ICS 功能
部分集合安全（Partial Set Security） 和 权重塑形（Power Shaping） 为消费者链和验证者双方都带来了收益：Top-N 消费者链
投票权重位于前 N% 的验证者必须参与该消费者链的验证。 e.g.top-95 表示按投票权重计算，覆盖前 95% 权重的验证者必须运行该消费者链二进制。
选择加入型消费者链
只有选择运行某条消费者链的验证者，才需要运行该链二进制，并有资格参与消费者链奖励分配。参数自定义
消费者链可以按自身需求自定义验证者集合：- 定义允许列表/拒绝列表
- 设置验证者最大数量
- 设置验证者权重上限
值得关注的消费者链
当前 Cosmos Hub 有以下两条消费者链。Neutron
Neutron 是一个智能合约平台，也是首条接入的消费者链。Neutron 于 2023 年 5 月接入为消费者链，更多细节可参见 Hub 的 792 号提案。
Stride
Stride 是一个流动性质押服务提供方，旨在为 Cosmos Hub 代币持有者释放流动性。Stride 于 2023 年 7 月接入为消费者链，更多细节可参见 Hub 的 799 号提案。
资源
如需了解更多信息，请访问：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
Currently the Cosmos Hub has the following two Consumer Chains.Neutron
Neutron, is a smart contracting platform, that was the first consumer chain onboarded.Neutron was onboarded as a consumer chain in May 2023, see Hub proposal 792 for more details.
Stride
Stride, is a liquid staking provider, which aims to unlock liquidity for Cosmos Hub token holders.Stride was onboarded as a consumer chain in July 2023, see Hub proposal 799 for more details.
