+---
+
+# Interchain Security
+
+The Interchain Security feature, brings to the Cosmos Hub a shared security model, where the Cosmos Hub validators, also validate on 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.
+
+Currently the Cosmos Hub has the following two Consumer Chains.
+
+## Neutron
+
+[Neutron](https://neutron.org/), 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](https://www.mintscan.io/cosmos/proposals/792) for more details.
+
+## Stride
+
+[Stride](https://www.stride.zone/), 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](https://www.mintscan.io/cosmos/proposals/799) for more details.
