Interchain Security
The Interchain Security feature brings to the Cosmos Hub a shared security model, where the Cosmos Hub validators, also validate consumer chains. This is valuable for consumer chains, as consumer chains can focus on product-market fit, rather than business and operational agreements in bringing together a validator set. As part of this agreement, consumer chains pay for the security by distributing a portion of the consumer chain revenue to Hub token holders.
All potential chains are onboarded as consumer chains, via Hub Governance, with the feedback from the Hub community.
ICS features
Partial Set Security and Power Shaping bring benefits for both the consumer chains and validators:
Top-N consumer chains
Validators inside the top-N percent of voting power are required to validate the consumer chain.
e.g. top-95 means that the 95% of the validators (by voting power) are required to run the consumer chain binary
Opt-in consumer chains
Only validators that opt to running a consumer chains are required to run the chain binary and become eligible for consumer chain rewards distribution.
Parameter customization
Consumer chains gain the ability to customize the validator set to their needs:
- define allow/denylists
- set maximum number of validators
- set validator power cap
Notable consumer chains
