Bitcoin pioneer Hal Finney's early work on zero-knowledge proofs highlighted in unearthed video
A recently discovered video from the Crypto '98 conference, held on Aug. 26, 1998, has shed light on the pioneering work of early Bitcoin innovator Hal Finney. The video shows Finney discussing the concept of zero-knowledge proofs, a cryptographic protocol that allows a user to convince another user of a claim's truthfulness without disclosing any information about the claim itself.
While zero-knowledge proofs were considered a possibility at the time of Finney's speech, they were deemed inefficient or impractical due to hardware limitations. Today, however, the crypto industry is actively discussing and debating how to best implement zero-knowledge proofs, primarily to scale the Ethereum network.
The footage was taken from the 18th annual International Cryptology Conference at the University of California, Santa Barbara, also known as "Crypto '98". In his talk, Finney credits Ronald Cramer and Ivan Damgard for having invented the zero-knowledge proof system he was demonstrating and praises it for its efficiency and flexibility.
Finney is widely recognized as a significant figure in the cryptocurrency industry. He was a computer scientist who made substantial contributions to privacy-enhancing technology, including the creation of the first fully anonymous re-mailer. He also developed the first reusable Proof of Work system, which preceded Bitcoin by almost five years.
On January 11, 2009, Finney became the first recipient of Bitcoin after receiving a transfer of 10 BTC from the pseudonymous founder, Satoshi Nakamoto. He was known to have worked closely with Nakamoto in the early days of Bitcoin, leading to speculation that he could be Nakamoto himself. However, Finney denied this theory.
Finney was diagnosed with ALS, a rare neurological disease, and passed away in 2014. His body was cryopreserved by the Alcor Life Extension Foundation in Arizona. The rediscovered video has allowed many to hear Finney’s voice for the first time and appreciate his contributions to the development of cryptocurrencies.
