Proposed Bitcoin Protocol Could Lock Out Quantum-Related Coins

Bitcoin's developer community has proposed a new protocol that could force users to migrate their coins to quantum-resistant addresses, potentially freezing those that don't comply. This move aims to defend against future quantum computers that could compromise the Bitcoin blockchain. Meanwhile, research has highlighted the security risks associated with AI agents handling crypto payments, and a recent DNS hijacking incident has affected CoW Swap, a decentralized trading interface. Additionally, the XRP Ledger has integrated zero-knowledge proofs, enabling financial institutions to transact privately on the public blockchain while meeting regulatory requirements. Other news includes updates on regulatory and policy developments in the cryptocurrency space.
