The Quant Network project encompasses the Overledger blockchain operating system, responsible for interoperability between blockchains and establishing more flexible connections between global networks and chains, along with the QNT token.
In 2015, technology expert Gilbert Verdian, with a background in e-business and strategic management, Paolo Tasca with a doctorate in business, and Colin Paterson working in the field of energy sciences founded the Quant ecosystem. The ICO for the company where the Quant idea was developed was carried out in May 2018.
The foundation of the project is the Quant Network, an ecosystem for blockchains operating through the Overledger platform. Overledger facilitates the creation of decentralized applications (dApps) on the blockchain. The Overledger platform can utilize the advantages of multiple blockchains instead of a single, capacity-limited blockchain.
Quant Network (QNT) was launched in June 2018 with the goal of connecting blockchains and networks globally without reducing the network's efficiency and interoperability. It is known as the first project to solve the interoperability issue through the creation of a blockchain operating system.
The Quant Network (QNT) project is built as an operating system for connecting different blockchain networks through distributed ledger technology and the Overledger network. It is referred to as the first operating system to be constructed for blockchains.
The primary goal of Quant Network (QNT) using Overledger is to fill the gap between different blockchains. The backbone of the project is the Overledger network, referred to as the ecosystem on which the future digital economy ecosystem will be built.
Overledger allows developers to create decentralized multi-chain applications (known as mApps) for their clients. Developers need to own a certain amount of Quant Network tokens (QNT) to create an mApp on the network.
The heart of the Quant Network project is the technology of Quant Network, which automates trust functions between multiple blockchains with the help of the Overledger operating system. The system is specified as the first operating system built to connect blockchains and networks in sectors like financial services, healthcare, and others, without creating obstacles to interoperability.
Overledger represents the core around which a future digital economy ecosystem, enabling developers and businesses to create decentralized multi-chain applications, needs to be built. Additionally, being a part of Overledger will be secured by using QUANT (QNT) tokens, which are used for platform usage fees or annual licenses.

The removal of communication barriers between blockchains and the support for mApps to operate as dApps on several different ledgers led the Overledger team to design an architecture that supports both interoperability and scalability. This architecture is inspired by the TCP/IP models used in communication networks. Developers have decided that organizing according to layers performing individual tasks is the best way to achieve the platform's goals, described as follows.

The transaction layer manages the storage of transactions using ledger technology. It hosts all operations required to reach consensus across several blockchain domains. This process is facilitated by placing all related transactions in a single layer, but the scope of transactions made in a specific blockchain is limited to that domain and cannot be made valid in other ledgers. Therefore, this layer consists of various and isolated ledgers.

The messaging layer, also considered a logical layer, deals with all information from ledgers deemed relevant. This includes smart contract data, metadata, and transaction data. In terms of metadata, the added strings usually represent a summary of off-chain messages that could be interpreted as payload. This layer is also used for storing all transaction information and summaries for messaging between multiple applications.

The Filtering and Ordering layer processes messages consisting of extracted transaction information. Messages referenced in a transaction through an off-chain hash exchange are subjected to sorting and filtering. This layer is responsible for establishing links between messages stemming from the Messaging Layer. It also verifies off-chain messages for metadata. The verification engine checks application requirements identifiable in transaction data. For example, an application can be set to accept only transactions containing a specific address, or payments might be required in the transferred tokens. Depending on the filtering done in this layer, applications may only consider messages involving the transfer of a predefined amount of tokens to a specific address.

In the application layer, messages deemed valid based on their format and signature can update their respective application states. Various applications can share the same messages or refer to messages related to other applications. These references use unique hash pointers referencing the type of transaction details with message summaries. Pointers refer to the storage location of a specific cryptographic hash. They also function as identifiers that can select a transaction from the database and verify its unchanged state.

The idea for creating Quant Network came to its CEO and founder Gilbert Verdian while working in the healthcare sector. At that time, Verdian identified the key role of interoperability in providing coverage for patients registered across various networks and multiple data sets.
Before Quant Network, Verdian served as the Chief Information Security Officer (CISO) for Vocalink, a Mastercard company, the Chief Information Officer for NSW Ambulance, CISO for eHealth NSW, and the security leader for the UK Ministry of Justice.
The second co-founder, Dr. Paolo Tasca, is an entrepreneur specialized in distributed systems and a digital economist. Dr. Tasca has served as a special advisor on blockchain technologies for the European Parliament, the United Nations, and numerous central banks worldwide. He is also a co-author of several books on fintech and the founding partner and chairman of the board for the Retail Blockchain Consortium.
The Quant Network team aims for excellence to ensure blockchain technology is used most effectively.

