Overview
- Galaxy Digital opened applications on Tuesday for a Bitcoin Quantum Readiness Initiative that pledges up to $5 million in milestone‑based grants, a research program and a Quantum Advisory Council of academic experts.
- On Thursday nine firms led by Strategy announced a Bitcoin Security Consortium that pledged $15 million over three years while keeping each member’s funding decisions independent of protocol governance.
- Both efforts will finance practical defenses such as post‑quantum signature schemes, migration tooling to move coins off addresses that expose public keys, and independent code audits.
- Researchers estimate roughly 6.9 million BTC sit in outputs with exposed public keys that would be vulnerable if a cryptographically relevant quantum computer is built, but experts say no such machine exists today.
- Adoption remains the core challenge because any change requires design, review, testing and coordinated upgrades across wallets, exchanges, custodians and users, a process that could take years even with new funding and federal post‑quantum timetables.
