The Fantom network is a smart-contract platform that allows developers to write, compile, and deploy smart contracts the same way they can on Ethereum. It runs on a directed acyclic-graph-based distributed ledger and is integrated with the Ethereum Virtual Machine (EVM) and the Web3JS stack. It uses an asynchronous Byzantine Fault-Tolerant (aBFT) Proof-of-Stake (PoS) consensus mechanism called "Lachesis."
