Fantom operates as a directed acyclic graph (DAG) smart contract platform, offering decentralized finance (DeFi) services through its proprietary consensus algorithm. Aligned with its native token FTM, Fantom seeks to address issues associated with smart contract platforms, notably transaction speed, which developers claim to have reduced to under two seconds. Established in 2018, the Fantom Foundation oversees the Fantom ecosystem, with the launch of OPERA, its mainnet, occurring in December 2019. As an open-source decentralized smart contract platform, Fantom serves as an alternative to Ethereum, aiming to overcome the limitations of prior-generation blockchains while balancing scalability, security, and decentralization. The project streamlines DApp integration and features a comprehensive staking reward system and integrated DeFi tools. Functioning as a Layer-1 blockchain, Fantom employs a custom-built consensus mechanism, Lachesis, to facilitate DeFi services via smart contracts. Lachesis ensures network security and transaction speed, with Opera serving as the mainnet deployment platform for DApps. Leveraging EVM integration and support for Solidity, Fantom enables seamless interaction with Ethereum platforms while offering transaction efficiency. The Lachesis protocol, powered by an aBFT consensus engine and DAG algorithm, ensures asynchronous, leaderless, Byzantine fault-tolerant, and near-instant finality. Meanwhile, Opera adopts a PoS model with leaderless validators to enhance network security. Beyond its role as a fast, secure, and cost-effective payment platform, Fantom incorporates on-chain governance, allowing users to vote with FTM tokens. FTM serves as the native utility PoS token, facilitating payments, network fees, staking, and governance, thereby forming the foundation of the ecosystem and enabling user rewards.
