Quant Network has been in the top #100 for a month, slipping out as of recently, with just 2485 token holders. I think the project's flown beneath the radar for many!
Here's the low-down:


The CEO Gilbert Verdian founded the ISO TC307 standard for blockchain in April 2016, where 52 countries now collaborate to implement a standard that will be adopted globally. Standards are a pivotal component to adoption, as they essentially represent a commitment made by numerous entities to use a particular technology or format.
A key aim of standardisation is to ensure interoperability between multiple DLT/Blockchain implementations and, in doing so, reduce the risk of a fragmented ecosystem. Gilbert Verdian is the chairman of the SG7 workgroup on "Interoperability of blockchain and distributed ledger technology systems". Work into the standard is ongoing and it is planned to be finalised no later than 2021.

Quant Network aims to provide the technology for enterprise and startups to take advantage of DLT's, by making it possible to connect to blockchains using just 3 lines of code in less than 8 minutes. Unlike other interoperability solutions Overledger isn't a blockchain and doesn�t require fundamental system changes to use the technology. It is more apt to call it a blockchain protocol, comparable to the internet protocol TCP/IP. Overledger facilitates routing between blockchains by using a verification block, which not only helps ensure that consensus times are kept to a minimum, but also handles double spend and forking issues across different ledgers.

Overledger Architecture Model

Architecture Design (Sourced Whitepaper): https://i.redd.it/qk0ehjgafwk21.png

The team launched Overledger last November, demonstrating 4 multi-chain apps running on Bitcoin, Ethereum, Ripple and Hyperledger:

The product is at full release for the Enterprise version of Overledger for permissioned blockchains. The current open source version will be connected to permissionless blockchains by the summer, currently it's test-net only.
Overledger can facilitate cross-chain atomic swaps, and Zero Knowledge Proofs are possible using the teams patentedTrustTag solution: Trusttag allows the tokenisation of assets to be used on the blockchain and to easily connect off chain data to onchain.
Interoperability is not just limited to transferring value between blockchains via atomic swaps but messages / data can be used by adding a hash of a message to the metadata of a transaction on any blockchain which facilitates the interoperability without having to add another blockchain by utilising the trust and security of the source blockchain.

All communication is encrypted on the client side. Overledger is not affected by forks or updates of underlying blockchains, as it abstracts the messaging layer from the transaction layer, sitting above it.
Their ICO finished April last year, followed by a token burn in September as the team only raised $10-11M of their $40M ask. The ICO Price was $1.51 and pre-sale 94c. The first draft of the Token utility paper was released in January. The Treasury function will be completed by the second half of the year, so we can probably expect an updated Token utility paper between now and then.

In recent appointments, Gilbert Verdian was the Chief information security officer (CISO) at NSW Health (Australian Government), Deputy CTO at HM Treasury working with Cabinet Ministers and the Chancellor responsible for securely transforming Central Government Departments including the systems that are critical for the operating and running of the UK economy. Responsibilities covered Downing St, Cabinet Office, Bank of England, Financial Services Authority, and the Debt Management Office. He was also the CTO at UKFI, responsible for rapidly establishing the agency during the financial crisis to take ownership of �350B worth of toxic assets from the banks. As CISO for PayUK, previously NPSO – Nation Payments Scheme Operating, he was responsible for the security for all payments in the UK, �6T per year.

In the past, Gilbert worked for the Federal Reserve on their Secure Payments Task Force, founded the, Bank of England Cybersecurity committee, Australian Government, Ministry of Justice, BP, HSBC, and VocaLink (a Mastercard company).
Gilbert currently serves as the Chair of DLT for healthcare in the British Government.

Jean-Paul Dejong, Chief Architect has worked across Government in Defra, HMRC, Border Force, National Crime Agency, Ambulance Radio Programme and Europol. At UK Border Force he introduced the first interactive pre-departure checking system in Europe. He�s worked as solutions architect in the private sector at KPMG, Compaq and Citibank and PrimeLocation.

Colin Paterson has worked in working in cyber-security, for the last 16 years in large Fortune 100, FTSE 100 and Government organisations around the world: AI and penetration testing at Barclays Bank, Prudential, Nationwide, Guardian. He co-founded machine-learning, cyber-security and AI firm Trudera with Gilbert Verdian 11 years ago. He invented the TrustTag patent to solve the counterfeit problem in supply chains, it�s evolved to prevent fraud and is a key component of Overledger.

Co-founder and advisor Paolo Tasca is adviser on blockchain technologies for EU Parliament and UN, founder and advisor for UCL Centre for Blockchain Technologies and former lead economist for Deutsche Bank. Tasca recently stated that "Enabling cross-chain communications � including the recognition and transfer of transactions � is not dissimilar to opening borders to allow international trade. It will usher in a new era of digital economic growth and prosperity not unlike the industrial revolutions of the past."

The ISO/TC 307 standard is being adopted and promoted in the EU by:

Token utility

The Overledger network decouples the transaction and messaging layers of the underlying blockchain, adding support for off-chain smart-contract execution and storage.
The token protects the service from denial-of-service attacks. QNT is required and locked up as a license to access the network on both public and enterprise (permissioned) chains, is payment for read and write operations and to access multi-chain apps (mApps). Dev�s can choose to pay for QNT �gas� on behalf of the user, choosing to monetise their app through a different channel (advertising, fiat subscription etc) – allowing for seamless experiences without the need of Metamask or 3rd party extension. mApp users pay in fiat currency, and the Treasury function handles the purchasing of QNT.
Here's the first draft of the QNT Token Utility report: https://www.quant.network/QUANT_Token_Utility_V0.1.pdf

In the second half of the year the team plans to decentralise their network by allowing Enterprises and additional Cloud Service Providers, as well as the community the possibility to host an incentivised "gateway". It is still to be confirmed how gateway operators would be incentivised, the team is considering a dual utility tokenomics system.
At the time of writing, 16% of the QNT circulating supply has been registered by developers working on Overledger applications.
