Metis, an Ethereum Layer 2 network focused on scalable and low-cost smart contracts, published its 2023 technical roadmap outlining a series of upgrades aimed at increasing decentralization, security, and cost-efficiency for its Andromeda mainnet. The roadmap centers on adopting Optimism’s Bedrock architecture, which is designed to further reduce transaction fees while maintaining EVM equivalence and Ethereum-level security. Bedrock also lays the foundation for more modular, efficient infrastructure, positioning Metis to evolve its rollup design over time. A second major theme in the 2023 roadmap is a push toward full rollup maturity via fraud proofs and sequencer decentralization. Metis plans to integrate the Cannon fraud-proof system, moving from Vitalik Buterin’s Stage 0 rollup classification toward Stage 1, and ultimately to a fully functional rollup once a decentralized sequencer pool is implemented. This sequencer design is notable because Metis intends to share sequencer revenue with the community, and to harden the network’s liveness and censorship resistance by preventing any single operator from controlling transaction ordering. In parallel, Metis outlines work on a Hybrid Rollup architecture that combines optimistic rollup scalability with zero-knowledge proof security, using zkMIPS and STARK-based provers/verifiers generated by Cannon to enable faster finality and stronger guarantees at somewhat higher costs. Together, these 2023 initiatives are framed as the technical groundwork for a more decentralized, secure, and capital-efficient Layer 2 environment to support a broader Web3 economy on Metis Andromeda.
