Metis is a Layer-2 blockchain solution that employs optimistic roll-up technology. Its roll-up solution allows developers to run applications, process transactions, and store data on a layer above Layer-1 blockchains such as Ethereum. Metis' optimistic roll-up solution maintains the security of underlying blockchain layers such as Ethereum. Metis reports to provide a more scalable and cost-effective environment for building and interacting with Web3 applications by offloading data and execution to a second layer. Metis' architecture includes an EVM-compatible virtual machine that enables developers to build contracts similar to Ethereum's.
On March 2, 2023, MetisDAO declared its ongoing construction of a Hybrid Rollup, a combination of optimistic rollup architecture with zero-knowledge proofs. With work continuing on the rollup, MetisDAO anticipates that the merged architectures would offer a secure, developer-oriented Layer 2 platform for Ethereum developers intending to deploy a variety of decentralized applications.
