IBC Protocol
IBC enables trustless communication between Cosmos SDK chains. Understanding its security model is crucial for cross-chain application developers.
Security Model
- Light client verification
- Relayer trust assumptions
- Timeout and acknowledgment handling
- Channel ordering guarantees
IBC's security relies on the security of both the source and destination chains. A compromised chain can affect all connected chains.
Chain Security
IBC security depends on connected chains
Timeout Handling
Always handle packet timeouts properly
Relayer Independence
Don't trust relayer for security
