What happened?
New cheating relayer appears. It was unprofitable to cheat after my proposal 37 when torn price was more than $3, but now with price $1.3 relayer can spend less than $3000 to start cheating with 2000 torn. My proposal 41 created to fix this possibility but it is yet not executed
Cheater transaction: https://etherscan.io/tx/0x6c5bd2fe601e43a1ae077e25bad02e2c2d844d0dc7e4d0ea04fe1f4e12f878c9
Why it is cheat: withdrawal through fake router contract without paying handling fee to stakers
Cheater: https://etherscan.io/address/0xaaaaaaaaecbb6b330e6345ec36e8d4cd498d2c2a
Proposal goals
We should respond to this challenge immediately and create strong evidence that cheating is not allowed in Tornado. Cheater should be unregistered with balance expropriation as soon as possible
Proposal code: https://git.tornado.ws/ButterflyEffect/proposal-42/src/branch/main/contracts/Proposal.sol
Proposal tests: https://git.tornado.ws/ButterflyEffect/proposal-42/src/branch/main/test/Proposal.js
Proposal contract: https://etherscan.io/address/0x8b7F82Ba0a7711C62131d4f55649D38c26d57afe#code
Results: cheating relayer balance will be nullified and withdrawed to governance, relayer will be unregistered. Also i as developer will receive 50 torn as gas compensation for deployment, proposing and execution
Operator discussion
Warning! There is NO operator in current proposal!!!
There are many new stakers after delisting did not see my proposal 34 - https://forum.tornado.ws/t/proposal-34-cheating-relayers-patch/227/5
We want to add new relayer control function - an operator who can unregister relayer in the case of cheating immediately and operator can not turn malicious, bcs operator will be one biggest relayer or multisig of 3-5 biggest relayers and if they maliciously unregister someone, governance can punish them in 7 days with proposal and restore unregistered relayer and choose new operator without problem
