Paradigm Proposes Quantum-Resistant Timestamp Solution for Satoshi-Era Bitcoin

Venture fund Paradigm has proposed PACTs, a quantum-resistant timestamp solution designed to protect early Bitcoin holdings from future quantum computing threats. The design would allow long-term Bitcoin holders, particularly those with Satoshi-era coins, to privately timestamp proof of key control without moving funds or signaling activity onchain. The proposal addresses a worst-case scenario where quantum computers could break the cryptographic protections of vulnerable early Bitcoin addresses. PACTs functions as an escape hatch rescue mechanism, enabling holders to prepare for quantum threats while maintaining privacy and avoiding onchain exposure.

Perspective of Paradigm

• ▪The PACTs proposal addresses worst-case quantum scenarios for Bitcoin holders.
• ▪Paradigm's PACTs design enables private proof of key control before quantum computers become a threat to Bitcoin.
• ▪PACTs provide a rescue mechanism for vulnerable early Bitcoin holdings without requiring onchain fund movement.

Perspective of Satoshi-era Bitcoin holders

• ▪Early Bitcoin holders could use PACTs to demonstrate key control without revealing their holdings or activity.
• ▪Satoshi-era Bitcoin holdings are particularly vulnerable to quantum computing threats.
