Numerous outstanding Bitcoin consultants, together with Adam Again, Jimmy Tune and Andreas Antonopoulos, have raised some issues over the implementation of restrictive covenants, particularly with the BIP119.
Specifically, Antonopoulos has voiced issues over “recursive covenants” that the brand new replace may convey, thereby deteriorating the community. A recursive covenant happens when a programmer restricts a transaction, however he does it in a approach that restricts one other transaction after that, beginning a domino impact leading to future limitless recursive covenants.
Blacklisting and dangers of censorship and confiscation
Whereas locking up the place a Bitcoin might be spent is advantageous to make sure extra safety, it additionally supplies grounds for censorship, and management by governments, which might hinder the very existence of Bitcoin. Authorities may probably drive exchanges to withdraw solely to covenants with some management over the coin.
Whereas this similar threat already exists, since governments can ask exchanges to ship solely to addresses with a taproot spend path or multi-sig managed by them, may the implementation of covenants facilitate malicious functions the place it will make it simpler for governments to implement a type of on-chain KYC?
Fungibility threats
Covenants would possibly intrude with Bitcoin’s fungibility — the flexibility of every Bitcoin to be equivalent in perform and high quality.
Whereas helpful for safety and scalability, covenants would change the properties of particular Bitcoin items, primarily creating several types of digital foreign money, distinct in accordance with what could possibly be spent or the place it could possibly be despatched.
