Bitcoin developers have introduced BIP-361, a proposal aimed at freezing 6.9 million Satoshi-era coins to protect against potential quantum computer threats. The plan, led by Jameson Lopp and others, suggests a three-phase upgrade that could render un-migrated Bitcoin permanently unspendable after a set deadline. This proposal has sparked debate within the Bitcoin community, with supporters advocating for enhanced security and critics arguing it violates Bitcoin's core principle of user ownership rights. The BIP-361 proposal builds on the earlier BIP-360, introducing a safer address type called Pay-to-Merkle-Root (P2MR). The upgrade aims to prevent future quantum machines from compromising Bitcoin's security. Developers describe it as a soft upgrade that enhances safety without altering Bitcoin's current functionality. However, the community remains divided, with concerns that freezing coins could set a precedent for future control over Bitcoin holdings.
