrency systems, is called Proof-of-Stake, or PoS. PoS is highly promising in the sense that it doesn’t require blockchain nodes to perform arduous, and otherwise useless, cryptographic tasks in order to render potential attacks costly and infeasible. Hence, this algorithm cuts the power requirements of PoS blockchains down to sane and manageable amounts, allowing them to be more scalable without guzzling up the planet's energy reserves.
As the name suggests, instead of requiring proof of cryptographic work, PoS requires blockchain nodes to proof stake in the currency itself. This means that in order for a blockchain node to be eligible for a verification reward, the node has to hold a certain amount of currency in the wallet associated with it. This way, in order to execute an attack, a malevolent node would have to acquire the majority of the existing coin supply, rendering attacks not only costly but also meaningless, since the attackers would primarily harm themselves.
PoS, as well as PoW, simply cause the blockchain to fork into two alternative versions if for some reason consensus breaks. In fact, most blockchains fork most of the time, only to converge back to a single source of truth a short while afterwards.
By many crypto enthusiasts, this obvious bug is very often regarded as a feature, allowing several versions of the truth to survive and compete for public adoption until a resolution is generated. This sounds nice in theory, but if we want to see blockchain technology seriously disrupt and/or augment the financial sector, this ever lurking possibility of the blockchain splitting into two alternative versions cannot be tolerated.
Furthermore, even the fastest PoS blockchains out there can accomodate a few hundred transactions per second, compare that to Visa’s 56,000 tx/s and the need for an alternative becomes clear as day.
A blockchain securing global stock markets does not have the privilege to fork into two alternative versions and just sit and wait it out until the market (or what’s left of it) declares a winner. What belongs to whom should be engraved in an immutable record, functioning as a single source of truth with no glitches permitted.
After investigating and studying the crypto industry and blockchain technologies for several years, we came to the conclusion that the delegated Byzantine Fault Tolerance alternative (or dBFT) is best suited for such a system. It provides swift transaction verification times, de-incentivises most attack vectors and upholds a single blockchain version with no risk of forks or alternative blockchain records emerging - regardless of how much computing power, or coins an attacker possesses.
The term Byzantine Fault Tolerance (BFT) derives its name from the Byzantine Generals problem in Game Theory and Computer Science, describing the problematic nature of achieving consensus in a distributed system with suboptimal communication between agents which do not necessarily trust each other.
The BFT algorithm arranges the relationship between blockchain nodes in such a way that the network becomes as good as resilient to the Byzantine Generals problem, and allows the system to remain consensus even if some nodes bare malicious intentions or simply malfunction.
To achieve this, Antshare’s version of the delegated BFT (or dBFT) algorithm acknowledges two kinds of players in the blockchain space: professional node operators, called bookkeeping nodes, who run nodes as a source of income, and users who are interested in accessing blockchain advantages. Theoretically, this differentiation does not exist in PoW and most PoS environments, practically, however, most Bitcoin users do not operate miners, which are mostly located in specialized venues run by professionals. At Antshares we understand the importance of this naturally occurring division of labor and use it to provide better security for our blockchain platform.
Accordingly, block verification is achieved through a consensus game held between specialized bookkeeping nodes, which are appointed by ordinary nodes through a form of delegated voting process. In every verification round one of the bookkeeping nodes is pseudo-randomly appointed to broadcast its version of the blockchain to the rest of the network. If ⅔ of the remaining nodes agree with this version, consensus is secured and the blockchain marches on. If less than ⅔ of the network agrees, a different node is appointed to broadcast its version of the truth to the rest of the system, and so forth until consensus is established.
In this way, successful system attacks are almost impossible to execute unless the overwhelming majority of the network is interested in committing financial suicide. Additionally, the system is fork proof, and at every given moment only one version of the truth exists. Without complicated cryptographic puzzles to solve, nodes operate much faster and are able to compete with centralized transaction methods.

OnChain
It is important to note the technical difference between Onchain and NEO. Onchain is a private VC-backed company with over 40 employees. NEO is a public platform with different community-led groups contributing to this public project. There exists NEO council comprised of the original NEO creators, employees from Onchain, full time NEO council members and there is also the first Western based group called City of Zion. This confusion is likely the source of the rumour about Antshares and Alibaba having a connection. Onchain and NEO are separate entities who are intimately related via cross-chain communications and similar designs.
Onchain, a Shanghai-based blockchain R&D company, first started developing Antshares in February of 2014 which will eventually become the foundation of DNA. Onchain was founded by CEO Da HongFei and CTO Erik Zhang in response to the attention from private companies garnered by the development of Antshares, China’s first public blockchain. In contrast to the weeks-old start-ups launching ICOs that is happening currently in the blockchain world, it took them 22 long months of R&D to even begin providing services to their first customers. Finally, in April 2016, the first whitepaper on consensus protocol from China was born — the dBFT (delegated Byzantine Fault Tolerance) protocol.
