BIP-360
P2QRH
A Bitcoin Improvement Proposal defining a quantum-resistant output type, sometimes called Pay to Quantum Resistant Hash. It is a proposal under discussion, not an activated consensus rule.

A Bitcoin upgrade introducing bc1p addresses and Schnorr signatures. Taproot key-path spends place a public key in the output, so a funded Taproot address exposes a key earlier than a comparable P2PKH address.
A backwards-compatible consensus change where upgraded nodes enforce stricter rules and old nodes still accept the chain. A post-quantum signature scheme would most plausibly reach Bitcoin as a soft fork.
Cryptographic algorithms designed to resist attacks by both classical and quantum computers. PQC runs on ordinary hardware today — it is not quantum technology, it is classical maths chosen because no efficient quantum attack against it is known.
