Summary

Through accepting this proposal it is proposed to unfreeze the expired IBC Tendermint client
07-tendermint-620 which interconnects the Cosmos SDK blockchains cosmoshub-4 and evmos_9001-2

Details

Due to a recent vulnerability discovered in Etheremint, the EVMOS network was down for several days, causing several IBC clients to expire.
We need to reactivate the connection so that users can recover their ATOM tokens locked in the IBC channel.

Here are the details of the expired client and the new one, which is kept active and updated daily.

chain_id: comoshub-4
subject_client_id: 07-tendermint-620[state] [status]
substitute_client_id: 07-tendermint-1470 [state] [status]

Governance votes

The following items summarize the voting options and what it means for this proposal:

YES - The canonical Tendermint client 07-tendermint-620, which interconnects evmos_9001-2
and cosmoshub-4 will get updated with the state of another active Tendermint client (07-tendermint-1470).
NO - The Tendermint client 07-tendermint-620 remains expired/frozen.
NO WITH VETO - A ‘NoWithVeto’ vote indicates a proposal either (1) is deemed to be spam, i.e., irrelevant to Cosmos Hub, (2) disproportionately infringes on minority interests, or (3) violates or encourages violation of the rules of engagement as currently set out by Cosmos Hub governance. If the number of ‘NoWithVeto’ votes is greater than a third of total votes, the proposal is rejected and the deposits are burned.
ABSTAIN - You wish to contribute to quorum but you formally decline to vote either for or against the proposal.
