El Salvador made history on June 9, 2021, when its congress passed the Bitcoin Law with a supermajority vote, making the cryptocurrency legal tender alongside the U.S. dollar. Three days later, the implications of this groundbreaking decision were still reverberating through the global financial system, with blockchain technology at the center of an unprecedented national experiment.
TL;DR
- El Salvador became the first nation to adopt Bitcoin as legal tender on June 9, 2021
- BIS official Benoit Coeure called the move an “interesting experiment” but questioned Bitcoin as a means of payment
- IMF raised macroeconomic, financial, and legal concerns about the law
- President Bukele announced plans for volcano-powered Bitcoin mining using geothermal energy
- The government began developing the Chivo digital wallet infrastructure for nationwide BTC transactions
- Bitcoin traded at approximately $35,552, down nearly 45% from its April 2021 all-time high
BIS and IMF Respond to El Salvador’s Blockchain Gambit
The institutional backlash came swiftly. Benoit Coeure, head of the Innovation Hub at the Bank for International Settlements and a former member of the European Central Bank’s executive board, addressed the situation directly at a Bank of England event on June 11. Coeure, who chaired the BIS Committee on Payments and Market Infrastructures from 2013 to 2019, offered a measured but pointed assessment.
“El Salvador, that is an interesting experiment indeed,” Coeure remarked. But he doubled down on the BIS position, stating plainly: “We have been clear at the BIS that we don’t see bitcoin as having passed the test of being a means of payments. Bitcoin is a speculative asset and should be regulated as such.”
The International Monetary Fund weighed in with its own concerns, stating that the “adoption of bitcoin as legal tender raises a number of macroeconomic, financial and legal issues.” The IMF’s statement carried particular weight given El Salvador’s ongoing loan negotiations with the institution, which were valued at approximately $1 billion.
Volcano-Powered Mining: A Blockchain Innovation Vision
President Nayib Bukele, never one to shy away from bold announcements, revealed plans to harness El Salvador’s volcanic geothermal energy for Bitcoin mining. The proposal called for building mining facilities near active volcanoes, tapping into the country’s abundant renewable geothermal resources to power energy-intensive blockchain operations.
The concept of “volcano mining” represented a novel intersection of blockchain technology and renewable energy infrastructure. El Salvador sits along the Pacific Ring of Fire and possesses significant geothermal energy potential, with an estimated 2,100 megawatts of geothermal capacity. The initiative was pitched as 100% clean, 100% renewable, with zero emissions — addressing one of the most persistent criticisms of Bitcoin mining’s environmental footprint.
Engineers and blockchain developers began assessing the technical feasibility of connecting mining rigs directly to geothermal power plants, creating a model where energy generation and cryptocurrency mining could coexist sustainably. If successful, El Salvador could set a precedent for other volcanic nations to develop similar blockchain infrastructure.
Building the Chivo Wallet: National Blockchain Infrastructure
The Bitcoin Law mandated that all economic agents in El Salvador accept Bitcoin as payment when offered, creating an urgent need for accessible blockchain infrastructure. The government’s response was the Chivo wallet — a state-sponsored digital wallet designed to enable seamless Bitcoin transactions for every citizen.
The Chivo wallet initiative represented one of the most ambitious blockchain deployment projects ever undertaken by a sovereign government. The technical requirements were enormous: a system capable of handling transactions for a population of 6.5 million people, many of whom had never used cryptocurrency or even owned a smartphone. The wallet would need to support both on-chain Bitcoin transactions and potentially Lightning Network payments to minimize fees and confirmation times.
Each citizen was promised a $30 Bitcoin airdrop upon registering for the wallet, requiring the government to build not just the application but the entire backend infrastructure including identity verification, transaction processing, and customer support systems. The Lightning Network integration was particularly significant, as it would allow instant, near-zero-cost transactions — essential for everyday purchases like groceries and utilities.
The Technical Challenges of National Blockchain Adoption
Blockchain developers and infrastructure experts identified several critical challenges that El Salvador would need to address. Bitcoin’s base layer processes only about 7 transactions per second, far below what a national payment system requires. The Lightning Network, while promising for scaling, was still relatively young in mid-2021 and had not been tested at national scale.
Price volatility presented another technical hurdle. With Bitcoin at approximately $35,552 on June 12 — having dropped roughly 45% from its April high near $64,000 — merchants needed real-time conversion tools to price goods accurately. The Bitcoin Law addressed this by requiring automatic conversion to USD at the point of sale, but building reliable, low-latency conversion infrastructure required sophisticated API integrations with multiple exchanges.
Network reliability also remained a concern. Internet penetration in El Salvador was estimated at roughly 50-60% in 2021, meaning a significant portion of the population would need either expanded connectivity or alternative access methods to use the blockchain-based payment system.
Global Financial Regulators Tighten Crypto Rules
El Salvador’s Bitcoin Law emerged during a broader regulatory crackdown on cryptocurrencies worldwide. Financial regulators from major economies proposed additional capital requirements for banks holding crypto assets, reflecting growing institutional concern about the systemic risks of digital asset integration.
In the United States, senators increased efforts to regulate and trace cryptocurrency transactions, while China intensified its crackdown on Bitcoin mining operations, particularly in Sichuan province. These concurrent regulatory pressures created a challenging backdrop for El Salvador’s blockchain ambitions, as the country would need to navigate an increasingly complex international compliance landscape while building its domestic crypto infrastructure.
Why This Matters
El Salvador’s Bitcoin Law represents the first real-world test of blockchain technology as national financial infrastructure at scale. The technical infrastructure being built — from volcano-powered mining to the Chivo wallet — could serve as a blueprint for other developing nations exploring blockchain adoption. If successful, it proves that blockchain can function as core national payment infrastructure; if it fails, it provides equally valuable lessons about the limitations of current blockchain technology. The BIS and IMF pushback highlights the fundamental tension between decentralized blockchain networks and traditional financial institutions — a tension that will define the next decade of financial technology development.

volcano powered mining was such a wild pitch from bukele. turns out geothermal actually works for this though
geothermal mining from a volcano sounds like a sci fi plot but el salvador actually built it. the infrastructure is still running too, not just a photo op
volcano_hodlr the geothermal plant near Berlin municipality is still running. 1.5MW dedicated to mining. say what you want about bukele but he actually shipped the volcano thing
the IMF threatening to cut loans over btc adoption and el salvador just went ahead anyway. say what you want about bukele but the man commits
IMF threatening to cut a billion dollar loan over btc adoption and bukele just ignored them. regardless of what you think about the guy that took actual political courage
btc at 35k and down 45% from ATH when they adopted it. people called it reckless but that entry point aged pretty well
chivo wallet had bugs on launch day and people still downloaded it because the $30 BTC airdrop was too good to pass up. adoption through incentives actually worked
Chico M. the $30 airdrop was genius. cost them maybe $4M total and onboarded millions of wallets. cheapest user acquisition in crypto history
coeure calling it interesting while simultaneously warning about it. peak institutional hedging right there
legal tender means merchants HAVE to accept it. that was the radical part. no other country forced BTC adoption at the merchant level
volcano powered mining was the headline grabber but the Chivo wallet rollout was a disaster. servers crashed on day one and people couldnt access their $30 BTC bonus
chivo wallet bugs were bad but the remittance savings were real. salvadorans sending money home went from 10% western union fees to nearly free. thats the actual use case nobody talks about
BIS calling it an experiment was diplomatic. the IMF basically threatened to cut off lending over the bitcoin law. bukele went ahead anyway
