Cosmos
The stack to build your own sovereign, interoperable-by-default blockchain.
Cosmos is an ecosystem of frameworks (Cosmos SDK, the CometBFT/Tendermint BFT consensus engine) for building application-specific blockchains (app-chains) instead of a single smart contract on a shared chain. The IBC protocol links those chains to exchange tokens and data with cryptographic verification. Choose it when you need a dedicated, sovereign, fully customizable chain without the congestion and fees of a mutualized one.
What Cosmos brings to your project.
Typical use cases: Launch a dedicated app-chain (DeFi, gaming, RWA), interoperable via IBC.
- 01
Modular Cosmos SDK: purpose-built app-chain in Go.
- 02
CometBFT (Tendermint) BFT consensus with instant finality.
- 03
IBC: native interoperability across the ecosystem's chains.
- 04
Full sovereignty: own governance, validators and tokenomics.
