Quant (QNT) is a cryptocurrency project that was launched in June 2018 with the aim of connecting blockchains and networks globally without compromising the efficiency and interoperability of the network. It is a project that seeks to address the interoperability problem through the creation of a blockchain operating system. The project is built as an operating system for distributed ledger technology and the Overledger Network, which is designed to connect different blockchain networks. The Overledger Network is a key component of the project and is intended to serve as a platform for the connection of various blockchain networks.

Quant functions through its Overledger Network, which is designed to bridge the gap between different blockchains. Overledger enables developers to build decentralized multi-chain applications (MApps) for their customers. To build a Mapp on the network, developers are required to hold a certain amount of Quant tokens (QNT). Overledger was designed with the intention of enabling blockchain-based projects to access other blockchains. It also facilitates the interaction of an application with other applications in the same blockchain ecosystem. Quant has a structure that allows apps to interact at different levels, including transactions, messaging, filtering and ordering, and an application for sharing and referencing identical messages related to other applications.

Quant's primary use case is to provide a platform for developers to build decentralized multi-chain applications (MApps). By using Overledger, developers can write smart contracts across a wide variety of chains, including those that don’t support them, such as Bitcoin. Developers can also use the platform to create and release multi-chain applications (MApps). Additionally, the Quant App Store can read and monitor transactions across multiple ledgers, providing a comprehensive view of activities across different blockchain networks. The QNT token, which is a utility token, is utilized for accessing Quant services, particularly for Overledger users to pay their fees.

Quant was conceived by Gilbert Verdian while he was working in the healthcare sector. Verdian, who has over 20 years of industry experience in upgrading the security, technology, and business strategies of businesses globally, identified the importance of interoperability in ensuring that patients registered on different platforms are covered. Prior to Quant, Verdian served in various high-profile roles, including the chief information security officer of Vocalink, a Mastercard company, and the security lead of the Ministry of Justice, UK. The second co-founder, Dr. Paolo Tasca, is a digital economist specializing in distributed systems. Dr. Tasca has served as a special advisor on blockchain technologies for the EU Parliament, the United Nations, and numerous central banks worldwide.
