Big banks expand bitcoin custody vaults, but key issue turns to quantum computers

Global big banks are expanding bitcoin custody as a strategic business, but a report warns today’s crypto custody infrastructure could face structural risks in a future quantum-computing era. Swiss digital asset technology company Taurus said major custodians carry significant risk during a shift to quantum-resistant cryptography. It said upgrades require blockchain protocol changes and broad coordination. The report argues MPC may face bigger hurdles than HSM, though the view is contested.

Stellar pursues quantum-resistant migration without address changes, signing key replacement central

The Stellar Development Foundation unveiled QPP, a roadmap to prepare the Stellar (XLM) network for quantum computers, and said it aims to complete a shift of all accounts to quantum-resistant signatures by the end of 2027. The plan is designed to keep existing addresses and transaction histories intact while replacing only signing keys. It outlines a three-stage rollout from 2026, adds NIST-standardised ML-DSA support, and raises dormant-account handling as a remaining issue.

SKT develops chip-based quantum cryptography technology in joint EU research

SK Telecom said on Monday it will develop next-generation quantum cryptography technology through the European Union\'s Horizon Europe research programme. The three-year multinational project involves partners in three European countries and aims to implement and demonstrate a QPIC-AI-based quantum key distribution system to strengthen communications security. SKT will develop the PIC-based QKD system, apply AI functions and build and verify a testbed, while ETRI will develop optical chips for transmitters and receivers.
