Bitcoiner drops BitVM paper — bringing Ethereum-like contracts to Bitcoin

The author of the white paper, Robin Linus, based BitVM’s architecture on Ethereum’s optimistic rollups with fraud proofs and recent Merkle tree developments.

A Bitcoin developer has proposed a new way to bring more expressive off-chain smart contracts to Bitcoin (BTC) without needing a soft fork.

Announced in an Oct.9 white paper titled “BitVM: Compute Anything on Bitcoin” by ZeroSync’s project lead Robin Linus, BitVM enables Turing-complete Bitcoin contracts without altering Bitcoin’s consensus rules.

A Turing Complete system is one which can theoretically provide an answer to any computational problem.

With BitVM, the “logic” of Bitcoin contracts would be executed off-chain but verification would be made on Bitcoin — similar to Ethereum’s optimistic rollups.

BitVM’s architecture is based on fraud proofs and a challenge-response model where a “prover” can make claims and a “verifier” can perform a fraud-proof to punish the prover when false claims are made.

Linus explained that Bitcoin, in its current form, is limited to basic operations, such as signatures, timelocks, and hashlocks — but that can now be broadened with BitVM, which Linus says can compute a host of interesting applications.

“Potential applications include games like Chess, Go, or Poker, and particularly, verification of validity proofs in Bitcoin contracts.”

“Additionally, it might be possible to bridge BTC to foreign chains, build a prediction market, or emulate novel opcodes,” said Linus.

Linus said a limitation of the model is that it is limited to a two-party setting with a prover and a verifier and that a significant amount of off-chain computation and communication is needed to execute programs.

Linus said the next “milestone” is to fully implement the BitVM in addition to Tree++ — a high-level programming language to write and debug Bitcoin contracts.

BitVM is enabled by the Taproot soft fork which took place in November 2021.

Linus cited Ethereum research into optimistic rollups and a study on Merkle Trees in contributing to the eight-page white paper.

Bitcoiners respond to BitVM

Prominent Bitcoiner Eric Wall posted on X (Twitter) that the concepts outlined in the BitVM white paper “check out” and is “cautiously excited” to see what real-world experiments stem from it.

Bitcoin analyst Dylan LeClair is also impressed with BitVM’s white paper. But Adam Back, a Bitcoin Core contributor suggested that people shouldn’t get too excited about the development just yet.

One builder in the blockchain space, “dotta,” noted that there is already a proof-of-concept on GitHub.

Another X user, Sam Parker, attempted to resolve a common fear among Bitcoin maximalists by explaining that BitVM won’t force Bitcoin’s to be “locked” into these contracts.

“Finally, this is opt-in. If you don’t trust your coins being locked to some Turing complete contract (totally reasonable) then don’t lock them to a Turing complete smart contract. One of [the] beauties of the UTXO system is security sandboxing.”

Others, such as “psage” say BitVM adds to the list of things that will push Bitcoin’s price forward in the next bull market.

Cointelegraph contacted Linus for comment but did not receive an immediate response.

Ordinals protocol sparks debate over NFT’s place in the Bitcoin ecosystem

The community has been divided as to whether the NFT-like "digital artifacts" are the right fit for the Bitcoin ecosystem.

The recent launch of a nonfungible token (NFT) protocol on the Bitcoin mainnet has the crypto community divided over whether it’ll be good for the Bitcoin ecosystem. 

The protocol, referred to as “Ordinals,” was created by software engineer Casey Rodarmor, who officially launched the program on the Bitcoin mainnet following a Jan. 21 blog post.

The protocol essentially allows for the Bitcoin version of NFTs — described as “digital artifacts” on the Bitcoin network.

These “digital artificats” can comprise of JPEG-like images, PDFs, video and audio formats.

The introduction of the protocol has the Bitcoin community divided however, with some arguing that it would offer more financial use cases for Bitcoin, while others say its straying away from Satoshi Nakamoto’s vision of Bitcoin as a peer-to-peer cash system.

Bitcoin bull Dan Held was one of those on board with the development, noting that it would drive demand for block space, and thus fees, while bringing more use cases to Bitcoin.

Some have pointed out that these NFT-like structures have taken up block space on the Bitcoin network, which could drive up transaction fees.

