Bitcoin pioneer Hal Finney talks zk proofs in 25-year-old unearthed footage

A recently resurfaced video shows Hal Finney discussing the possibility of zero-knowledge proofs at an annual cryptology conference in California some 25 years ago.

Early Bitcoin (BTC) pioneer Hal Finney shared his vision for zero-knowledge proofs more than 25 years ago, a full decade before the launch of the first cryptocurrency, Bitcoin. 

The video, purportedly from the Crypto ‘98 conference held on Aug. 26, 1998, in Santa Barbara, shows Finney discussing in detail, the concept of zero-knowledge proofs — a cryptographic technology that gained immense popularity decades later.

Finney explains how one could hypothetically perform a zero-knowledge proof on a SHA-1 hash, describing the possibility of sending a cryptographically encrypted claim without revealing any of the details contained within the same claim.

“I want to prove to you that I know a message that hashes to a given hash value using the SHA-1 hash. I don't want to reveal anything about the message to you. It's a zero-knowledge proof, and I've written a program to do this that I'll tell you about,” explained Finney.

A zero-knowledge (ZK) proof is a cryptographic protocol that enables one user (the prover) to convince another (the verifier) that a particular claim is true without disclosing any details about the claim itself.

At the time of Finney’s speech, zero-knowledge proofs were considered to be a possibility, but due to hardware limitations at the time were widely regarded, as Finney puts it: “inefficient or impractical.”

Decades later, the crypto industry is now abuzz with discussions and debates on how best to implement zero-knowledge proofs, with the main use of the technology being leveraged to scale the Ethereum network.

Finney is a storied pioneer of the cryptocurrency industry. He was a computer scientist who made some of the earliest contributors to privacy-enhancing technology, including the first fully anonymous re-mailer, a tool that protected user identity when sending emails. Additionally, Finney created the first reusable Proof of Work system, which preceded Bitcoin by nearly five years. 

In 2009, Finney was the very first recipient of Bitcoin, after he was transferred 10 BTC by the cryptocurrency’s pseudonymous founder Satoshi Nakamoto, and was known to have worked closely with Nakamoto in Bitcoin's earliest days. 

Some have speculated that Finney could be Satoshi Nakamoto himself, though he has denied the theory.

Finney was diagnosed with a rare neurological disease known as ALS, the complications of which would later claim his life in 2014. Finney was cryopreserved by the Alcor Life Extension Foundation in Arizona.

The video could be one of the first times that some people has been able to hear Finney’s voice, suggested TrustMachines on X.

7 people who could be Bitcoin creator Satoshi Nakamoto

To this day, the exact identity of Satoshi Nakamoto remains a mystery.

Satoshi Nakamoto is the pseudonym used by the creator(s) of Bitcoin, whose true identity remains unknown. The name was used to author the original Bitcoin (BTC) white paper in 2008 and to create and deploy the first Bitcoin software in 2009. Nakamoto’s true identity has never been revealed, and they have remained an enigma in the world of cryptocurrency. They are estimated to have mined around 1 million BTC in the early days of the network, which would make them one of the wealthiest people in the world.

Some believe that Satoshi Nakamoto is a pseudonym for an individual, while others maintain that it could be a group of people. Below is a list of people believed to be the best possible candidates for the creator, with some having already refused or embraced the identity.

Nick Szabo

Nick Szabo is a computer scientist, legal scholar and cryptographer known for his research on digital contracts and digital currency. He is credited with developing the concept of smart contracts, which are self-executing contracts with the terms of the agreement written into the code. Szabo first proposed the idea of smart contracts in 1994 in an article titled "Smart Contracts: Building Blocks for Digital Markets.”

Szabo is also known for his work on digital currency and cryptography and is considered a pioneer in digital money. He created a precursor to Bitcoin called “Bit Gold,” which he described in a series of blog posts in the late 1990s.

Szabo is considered by many to be a likely candidate for the true identity of Nakamoto, but he has denied it.

He is also a legal scholar and has written extensively on the legal implications of digital contracts and digital currency. He is an advocate of digital freedom and privacy and has written on the intersection of cryptography and civil liberties.

Hal Finney

Hal Finney was a computer programmer and early Bitcoin contributor. He was one of the first people to run the Bitcoin software and was an active member of the community in the years following its creation. Finney was also a developer of the Pretty Good Privacy (PGP) encryption software, which is widely used to secure email communications.

He was a well-known figure in the Bitcoin community and was recognized for his contributions to its development. He was also a vocal advocate for Bitcoin and wrote extensively on the technology’s potential in various forums and social media platforms.

Finney denied the claims that he created Bitcoin but acknowledged having received the first Bitcoin transaction from Nakamoto. He passed away in 2014 due to complications from amyotrophic lateral sclerosis, a degenerative disease of the nerve cells in the brain and spinal cord that control muscle movement. He was widely respected and honored within the Bitcoin community.

Dorian Nakamoto

Dorian Nakamoto is a retired Japanese-American engineer and physicist whose name was put forward as a potential Satoshi Nakamoto in a 2014 article by Leah McGrath Goodman in the magazine Newsweek.

Dorian Nakamoto denied the allegations, stating that he had never heard of Bitcoin before the article was published and that he had no involvement in creating the cryptocurrency. He also said he was not fluent in English and felt that the interviewer had taken his statements out of context.

Despite his denial, the article sparked a media frenzy, with journalists and members of the public staking out Dorian Nakamoto’s home and attempting to contact him for interviews. The attention caused a great deal of stress for him and his family, and he later sought legal advice to deal with the situation. Dorian Nakamoto’s name was later removed from the list of potential candidates. He has been a private person since then, and not much is known about him or his activities.

