A new proposal from Paradigm could allow Satoshi Nakamoto to prove control of his Bitcoin without moving any coins, providing a potential escape hatch from quantum computing threats. The plan, called PACTs (Privacy and Cryptography Timestamps), aims to protect old UTXOs by leveraging timestamps to prove ownership.
"It might be the only way to save old UTXOs from quantum computers," one expert noted.
The proposal has ignited controversy among developers, with some warning that it could lead to an eCash airdrop and unintended forks. The core idea is to use timestamps to create a quantum-resistant proof of ownership, enabling Satoshi to secure his wealth without broadcasting transactions that would expose his keys.
For retail investors, the debate highlights growing concerns about quantum threats to Bitcoin's security. While large holders like Satoshi may benefit from PACTs, everyday users may need to migrate to wallets that support quantum-resistant signatures.
