THORChain developer Chad Barraford said there were ways to restrict the movement of funds linked to the Bitget hack, but a practical response was difficult because validator consensus takes time.
In an interview with Unchained, Barraford said THORChain currently does not have a function to immediately block specific wallets or transactions. Barraford said that even if a separate blocking mechanism were introduced, a hacker could move funds to other addresses while validators complete consensus.
Barraford explained that reaching the two-thirds validator consensus needed to carry out certain measures takes about three days on average and as long as two weeks. Barraford added that shortening the response time would require changing the protocol structure to give some participants stronger control. If swaps are already under way, Barraford said, a response becomes even more difficult.
Barraford said stopping transactions would require redistributing funds through a vault migration, which would also need approval from more than two-thirds of validators and could take one to two weeks. Barraford added that it is theoretically possible to preemptively block Ethereum addresses confirmed to be linked to a hack, but if the hacker moves funds to new addresses, trading can resume, making it difficult for that to serve as a fundamental solution.
