Kathleen and Arthur Breitman are crypto royalty. The husband-and-wife team created Tezos, an early leader in the “second generation” of blockchains, and are the authors of an influential series of essays on crypto governance.
In 2016, the pair raised an eye-popping $232 million for Tezos in an initial coin offering, putting the project—which was among the first to incorporate now-familiar crypto concepts like proof-of-stake—in a position to lead the crypto industry. But then something happened: the blockchain built by the Breitmans fumbled its early lead and Tezos was surpassed by Ethereum and other rivals that offered similar features.
Once near the top of cryptocurrency price rankings, Tezos’ XTZ token sunk this year to number 40, far behind novelty coins like Doge and also-rans from the first generation of crypto.
Now, Tezos is in a fight for relevance—as Kathleen herself acknowledges. “There are thousands of blockchains but the ones that matter will be ‘winner take most’ with the top three taking 90% of the market,” she says.
Can Tezos make a comeback? Skeptics think the window may have closed as Ethereum consolidates its dominance, and as newer projects like Solana climb up the crypto charts. But the Breitmans, who are resuming a more active role after leaving the guidance of Tezos to others, argue the real competition for blockchain dominance is just beginning.
The first couple of blockchain
The Breitmans are in their thirties, but come across as long-tenured academics. Arthur is French with a world-weary affect and can describe any aspect of blockchain, no matter how technical, with quick precision. Kathleen, who grew up in New York City, is equally versed in crypto but likes to spice up her accounts with gossip and droll anecdotes. The pair met at Cornell where their mutual passion for polymath study led them to marriage and to the blockchain project that made them minor celebrities.
The Breitmans first published their vision for Tezos in 2014, five years after Satoshi introduced Bitcoin to the world. By this time, Bitcoin’s potential had become clear—the currency crossed the once-unthinkable $1000 mark in late 2013—but so too had its drawbacks. Those include a congested network, limited features, and an unruly governance structure that makes significant reforms nearly impossible.
The Tezos blockchain promised to overcome these problems. One of the first of a “second generation” of blockchains—Ethereum and Polkadot are among the others—the Breitmans’ blockchain promised a more efficient way to process transactions through a now familiar mechanism called proof of stake. It also touted a version of smart contracts, which made Tezos infinitely more versatile than Bitcoin, and a democratic governance structure that allowed token owners to vote on changes to the network. This voting system also introduced a novel delegation idea called staking that has since been imitated by other blockchains.
Tezos also stood out because its creators, unlike other blockchain builders, didn’t attempt to cultivate larger-than-life personas or embrace the weirder fringes of meme culture. Arthur, especially, has a distaste for hype—even if that puts him at odds with the broader crypto community.
“I don’t want to be part of that thought leadership crap," he says. "I like nuance. But people don’t want nuance, they want charismatic leaders."
Shunning the cult-of-personality aspect of the crypto scenes, the Breitmans worked on building out their vision for a new type of blockchain and attracted high profile supporters, including the venture capital firm Andreessen Horowitz, which published several of their papers in its “crypto canon” of essential reading.
They also raised money. A lot of it. Amid the crypto hype cycle of 2017, Tezos conducted one of the biggest initial coin offerings of all time, raising $232 million, a good portion of which is still parked in the project’s eponymous foundation.
Then came trouble. Shortly after the ICO, the Breitmans became enmeshed with a slippery European they hired to run the Tezos Foundation but who they say engaged in self-dealing at the expense of Tezos. This led to a bitter legal fight and a delay in the launch of Tezos’ real-life blockchain that triggered new lawsuits from frustrated token buyers.
The Breitmans ultimately prevailed, leading Wired to place them on its cover with the caption “The Blockchain: a love story, a horror story.” (Kathleen gripes that the photos made them look cadaverous.) By 2018, Tezos blockchain had evolved from concept to a live blockchain, achieving the crypto world’s ideal of a global ledger maintained by a decentralized community.
Having accomplished their dream, the Breitmans moved on to other projects, including a Magic the Gathering style video game that lets players use blockchain to store cards and other digital artifacts.
