Fantom
Web3 / blockchain technology
Fantom is a high-performance blockchain platform utilizing a Directed Acyclic Graph (DAG) consensus mechanism called Lachesis, which enables it to process transactions in parallel rather than sequentially. This architectural choice allows Fantom to achieve high throughput—processing thousands of transactions per second—while maintaining low latency and finality in under two seconds. Unlike traditional blockchains that require each block to reference the previous one in a linear chain, Fantom's DAG structure allows validators to create blocks independently and reference multiple previous transactions, creating a more efficient consensus topology. The platform is Ethereum-compatible, allowing developers to deploy existing smart contracts with minimal modification. Example: SpiritSwap, a major decentralized exchange on Fantom, leverages the platform's high speed and low costs to provide users with fast, inexpensive token swaps and yield farming opportunities. Why it matters for blockchain technology: Fantom's DAG-based approach demonstrates an alternative consensus topology that achieves scalability without sacrificing decentralization or security, proving that the linear blockchain model isn't the only viable approach for distributed ledgers.
