overkill in this instance. I agree 32 bits is likely too short, unless always paired with a pubkey.
UUIDs are 128 bit (16 byte). Thats on par with the uniqueness afforded by a 12 word seed phrase.

oh, i meant 64 bits. lol, 64 bytes is waaay overkill.
if the data has a frame, 64 bits will generally be enough.
for fingerprints, yeah, i hadn't really thought that much about it tbh, but 128 bits would be just about right.
