A ZK bridge or other oracle could eliminate the “Push Vote Weight” step, because then Sapphire would just know how many VOTE tokens you have on BSC Testnet(the one used in the demo). There are bridges that use ZK proofs to authenticate messages to other chains, and multichain launched one. Professor Dawn Song’s research group also created one and OPL uses the bridge as an api, so it benefits from the stronger security properties of ZK immediately.
