Bitcoin developers are trying to build quantum defenses. Your coins could pay the price.

Bitcoin developers have introduced BIP-361, a proposal to protect the blockchain against potential future quantum computing attacks by phasing out legacy, quantum-vulnerable addresses. The plan suggests a three-phase migration that would eventually invalidate old signature types, effectively freezing funds in non-compliant wallets if owners fail to move them to quantum-resistant addresses.

This proposal has ignited intense controversy within the community. While proponents argue the measure is a necessary defensive step to prevent malicious actors from draining billions in BTC, critics argue that the threat of forced migration and account freezing violates Bitcoin's core promise of sovereign, permissionless control over one's own assets.
