Description
Modify op-challenger to support the ZKDisputeGame type. The op-challenger will monitor the ZKDisputeGame created by the on-chain factory contract and verify its legitimacy. If the claim made by the game is illegal, it will initiate a challenge. At the same time, it will also respond to malicious challenges.
Rationale
The op-challenger will interact with the zk proof generation program coded in Rust and use the zk proof to perform some actions. (The part interacting with the Rust program is not yet completed and is currently mocked.)
Example
Based on the existing startup flags, this PR adds the following flags:
--zk-dispute-game: Indicates that the zk-dispute-game type is enabled on the current chain for op-challenger
--zk-challenge-by-proof: Indicates that op-challenger should initiate challenges using zk proof
--zk-response-challenge-by-proof: Indicates that op-challenger should respond to malicious challenges
--zk-response-challenge-claimants: If this flag is set, op-challenger will only respond to malicious challenges for the address specified by the flag.
When enabling
--zk-dispute-game, you should also set--trace-type=zkto ensure the program runs correctly.Changes
