Bitcoin City

In 2021, the the president of El Salvador in Central America declared Bitcoin legal tender. So businesses had to accept the digital currency as well as US dollars. The country had already abandoned its own currency, the colón, in 2001.

By many accounts, the move to Bitcoin has not gone well. Vendors are reluctant to exchange Bitcoin for goods and services, not least due to the volatility of the currency and the time it takes for the Bitcoin blockchain to validate a transaction. The International Monetary Fund (IMF) has urged El Salvador to abandon the use of Bitcoin as national currency, stressing the “large risks associated with the use of Bitcoin on financial stability, financial integrity, and consumer protection.”

Even more interesting from an urban perspective is the President’s adoption of a new idea for a city, Bitcoin City. Here’s an account in the New Scientist

“His government has teamed up with a company called Astro Babies to launch a virtual casino where guests can gamble bitcoin and trade NFTs (non-fungible tokens), with a physical branch in El Salvador. In November 2021, he presented his vision for Bitcoin City, a tax-free metropolis to be built in the shape of a bitcoin logo at the base of Conchagua volcano.”

The electricity grid of the new city is to be powered by geothermal energy from the Conchagua stratovolcano. The city plan is already designed by Mexican architect Fernando Romero. The city will sit aside the volcano and follows the usual utopian circular plan form. It will be ecologically sustainable, and the Bitcoin “mining” will also be powered by electricity generated from geothermal energy.

Bitcoin “mining” of course associates nicely with volcanoes and geothermal energy, but Bitcoin is not dug up from the ground. As we know, vast electrical resources are needed to drive and cool the banks of computers that verify transactions on the globally-distributed blockchain. Organisations, cities or countries with sufficient computer power compete to solve proof-of-work calculation challenges produced by the blockchain algorithms. In this virtual casino, the winners are rewarded with bitcoin.

The Treehugger blog site provides a good explanation of the ambitions of the Bitcoin City, about which more needs to be said, especially in light of a tweet from President Nayib Bukele this week.
