Proposal Could Put Quantum-Related Bitcoin Holdings on Lockdown

A proposed Bitcoin update could render quantum-related coins unusable, as the community works to defend against potential quantum computer threats. Bitcoin's core promise of secure, private transactions is being reevaluated in light of emerging quantum technologies that could compromise the blockchain. Jameson Loop and other contributors have put forth Bitcoin Improvement Proposal (BIP)-361, which would require users to migrate their coins to quantum-resistant addresses or risk having them frozen by the network. This development comes as a recent Google report highlights the potential vulnerability of the Bitcoin blockchain to quantum attacks. Meanwhile, researchers have found that AI agents handling crypto payments may not be secure, with 'LLM routers' posing a significant attack vector for malicious actors. In other news, CoW Swap has temporarily halted services due to a DNS hijacking incident, and the XRP Ledger has integrated zero-knowledge proofs to enable private transactions on the public blockchain.
