Fantom is developing a smart contract platform based on a directed acyclic graph (DAG). They hope to address the scalability issues of current decentralized platforms. Instead of a blockchain, Fantom's Lachesis Protocol uses a directed acyclic graph to confirm transactions asynchronously. This transaction history is immutable and cannot be modified. The platform's Opera Chain will consist of three layers: an application Layer, Opera Ware Layer, and Opera Core Layer. Fanotm issued an Ethereum-based token in 2018.
