Bitcoin goes live

Bitcoin goes live

“On 3 January 2009 the unknown 'Satoshi Nakamoto' started Bitcoin, money kept on a shared public ledger instead of by a bank; by 2017 it had gone from pizza money and Silk Road to Wall Street futures.”

Bitcoin is the first digital money that works without a bank, a company or a government in the middle. On 31 October 2008, six weeks after the fall of Lehman Brothers, an unknown programmer who called himself Satoshi Nakamoto posted a nine-page paper to a cryptography mailing list: 'Bitcoin: A Peer-to-Peer Electronic Cash System'. On 3 January 2009 he created the system's first block of records, and inside it he wrote the front-page headline of that day's Times of London: 'Chancellor on brink of second bailout for banks'. He released the software on 8 January, and on 12 January he sent ten bitcoins to Hal Finney, an American cryptographer, in the first transaction between two people.

The idea solved an old problem of digital cash: how to stop someone from spending the same coin twice without a bank keeping the books. In Bitcoin every computer in the network keeps a copy of one shared ledger. Payments are collected into blocks, and each block is sealed to the one before it with a cryptographic fingerprint, forming a chain, the 'blockchain'. To add a block, computers called miners race to solve a puzzle that takes a great deal of computing work; the winner is paid in new bitcoins. The reward halves about every four years, so no more than 21 million bitcoins can ever exist. The Bank of England called this shared 'distributed ledger' a genuine technological innovation in 2014.

At first bitcoins were worth almost nothing. In May 2010 Laszlo Hanyecz, a forum user in Jacksonville, Florida, paid 10,000 of them for two pizzas, the first well-known purchase of real goods. Nakamoto wrote his last forum post in December 2010 and his last known emails in April 2011, saying he had 'moved on to other things' and leaving the project to other developers led by Gavin Andresen. Who he was is still unknown; one analysis credits him with about a million early coins that have never been spent. The price swung wildly: about $30 in June 2011, under $3 by the end of that year, more than $1,100 in December 2013.

Bitcoin's anonymity also served crime. Silk Road, a hidden website opened in January 2011, used it to sell illegal drugs to more than 100,000 buyers until the FBI arrested its founder, Ross Ulbricht, in San Francisco in October 2013; he was sentenced to life in prison in 2015 and pardoned by President Trump in January 2025. In February 2014 Mt. Gox, a Tokyo exchange and one of the largest in the world, collapsed after reporting about 850,000 bitcoins missing. Governments began to fit the new money into old rules: the United States treated exchanges as money transmitters from 2013 and bitcoin as a commodity from 2015. Mining also uses a great deal of electricity: an estimated 0.14 percent of the world's supply in late 2017, and today, by the University of Cambridge's estimate, roughly 160 terawatt-hours a year.

By the end of 2017 bitcoin had reached Wall Street. Its price rose from about $1,000 at the start of the year to nearly $20,000 in mid-December, and on 18 December CME Group's Chicago Mercantile Exchange began trading bitcoin futures under the eye of the US regulator. The boom was followed by crashes and new highs, by many imitations, and in January 2024 by funds traded on American stock exchanges, approved by a regulator whose chairman still called bitcoin 'primarily a speculative, volatile asset'. To its supporters bitcoin is digital gold that no state controls; to many central banks and critics it is a costly bet with little use as money. Either way, it showed that strangers could keep a trusted shared record with no one in charge, an idea that spread far beyond money.
