A new proposal by Dan Robinson, a general partner at Paradigm, introduces a method to protect Bitcoin from quantum computing threats without requiring the movement of coins. The proposal, known as Provable Address-Control Timestamps (PACTs), aims to secure dormant Bitcoin, including the 1.1 million attributed to Satoshi Nakamoto, by timestamping proof of ownership without revealing it publicly. This approach counters the potential vulnerability of old wallets with exposed public keys to quantum attacks. PACTs utilize a cryptographic commitment using a random salt and BIP-322, allowing holders to prove ownership without spending. The commitment is timestamped on the Bitcoin blockchain via OpenTimestamps. If a future soft fork freezes quantum-vulnerable coins, a STARK proof can be used to release the coins, ensuring security against quantum computers. However, this requires Bitcoin to adopt a STARK verification protocol, necessitating a separate soft fork and community consensus. The proposal offers a nuanced solution to the BIP-361 debate, balancing quantum security with dormant property rights.
