Wall Street is a competition, a Darwinian battle for the almighty dollar. Gordon Gekko said that greed is good, that it captures the essence of the evolutionary spirit. A hedge fund hunts for an edge and then maniacally guards it, locking down its trading data and barring its traders from joining the company next door. The big bucks lie in finding market inefficiencies no one else can, succeeding at the expense of others. But Richard Craib wants to change that. He wants to transform Wall Street from a cutthroat competition into a harmonious collaboration. <\/p>\n
This morning, the 29-year-old South African technologist and his unorthodox hedge fund, Numerai, started issuing a new digital currencykind of. Craibs idea is so weird, so unlike anything else that has preceded it, that naming it becomes an exercise in approximation. Inspired by the same tech that underpins bitcoin, his creation joins a growing wave of what people in the world of crypto-finance call digital tokens, internet-based assets that enable the crowdsourcing of everything from venture capital to computing power. Craib hopes his particular token can turn Wall Street into a place where everyones on the same team. Its a strange, complicated, and potentially powerful creation that builds on an already audacious arrangement, a new configuration of technology and money that calls into question the markets most cherished premise. Greed is still good, but its better when people are working together. <\/p>\n
Based in San Francisco, Numerai is a hedge fund in which an artificially intelligent system chooses all the trades. But its not a system Craib built alone. Instead, several thousand anonymous data scientists compete to create the best trading algorithmsand win bitcoin for their efforts. The whole concept may sound like a bad Silicon Valley joke. But Numerai has been making trades in this way for more than a year, and Craib says its making money. Its also attracted marquee backers like Howard Morgan, a founder of Renaissance Technologies, the wildly successful hedge fund that pioneered an earlier iteration of tech-powered trading. <\/p>\n
The system is elegant in its way: Numerai encrypts its trading data before sharing it with the data scientists to prevent them from mimicking the funds trades themselves. At the same time, the company carefully organizes this encrypted data in a way that allows the data scientists to build models that are potentially able to make better trades. The crowdsourced approach seems to be workingto a point. But in Craibs eyes, the system still suffers from a major drawback: If the best scientist wins, that scientist has little incentive to get other talented colleagues involved. The wisdom of the crowd runs up against Wall Streets core ethos of self-interest: make the most money for yourself. <\/p>\n
Thats where Craibs new token comes in. Craib and company believe Numerai can become even more successful if it can align the incentives of everyone involved. They hope its new kind of currency, Numeraire, will turn its online competition into a collaborationand turn Wall Street on its head in the process. <\/p>\n
In its first incarnation, Numerai was flawed in a notable way. The company doled out bitcoin based on models that performed successfully on the encrypted test data before the fund ever tested them on the live market. That setup encouraged the scientists to game the system, to look out for themselves rather that the fund as a whole. It judged based on what happened in the past, not on what will happen in the future, says Fred Ehrsam, co-founder of marquee bitcoin company Coinbase and a Wall Street veteran. <\/p>\n
But Craib feels the system was flawed in another waythe same way all of Wall Street is flawed. The data scientists were still in competition. They were fighting each other rather than fighting for the same goal. It was in their best interest to keep the winnings to themselves. If they spread the word, the added competition could cut into their winnings. Though the scientists were helping to build one master AI, they were still at odds. The fund and its creators were at cross-purposes. <\/p>\n
Why is tech positive-sum and finance zero-sum? Richard Craib <\/p>\n
Today, to fix that problem, Numerai has distributed Numeraire1,000,000 tokens in allto 12,000 participating scientists. The higher the scientists sit on the leaderboard, the more Numeraire they receive. But its not really a currency they can use to pay for stuff. Its a way of betting that their machine learning models will do well on the live market. If their trades succeed, they get their Numeraire back as well as a payment in bitcoina kind of dividend. If their trades go bust, the company destroys their Numeraire, and they dont get paid. <\/p>\n
The new system encourages the data scientists to build models that work on live trades, not just test data. The value of Numeraire also grows in proportion to the overall success of the hedge fund, because Numerai will pay out more bitcoin to data scientists betting Numeraire as the fund grows. If Numerai were to pay out $1 million per month to people who staked Numeraire, then the value of Numeraire will be very high, because staking Numeraire will be the only way to earn that $1 million, Craib says. <\/p>\n
Its a tricky but ingenious logic: Everyone betting Numeraire has an incentive to get everyone else to build the best models possible, because the more the fund grows, the bigger the dividends for all. Everyone involved has the incentive to recruit yet more talenta structure that rewards collaboration. <\/p>\n
Whats more, though Numeraire has no stated value in itself, it will surely trade on secondary markets. The most likely buyers will be successful data scientists seeking to increase their caches so they can place bigger bets in search of more bitcoin rewards. But even those who dont bet will see the value of their Numeraire grow if the fund succeeds and secondary demand increases. As it trades, Numeraire becomes something kind of like a stock and kind of like its own currency. <\/p>\n
For Craib, a trained mathematician with an enormous wave of curly hair topping his 6-foot-4-inch frame, the hope is that Numeraire will encourage Wall Street to operate more like an open source software project. In software, when everyone shares with everyone else, all benefit from the collaboration: The software gets better. Google open sourced its artificial intelligence engine, for instance, because improvements made by others outside the company will make the system more valuable for Google, too. <\/p>\n
Why is tech positive-sum and finance zero-sum? Craib asks. The tech companies benefit from network effects where people behave differently because they are trying to build a network, rather than trying to compete. <\/p>\n
Craib and company built their new token atop Ethereum, a vast online ledgera blockchainwhere anyone can build a bitcoin-like token driven by a self-operating software program, or smart contract. If it catches on the way bitcoin has, everyone involved has the incentive to (loudly) promote this new project and (manically) push it forward in new ways. <\/p>\n
But getting things right isnt easy. The risk is that the crypto-economic model is wrong, says Ersham, Tokens let you set up incentive structures and program them directly. But just like monetary policy at, say, the Federal Reserve, its not always easy to get those incentive structures right. <\/p>\n
In other words, Craibs game theory might not work. People and economies may not behave like he assumes they will. Also, blockchains arent hack-proof. A bug brought down the DAO, a huge effort to crowdsource venture capital on a blockchain. Hackers found a hole in the system and made off with $50 million. <\/p>\n
Craib may also be overthinking the situation, looking for complex technological solutions to solve a problem that doesnt require anything as elaborate as Numeraire. Their model seems overly complicated. Its not clear why they need it, says Michael Wellman, a University of Michigan professor who specializes in game theory and new financial services. Its not like digital currency has magical properties. Numerai could try a much more time-honored approach to recruiting the most talented data scientists, Wellman says: pay them. <\/p>\n
After today, Craib and the rest of Wall Street will start to see whether something like Numeraire can truly imbue the most ruthless of markets with a cooperative spirit. Those thousands of data scientists didnt know Numeraire was coming, but if the network effects play out like Craib hopes they will, many of those scientists have just gotten very, very rich. Still, that isnt his main purpose. Craibs goals are bigger than just building a hedge fund with crowdsourced AI. He wants to change the very nature of Wall Streetand maybe capitalism. Competition has made a lot of people wealthy. Maybe collaboration could enrich many more. <\/p>\n
