Module: Circuit Breaker

[tac0turtle]

Summary

Currently in the Cosmos, if there is a vulnerability the chain has to halt and wait to figure out how to fix things. This downtime could be costly and prevent many applications living on the chain from conducting business.

In order to prevent downtime, Cosmos SDK should provide a way to stop certain messages from being executed. In light of recent events the goal is to get this feature out asap and the iterate on it.

Problem Definition

Vulnerabilities force a chain to stop until the bug is fixed and able to come back online.

Proposal

Create a module, for now, that can be imported into chains that could prevent certain messages from being executed.

A simple module that has a list of messages that are prevented with a list of address that are allowed to block transactions could be the first iteration.
