Bitcoin is not immediately vulnerable to quantum computers, but industry estimates suggest the real threat window may be 5 to 10 years away. As BIP-360 and BIP-361 gain attention, investors should watch address reuse, wallet upgrades, and post-quantum migration plans across major blockchains.
A new Bitcoin Improvement Proposal, BIP-361, suggests forcing users to migrate funds to quantum-resistant addresses or risk having legacy coins frozen. The idea has ignited debate over security, ownership and Bitcoin’s core principles.
Bitcoin’s proposed BIP-361 would push holders to migrate funds to quantum-resistant addresses or risk having legacy coins frozen. The debate highlights rising concern over quantum threats and the tension between network security and Bitcoin’s core self-custody principle.
Bitcoin’s BIP-361 proposes a post-quantum migration path that could freeze coins left on legacy signature schemes. The idea has reignited debate over whether Bitcoin’s core principle of private-key-based ownership can coexist with protocol-level defenses against future quantum threats.
Paradigm has proposed PACTs, a system that lets dormant Bitcoin holders privately timestamp proof of key ownership before quantum threats emerge, potentially preserving a future rescue path for Satoshi-linked coins.

Postquant Labs has introduced Quip, a quantum-resistant Bitcoin wallet using WOTS+ signatures and a Layer 2 design. While it avoids changes to Bitcoin’s core network, critics question whether off-chain approaches can fully address long-term quantum risks.
Postquant Labs has introduced Quip, a Bitcoin wallet using WOTS+ signatures and a Layer 2 smart contract model to offer quantum-resistant protection without changing Bitcoin’s core protocol, though debate over its effectiveness continues.
