Abstract
As the most successful cryptocurrency to date, Bitcoin constitutes a target of choice for attackers. While many attack vectors have already been uncovered, one important vector has been left out though: attacking the currency via the Internet routing infrastructure itself. Indeed, by manipulating routing advertisements (BGP hijacks) or by naturally intercepting traffic, Autonomous Systems (ASes) can intercept and manipulate a large fraction of Bitcoin traffic. This paper presents the first taxonomy of routing attacks and their impact on Bitcoin, considering both small-scale attacks, targeting individual nodes, and large-scale attacks, targeting the network as a whole. While challenging, we show that two key properties make routing attacks practical: (i) the efficiency of routing manipulation; and (ii) the significant centralization of Bitcoin in terms of mining and routing. Specifically, we find that any network attacker can hijack few (<100) BGP prefixes to isolate ~50% of the mining power---even when considering that mining pools are heavily multi-homed. We also show that on-path network attackers can considerably slow down block propagation by interfering with few key Bitcoin messages. We demonstrate the feasibility of each attack against the deployed Bitcoin software. We also quantify their effectiveness on the current Bitcoin topology using data collected from a Bitcoin supernode combined with BGP routing data. The potential damage to Bitcoin is worrying. By isolating parts of the network or delaying block propagation, attackers can cause a significant amount of mining power to be wasted, leading to revenue losses and enabling a wide range of exploits such as double spending. To prevent such effects in practice, we provide both short and long-term countermeasures, some of which can be deployed immediately.

Monero Missives
June 27th, 2014
Hello, and welcome to our fourth Monero Missive!
Major Updates
  1. This week's Missive has been a little slow in coming because fluffypony has been en-route to Estonia to represent Monero at the Bitcoin Supernode Conference in Malla Castle. Thankfully, he has arrived safely, and the conference starts today (nickname'd and all). If you'd like to keep tabs on him over the next three days, he will be Tweeting as the conference progresses: http://twitter.com/fluffyponyza/
  2. Just in case you weren't aware, XMR has been added to two exchanges: BTer and MintPal!
  3. Work continues on the annotated CryptoNote whitepaper, the latest version of which can be found here: http://monero.cc/downloads/whitepaper_annotated.pdf. We have also begun a parallel analysis of the implementation of the concepts in the Monero code (most especially as it has been inherited from the reference implementation).
  4. We caught a bug where restoring a deterministic wallet would not find old transactions. This was due to the assumption that is made by simplewallet that a newly "created" wallet will never have old transactions in it. This has been patched, and will be merged up to master and included in updated binaries from the beginning of next week.
  5. We've been putting a lot of emphasis on making Monero a lot more stable and usable by pools, merchant systems, and exchanges. More details on our ongoing efforts in the dev diary below!
  6. Transaction auto-splitting has been testing quite well, and is just about ready to be included in the main codebase (subsequent to a few minor changes on the RPC side).
Dev Diary
Miner: huge changes to add AES-NI support in slow_hash
Core: tx auto-split testing successful, auto-split RPC call needs to have payment ID support added before being merged into master
Core: major overhaul to the daemon is in progress in mikezackles' repo (https://github.com/mikezackles/bitmonero/tree/daemonize). Currently this is Linux / OS X only, and allows for the daemon to fork to the background properly (whilst still allowing daemon commands to be executed against it). Windows support by means of a Windows service will come later.
Core: along the same lines, simplewallet has been split out into simplewallet (CLI) and rpcwallet (stand-alone RPC daemon), ongoing work is on tewinget's branch (https://github.com/tewinget/bitmonero/tree/rpcwallet).
Until next week!

