Mitosis Chain

Mitosis Chain is a Layer 1 blockchain that combines the best of Ethereum’s execution capabilities with the Cosmos ecosystem’s consensus mechanisms. One of our primary objectives has been to support the EVM while harnessing the benefits of CometBFT. We’ve aimed to develop an approach that is EVM-compatible, high-performing, and easy to maintain.

We were inspired by Ethereum’s modular architecture:

  • The execution client is responsible for transaction handling, transaction gossiping, state management, and supporting the EVM
  • The consensus client handles block building, block gossiping, and consensus logic

​
Modular Architecture

The Mitosis Chain employs a modular architecture that separates execution from consensus:

Execution Layer

Provides completely EVM-compatible execution environment by leveraging unmodified Ethereum execution clients

Consensus Layer

Built upon the Cosmos SDK and utilizes CometBFT for consensus

​
Key Features

  • EVM Compatibility: Achieves complete EVM compatibility by leveraging unmodified Ethereum execution clients
  • Client Diversity: Leverages the same level of execution client diversity and innovations as Ethereum from day one
  • Communication: The two layers communicate using Engine API, with the consensus layer utilizing Octane
  • Consensus Benefits: Leverages CometBFT and Cosmos SDK advantages including instant finality, fast block times, and Byzantine fault tolerance

​
Design Benefits

The Mitosis Chain’s modular architecture provides several advantages:

  1. Simplified Consensus Layer: Most logic exists as contracts on the execution layer, while the consensus layer is kept thin
  2. Future-Proof: Easily follows Ethereum’s technological advancements for the EVM
  3. Flexibility: Easier to adopt new frameworks or architectures for consensus being researched in the industry
  4. Innovation: Can quickly benefit from improvements in both Ethereum execution and Cosmos consensus
