Dan Robinson, a researcher at cryptocurrency investment firm Paradigm, has proposed a new model to protect dormant Bitcoin, including that of Bitcoin creator Satoshi Nakamoto, from future quantum computing threats. According to The Block, this is called 'Provable Address Control Timestamp (PACT)' and provides a way for Bitcoin holders to prove ownership of their wallet before quantum computing technology advances to a point where private keys can be deduced. This model utilizes the blockchain's fundamental timestamp system. Holders can prove their ownership of Bitcoin and timestamp it on the blockchain, creating a record of ownership in preparation for future quantum attacks. The model is described as offering a potential solution to a major point of contention in the quantum Bitcoin debate: how to protect the ownership and privacy of long-dormant Bitcoin addresses.
