Metis L2 Docs

Metis is a next-generation Layer 2 Ethereum solution, designed to empower decentralized applications and businesses with scalability, low-cost transactions, and a user-centric ecosystem. By leveraging advanced technologies like Optimistic Rollups and Decentralized Sequencers, Metis aims to overcome the limitations of traditional blockchain networks while maintaining the core ethos of decentralization and security.

Key Features of Metis

• Scalability: Supports high transaction throughput while maintaining low latency and cost.
• Ethereum Compatibility: Fully compatible with Ethereum’s EVM, making it easy for developers to deploy dApps.
• Decentralized Sequencing: Eliminates single points of failure by decentralizing the process of transaction ordering and block production.
• Community-Driven Governance: Encourages collaboration and community-led decision-making.
• Cross-Chain Interoperability: Facilitates seamless asset and data transfer between Ethereum Layer 1 and Metis Layer 2.

Structure

The entire structure of Metis Layer 2 is designed around several algorithm loops which are designated to mitigate the potential damage and filter the possible malfunctions of decentralized actors and/or other outer ill-wishers.

There are 7 distinguished actors participating in the system (Governance Protocol is a part of L1 / Smart contract, but it handles a number of functions that make it a separate entity):

1. User sends the transactions;
2. Sequencer Node is responsible for correcting the blockchain, propagating the blocks through the Peer Network;
3. Metis Blockchain is an entity held by Decentralized Sequencer;
4. Verifier is the counterpart of Sequencer, mostly responsible for keeping an eye on the Sequencer to not provide false/invalid data;
5. L1 Smart Contracts — the set of smart contracts that handle the security of the system, solve the disputes between Sequencer and Verifier;
6. Memolabs stores the transaction data;
7. The Governance Protocol is responsible for anything related to the efficiency of the system.
