GnosisChain - Invalidate EthPoW Bridge Validators

invalidate-bridge-validators-process.md

Intro

Goal of the following procedure is the creation of a transaction on the Governance Multisig on EthereumPoW that can trigger an update on the Bridge Validators contract, on both the Native Bridge and the AMB:

• Native Bridge Validator contract: 0xe1579dEbdD2DF16Ebdb9db8694391fa74EeA201E
• AMB Validator contract: 0xed84a648b3c51432ad0fD1C2cD2C45677E9d4064

The transaction will execute transferOwnership("0x5e4ec802dceec72733717e43ce681425a5014e65") and replace the current owner of the contract, which is the Governance Multisig, to 0x5e4ec802dceec72733717e43ce681425a5014e65 as the new owner.

As a proof that we own that account we sent 0.0001 ETHW to the Governance Multisig on EthPoW: see https://www.oklink.com/en/ethw/tx/0x6aa09f7def7ba657332c2c3d3c1511bc630f08880cfbf431a1942a6f3206dd08.

On-Chain Confirmations

Send a transaction to the Governance Multisig to approve the Safe Transaction Hash:

Where data is approveHash("0x7ff17a40bb3451d75b7dde05da59f8ab5b81f177a21d56dd11ce18d588b03977"), see decoded data at this link.

Further steps

Once we execute the transaction, the new owner will remove the current validators from the Bridge Validators contract and set the ownership of the Contract back to the Governance Multisig.
