A fresh round of discussion around whether crypto users should enter “bunker mode” before AI or quantum computing can expose wallet private keys is now drawing attention to a more difficult problem: institutional readiness. According to CoinDesk, custodians face a wider operational burden than individual holders because they may need to upgrade key management, approval, and audit systems before any emergency migration begins.
Project Eleven CEO Alex Pruden said institutions are already preparing for post-quantum migration outside the blockchain layer. He pointed to a major complication for firms holding multiple types of digital assets: different blockchains may eventually adopt different quantum-resistant signature schemes and migration paths, leaving institutions to adapt to several cryptographic systems at once.
Quantus co-founder and CEO Christopher Smith said AI is accelerating advances in both quantum hardware and software, and argued that tail-risk from a quantum attack should be incorporated into portfolio decisions as part of an institution’s fiduciary duty. The timeline for quantum computers to break the public-key cryptography used by Bitcoin and Ethereum remains unclear. Even so, the industry is increasingly treating the next few years as a window to build migration plans, rather than waiting to react after an attack occurs.
A debate over whether crypto users should enter “bunker mode” before AI or quantum computing can expose wallet private keys is shifting toward a harder question for the industry: how institutions would handle the transition.
According to CoinDesk, custodians face a more complicated task than individual users because they would need to upgrade key management, approval, and audit systems before any emergency migration takes place.
Institutions may have to support multiple migration paths
Project Eleven CEO Alex Pruden said institutions have already started preparing for post-quantum migration outside blockchain networks themselves. He said firms that hold multiple types of assets could run into a particular challenge if different blockchains end up adopting different quantum-resistant signature schemes and different migration routes. In that case, one institution may need to adapt to several cryptographic systems at the same time.
Quantum tail-risk enters portfolio discussions
Quantus co-founder and CEO Christopher Smith said AI is speeding up progress in both quantum hardware and software. He said the tail-risk of a quantum attack should be included in portfolio decision-making, calling that part of an institution’s fiduciary responsibility.
No clear timetable, but a planning window is taking shape
There is still no clear timeline for when quantum computers might break the current public-key cryptography used by Bitcoin and Ethereum. Even so, the industry is gradually treating the coming years as a window to put migration plans in place, rather than waiting until an attack forces an emergency response.
