Proposal Aims to Protect Bitcoin from Quantum Threats

A proposed Bitcoin update could render coins vulnerable to quantum attacks unusable, while AI agents are increasingly handling crypto payments, and DeFi platforms face ongoing security risks. The Bitcoin Improvement Proposal (BIP)-361 aims to migrate coins to quantum-resistant addresses, effectively freezing those that don't comply. Meanwhile, research highlights the potential security flaws in AI-powered crypto payment infrastructure, and a decentralized trading interface, CoW Swap, recently suffered a domain name system (DNS) hijacking incident. In other news, the XRP Ledger has integrated zero-knowledge (ZK) proofs to enable private transactions on the public blockchain, addressing a significant barrier to institutional adoption.
