Paradigm researcher proposes model to protect dormant BTC from quantum threats

Dan Robinson, a researcher at crypto investment firm Paradigm, has proposed a new model to protect dormant Bitcoin, including those belonging to founder Satoshi Nakamoto, from future quantum computing threats, The Block reported. The model, called a provable address control timestamp (PACT), offers a way for Bitcoin holders to prove they own a wallet before quantum computing technology advances to the point where it can derive private keys. This model utilizes the blockchain's native timestamping system. Holders can prove their ownership and have it timestamped on the blockchain, creating a record of ownership to guard against future quantum attacks. The proposal is described as a potential solution to a key issue in the quantum-Bitcoin debate: how to protect the ownership and privacy of long-dormant Bitcoin addresses.
