We made the following changes to BIP-360 (Pay to Quantum Resistant Hash) PR:
- P2QRH (Pay to Quantum Resistant Hash) is now taproot (P2TR) but with the quantum vulnerable key-spend path removed.
- PQ signatures have been moved to a future BIP (coming soon).
- The plan for PQ signatures is to redefine OP_SUCCESSx opcodes: OP_CHECKMLSIG
Below we go into these changes one by one, see BIP-360 PR for full details (BIP-360 mediawiki render as of 7/7/2025).
P2QRH is now script-spend only P2TR (taproot), i.e. no quantum vulnerable key-spend. P2QRH outputs commit directly to the tapleaf merkle root computed by taproot.

Taproot code could be an efficient way to make transactions.
Can you break that down a bit?
Taproot allows for the concealment of spending conditions in transactions, making it more difficult for external observers to determine the details of the transaction. It reduces the size of complex transactions, which helps to lower transaction fees and increase the processing capacity of the Bitcoin network. This is from own experience.
I thought you were saying Taproot transactions were kinda inefficient, based on what you said before. But now it doesn’t sound like that at all. Did I get it wrong?
0 sats \ 3 replies \ @d680ecaa8e 1h Taproot code could be an efficient way to make transactions. I said efficient from beginning, but no worries you may misread it no problem
The word 'could' kinda threw me off.
No problem friend
I need 1-2 sats to start posting” I can help you send it via your Speed Wallet invoice (as long as it’s not expired 😄)
