BIP-360 P2MR proposes a bc1z output type that works like Taproot without the key path, so coins at rest no longer sit behind an exposed public key. Here is what it changes, what it costs, and what it leaves open.

BIP-361 Explained: Bitcoin’s Plan to Sunset Quantum-Vulnerable Coins
BIP-361 is a draft plan to phase Bitcoin’s quantum-vulnerable signatures out in two stages, roughly three and five years after a still-undefined activation. Here is what it would do, what it means for Satoshi’s P2PK coins, and why it is not in force.
Which Bitcoin Addresses Are Vulnerable to Quantum Computers?
Quantum computers threaten Bitcoin addresses whose public keys are visible on-chain, not the blockchain itself. This guide ranks P2PK, reused, Taproot and unspent hashed addresses by exposure and explains what you can do now.
Can Quantum Computers Break Ethereum? Risks, Qubits and the 2029 Plan
No quantum computer can break Ethereum today, but its elliptic-curve signatures have a known weakness and Google’s 2026 estimates moved the goalposts. Here is what is exposed, how many qubits an attack needs, and how Ethereum plans to be post-quantum by 2029.
