# v7-Theta Upgrade (Completed March 25, 2022)

  • Gaia v7.0.x
  • Cosmos SDK v0.45
    • Minimal update with small fixes
  • Gravity DEX: Liquidity v1.4.5
    • Adds a circuit breaker governance proposal type to disable adding new liquidity in order to make a migration possible.
  • IBC 3.0.0
    • Interchain Account Module
      • Allows the creation of accounts on a "Host" blockchain which are controlled by an authentication module on a "Controller" blockchain.
      • Arbitrary messages are able to be submitted from the "Controller" blockchain to the "Host" blockchain to be executed on behalf of the Interchain Account.
      • Uses ordered IBC channels, one per account.

# v8-Rho Upgrade (expected Q1 2023)

# v9-Lambda Upgrade (expected Q1 2023)

  • 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).