But somewhere amid all this progress, Tezos lost steam. The value of its tokens began to slide as Ethereum became the dominant smart contract blockchain, and newer projects like Uniswap and Solana enjoyed the hype once lavished on the Breitmans’ creation. On Reddit and other social media platforms, crypto watchers began to ask if Tezos had become a “ghost chain”—a working blockchain with few real world users.
“It felt like it had a large lead initially as one of the older Layer 1 blockchains out there, and had lots of momentum going into 2020. Now it seems like they’re stuck in place,” says Wilson Withiam, an analyst with crypto research firm Messari, who describes Arthur and Kathleen as “brilliant” but questioned whether their creation will last.
Why did Tezos stumble?
The lawsuits are the most obvious explanation for Tezos’s fading star. The legal fight for control of the blockchain, in particular, created distraction and delays and took an emotional toll on the Breitmans—Kathleen notes the pandemic has been easy by comparison.
“We already went through the shittiest version of being alone together when we were being sued,” Kathleen says dryly.
But while the legal drama hurt Tezos’ momentum, it’s not the only reason for the project’s stumbles. The blockchain has also been hindered by a lack of developers—the people who build infrastructure and applications, and who are essential to turn a software protocol into a thriving eco-system.
A lack of developers implies a lack of users and, in the case of blockchains, the risk a project will turn into software’s version of a desert. Arthur acknowledges some came to view Tezos this way.
“Back in the spring, Ethereum talking heads were saying ‘Tezos is a ghost chain,’” he notes, but points to a recent uptick in activity on the blockchain to say the claim is unfounded, and that the project has turned a corner.
Still, the challenge over attracting developers persists, especially as Tezos must compete not just with the likes of Bitcoin and Ethereum, but with a host of flashy newer projects like Cosmos and Avalanche.
Adding to the challenge in luring developers is the fact Tezos is written in OCaml, a programming language developed by top coders and the government of France.
Tezos’ technical barriers have slowed its growth but so too did another of its distinctive features—its governance process. That process is designed to be transparent and democratic, but it is also slower than what occurs at other blockchains, where big decisions are typically pushed through by a small clique of insiders.
Ironically, Tezos may have paid a price for achieving decentralization, which is the highest ideal in crypto circles, but which is more often carried out in lip service than in actual practice.
“They did a nice job of holding true to the ethos of decentralization but, when it comes down to it, how much decentralization do users actually want? That’s where the governance process, as interesting as it is, played to their detriment,” observes Messari’s Withiam.
Withiam notes that newer, more centralized rivals like Solana and Binance have been able to experiment more, and have rolled out major new features in days or weeks—features that would take Tezos, with its meticulous governance process, months or more to push through.
Defying the DeFi Trend
Tezos’s slow response to new crypto trends was evident when it came to decentralized finance or DeFi, the Lego-like stack of applications that has become the biggest blockchain story of the last two years. The primary beneficiary has been Ethereum, where investors have parked hundreds of billions of dollars in DeFi smart contracts, but Binance, Solana and others have partaken in the boom too.
Tezos, however, sat out the DeFi trend until last month when it launched a modest feature called “liquidity baking” that lets users deploy smart contracts and earn Tezos's token XTZ if they put Tezos or a synthetic version of Bitcoin in a liquidity pool. The move was a grudging acknowledgement by Tezos of DeFi’s relevance—though Kathleen and Arthur maintain the phenomenon is overblown.
“A lot of DeFi projects are going to age like old milk,” says Kathleen, who has special contempt for yield farming—a DeFi phenomenon in which new blockchain projects hand out bonus tokens to those willing to place its other tokens in a liquidity pool. She says yield farming often amounts to a hustle by projects that don’t have any purpose or, worse, are retreads of earlier flops.
“You get all of these use cases from 2015 dusted off and repackaged," she says bitterly. "They claim it's different because it will have a yield-per-week component. ‘But now with yield farming!'"
