Fantom is a high-performance, scalable, EVM-compatible, and secure smart-contract platform.Fantom’s mainnet deployment—Fantom Opera—is built on Fantom’s consensus mechanism, Lachesis. Fantom is a leaderless, asynchronous, and byzantine fault-tolerant Layer 1 blockchain protocol.Lachesis enables Fantom to deliver fast transaction speeds, low transaction costs, and deterministic finality. This is achieved while remaining permissionless, decentralized, and open-source.
Fantom also offers exceptionally high levels of security by using a leaderless Proof-of-Stake protocol to secure the network. Unlike other solutions, Fantom does not sacrifice security and decentralization in favor of scalability.