Monero Missives
June 10th, 2014
Hello XMR users! Welcome to our second Monero Missives.
Major Updates
  1. We're happy to introduce a major new feature for Monero: deterministic wallets based on a mnemonic seed! When creating a new wallet you now get a 24 word seed that you can use to restore the wallet. Usage: This affects simplewallet, and is the default behaviour for --generate-new-wallet. If you would like to disable the deterministic seed during wallet generation, you can pass the --non-deterministic flag. To restore from a seed you can use the --restore-deterministic-wallet flag. This provides a MAJOR benefit in that backing up your wallet no longer requires backing up the .bin.keys file! All you have to do is write down the 24 words and that's the only backup you need. If you're particularly brave you can even memorise the 24 words. You can also use this to create an offline cold wallet or a paper wallet: create a wallet on a computer disconnected from the Internet, write the 24 words and the address and the view key down, and then remove all the files created by the wallet. Security notes: Please note that this key is independent of your password. By default the 24 word key is written to simplewallet.log when the wallet is created. This is the expected behaviour, the next release will both exclude this from the log and reduce the default log level. Please run --generate-new-wallet with the --set_log 0 flag, or alternatively make sure to delete the simplewallet.log file afterwards. Technical details: The key length for this remains 256-bits and thus does not compromise user security. The view key seed is generated from a keccak1600 hash of the spend key (which is directly from the mnemonic seed), hence the deterministic nature of this. The non-deterministic method is still available as an option. How to get it: binaries in the OP have already been updated, or you can compile from the source on github. Moving to a deterministic wallet: unfortunately it's not possible to retroactively make an existing wallet deterministic. If you want to take advantage of the new feature, you will have to create a new wallet and move your funds in there.
  2. XMR is now on Mintpal for voting. You can find the voting link here: https://www.mintpal.com/voting#XMR - Mintpal allows 1 vote an hour from registered users who have traded before, as well as paid-for votes.
  3. Monero will be officially represented by fluffypony at the Bitcoin Supernode Conference at Malla Castle in Estonia at the end of this month.
  4. Neozaru has made great strides in his RPC-based Qt GUI wallet, and it requires some testing. If you are keen on trying it out, head over to his comment the GUI thread, give it a spin, and give him feedback.
Dev Diary
RPC: incoming_transfers is now available as a simplewallet RPC API call, and payment_id has been added as an optional argument to the transfer RPC API call. Neozaru also committed a large amount of additional functionality to the RPC API, including progress estimation to getinfo.
I2P: no commits this week, much of the work has been around scoping and planning the RPC subsystem.
Core: new seed nodes have been added, so bootstrapping on cold start should work just fine. We are going to add DNS seed node bootstrapping at a later stage.
Docs: work has begun on adding Doxygen comments throughout the code. This will both help us to understand the code written by "The CryptoNote Developers" (who appear at the top of every piece of source code except for the epee library), but will also result in proper developer documentation being made available.
Mining: Wolf` has continued to improve his CPU miner - the latest copy of which can be found on his github repo.
Mining: Claymore released a CryptoNight GPU miner, which you can find at this thread. Please be advised that his miner is currently closed source, and the appropriate level of caution should be exercised.
Until next week!
PS. If you've made it this far, there's a reward in the example wallet listed in the screenshot - first to grab it gets the prize!

Hello, and welcome to our fifth Monero Missive!
Major Updates
  1. fluffypony had a great time discussing Monero at the Bitcoin Supernode Conference in Estonia. Many thanks to rpietila for hosting him and all attendees.
  2. Work on the academic peer review of the CryptoNote whitepaper is slowly starting to move away from an academic platform and on to the code itself, to determine whether the reference implementation correctly implements the whitepaper. Before that happens, though, a summary of the initial findings will be published. We are expecting this to be completed this coming week.
  3. Transaction auto-splitting is now in the main codebase. To explain our methodology: the main github repo will always be "active development", and may contain code that will be reverted or is not fully tested. For those that are brave and want to test and contribute to development, it is the ideal starting point. However, on an ongoing basis we are going to create tagged releases, whereby when a group of new features have been fully tested, a new release can be tagged, and binaries can be put out (along with the code on the github tag, of course). Expect this change to start taking effect within the next 4 weeks.
  4. We'd like to apologise for not finalise the GUI bounty - everyone has been a little scattered this week. We will resolve this in its entirety within the next 48 hours!
Dev Diary
Core: daemonizing changes are ready for testing: https://github.com/mikezackles/bitmonero/tree/daemonize
Core: rpcwallet is ready for testing: https://github.com/tewinget/bitmonero/tree/rpcwallet
This Missive is a little light on major updates (well, we can't have something major every week;) primarily because there has been lots of plotting and planning this week. As always: you can keep up to date with the nitty-gritty on IRC in #monero-dev on Freenode if you're interested.
Until next week!

Bitcoin as a live action alternate reality roleplaying game

This game was created by Duke Risto Pietila.
https://bitcointalk.org/index.php?topic=232802.0
"Do you want to just update your life? Start to live in the age of great men and great machines, intertwined with the modern communication technology. Then Bitcoin Supernode Game is for you. The more you buy bitcoins, the more important role you will have in the world, as bitcoin relentlessly rises above its true value of around [$300,000 / BTC] and comes back. The Bitcoin Supernode Game eases in the transition - you are already acting as a ruler, so it is possible that you will be promoted even above your actual holdings when everybody sees that Bitcoin is the thing."
Buy 1 bitcoin and become a respectable Freeman 1st Class.
Three bitcoins and you can join the ranks of the lesser nobility as a Knight.
Hold 100 bitcoins and join the ranks of the high nobility as a Viscount. 100 bitcoins guarantees yourself a position among the top 210,000 holders of bitcoin (but will more likely hold a position among the top 15,000 holders accounting for lost bitcoin and large holders).
Whatever you do, don't ever let yourself join the ranks of the Destitute.
We are the new wealthy elite, ladies and gentlemen. Time to start acting like it. This is the most fun game you'll ever play.