Among those include “Bitcoin is Saving” on Twitter, suggesting to its 237,600 followers on Jan. 29 that “privileged wealthy white” people’s desire to put JPEGs as status symbols may exclude marginalized people from participating in the Bitcoin network.

Cryptocurrency researcher Eric Wall disagreed with the opinion that the in-built block size limit will prevent a rise in transaction fees.

Others, such as Blockstream CEO and Bitcoin core developer Adam Back wasn’t happy with meme culture being brought to Bitcoin, who suggested the developers to take the “stupidity” elsewhere:

However, Ethereum bull and host of The Daily Gwei Anthony Sassano took a shot at the Blockstream CEO for wanting “undesirable” transactions to be censored — which many believe goes against the ethos of Bitcoin:

In a blog post, Rodarmor explained that the NFT-like structures are created by inscribing satoshis — the native currency of the Bitcoin network — with arbitrary content.

These inscribed satoshis — which are cryptographically represented by a string of numbers — can then be secured or transferred to other Bitcoin addresses, according to notes in Ordinal’s technical documentation:

“Inscribing is done by sending the satoshi to be inscribed in a transaction that reveals the inscription content on-chain. This content is then inextricably linked to that satoshi, turning it into an immutable digital artifact that can be tracked, transferred, hoarded, bought, sold, lost, and rediscovered.”

The inscriptions take place on the Bitcoin mainnet, no sidechain or separate token is needed, the document states.

It appears that only 277 digital artifacts have been inscripted thus far, according to the Ordinals website.

Interestingly, Rodarmor — admitted in an Aug. 25 interview on Hell Money Podcast that Ordinals was created to bring memes to life on Bitcoin:

“This is 100% a meme-driven development.”

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.

Lehdonvirta’s name has been suggested as a potential Nakamoto due to his early research on digital currencies and online marketplaces. However, there is no concrete evidence linking him to the creation of Bitcoin, and Lehdonvirta himself has denied being Nakamoto. He has also been involved in various policy-making processes and has provided expert testimony on digital economy-related issues to governments and international organizations.

Tucker Carlson outlines wild theory to explain Bitcoin price rise: ‘Maximum tin foil’

Members of Crypto Twitter were quick to mock Tucker Carlson, who provided no supporting evidence to back his claims.

Controversial Fox news television host Tucker Carlson has proposed a curious conspiracy theory that seeks to link airline delays in the United States and Canada with a surge in the Bitcoin price.

He suggested the computer outage behind the widespread delays may have been caused by ransomware and theorized the US Government may have bought a large amount of Bitcoin to pay the ransom.

However he did not provide any evidence for his claims.

Speaking on his “Tucker Carlson Tonight” segment of Fox News on Jan. 17, Carlson argued that the Bitcoin (BTC) price increased 20%+ soon after the U.S. Federal Aviation Administration (FAA) confirmed the disruption on Jan. 11:

“Almost all ransoms like this are paid in Bitcoin. So if the US government was buying huge amounts of Bitcoin in order to pay a ransom, Bitcoin prices would surge, of course. So the question is has that happened? Well yes, it has happened.”

“Since the nationwide ground stop last Thursday the price of Bitcoin has shot up about 20%. Is that a coincidence?” he added.

While Tucker’s fanbase online appears to believe the theory is plausible, it was less well received by the crypto community. Nick Almond, the founder of FactoryDAO described Tucker’s wild theory as “maximum tin foil” to his 13,500 Twitter followers:

Almond replied to supporters of the theory that he doubted very highly that the U.S. government would buy billions in Bitcoin on the open market to pay for the ransoms.

Blockstream CEO and cypherpunk Adam Back also mocked Carlson to his 506,000 Twitter followers in stating that the two events were exactly what Carlson described them to be — a coincidence:

Other arguments made against the theory on Crypto Twitter included that the US government already has a large amount of confiscated Bitcoin, that it would buy it OTC if it did buy it, and as Bitcoin is traceable and transparent, large ransoms are more likely to be paid in Monero.

Stack Hodler pointed out to his 30,000 followers that the recovery of $5B in assets by FTX was a more likely explanation for the recovery in crypto markets:

More than 1,300 flights were cancelled with an additional 10,000 flights being delayed in the first two days of the disruption.

