One of the oldest and most significant projects built on the Ethereum blockchain, Augur, has become the focus of a heated dispute. The controversy arises from allegations brought by one founding member against four other key participants.
A historic project
Three years ago, Augur — a decentralized prediction market protocol running on the Ethereum blockchain — held one of the earliest initial coin offerings (ICOs), long before this funding mechanism was widespread. Between August 7 and September 5, 2015, the team issued 8.8 million reputation tokens (REP), with a maximum supply capped at 11 million. Each token was sold for less than $0.60, and the sale raised over $5 million.
With a small team, Augur created a decentralized protocol in which event outcomes could be estimated peer-to-peer and participants were rewarded with tokens for accurate reporting. In practice, the platform enables market-style wagers on any measurable outcome while avoiding centralized intermediaries or government gatekeepers. The mechanism can also serve as a form of insurance: for example, a farmer could hedge against unlikely weather events that would ruin a harvest. If that unlikely event occurs, those who bet on the opposite outcome would lose and the farmer’s position would pay out, effectively providing compensation to cover the loss.
Substantial gains for ICO participants
Within three years of the ICO, REP briefly traded as high as $100, meaning early investors could have seen returns of up to 200x their initial investment. Augur grew to about 15 developers, designers and researchers and worked with the design firm IDEO on a beta interface. Advisors included Ethereum co-founder Vitalik Buterin and Elizabeth Stark, co-founder of Lightning Labs. The community targeted a mainnet launch for July 2018, which many in the industry viewed as one of the most compelling real-world use cases for blockchain technology.
Claims by the excluded member
Amid public attention, one early team member remained largely visible only in legal filings. In a civil lawsuit, Matthew Liston, 26, sued four Augur associates. Liston alleges that angel investor Joseph Ball “Joe” Costello, 64, and three other founders — Jack “John” Peterson, 35; Joseph Charles “Joey” Krug, 22; and Jeremy Gardner, 26 — committed fraud, breach of contract, and misappropriation of trade secrets related to his ouster from the company and his exclusion from the allocation of Augur tokens.
The complaint also alleges that after his termination, Liston was coerced into signing agreements containing terms Peterson later violated. Liston claims Augur failed to honor a promise to recognize him as a co-founder, denying him the professional recognition he expected in the industry. The complaint states:
“Ironically, Matthew Liston suffered reputational harm.”
In addition to the core team, the original Bay Area corporate entity, Dyffy, Inc., was named as a defendant for allegedly failing to pay wages owed to Liston. The complaint also names two entities associated with the Forecast Foundation — one registered in Oregon and one in Estonia — alleging they conducted business illegally in California, processed the initial ICO, and improperly appropriated Liston’s interests from Dyffy.
According to the filing, Peterson, Gardner and Costello carried out a hostile takeover of Dyffy, with Gardner serving as president and Peterson as secretary of the dissolved Oregon non-profit. All of them, except Costello, allegedly retained equity stakes in the for-profit Estonian entity, with Peterson in a leading role.
Large damages sought
At the time of filing, the market capitalization of REP stood at about $455 million. Liston sought $38 million in general damages and $114 million in punitive damages, totaling $152 million — more than a quarter of REP’s market cap. If sustained, this would represent one of the largest individual private lawsuits in cryptocurrency history, surpassing many prior suits against exchanges and projects, although some class actions in the space have sought larger aggregates.
Joey Krug, who remains an advisor to Augur, denied the claims. “The allegations are baseless and inaccurate,” Krug said, asserting that Liston accepted cash severance from Dyffy and signed a full release. Krug added that, contrary to Liston’s assertions about his role, “there was not a single GitHub commit by Liston across Augur’s repositories. He is not an Augur founder.”
Jeremy Gardner called many of the allegations “plainly false” and described the suit as “frivolous.” The original complaint was filed on April 19 in San Francisco County and amended on May 10 to add further details. The court set a hearing for both parties in September 2018.
The plaintiff’s account
Liston’s lawsuit against Jack Peterson recounts tensions that began shortly after June 2014, when Liston incorporated the Delaware company Dyffy and hired Peterson. Liston says he intended to build a blockchain-based betting and prediction market. According to the complaint, Peterson was initially skeptical until a developer in the open-source community brought the project to his attention.
Liston alleges that after reading Paul Sztorc’s Truthcoin whitepaper, he adapted that research into the intellectual property that later formed the basis for Augur’s REP token. He claims persuading investor Costello to provide funding was key to convincing Peterson to engage Paul Sztorc. As a result, Costello was installed as a Dyffy shareholder and director, and Peterson became chief technologist under Liston’s authority, according to the complaint.
Sztorc later confirmed that Liston introduced his code and the Truthcoin concept to Jack Peterson, which led Dyffy to pursue the idea. But disputes over technical and commercial direction began within months. On October 24, 2014, Liston claims he was formally removed from the company and the board. He alleges Gardner “instigated and conspired” with Peterson and Costello in that effort.
Alleged illegitimate transfer of ownership
After Liston’s removal, Krug was installed as a director and Peterson as chief technologist, while Peterson later took the CEO role. The Oregon Forecast Foundation, a non-profit, was established on December 23, 2014. Liston claims that Peterson, Krug, Gardner and Costello then improperly transferred Augur’s intellectual property, financial assets and equity interests from Liston-owned Dyffy to the Forecast Foundation.
