Cosmos Hub launched Replicated Security in an attempt to take center stage in the Cosmos ecosystem. This mechanism will allow other blockchains to abandon their own validators and switch to the security and set of Cosmos Hub validators. The new product should provide more security options for smaller blockchains in the Cosmos ecosystem and expand the reach of the Cosmos Hub.
In order for the blockchain to participate in Replicated Security, the team behind it will need to go through a governance process in the Cosmos Hub. This will allow validators to decide en masse which blockchains they are willing to support. When this happens, the stake hosted on the Cosmos Hub will be used to secure transactions made on other networks using the system. This means that Cosmos Hub validators will need to run validators for other networks. If a validator is not eligible, their stake in Cosmos Hub may be reduced.
Such validators can use the ATOM they hosted on the Cosmos Hub and earn additional rewards from blockchains. These rewards will be paid either in ATOM or native blockchain token. Validators will have to decide if the rewards are worth the cost of running additional validators on other blockchains.
