# Bitcoin Core Contributor Examines AI and Quantum Risks to Security By Simon Yoon Canonical URL: https://www.tokenpost.com/news/technology/29018 Published: 2026-10-09T13:45:30.000Z Updated: 2026-10-09T13:45:30.000Z Section: Technology > Antoine Poinsot discussed Justin Drake’s viral post, potential quantum theft, proposed protocol changes and multisignature safeguards. Bitcoin Core contributor Antoine Poinsot examined artificial intelligence and quantum-computing risks to Bitcoin (BTC) security, including possible protocol changes and wallet safeguards, in a discussion published Oct. 9. Poinsot addressed whether Justin Drake’s viral post about Bitcoin address security amounted to fear-mongering. The discussion focused on the need for evidence when evaluating security claims and on how developers can prepare for potential quantum attacks. Quantum computing could create two distinct risks for Bitcoin: the theft of funds from vulnerable addresses and the freezing of coins that cannot be moved. The conversation also examined whether hiding public keys behind hashes would materially reduce that exposure. The participants reviewed several proposed approaches, including BIP 360, BIP 361 and P2TR v2. They also discussed BIP 54, a proposed consensus cleanup that would bundle four fixes for long-standing Bitcoin bugs into a single soft fork. Activating the proposal would require consensus among participants. The discussion included lessons from a Coldcard incident and methods for reducing single points of failure. Multisignature arrangements require multiple keys to authorize a transaction, while Liana provides another structure for managing Bitcoin spending conditions. The practical challenge for exposed addresses is migration. Users and custodians would have to transfer funds from exposed addresses before quantum technology could make their public keys exploitable, as detailed in [Bitcoin’s quantum exposure](). The quantum issue differs from [AI-assisted flaw discovery]() in wallets and other software. Finding implementation weaknesses is separate from the possibility of AI breaking Bitcoin’s cryptography. Poinsot’s discussion linked both risks to preparation, while the proposed protocol changes remain subject to developer and community consensus. ## Links in this article - [Bitcoin’s quantum exposure](https://www.tokenpost.com/news/technology/27549) - [AI-assisted flaw discovery](https://www.tokenpost.com/news/technology/28273)
