What Happened on Feb. 22nd | Cosmos Hub Interchain Security and the first two Consumer Chains

The Cosmos Hub team changed the name of Interchain Security. In the past, it has been referred to as Interchain Security v1, or ICS, but going forward the team will refer to it as Replicated Security.

Replicated Security is a new feature that enables the Cosmos Hub to offer its strong security to other blockchains, also known as 'consumer chains'. With this feature, consumer chains can benefit from the Cosmos Hub's security without having to maintain their own validator sets. The cost to censor or control a consumer chain with an economic attack is the same as the cost to censor or control the Cosmos Hub itself.

The Cosmos Hub's validators can validate multiple chains at once with the same stake. In exchange for this service, consumer chains are expected to send a portion of their fees and inflation to the Cosmos Hub validators and delegators, which will then be included as part of the Cosmos Hub's staking rewards.

Neutron Chain, a Permissionless CosmWasm Platform will be the first chain to use Cosmos Hub's security.

And Noble, an asset issuance chain, possibly the chain on which $USDC will be issued. It's the second consumer chain that will use Cosmos Hub's Interchain Security, as revealed by Cosmos KOL.
