From cat memes and music tracks to all manner of digital art, the bizarre, often quirky market for non-fungible tokens (NFTs) is booming. And now, science is hopping on the bandwagon for these receipts of ownership of digital files that are bought and sold online.
On 8 June, the University of California, Berkeley, auctioned off an NFT based on documents relating to the work of Nobel-prizewinning cancer researcher James Allison for more than US$50,000. On 17 June, the US Space Force — a branch of the US Armed Forces — started selling a series of NFTs featuring augmented-reality images of satellites and space iconography.
And, from 23 to 30 June, computer scientist Tim Berners-Lee, who invented the World Wide Web, is auctioning an NFT featuring the source code of the original web browser, along with a silent video of the code being typed out.
Meanwhile, biology pioneer George Church and a company he co-founded, Nebula Genomics in San Francisco, California, have advertised their intention to sell an NFT of Church’s genome. Church, a geneticist at Harvard University in Cambridge, Massachusetts, who helped to launch the Human Genome Project, is well known for controversial proposals, including resurrecting the woolly mammoth and creating a dating app based on DNA.
The fad for NFTs has been celebrated online for elevating digital art — and simultaneously derided as meaningless and for having a huge carbon footprint because of the massive computing power required to sustain it.
The arguments over NFTs in science are similarly heated, with some saying they provide an incentive to showcase science to the public; a new method of fundraising; and even a way for people to earn royalties when pharmaceutical companies buy access to their genomic data. Others say that NFTs — which operate in a similar way to digital cryptocurrencies — are just needless energy pouring into a market bubble that’s sure to burst.
“The more you look at it, the more you realize how bonkers it is,” says Nicholas Weaver, who studies cryptocurrency at the International Computer Science Institute in Berkeley.
NFTs use the blockchain technology that underlies cryptocurrencies such as Bitcoin to certify ownership of a file. NFTs are ‘minted’ in the same way as cryptocurrency — using one of many online platforms to add them to a tamper-proof blockchain ledger, typically at a cost of tens or hundreds of dollars — and then sold online. People can buy and trade these certificates in the same way as physical collectibles, such as baseball cards. The art or data can be freely viewed online and downloaded in their original form; the NFT buyer simply has a verifiable receipt of ownership.
The NFT concept was born in the early 2010s but exploded this year: in March, for example, an NFT for a digital artwork by a US artist nicknamed Beeple sold for nearly $70 million. The NFT market hit a 30-day sales record of $325 billion in early May. In June, it cooled significantly, but it is still seeing more than $10 million in sales per week.
Michael Alvarez Cohen, director of innovation ecosystem development in the intellectual-property office at the University of California, Berkeley, decided to try to use NFTs to raise funds for the university. A team of designers scanned legal papers filed with the university, along with handwritten notes and faxes relating to Allison’s valuable discoveries. This artwork, called The Fourth Pillar, is available for all to see online, and the team minted an NFT for ownership of the work.
After a short bidding war, the NFT sold on 8 June for 22 ether (around US$54,000). The buyer was a Berkeley alumni group called FiatLux DAO, founded days before by the same blockchain experts who had advised Berkeley on how to create the NFT in the first place. The money will be split between NFT auction site Foundation, a Berkeley research fund and carbon offsets.
“It’s an interesting combination of showing the world these historic documents, and also creating art and sponsoring research and education,” says Cohen. “It’s kind of a beautiful circle.”
But others counter that selling NFTs is a waste, because blockchains rely on energy-hungry computational crunching to prevent data corruption. Digital-currency operator Ethereum, for example, currently has about the same energy usage as the whole of Zimbabwe.
That makes NFTs “really a criminal amount of waste for something that doesn’t do anything valuable other than act as a database for receipts for ugly cats”, says Weaver. Auctioning off the physical papers would make more sense, he says.
Genome gold rush
The Berkeley team is also creating a digital artwork from documents relating to Nobel laureate Jennifer Doudna, one of the pioneers of CRISPR gene-editing, for a future NFT auction. That is being slowed by the need to make sure that her patent — which is still active — isn’t infringed by the art.
Meanwhile, on 10 June, Church and Nebula Genomics put up for sale 20 NFTs, each featuring an artwork based on Church’s likeness and a special, limited edition discount on Nebula’s whole-genome sequencing service. Money raised will be split between an unnamed charity, Church, blockchain company Oasis Labs, Nebula Genomics and the sales platform AkoinNFT.
That offering is a surprising step back from what was originally advertised: the group said it would be selling an NFT including Church’s genome in a 10 June auction. But that plan was put on the back burner at the last minute, Nebula Genomics told Nature, “because the NFT and crypto markets have declined over the past week”.
“Our plan is to continue to wait for market conditions to improve before launching the entire auction,” says Nebula co-founder Kamal Obbad. It is unclear when that might be.
The idea of selling an NFT of Church’s genome had provoked both excitement and bemusement online. As one scientist joked on Twitter, given that Church’s genome has long been freely available online: “By a weird coincidence, I’m also selling George Church’s genome! No auction or NFT or anything though,” they quipped, offering to send the link in exchange for $5.
But for Church’s company, this NFT has a more serious purpose: a trial run. Nebula Genomics already uses blockchain technology to allow 15,000 people whose entire genomes it has sequenced to grant temporary access to their data to specific users (such as pharmaceutical companies searching for links between genes and diseases). NFTs could in future provide a handy system to let customers make money from those exchanges, says Obbad.
A few other companies are similarly experimenting with ways for customers to sell genomic data on blockchain marketplaces. The idea is to give users more control of their data and to direct profits straight to the individuals, thereby encouraging more people to get their genomes sequenced.
But some note that these goals can be achieved without NFTs. The plan to auction an NFT for Church’s genome “is a PR stunt”, says Yaniv Erlich, a computer scientist at Columbia University in New York City and chief science officer of MyHeritage, a genome-sequencing and genealogy company based in Or Yehuda, Israel.
Selling personal genomes opens up ethical issues, says bioethicist Vardit Ravitsky at the University of Montreal in Canada, such as whether any individual truly owns their genome, given that much of it is shared with family members. She also notes there are already debates about whether people should be allowed to make money from their biological resources, for example through sperm donation. The problem of selling data, she says, “will be the next generation of these issues”.
There are plenty of “open questions”, agrees Obbad, who says that the proposal to sell an NFT featuring Church’s genome had been “a good conversation starter”.
