币界网报道：Bitcoin pioneer Hal Finney, known for receiving the first-ever Bitcoin transaction from Satoshi Nakamoto, has dismissed the "paper Bitcoin" concept as impractical. In a recent discussion, Finney argued that creating Bitcoin-backed paper certificates would undermine the cryptocurrency's core decentralized nature. He emphasized that Bitcoin's value lies in its ability to operate without trusted third parties, and introducing paper claims would reintroduce counterparty risk. Finney also pointed out technical challenges, noting that verifying paper Bitcoin authenticity would require trusting centralized entities, contradicting Bitcoin's trustless design. The comments come amid growing debate about bridging digital and physical Bitcoin representations while maintaining the network's security principles.
