How it works
The stack is modular. Leverage pre-built components or integrate custom features for your specific use case, from consensus mechanisms to governance and compliance.
Fast and Reliable
Performant, customizable, and EVM-compatible, the Cosmos stack offers engineers full control of their blockchain infrastructure and implementation. Its stable and secure codebase enables blockchains to achieve up to 10,000 transactions per second.