2016 was a busy year for Onchain and they really picked up the pace that year. Other than continuing the development of Antshares, brushing shoulders with Fortune 500 companies, Onchain became the first Chinese blockchain company to join Hyperledger — an open source blockchain project started by the Linux Foundation specifically focusing on the development of private and consortium chains for businesses. It is here where the Da HongFei and Erik Zhang, entered the hyperbolic time chamber that is now known as Fabric, a platform by Hyperledger for distributed ledger solutions, and has consequently helped them to develop many aspects underpinning the design of DNA.
In June of 2016, during the first of many future partnerships with Microsoft China, Onchain founded Legal Chain specifically targeting the inadequacies of the digital applications within the legal system. In 2005, (Digital Signature Act) was passed into national law which permitted an effective digital signatures to gain the same legal rights as a real signature.
In company with Microsoft China, they are also aiming to integrate the technology with Microsoft’s face and voice recognition API function to kick start this digital revolution within the legal system. At the same time, a partnership was formed with FaDaDa, a third-party platform for electronic contracts that has processed over 27 million contracts to date, to provide secure evidence storage with DNA. If that’s not enough, they were also voted as KPMG’s top 50 Fintech Company in China and established a relationship with the Japanese Ministry of Economy, Trade and Industry which led to the recent tour to Japan. Finally, at the end of 2016 they announced a partnership with Alibaba to provide attested email service for Ali Cloud with Legal Chain where it provides a proof-of-existence for a blockchain-powered email evidence repository for enterprise-level use.
Fosun Group, China’s largest private conglomerate, have recently invested into Onchain in order to apply DNA across all of its businesses. Currently, Fosun International has a market cap of 102.98 billion dollars on the Hong Kong Stock Exchange and that is only its international branch.
The role of Onchain so far is reminiscent of Ethereum’s EEA in addition to a stronger emphasis of governmental cooperation. Onchain has identified the shortcomings of present laser focus of hype on public platforms such as NEO and Ethereum and addressing that with DNA. DNA envisions a future where a network of assorted, specifically designed blockchains serving private enterprises, consortiums, government and the public communicating with each other forming an interconnected blockchain network.
This is the goal of DNA — infiltrating every little inefficient niche that had no better alternatives before the invention of blockchain. What is especially critical to remember during this explosive time of hype driven partly by the obscene degree of greed is that not every little niche that blockchain can fill will be holding its own little ICO for you to “go to the moon on your rocket powered lambos”. Some of those efficiencies gained will simply be consumed by companies privately or by public systems such as the legal system.

Networks proves itself with the first ICO
ICOs, on other platforms such as Ethereum, often resulted in a sluggish network and transaction delays. While NEO’s dBFT consensus algorithm is designed to achieve consensus with higher efficency and greater network throughputt, no amount of theoretical calculations can simulate the reality of real-life conditions.
--Key Observations--
Smart Contract Invocations:
A total of 13,966 smart contracts invocations were executed on the NEO network over this time period, of which, nearly all called the RPX smart contract method mintTokens. A total of 543,348,500 RPX tokens were successfully minted and transferred to user accounts, totalling 10,097 smart contract executions.
Refunded Invocations:
A total of 4182 refund events were triggered by the smart contract method mintTokens. (Note: RPX has stated that these refunds will be processed within the next two weeks.)
Crowdsale statistics:
A successful mintTokens execution used around 1043 VM operations, while an execution that resulted in a refund used 809 VM operations. Within the hour and six minutes that the token sale was active, a total of 12,296,409 VM operations were executed. A total of 9,575 unique addresses participated in the RPX ICO. Half of these, approximately 4,800 unique addresses, participated through CoZ’s Neon wallet. The top 3 blocks with the most transactions were block 1445025 (3,242 transactions), block 1444902 (2,951 transactions), and block 1444903 (1609 transactions).
Final Thoughts
At the moment, the consensus nodes for the NEO network are operated by the NEO Council in China. By Q1 2018, NEO Council aims to control less than two-thirds of the consensus nodes.
We are pleased to note that the NEO network continuted to operate efficiently with minimal network impact, even under extreme network events. Block generation time initially slowed down to 3 minutes to process the largest block, but quickly recovered to approximately 25 seconds. Throughout the entire RPX ICO, consensus nodes were able to achieve consensus and propagate new block transactions to the rest of the network. In closing, while we consider this performance to be excellent, NEO Council and City of Zion areworking closely together on upgrades, that will increase the throughputs of the NEO network.