Arthur is more measured. He views yield farming as a novel fund-raising mechanism that lets new blockchain projects raise capital without turning to traditional investors or to airdrops, which hand out tokens indiscriminately in the hopes people will trade them. But he also warns many yield farming initiatives are empty shells to promote tokens that don’t serve any purpose.
Some of this might sound like sour grapes given that Tezos missed out on the DeFi boom. But the Breitmans aren’t sour towards rivals like Sam Bankman-Fried ("SBF"), The founder of crypto exchange FTX who became crypto’s hottest celebrity of 2021 in part because of the fortunes he made on DeFi.
“With SBF, there's a lot of, 'Damn, that was a good idea,’” says Kathleen. “He's not putting people down, he’s kind of a happy warrior, which makes you want to root for him.”
Maybe so, but SBF’s success and that of Solana, which he has backed, means a further obstacle to Tezos reemerging as a leading blockchain—especially if, as the Breitmans themselves believe, only two or three blockchains will come to dominate crypto in the future.
Kathleen describes herself and Arthur as "grizzled" and says their experience gives them staying power.
Grizzled is an odd way to describe someone who is barely 30, but in a crypto sector that’s just a decade old and full of fresh-faced founders, she may have a point. The Breitmans claim their trials over the last five years leave Tezos in position to win the blockchain race.
The pair claims that the foundations of Tezos are sounder than those of rival blockchains, and that this is something others are beginning to notice.
It’s not an idle claim, as several big brands have embraced Tezos in recent months. Those include Red Bull and McLaren Racing, which are using the blockchain for fan experiences, as well as gaming giant Ubisoft, which is testing Tezos for new video game experiences.
And if Tezos sat on the sidelines for the DeFi boom, it is carving out a major role for itself in a newer crypto mega-trend: the frenzy over non-fungible tokens (NFTs), which let people own unique blockchain-stamped digital artifacts like art or sports highlights.
While most NFT action still happens on Ethereum, Tezos is home to a major NFT marketplace known as “hic et nunc.” The forum was launched by a Brazil developer who received a small grant from the Tezos Foundation, which has been sprinkling money on projects across the globe and finally hit pay dirt.
The blockchain’s NFT reputation gained a further boost when the American music star known as Doja Cat chose OneOf, another Tezos-backed forum, to issue her first NFT. She said her choice was based on environmental concerns since the blockchain doesn’t depend on energy-intensive mining like Ethereum.
Kathleen said in a recent Forbes profile that the Breitmans didn’t conceive of Tezos as a green project—but that she is glad it's gaining that reputation. Tezos’ emergence as an NFT magnet is thus partly a function of luck, but perhaps luck the Breitmans deserve after their blockchain’s earlier misfortunes.
In any case, the flurry of NFT activity has helped Tezos notch a more than 1,000% gain in network activity from last year. And on the Doja Cat news, the price of Tezos’ XTZ token took off, helping it climb back into the top 30 on token leader boards.
Meanwhile, Tezos has taken a major step to address its developer problem. It has decided to branch out from the rarified world of OCaml, and test software development tools in the everyman RUST programming language.
As for the Breitmans, they have taken on a more active role in shepherding their creation. After basically stepping away, Arthur has taken a board seat on the Tezos Foundation—a well-funded group that critics say became a magnet for people looking for plush jobs that demanded little in the way of work or results. In recent months, a person familiar with the group’s activities say Arthur has “cleaned house.” Kathleen has returned to her role of blockchain’s version of a public intellectual, publishing essays and, of course, advocating for Tezos.
The Breitmans’ renewed attention has been a welcome development for the project’s beleaguered token holders, but is no guarantee that Tezos will emerge as a long-term winner amid an increasingly crowded field of blockchains. Despite the project's recent momentum, Tezos still risks forever playing catch-up.
Kathleen is unfazed by such predictions. She argues that as the blockchain industry matures, the winners will be defined by the technical merits, and that this will see Tezos reclaim its role at the front of the pack.
“Chains have been driven by the myth and ethos around them, not the technical differentiation,” she says. “We’re all driving model Ts and someone is going to come along with a Ferrari."
She didn’t say whether it will be the Breitmans or someone else who builds that Ferrari.
