Bitcoin quantum-resistant SHRINCS draft: signatures from 548 to 5,777 bytes
- —Public key is 48 bytes; stateful signatures span 548–4,619 bytes, stateless ones 5,777 bytes
- —If key records are lost, the scheme falls back to the larger stateless signature
- —At 10 satoshis per byte, a 548-byte signature costs 2,370 sats versus 15,450 for 5,777 bytes
- —The SHRINCS spec remains a draft with its security proof section unfinished
Why it matters: Moving Bitcoin to quantum-resistant signatures will require careful key-state management and larger transactions.
