||
- Gaia v8.0.x | ||
- Cosmos SDK v0.45.12 | ||
- Version bump with a number of fixes | ||
- See [changelog](https://github.com/cosmos/cosmos-sdk/blob/v0.45.12/CHANGELOG.md) for details | ||

|
||
- Gaia v9.0.x | ||
- Cosmos SDK v0.45 | ||
- IBC 4.2 | ||
- Interchain Security - Replicated Security | ||
- The Cosmos solution to shared security that uses IBC Cross Chain Validation (CCV) to relay validator set composition from a Provider Chain (Cosmos Hub) to a Consumer Chain. This validator set is in charge of producing blocks on both networks using separate nodes. Misbehavior on the Consumer Chain results in slashing Provider Chain staking tokens (ATOM). | ||
