Fluent, a zk-rollup Layer 2 project, is advancing blockchain composability by allowing different virtual machines (VMs) from various chains to function together on a single chain. According to NS3.AI, this method, known as 'Blended Execution,' seeks to address interoperability issues between ecosystems like Ethereum and Solana, which utilize different VMs. Fluent is also dedicated to developing practical on-chain user environments, backed by initiatives such as a reputation aggregator and an ecosystem accelerator.