Comprehensive Introduction of Polkadot-Overview (1)

Comprehensive Introduction of Polkadot-Overview (1)

https://preview.redd.it/06ymt5bt6eg51.jpg?width=1200&format=pjpg&auto=webp&s=8d5c6134ae3096182d913a09ce29e952b8b9f4f1
I have been planning to write a series of articles to comprehensively introduce Polkadot for a long time. Unfortunately, I didn't know enough at the time. After long-term research, I got a systematic understanding of Polkadot. Meanwhile, I found that the more I study, the more excited I am, and the more I can realize the greatness of Polkadot. If you are a DOT holder, you must also want to know what is so great about this huge blockchain giant that has been honed by former Ethereum CTO Gavin Wood for three years. If you don’t know much about blockchain technology, you basically can’t understand a project by reading the white paper only. As Polkadot’s preacher and the most steadfast believer in blockchain, it seems necessary to me to conduct a series of articles about Polkadot. As My fans, I believe you all know very well that my articles can basically be understood by anyone who even have no basic knowledge. So, please read it carefully. After all, you can't hold your token without knowing it. Even if DOT can rise to more than 10 thousand USD one day, you will most likely get off the train halfway.

1. Why Do We Need Polkadot?
When Satoshi Nakamoto invented Bitcoin, because the total amount of Bitcoin was constant, the process of using a computer to mine Bitcoin was just like mining gold in reality, which required a lot of power resources. Therefore, people regard Bitcoin as digital gold, which has the effect of scarcity and value preservation. People are happy to exchange part of their legal currency into Bitcoin, believing that Bitcoin can live with human civilization and that your assets will not be diluted by the over-issuance of legal currency.

This is the era of blockchain 1.0.

Bitcoin, as the first decentralized currency, can be transferred from point-to-point. However, people find that the flow of Bitcoin cannot be executed according to the contract. For example, Smith pledged 1 Bitcoin to Jones to lend $10,000.00 US dollars. Then when Smith returns Jones $10,000.00, Jones should return the pledged 1 Bitcoin to Smith. The question is, what if Jones pull back and refusing returning the Bitcoin?
Later, everyone knows that Vitalik Buterin invented Ethereum, through which people can freely mint tokens on the chain and control the flow of these tokens with codes through smart contracts. With smart contracts, the above example can be easily solved. Smith only needs to pledge 100 ETH to the contract to lend 10,000 USDT. Later, when Smith transfers 10,000 USDT back to the contract, the contract will return 100 ETH to Smith.

This is the era of blockchain 2.0.

Ethereum is known as the world computer, and people can freely write smart contracts to control the flow of value, which enables decentralized finance (DEFI) to flourish on Ethereum. However, the performance of Ethereum is limited. Countless smart contracts run on Ethereum and compete with each other to occupy resources. Ethereum often suffers from network congestion due to sudden explosion of individual projects, such as the CryptoKitties Incident.
Later, BM invented EOS, claiming to usher in the blockchain 3.0 era. EOS abandoned the thousands of nodes in Ethereum and only used 21 Supernodes, which indeed greatly improved the throughput of TPS. However, the current ecology of EOS is far inferior to Ethereum. The reason is that EOS has lost the core essence of the blockchain-decentralization.
For blockchain projects, without decentralization, it would be meaningless to have a high TPS. Because decentralization is the core to make blockchain differ from the traditional internet. We cannot imagine a future DEFI projects with tens of billions market value will run on EOS which has only 21 nodes. Why do we trust these 21 nodes other than banks?

Ethereum also has a more prominent problem. Ethereum has gradually formed a closed ecology. Indeed, I am very optimistic about DEFI and it is true that DEFI is the future of blockchain. But as the Ethereum develops better, will it be fair to other blockchain projects? Most people who invest in blockchain tokens, the first token they buy will likely to be Bitcoin. There are far more believers in Bitcoin than Ethereum. No matter how good the development of DEFI on Ethereum is, Bitcoin users cannot enjoy. Is it a good thing for the entire blockchain industry?
However, Gavin Wood, the former CTO of Ethereum, has long seen through all this. He left Ethereum and embarked on a brand-new journey.

Ethereum missed Polkadot, and Polkadot started a new era.

2. What exactly is Polkadot?
According to the above, we expect that the real blockchain 3.0 should meet two conditions:
  1. Under the premise of sufficient decentralization, TPS is large enough, and projects under the ecology will not compete with each other for network resources, and the entire network can grow infinitely.
  2. It can be interoperable with other blockchains, which we call "cross-chain".