Liston contends the transfer was illegitimate because he retained contractual ownership within Dyffy and because the Forecast Foundation was not registered to do business in California despite Augur operating primarily from San Francisco. The complaint asserts that any transfer of Liston’s tokens, assets or equity would have required his consent.
Ongoing liabilities tied to Dyffy
Paper ties to Dyffy continued to cause problems for Liston. Even after termination, he was allegedly held responsible for a contractor claim against Dyffy seeking $15,000 for services rendered under his name. Liston claims Peterson, Krug, Gardner and Costello breached fiduciary duties by failing to secure proper corporate indemnity protections that would have allocated litigation costs appropriately among legal entities.
The complaint alleges Costello was aware of Liston’s ongoing contractual ties to Dyffy and pressured him to sign agreements releasing future claims in exchange for cash and REP tokens. Over the four months after his dismissal, Liston says Costello repeatedly pressured him by phone and text to accept a buyout that would exchange all his Dyffy shares for cash and REP.
The filing describes “a series of highly coercive, unrelenting, manipulative communications” that included abusive phone calls in which Costello reportedly shouted. From April 13 to 15, 2015, Costello allegedly issued time-sensitive ultimatums demanding Liston accept the deal or receive nothing. A text from Costello on April 14, 2015 read, “If we don’t resolve this today or tomorrow, you will get nothing.” On April 15, he added, “Two hours left.”
“If I don’t hear from you in the morning, the answer is that you’re not accepting the deal and we’ll restructure.”
“Two hours left,” Costello wrote on April 15, 2015.
Liston says he capitulated under pressure
Liston says he repeatedly asked to obtain legal advice before agreeing but lacked the financial resources to hire counsel. Facing persistent pressure he describes as “abusive,” he alleges he capitulated and signed the two agreements on April 19, 2015. Those agreements transferred 5% of the token allocation to him for $65,000 in cash, according to the complaint.
Incomplete disclosures, Liston alleges
Liston claims he later discovered the defendants had concealed specific plans for the REP token ICO and that he had been led to believe the tokens were worthless at the time of the buyout. Had he understood the true scope and potential value of the ICO, he says he would not have accepted the deal and he would have retained a larger stake. Under contract law, Liston contends the coercion he experienced should render the agreements unenforceable.
Liston argues that even if a direct token allocation was not made, the team should have transferred tokens to him on account of his Dyffy equity. He asserts that the transfer of Dyffy’s interests to Forecast Foundation OÜ in Estonia, and to the Oregon non-profit, functionally sold and redistributed Dyffy’s assets without his consent. Liston points to the equity positions retained by Peterson, Krug and Gardner as evidence of that transaction.
Denial of co-founder recognition
The suit also alleges that Peterson’s refusal to acknowledge Liston as a co-founder — despite an earlier promise — supports Liston’s claim he was misled into the release. Liston cites a message from Costello on April 16, 2015 stating that the release would make him a recognized Augur founder. Liston contends Peterson never intended to honor that term and blocked press releases and public statements that would name Liston as a co-founder when the ICO launched.
Peterson allegedly denied Liston’s co-founder status publicly in November 2015, saying, “You are not a co-founder, so no.” The complaint claims Peterson later attempted to persuade Liston’s employer at Gnosis, where Liston worked as head of strategy in 2017, to stop him from using the co-founder title. In January 2018 Peterson reportedly tweeted denial of Liston’s co-founder status and, through Forecast Foundation OÜ, sent a cease-and-desist demanding Liston refrain from claiming the title. An unnamed Augur employee also emailed Ryan John King, CEO of FOAM — an employer that listed Liston as a co-founder — seeking removal of the “co-founder Augur” line from Liston’s profile.
Allegations of harassment
Peterson has also published a different version of Augur’s origin story and portrayed Liston dismissively in public posts and tweets. The dispute has drawn criticism from members of the early community and contributors who say several early contributors were treated unfairly.
Criticism of Augur
Paul Sztorc, the author of Truthcoin’s whitepaper, has expressed sympathy with Liston and criticized how some early contributors were compensated. He noted that other early developers who contributed significant work later felt sidelined. One early contributor, who said he wrote the first minimal viable product in Python and taught the team the Truthcoin design, later launched Amoveo — a project described as an alternative market protocol without a REP token, aiming for lower operating cost and the ability to integrate with Bitcoin’s Lightning Network using oracle mechanisms.
Was Liston a “real” programmer?
Sztorc has said the team sought stronger technical leadership and that Costello once asked him what the project needed. “I said: ‘You need programmers. Matt was not a real programmer,'” Sztorc recalled. The complaint does not detail all the technical disagreements, but a source familiar with the matter said Liston preferred building on Ethereum to process predictions more efficiently, while other team members initially favored a Bitcoin-based approach. That source added that Augur ultimately migrated to Ethereum after Liston’s departure. Since leaving Augur, Liston has contributed to other Ethereum projects and worked with ConsenSys.
Peterson and Pantera Capital (where Krug was a co-investment director) remain active with Augur. Gardner founded an investment firm and previously served as an entrepreneur in residence at Blockchain Capital. Costello continues to serve on Augur’s advisory committee and runs Enlighted, Inc., a smart-building company that was expected to be acquired by Siemens in the third quarter of the year.
