Bitcoin Developers Propose Freezing Coins Vulnerable to Quantum Attacks
The promise of Bitcoin has always been that no one can access your coins without your private key. However, this promise is now being challenged by the developer community, who are working to build defenses against future quantum computers that could compromise the Bitcoin blockchain. A recently updated proposal, called Bitcoin Improvement Proposal (BIP)-361, suggests forcing Bitcoin holders to migrate their coins to new quantum-resistant addresses or face having their coins frozen by the network. This move is in response to a Google report warning that a sufficiently powerful quantum machine could compromise the Bitcoin blockchain with less firepower than initially estimated. The proposal has sparked backlash from the community, who see it as a threat to the fundamental principle of sovereign control over funds. The proposal involves a three-phase process, starting with blocking new bitcoin from being sent to old-style addresses, then rendering old-style signatures invalid, and finally, potentially allowing holders to recover frozen coins using zero-knowledge proof.
