Bitcoin Developers Propose Freezing Coins to Counter Quantum Threats

The promise of Bitcoin has always been that users have full control over their coins, with no external entity able to access them without the private key. However, this promise is now being challenged by the developer community as they attempt to build defenses against future quantum computers that could compromise the blockchain. A proposal, known as Bitcoin Improvement Proposal (BIP)-361, has been updated to include a plan to force users to migrate their coins to new quantum-resistant addresses or face having their coins frozen permanently by the network. This move is in response to a recent Google report that warned a sufficiently powerful quantum machine could compromise the Bitcoin blockchain with less firepower than initially estimated. The proposal is met with backlash from the community, who see it as a violation of Bitcoin's fundamental principle of sovereign control over funds.
