The Nice Consensus Cleanup proposes to make 64 byte transactions consensus invalid, for numerous causes. They’ve been non-standard for years and seem to serve no helpful goal.
It seems that any such transaction may be malleated into a special dimension, in order that in apply there isn’t any confiscation danger even when such a transaction have been helpful. I am making an attempt to know this side higher.
Given a UTXO A, which both already exists or is freshly mined below the present consensus guidelines (e.g. by means of a non-standard transaction).
Given a 64 byte transaction T that spends it (non-standard by definition).
With out entry to the secrets and techniques (if any) that have been used to generate T (non-public key, hash pre-image, and so on.)
Is it at all times potential to vary T right into a consensus legitimate transaction T' that spends A?
Moreover, if I perceive appropriately, it isn’t potential for any 64 byte transaction T to ship cash to a vacation spot B that may be a safe (i.e. >= 20 byte) public key (hash).
Regardless, for each B, is there a malleated T' that preserves B (not less than nonetheless spendable by the non-public key b)?
If the latter is simply too arduous to show, may one may present that any T may be malleated by an attacker to divert cash away from B.
