Essential is a blockchain startup developing an intent-centric Ethereum Layer 2 network as an Optimistic rollup. Unlike traditional blockchains that rely on a transaction-based model, Essential uses an intent-based model where users specify desired outcomes rather than exact instructions. As a Layer 2 solution, Essential processes user intents off-chain using "specialized solvers," making the process more efficient. This approach aims to improve user experience, reduce on-chain workload, and enhance scalability.
