The state of Illinois decided to make a difference in the world of blockchain, and it succeeded. The local Senate wants to be able to... cancel bitcoin transactions.
According to the Digital Property Protection and Law Enforcement Act, validators must cancel transactions and return the funds to the sender or transfer them to the state Treasury if ordered by the state's attorney. The same goes for smart contracts, which must be rescinded upon a valid court request.
Shall we expect a manual sunset in the next bill?
