Quant is a London-based blockchain technology company that aims to achieve universal interoperability between blockchains through its Overledger OS, a blockchain operating system, with the goal of connecting blockchains and networks on a global scale without reducing the network's efficiency and interoperability.Overledger, the company's core product, is an API gateway that abstracts permissioned and permissionless blockchains into a unified interface. The Overledger Network is a community network that serves as a home for distant connector gateways that process Overledger transactions.The protocol's native utility token, QNT, can be used to pay for network resources, staking, and license fees. In 2018, the project successfully completed a public sale round, in which 9.9 million QNT has been sold.
