The crypto community’s latest discovery is a video from a quarter-century ago. In this footage, early Bitcoin BTC/USD pioneer Hal Finney is seen discussing the potential of zero-knowledge proofs, a cornerstone of cryptographic technology.
What Happened: The footage originates from the Crypto ’98 conference, which took place in Santa Barbara, California, on Aug. 26, 1998. The video features Finney elaborating on the concept of zero-knowledge proofs.
Zero-knowledge proofs or ZK-proofs are cryptographic protocols enabling a user to validate a claim’s authenticity without divulging any specifics of the claim. First coined in 1985, this concept predates the launch of Bitcoin by over a decade.

In the video, Finney delineates how to execute a zero-knowledge proof on a SHA-1 hash, a technique for transmitting an encrypted claim without exposure to its contents. At that time, zero-knowledge proofs were perceived as feasible but inefficient due to hardware constraints.
Presently, the crypto sector is actively exploring the optimal methods for applying ZK-proofs, principally to expand the Ethereum network’s scope.
Finney was a prominent figure in cryptocurrency’s early phase. He was the inaugural recipient of Bitcoin, acquiring 10 BTC from the enigmatic founder of cryptocurrency, Satoshi Nakamoto. Finney, who passed away in 2014, made substantial contributions to privacy-centric technology.
According to posts on the BitcoinTalk forum in 2013, Finney consistently denied being the inventor of Bitcoin. He stated that he only communicated with Nakamoto online and was unaware of their true identity.
Why It Matters: Finney’s foresight in recognizing the potential of zero-knowledge proofs is impressive. As the crypto industry delves deeper into privacy and scalability issues, Finney’s early work becomes increasingly relevant.
