Bitcoin developers have proposed Bitcoin Improvement Proposal (BIP)-361, which calls for freezing coins vulnerable to quantum computing threats. The plan requires users to migrate to quantum-resistant addresses, sparking significant backlash within the community over concerns of central control and the violation of Bitcoin's core principles.
- 01BIP-361 aims to protect Bitcoin from potential quantum computing threats by requiring users to migrate to quantum-resistant addresses.
- 02The proposal includes a phased approach to freezing vulnerable coins over several years, raising concerns about user control.
- 03Community backlash highlights fears of centralization and loss of permissionless control, fundamental to Bitcoin's ethos.
- 04Developers argue the proposal is a necessary defensive measure to protect the Bitcoin ecosystem from future quantum threats.
- 05A recent Google report suggests that quantum computers could compromise Bitcoin's cryptography sooner than previously thought, with 2029 cited as a potential deadline.

Bitcoin developers are addressing potential threats from quantum computing with the updated Bitcoin Improvement Proposal (BIP)-361, which requires holders to migrate their coins to quantum-resistant addresses or risk permanent freezing. This proposal, prompted by a recent Google report warning that quantum machines could compromise Bitcoin's cryptography, outlines a phased approach to phasing out vulnerable address types over several years. The first phase would block new transactions to old-style addresses three years post-activation, while the second phase would invalidate old signatures, effectively freezing the coins. The proposal has sparked backlash within the Bitcoin community, with critics arguing that it undermines the cryptocurrency's foundational principle of sovereign control. Developers maintain that the proposal is a necessary defense against potential quantum threats, emphasizing the need to protect the Bitcoin ecosystem from malicious actors. As of March, approximately 6.7 million BTC were held in vulnerable addresses, highlighting the urgency of this initiative.

If implemented, BIP-361 could significantly affect how Bitcoin holders manage their assets, forcing them to adapt to new security protocols or risk losing access to their funds.
