ICON is an open-source South Korean blockchain-based platform focused at greater openness and interoperability. Founded by Daeki Lee and Scott Smiley, the ICON transmission mechanism easily connects different blockchains (for example, NEO and Bitcoin) and allows transactions among them. This feature allows cross-chain operations that were previously impossible without the ICON protocol. The platform can also implement smart contracts, apply DPoC protocols (Delegated Proof-of-Contribution) and adopt Delegated Proof-of-Stake algorithms. Powered by the innovative mechanism called 'loopchain', the protocol can process hundreds of operations per second.
