QI is an open-source platform for launching decentralised applications and enterprise blockchain deployments in one interoperable, highly scalable ecosystem. QI Blockchain is the first decentralised smart contracts platform built for the scale of global finance, with near-instant transaction finality. Ethereum developers can quickly build on the QI blockchain as Solidity works out of the box.
QI is a fast, scalable, and secure layer-1 platform built on the POW consensus protocol.
QI utilises Hyperledger Besu as its base architecture. Java-based Hyperledger Besu is an open-source Ethereum client created under the Apache 2.0 licence.
