The Cosmos Stack is the most widely-adopted and battle-tested Layer 1 blockchain technology stack, in production with 200+ chains today. It is performant, customizable, and EVM-compatible, offering engineers full end-to-end control of their blockchain infrastructure and implementation.
The Stack is modular by design; use pre-built code modules or integrate custom features and logic for your use case, compliance needs, governance, consensus, and performance requirements. The Cosmos Stack is open-source.
The Cosmos Stack's primary components include:
- CometBFT, a low-latency, fast finality, and high throughput consensus engine
- Cosmos SDK, a modular SDK for building secure, high-performance, application-specific blockchains
- Cosmos EVM, a production-ready EVM layer with full compatibility with Ethereum smart contracts and tooling
- Inter-Blockchain Communication Protocol (IBC), the secure, industry-standard blockchain messaging protocol that enables cross-chain communication without the use of a third-party intermediary.
