Bitcoin Developers Propose Quantum Defenses, Potentially Freezing Vulnerable Coins

The core promise of Bitcoin, that users have full control over their coins, is being reevaluated as developers propose measures to defend against future quantum computer attacks. A recent update to the Bitcoin Improvement Proposal (BIP)-361 suggests that coins in quantum-vulnerable addresses may be frozen to prevent theft. This move has sparked controversy within the community, with some arguing it undermines the fundamental principle of sovereign control over funds. The proposal outlines a three-phase plan to migrate coins to quantum-resistant addresses, with the ultimate goal of protecting the Bitcoin ecosystem from potential quantum threats. The community remains divided, with some viewing the proposal as a necessary defensive measure, while others see it as an overreach of authority.