Craig Wright

Craig Wright is an Australian computer scientist and businessman who has publicly claimed to be Nakamoto. Wright first made the claims in 2016 and later provided some technical evidence to support them.

Wright has been a controversial figure in the cryptocurrency community, and his claims to be Nakamoto have been met with great skepticism. Many experts in the field have stated that the evidence presented by Wright is insufficient to prove his claim, and some have accused him of fraud.

Wright is also known for his involvement in various lawsuits and legal disputes, including a multibillion-dollar lawsuit against the estate of Dave Kleiman, a computer scientist and cybersecurity expert who was also considered a potential candidate for Nakamoto, and several conflicts with other members of the cryptocurrency community.

Adam Back

Adam Back is a British computer scientist and cryptography expert who has been involved in developing various blockchain and digital currency projects. He is best known as the creator of Hashcash, a proof-of-work system used to prevent spam and denial-of-service attacks, which was proposed in 1997 and later served as an inspiration for Bitcoin’s mining mechanism.

Back is a respected figure in the blockchain and cryptocurrency industry and has been involved in various projects and companies. He is also an active member of the cypherpunk community, a group of activists and technologists who advocate for using cryptography to protect privacy and civil liberties.

Back has denied being Nakamoto but remains a vocal advocate for privacy and has spoken out against government surveillance and the erosion of civil liberties. He is also known for his research on distributed systems, writing several papers and articles on the subject.

Wei Dai

Wei Dai is a computer scientist and cryptographer known for his contributions to the development of digital currency. He is best known for his work on digital cash and electronic payment systems and is considered one of the field’s pioneers.

Dai’s most notable contribution is the creation of B-money, an anonymous, distributed electronic cash system proposed in 1998. The concept of B-money served as an inspiration for the development of Bitcoin, and many of the ideas presented in Dai’s B-money paper were later incorporated into the Bitcoin white paper.

Dai has denied being Nakamoto. He remains a member of the cypherpunk community.

Vili Lehdonvirta

Vili Lehdonvirta is a Finnish economist and researcher on digital culture and economies. He is a senior research fellow at the Oxford Internet Institute of the University of Oxford, where he researches digital labor, platform economies and digital currencies. Lehdonvirta has published several papers and articles on digital currencies and online marketplaces and has been a speaker at various conferences and events on the topic.

Crypto Twitter Speaks Up for Hal Finney’s Account, SBF Was Reportedly Told by Binance CEO: Stop Causing ‘More Damage’ — Bitcoin.com News Week in Review

Crypto Twitter Speaks Up for Hal Finney’s Account, SBF Was Reportedly Told by Binance CEO: Stop Causing ‘More Damage’ — Bitcoin.com News Week in ReviewBitcoiners on Twitter recently pleaded with the CEO of the social media platform, Elon Musk, to preserve the account of late computer scientist and bitcoin pioneer Hal Finney. The outcry came after Musk announced that a mass of inactive accounts would be purged. Finney’s wife has since jumped in, and tweeted from Hal’s former account […]

Hal Finney’s wife resumes activity on Bitcoin pioneer’s Twitter account to avoid potential purge

Under Elon Musk’s leadership, Twitter suspended a number of accounts including those controlled by high-profile journalists and social networking platform Mastodon.

Fran Finney, the wife of computer scientist Hal Finney — the recipient of the first transaction on the Bitcoin blockchain from Satoshi Nakamoto — reactivated her late husband’s Twitter account amid concerns Twitter CEO Elon Musk might purge the content from the social media platform due to inactivity.

Many Crypto Twitter users reported on Dec. 16 that Finney’s account registered activity for the first time in more than 12 years. Some speculated that a hacker might have taken control of the Bitcoin (BTC) pioneer’s account and it’s more than 71,000 followers, but Fran quickly stepped in to dispel rumors.

“I am tweeting for Hal [...] to avoid his account being purged by Elon,” said Fran.

It’s unclear whether Fran Finney’s intervention may save the crypto pioneer’s social media presence. Amid Musk’s $44-billion purchase of Twitter which was completed in October, he claimed he backed free speech as “the bedrock of a functioning democracy.”

However, under Musk’s leadership, the social media platform on Dec. 15 purged a number of accounts controlled by high-profile journalists at institutions including CNN, the New York Times, and the Washington Post. Accounts tracking the movements of Musk’s private flights as well as promoting social networking platform Mastodon — which has attracted many Twitter users following the billionaire’s takeover — were also suspended. The Twitter CEO claimed the former “doxxed my exact location in real-time.”

Musk had a net worth of more than $300 billion in October 2021 before the acquisition of Twitter, and around the same time, the price of Tesla stock reached an all-time high of $407.36 in November 2021. In roughly a year, the Bloomberg Billionaires Index showed that the Tesla CEO had dropped to the second richest person on the planet, with a reported net worth of $169 billion at the time of publication.

As CEO, Musk oversaw a number of controversial decisions at Twitter that had many in the business world questioning his acumen. He fired many top executives, including many members of the platform’s content moderation team, and attempted to charge users for “verified” blue check marks — leading to many fake accounts with a veneer of legitimacy. The social media platform also saw a spike in tweets containing hate speech and vaccine misinformation, putting revenue from advertisers at risk.

Twitter users seemed to largely support Fran Finney’s efforts to show the account was still active and beneficial to the crypto community. Former Twitter CEO Jack Dorsey also chimed in on the platform to express his surprise over the account’s reactivation.

“There should be a way of safeguarding accounts of historical significance,” said Twitter user 0xAphelion on Hal Finney’s account. “But better to be safe.”
