The Cosmoshub V9 Lambda upgrade proposal has been put on the chain. After the upgrade, inter-chain security (now called Replicated Security) will be implemented.

The consumption chain will be able to use the security of the Cosmos hub to improve its own security. It is expected that more and more protocols will add replication security, and these consumer chains will work closely together in the "ATOM Economic Zone" and empower $ATOM

Recommended to vote.
