The FANTOM cryptocurrency is an advanced blockchain platform that employs a novel consensus mechanism known as the Lachesis protocol to address critical issues in distributed ledger technologies, such as transaction speed and scalability. Introduced by a collaborative effort at the FANTOM Foundation and researchers at Yonsei University, FANTOM aims to facilitate near-instantaneous transactions and support complex smart contract interactions. Its OPERA chain, a Directed Acyclic Graph (DAG) structure, forms the backbone of FANTOM's ecosystem, offering improved performance over traditional blockchains. The Lachesis protocol ensures that the FANTOM network achieves asynchronous Byzantine Fault Tolerance (aBFT), providing security against malicious activities without compromising on high throughput.
