Partial Set Security Limitation

We know that Cosmos hub is all about sovereignty!!

Previously it was like this - if Cosmos hub would have gone down, other chains would not have had any problem continuing operating and processing value. But once we implement ICS 2.0, and Cosmos hub validators share their security to up and coming chains on Forge, would not that undermine the idea of sovereignty? Meaning, if Cosmos hub halts or goes down, what happens to Consumer Chains since they are all secured by same validator set

All the communications about the active set changes are done via relayers, so if Hub goes down, consumer chains would be stuck on the same validator set that was received from the Hub. Other than not having a validator set updating, it should be fine.

(If somebody has more technical knowledge on ICS internals, please correct me if I am wrong, but the approach should be this one.)

On behalf of the PRO Delegators ’ team, I’d like to offer the validators’ perspective on this matter, ensuring we address your questions with precision. Think of a blockchain as a “container” that runs a binary, essentially the code the chain operates on. Each validator maintains independent containers for every chain they validate . Some chains might even use multiple containers, operating side-car protocols like Slinky . This compartmentalization is at the heart of the Cosmos app-chain thesis. Everything within these “containers” is modular and interoperable with other containers, but they function independently. If one container experiences downtime—due to technical or software reasons—others continue operating unaffected. In the event of hardware failure, most validators have backup servers ready to deploy at other data centers. High-quality operators often rely on “bare metal” servers, meaning the hardware is dedicated solely to them, offering full control over management and reducing operational risks. Managing these resources falls under the responsibility of sysOps within the validator workforce, ensuring smooth operations, even when chain activity spikes. Regarding…

You guys are aqesome, i love your insights and work!

As i understood its the IBC transfer from CC’s that get affected. Thank you

Re-read this comment, made more sense now. Once again, thank you for this input
