Anchorage Digital Outlines Post-Quantum Migration Strategy for Institutional Assets

Anchorage Digital Outlines Post-Quantum Migration Strategy for Institutional Assets Federally chartered crypto bank Anchorage Digital has unveiled its post-quantum compute (PQC) preparedness strategy, establishing an operational blueprint to safeguard digital asset holdings against emerging quantum decryption threats. Recognizing that quantum algorithms such as Shor’s algorithm pose a direct threat to public-key digital signatures, the firm has deployed a multi-layered security infrastructure designed to neutralize “harvest now, decrypt later” adversary models. To secure client holdings at rest and in transit, Anchorage Digital has integrated three foundational cryptographic safeguards: Hash-Based Bitcoin Address Conventions: Utilizing hash-based address models that prevent public key exposure prior to transaction execution, keeping dormant Bitcoin holdings quantum-safe at rest. Quantum-Resistant TLS: Deploying hybrid post-quantum key encapsulation across internal enterprise systems and managed ChromeOS workforce devices to shield transport-layer traffic from interception. Agile HSM Architecture: Integrating post-quantum algorithms into its Hardware Security Module (HSM) architecture, enabling firmware updates to adopt new NIST-finalized signature standards without requiring system overhauls. In parallel with infrastructure deployment, Anchorage Digital published original cryptographic research to address systemic migration challenges across public blockchains. The firm introduced the Post-Quantum Turnstile, a zero-knowledge framework utilizing STARKs that allows legacy credential holders—covering an estimated two-thirds of circulating Bitcoin—to transition signing authority to post-quantum keys without exposing private or public key material. Additionally, the company open-sourced sqisign-rs, a Rust implementation of the SQIsign signature scheme based on supersingular elliptic curve isogenies, offering a compact signature footprint roughly seven times smaller than Falcon for on-chain execution.
