What Are the Risks of Using Off-Chain Voting Mechanisms for On-Chain Execution?
Off-chain voting is cheaper and faster, but the main risk is the "execution bridge" – the mechanism that translates the off-chain vote result into an on-chain action. This bridge can be a single point of failure if it is controlled by a small set of trusted entities or a multisig wallet.
A compromise of this bridge allows an attacker to execute malicious actions on-chain despite an honest off-chain vote.
