Galaxy (GLXY) Commits $5 Million to Prepare Bitcoin for the Quantum Threat

Galaxy Digital launched a Bitcoin Quantum Readiness Initiative today, a program that commits up to $5 million in developer grants, a research effort, and a new advisory council to harden the network against the arrival of powerful quantum computers.

The Nasdaq-listed firm framed the multi-pillar effort as an attempt to close a gap between two worlds moving at different speeds.

“There’s a gap between the quantum computing world, which is moving fast, and the Bitcoin development world, which is just beginning to engage with post-quantum cryptography in earnest,” said Alex Thorn, head of firmwide research at Galaxy, whose team has tracked the threat for Wall Street and cast it as a long-term engineering problem rather than a crisis.

Bitcoin’s security rests on elliptic curve cryptography, a scheme that a machine running Shor’s algorithm could break by deriving a private key from an exposed public key.

An attacker with such a tool could forge a signature and drain a wallet, with nothing on-chain to flag the theft. No such computer exists today, yet the estimated timeline for one keeps compressing, a trend the Bitcoin Policy Institute has warned narrows the window for the network to upgrade. to network...
