# Radix vs Cosmos

<Infobox>
| **Radix** | Single sharded ledger, atomic composability |
| **[Cosmos](https://cosmos.network)** | Sovereign app-chains, [IBC](https://ibcprotocol.dev) message passing |
| **Key Difference** | Atomic cross-shard vs async cross-chain |
</Infobox>

## Overview

Radix and [Cosmos](https://cosmos.network) take fundamentally different approaches to scalability:

### Architecture

**Cosmos** uses sovereign app-chains connected via Inter-Blockchain Communication ([IBC](https://ibcprotocol.dev)). Each chain runs its own consensus and maintains its own state. Cross-chain operations are asynchronous messages — there's no atomic composability between chains.

**Radix** uses a single sharded ledger with [Cerberus](/contents/tech/core-protocols/cerberus-consensus-protocol) braiding consensus across shards. Cross-shard transactions are [atomic](/contents/tech/core-concepts/atomic-composability) — they either fully succeed or fully fail, enabling [DeFi](https://en.wikipedia.org/wiki/Decentralized_finance) composability that's impossible in the Cosmos model.

### Trade-offs

Cosmos offers more app-chain sovereignty and customization. Radix offers stronger composability guarantees and a unified DeFi ecosystem. For DeFi specifically, Radix's atomic cross-shard model is more suitable — DeFi protocols need to compose with each other in single transactions.
