The European Union's Data Act has been revised to require smart contracts to contain a kill switch, according to a proposal agreed upon by the EU's Council. The proposal has raised concerns in the blockchain community, as it undermines the supposed automation and unalterability of smart contracts. The final wording of the law now has to be negotiated between the European Parliament and the council mediated by the European Commission. The new rules apply to contracts that make data available as part of controls on smart-home appliances like cars and fridges, but how far they actually go is not clear. Some in the blockchain community have expressed doubts that most smart contracts can meet the regulations as drafted by the Parliament.
