What is Opera Mainnet (Fantom)?

Opera is the Asynchronous Byzantine Fault Tolerant (aBFT)-powered mainnet that makes use of the Fantom Lachesis protocol. Opera is a permissionless and open-source development framework designed specifically for the construction of decentralized applications (dApps) on the Fantom network. The Opera mainnet is made up of a wide range of smart contract capabilities that can interact with the Ethereum network due to both systems' support of the Solidity programming language and integration with the Ethereum Virtual Machine (EVM).