The Quant Network (QNT) team works in an interconnected manner economically, socially, culturally, and environmentally.
The network uses Distributed Ledger Technology (DLT) but the simplicity and potential lack of interoperability, along with the inability to integrate with different generation systems, prevent the technology from realizing its true potential. Nowadays, DLTs find applications in almost every industry for various applications. This also reflects the evolutionary processes of the technology. The emerging problem is developers using DLT or blockchain solutions for their own interests, as these approaches can harm such projects.
In contrast, the Quant platform is standard and protocol-independent, simplifying the work and connecting the system to any network, any DLT worldwide. It helps to share and exchange information and value securely and cost-effectively.
Furthermore, Quant Network (QNT)'s solutions allow the best use of any DLT with easy implementation, focused innovation, and reliable support.

Led by Verdian, the team began solving a series of problems to unveil a concept referred to as the "Internet of Trust":

An important structure of the Quant ecosystem is the Quant treasury. The treasury enables businesses to make payments in fiat for licenses to purchase QNT tokens directly from public exchanges. The purchased QNTs will be locked in the treasury for the duration of the license and re-locked if renewed. QNTs help to limit supply and create buying pressure as the Quant Network ecosystem grows.

Initially demonstrating the ability to read and monitor transactions on multiple ledgers including Bitcoin, Ethereum, and Ripple, the Quant Network has promised to add support for more as the platform evolves. The same system supporting mApps should allow the Quant Network team to start working on the Quant Network App Store as one of the various revenue streams within the ecosystem.
The App Store is expected to provide the following functionalities:

In addition to the Quant Netwrok App Store, Quant also plans to launch its Software-As-A-Service (SaaS) for enterprise and middleware software applications. These will offer solutions tailored according to the needs of individual sectors based on the demands of various industries. Thus, developers promise to focus on sectors like healthcare, supply chain, government, and financial services. One of these products is known as Quant Health, used by healthcare institutions to keep their systems operational with the help of blockchain.

The Quant Network (QNT) team aims to create business applications that allow their users to benefit from the decentralized structure of the Quant platform and the potential to facilitate operations across multiple chains. While use cases are still under development, some areas that may be of interest include:

In addition to these products, the Quant Network team continues to work on a licensing plan for its core technology to be offered to various internet and blockchain providers and manufacturers.

QNT tokens are primarily used for digital access to a specific service or application (mApp) that is part of the Quant Network platform. Access to these services and applications is provided to both users and developers.
In addition to the token quantity, the access fee will also be based on a fixed amount of fiat currency. For example, consumption fees of 10 US Dollars per month for developers and businesses will require payment based on the equivalent price in QNT tokens to the Quant Treasury.
With an increase in the number of users and the consequent change in QNT demand, the total number of tokens required for access to the platform and applications can vary based on the value of the tokens and their circulating supply (as of March 2019, these figures had surpassed 9 million of the total 14.6 million in supply). Pegging the value of access fees to fiat values should allow developers to hold QNT in more flexible amounts, as the price can vary relative to fiat currency. As of March 2019, the market value of Quant Network (QNT) was at the level of 34 million US dollars.

The Quant Network ecosystem uses the QNT token to access the network and the Overledger platform and secures data sharing. As a significant part of the network, the QNT token shares and supports the project values stated by the team members:

Considering these approaches, it's hard not to want to learn more about the project and its tokens.

Since the introduction of blockchain and distributed ledger technology, innovators have found use cases in almost every known sector, but a seamless interoperability issue emerged among these projects. Quant Network (QNT) was created as the missing link between "different" blockchains.
Quant Network (QNT)'s operating system, Overledger, is designed to serve as a gateway for any blockchain-based project to access all other blockchains. Overledger also works to connect an application to other applications within the same blockchain ecosystem, like Ethereum.
Quant Network (QNT) creates different layers for applications to interact on different levels beyond multi-blockchain interactions. Quant Network has an application that owns different layers for transactions, messaging, filtering and sorting, and sharing and referring to the same messages related to other applications.
The Quant App Store has the ability to read and monitor transactions across multiple ledgers. Using Overledger, developers write smart contracts on a wide range of chains, including those not supported by the application, like Bitcoin.

The Overledger system forms the backbone of the Quant Network. Overledger facilitates communication across DLT networks and interacts with different blockchains. Including gateways to connect different blockchains, similar to Ethereum's proof of stake blockchains, the Quant Network team is involved in handling treasury smart contracts. The team manages QNT payments flowing from users to gateways in a way that holds any observer accountable.

There is no need to purchase QNT tokens to use the Quant Network, but QNT tokens are required to use the network.
Any developer needs to purchase a license to create something on the platform, which requires locking the tokens for 12 months. The cost of running Gateways and performing read or write operations on Overledger requires the use of QNT tokens.
The maximum supply of QNT tokens is set at 14,612,493 tokens. The distribution of QNT tokens is as follows:

An additional 2 million tokens are held by the company. These tokens are unlocked and can be sold or given away at any time.

As of the date this article was written, the live QNT price is $368.70 with a 24-hour trading volume of $135,197,737. QNT has dropped 1.40% in the last 24 hours from the time this article was written. The ranking of QNT on the exchange from which current data was taken is 41st, with a live market value of $4,451,171,252. It has a circulating supply of 12,072,738 QNT coins and a maximum supply of 14,612,493 QNT tokens.
