Quantum Threat Looms Over Trillions in Digital Assets

The cryptographic locks protecting trillions of dollars in digital assets were designed for a world without quantum computers. However, that world is ending faster than most people in crypto realize.

NIST finalized its first three post-quantum cryptography standards in August 2024 and told every organization using public-key cryptography to begin migration immediately.

The threat is not to the Bitcoin network's ability to produce blocks. It is to the ability of individual users to prove ownership of their coins, as digital signatures are the mechanism through which funds are authorized.

Approximately 4 million BTC were held in addresses with publicly exposed keys. At current prices, this amounts to approximately $315 billion worth of Bitcoin that sits in addresses where a cryptographically relevant quantum computer could derive the private key directly from on-chain data, with no warning and no recourse.