The FAA stated on Jan. 11 that the disruption was caused by a “damaged database file” in its Notice to Air Mission (NOTAM) system, which they said was not wasn’t inflicted by a cyber attack.

The issue has reportedly been fixed and most flights have since resumed normal operations.

Crypto Stories: Dr. Adam Back shares his life of hacks

A cartoon version of Dr. Adam Back recounts stories of hacking coded doors at university and the inception of Hash Cash in the latest of Cointelegraph Crypto Stories.

It’s been a life of hacks for Dr. Adam Back, the CEO and co-founder of Blockstream. One of the few people quoted on the Bitcoin Whitepaper, hacking highlights of Back’s life are brought to life in the latest animated Crypto Story from Cointelegraph’s video team. 

Over a game of Jenga in a park, Back told Cointelegraph that he’s always had a “kind of security mindset.” From his days as a student, he tinkered with door codes, pin pads and locks, testing out code and gaining access to places he “wasn’t supposed to have access to.”

Back talks through the creation of Hash Cash, one of the early attempts at digital money. He uses the “Birthday collision” as an allegory for hash functions, demonstrating his aptitude to breaking down complex functions into intelligible language:

“If you have a room full of people at a party or something, there's a question which is how many people need to be in the room before there's 50/50 chance that there are two people with the same birthday.”

He explains that while people would expect the outcome to be related to the number 365–because of how many days there are in a year, the reality is far lower. This line of thinking, combined with an understanding of spam email, led to Back’s coding up of Hash Cash.

Bitcoin stands on the shoulders of Hash Cash, but Bitcoin caught on because Bitcoin ˙as a high level of decentralization, vital for the cryptocurrency’s success. Back adds that Bitcoin is also “Understandable at lots of different levels, right?”

“You can understand it from a user level or from an economics level. It's surprisingly complex to fully appreciate all of it, including the game theory and things like that.”

The cartoon interview comes to a close with a reference to Blockstream’s decision to beam Bitcoin into space and an affirmation that there will be “More Bitcoin,” from one of the Bitcoin economy’s OGs.

Blockstream raising funds for mining at 70% lower company valuation

CEO Adam Back said the fresh funding will be invested into expanding the firm’s mining capacity.

The depths of a bear market may not be the best time to raise funds but that is exactly what Blockstream is doing.

The crypto infrastructure firm is seeking fresh funding, but at a much lower valuation than previous rounds, according to a Dec. 7 Bloomberg report.

Blockstream was valued at $3.2 billion when it held its last Series B funding round raising $210 million in August 2021. Today that valuation may have fallen almost 70% to below $1 billion according to the report.

The company, founded in 2014, has raised a total of $299 million in funding over four rounds, according to CrunchBase.

Blockstream CEO and cryptographer Adam Back did not share details of the latest funding round but did reveal that the capital will be invested into expanding the firm’s mining capacity.

“We rapidly sold out all of the capacity and have a big backlog of existing and new customers with miners seeking large-scale hosting with us.”

The firm is working with Jack Dorsey’s Block (formerly Square) to develop a solar-powered Bitcoin mining facility. The mining farm will have 3.8 megawatts (MW) of electrical capacity using Tesla’s solar technology and its Lithium-ion 12 MWh ‘Megapack’, as reported by Cointelegraph in April.

Back acknowledged that BTC prices and mining profi tability were down but added “hosting rates have risen over the last quarters and our mining services are a rapidly expanding, high-margin enterprise business for us.”

Bitcoin miners are currently suffering a triple whammy of high hash rates and difficulty, high energy prices, and low BTC prices. This has caused profitability, or hash price, to fall to near-record lows of around $0.064 per TH/s per day, according to Hashrate Index.

In its monthly newsletter on Dec. 5, Blockstream revealed that its Blockstream Mining Note (BMN) token has earned around 5.37 BTC cumulatively in returns nearly halfway into its three-year term.

BMN is an EU-compliant security token that provides qualified investors access to Bitcoin hash rate at the firm’s U.S. enterprise-grade mining.

The firm has also been promoting a new limited edition ‘Jade Transparent’ hardware wallet claiming that it is “hodling our Bitcoin into the 2090s and beyond.”
