Paradigm’s PACTs Offer Bitcoin Holders Quantum Security
- Dan Robinson of Paradigm proposed Provable Address-Control Timestamps (PACTs) on May 1, 2026.
- Over 1.1 million BTC in Satoshi-linked wallets face exposure to quantum threats, valued at roughly $75 billion.
- PACTs use existing Bitcoin tools for private timestamping without requiring an onchain transaction or public signal.
- The proposal requires future STARK verification support and community consensus to activate a rescue path.
- If implemented, PACTs could prevent forced coin migration by proving control before quantum computers become a threat.
Paradigm’s PACT proposal aims to protect dormant Bitcoin from potential quantum computing risks by offering a private method for timestamping address control without public disclosure or immediate protocol changes. This approach provides an alternative to forced migrations that might expose wallet holders’ identities.
With over $75 billion in Bitcoin potentially vulnerable, the adoption of PACTs could secure long-term holdings against future quantum threats while maintaining privacy and security for current holders until consensus is reached on implementing protective measures.(Source)
