Bitcoin Quantum Migration Proposal Raises Nakamoto Dilemma
Bitcoin developers, including Jameson Lopp, proposed BIP-361 in mid-April, planning to phase out old addresses vulnerable to quantum attacks over five years, with un-migrated coins being frozen.
This includes approximately 1.1 million bitcoins belonging to Satoshi Nakamoto, currently valued at about $84 billion.
Dan Robinson, a partner at Paradigm, proposed the PACTs solution on Friday, which proves ownership through "provable address control timestamps" without moving the coins.
PACTs utilize STARK zero-knowledge proofs, allowing for safe redemption after a quantum threat triggers a soft fork, without exposing address, amount, or timestamp information.
BIP-361 aims to protect the network from quantum theft risks but forces dormant holders to act sooner; PACTs provide a privacy-preserving path for long-term holders to retain assets without having to publicly reveal themselves.
The flow of quantum-safe migration funds to new addresses and proof mechanisms puts pressure on old address holders, while protocol developers and quantum security technology providers benefit.

Jameson Lopp has long served as a co-founder of Casa and focuses on Bitcoin self-custody security, having previously promoted cold storage and multi-signature solutions, and has publicly discussed quantum threats for years; BIP-361 was proposed by him and five developers as a direct response to quantum research reports from institutions like Google.
On the capital path, Paradigm, as a significant investor in crypto infrastructure, intervenes in Bitcoin's core governance through Dan Robinson's research proposal, aiming to reduce the systemic impact of quantum risks on the entire ecosystem (especially early large holders), and to avoid market turmoil and trust crises caused by large-scale coin freezes.
Similar to the considerations of compatibility and old addresses during the 2017 SegWit upgrade, and the optimization of privacy and efficiency with Taproot, Bitcoin is currently at a critical stage of transitioning from classical cryptography to post-quantum cryptography.
Structural Judgment
Essentially, this belongs to technological substitution and regulatory change: Quantum computing forces Bitcoin to achieve signature mechanism replacement through soft forks, while zero-knowledge tools like PACTs reconstruct the "proof of ownership" mechanism without compromising decentralized privacy, allowing for compatibility between technological upgrades and historical legacy assets.
