Bitcoin banks, but with drugs

- Elaine Ou

Last Tuesday, the darknet market known as AlphaBay vanished without a trace. With more than 100,000 users and an estimated US$ 800,000 in daily transactio­ns, it was the largest market in the undergroun­d web. AlphaBay administra­tors i nitially appeared on Reddit to assure users that the site was undergoing routine maintenanc­e, but with each passing day, the story seemed l ess and l ess plausible. Now that more than a week has elapsed, it looks like AlphaBay may have pulled the ultimate exit scam.

Darknet markets are hidden websites accessible through browsers such as Tor, which route encrypted communicat­ions through multiple machines to mask the user’s location. Each site hosts a unique selection of vendors peddling illicit goods such as drugs, weapons and stolen data. Darknet participan­ts are not exactly beacons of trust, so sites like AlphaBay offer an escrow service to hold bitcoin payments until a buyer confirms receipt of a delivery. Market operators typically charge a five- to 10- per- cent fee per transactio­n.

The escrow service creates a separate risk to the vendors: The l arger t he marketplac­e, the greater the amount of bitcoin in custody at any given time. A sizable market might be holding several million dollars’ worth of bitcoin in escrow, and vendors have to trust the site administra­tors not to shut it all down and run off with the deposits — a move known as an exit scam. Two years ago, a market called Evolution exited with an estimated US$ 12 million worth of bitcoin.

It ’s not a question of whether exit scams will occur; rather, it’s a question of when. The anonymous nature of these sites means that participan­ts have no recourse in the event of wrongdoing. Market operators have to calculate the optimal time for retirement, balancing their profits against the risk of a hack or police raid. Undergroun­d markets tend to have a short lifespan.

Exit scams are as old as the warehousin­g profession. In the 1640s, the outbreak of the English Civil War drew merchants’ apprentice­s to join the army, leaving merchants with no one to safeguard their surplus cash. The merchants turned to private goldsmiths, who were accustomed to safekeepin­g precious metals. Initially, there were reports of the goldsmiths packing up and skipping town, but the enterprisi­ng goldsmiths eventually discovered that profits could be maximized not by going on the lam, but by sticking around and issuing warehouse receipts in ex- cess of the gold on hand. And thus fractional reserve banking was born.

The remarkable t hing about AlphaBay is not its recent disappeara­nce, but the fact that it apparently managed to grow so large without succumbing to insider theft. This can be attributed, in part, to its unique business model. Earlier this year, a site administra­tor explained that AlphaBay was not actually in the business of e-commerce:

“You can see Alphabay like a bank: while we allow people to deposit and withdraw at will, drugs are merely a product to attract customer. The cold wallet coins aren’t just standing there: we invest in various things anonymousl­y, make money with t hose i nvestments, while always ensuring to run at 100% reserve.”

So AlphaBay is really a deposit bank! Whereas my credit union attracts customers with offers of 0.01- percent interest and a free pen, AlphaBay offers access to illegal drugs. It’s unclear how they manage to simultaneo­usly invest customer demand deposits while maintainin­g a full reserve — the numerous complaints of suspended withdrawal­s suggest that they don’t.

Bitcoin enthusiast­s tend to take a dim view of fract i onal r eser ve banking. Past situations involving an overissue of bitcoin- based debt instrument­s resulted in massive i mplosions, most notably the collapse of bitcoin- exchange giant Mt. Gox. We may never learn the true fate of AlphaBay; the undergroun­d web is littered with black markets that disappeare­d with no further explanatio­n. But it’s surely a testament to Bitcoin’s price stability that darknet markets have transition­ed to the business of banking.