Polkadot solves these two problems perfectly, and there are many excellent features, which will be slowly introduced in subsequent articles. Today, we only briefly explain what Polkadot is.

Describe Polkadot in one sentence:
Polkadot is nothing, but because it is nothing, it can be anything.

How to understand it?
If we compare a blockchain to a skyscraper:
The Bitcoin Building has been completed. This building focuses on one function, which is bookkeeping.
The Ethereum Building has been completed. This building is mainly smart contracts and smart contract-based applications. It is very difficult to add other functions or make major changes.

Polkadot is a foundation that is responsible for the safety of all the blockchain buildings built on this foundation. Before a blockchain project is built, Polkadot is nothing. After the blockchain project is built on the foundation (Polkadot), the entire building will have certain functions. Therefore, no matter what the top blockchain technology appears in the future, it can become a member of the building complex based on the Polkadot foundation.
Of course, these blockchain buildings of the Polkadot Building complex can carry out business transactions.

At the same time, Polkadot will also specialize in building various bridges to connect the Bitcoin Tower and the Ethereum Tower, so that other successfully constructed blockchain buildings can have business contacts with the Polkadot complex.

https://preview.redd.it/t6z0fh1a2ye51.png?width=845&format=png&auto=webp&s=f4c1019bb01e30f787c1afde1925fb8b0fe63c1b
Unlike the Bitcoin Tower and the Ethereum Tower, the Polkadot complex has enough capacity. When the Polkadot foundation is about to be unbearable, it will continue to replicate the foundation and continue to build the second and third Polkadot complex. It can be expanded to countless buildings, and there are still bridges for business exchanges between these newly established Polkadot buildings.

So what you say Polkadot is, it is nothing, but if there are more blockchain projects join in, it will be everything.

Difference between smart-contracts and nodes

Difference between smart-contracts and nodes
Greetings. 🤗 In this post we will tell you about the difference between a node and a smart contract.

❓ What is a node?

A node is any computer that is connected to a blockchain network. Simply put, this is the point at which messages can be created, received, or transmitted. For a bitcoin network, for example, there are full nodes, supernodes, miner nodes, and an SPV client.

❓ What is a smart contract?

Smart contracts are computer data transfer protocols that use mathematical algorithms to automatically complete a transaction after meeting established conditions and complete process control. The protocol is used to enter all the terms of the contract concluded between the parties to the transaction in the blockchain. Obligations of participants are provided in the smart contract in the form of "if-then" (for example: "if Party A transfers money, then Party B transfers the rights to the apartment"). Once these conditions are met, the smart contract independently performs the transaction and ensures that the agreement is respected.

❗️ Thus, the smart contract is the action that takes place, and the node is the place where this action takes place.

💡 The Relictum Pro innovative approach

✔️ The distinctive mechanism is as follows: only the hash of one event (transaction) is recorded in the block, and it cannot be changed. Thus, all kinds of collisions are swept aside. In addition to recording the event hash into the block, when forming a new one, the entire hash of the previous block and + integer value is taken (we put the sequential block number in front of the block). There is a main chain of blocks - Master_Chain, which contains only the hash of a block of lower and side smart contracts.

✔️ In parallel with the main Master_Chain, various independent chains are formed - these are smart contracts that organize the three-dimensional distribution, for example:
- first smart contract - generation of tokens;
- second smart contract - sale of goods through the store;
- third - a crypto exchange;
- fourth - delivery of goods, etc.

✔️ Thus, the organization of chains of smart contracts and the main Master_Chain leads to a four-dimensional model of the organization of distribution of blocks.

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.

In this article I will discuss the foundations that are being laid in preparation for the release of Overledger Network, The Network of Networks to make all of this possible and to unleash the true potential of blockchain with a secure, hyper-connected decentralised ecosystem. Table of Contents:

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

https://preview.redd.it/1wgbdybryoi41.png?width=1684&format=png&auto=webp&s=baf87b413947a19e745fcd859c0706a1cf8570b2
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.
https://preview.redd.it/veb0q18syoi41.png?width=1096&format=png&auto=webp&s=c8ea3bedd09e16e548c6da938d50f3b245e18ac6

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

Overledger Operating System

https://preview.redd.it/9v7rxtmvyoi41.png?width=1197&format=png&auto=webp&s=01c9d6e0a73f595283e3cebeb45b5a6bf484d94d
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.
https://preview.redd.it/7jqjt9v8zoi41.png?width=1127&format=png&auto=webp&s=6f40c1ae463d76c6c6b46a9e716e544e06ef3cd4
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.
