The weekend of April 13-14, 2019, proved to be one of the most eventful in recent crypto history. While Bitcoin consolidated above $5,000, two remarkable stories unfolded that highlighted the growing intersection of cryptocurrency with mainstream institutions and global culture: the launch of the $1 million “Satoshi’s Treasure” hunt and the International Monetary Fund’s creation of a blockchain-based “Learning Coin” in partnership with the World Bank.
TL;DR
- A cryptic message broadcast via Blockstream Satellite on April 13-14 kicked off “Satoshi’s Treasure” — a global scavenger hunt with $1 million in Bitcoin as the prize
- The IMF and World Bank launched a private educational blockchain token called “Learning Coin” to study distributed ledger technology
- Players must collect 400 of 1,000 hidden keys using Shamir’s Secret Sharing to claim the prize wallet
- IMF Managing Director Christine Lagarde previously advocated for exploring central bank digital currencies
- Both developments underscored growing institutional and mainstream engagement with blockchain technology
Satoshi’s Treasure: A Million-Dollar Global Hunt
On April 13, 2019, a cryptic, rambling message was broadcast via the Blockstream Satellite network — a system that allows users to send data through orbiting satellites to Bitcoin nodes worldwide. The message challenged the global crypto community to embark on an unprecedented treasure hunt. Named “Satoshi’s Treasure,” the game promised a staggering $1 million in Bitcoin to whoever could piece together the puzzle first.
The hunt was designed around a cryptographic structure that would be familiar to any serious Bitcoin enthusiast. A total of 1,000 keys were to be hidden across locations around the world — both in densely populated areas and remote locations. To claim the prize, a player or team needed to collect at least 400 of these keys and use Shamir’s Secret Sharing Scheme to reconstruct the private key to a Bitcoin wallet containing the $1 million reward.
The first clue directed participants to monitor signals from four specific satellites — GALAXY18, EUTELSAT 113, TELSTAR 11N, and TELSTAR18V — at 1 PM EST on April 14. Decoding the satellite transmissions revealed GPS coordinates for ten locations around the world, where the first three keys were distributed on April 16.
Community Response and Global Excitement
The response was overwhelming. According to co-creator Eric Meltzer, people showed up en masse at the indicated locations, with some driving over three hours to reach the spots. In New York’s Times Square, a man wearing a sandwich board with a QR code concealed one of the first key fragments.
Perhaps most impressively, some participants managed to bypass the physical hunt entirely by brute-forcing the encryption used to protect the clues — a feat the organizers expected would take weeks but was accomplished in just 30 minutes. Teams quickly formed across Telegram groups and Reddit, with players speculating on the value of individual keys and strategizing about where future clues might appear.
The game validated a compelling thesis: that Bitcoin and cryptographic tools could enable an entirely new type of hybrid online-offline gaming experience, blending physical exploration with digital puzzle-solving in ways never before possible.
IMF and World Bank Enter the Blockchain Arena
While the crypto community was chasing satellite signals and QR codes, the world of institutional finance was making its own blockchain moves. The International Monetary Fund and the World Bank jointly announced the creation of “Learning Coin” — a cryptocurrency token developed specifically for educational purposes.
The token, which carries no real-world monetary value, was designed to help staff at both institutions gain hands-on experience with blockchain technology. The initiative reflected a growing recognition among the world’s most powerful financial organizations that distributed ledger technology could not be ignored.
IMF Managing Director Christine Lagarde had been laying the groundwork for this exploration. In a notable speech at the Singapore Fintech Festival in November 2018, Lagarde — the first woman to lead the IMF and a former prominent French politician — called for central banks to seriously explore the idea of central bank digital currencies. She cited the rise of digital payments and acknowledged that major cryptocurrencies including Bitcoin, Ethereum, and XRP were “vying for a spot in the cashless world.”
The Bigger Picture: Institutions Can’t Ignore Crypto Anymore
These two developments, occurring simultaneously in April 2019, painted a telling picture of where the cryptocurrency industry was heading. On one hand, the Satoshi’s Treasure hunt demonstrated the passion, creativity, and technical sophistication of the grassroots crypto community. On the other, the IMF-World Bank Learning Coin showed that the highest levels of global finance were beginning to take blockchain technology seriously as a tool for the future of money.
Notably, the Learning Coin initiative followed JP Morgan Chase’s launch of its own cryptocurrency, JPM Coin, earlier in 2019. The pattern was clear: major financial institutions were no longer dismissing crypto as a fad — they were actively experimenting with the underlying technology to understand how it might reshape the global financial system.
Developers of the Learning Coin were also reportedly exploring ways to redeem the token for some form of internal rewards, suggesting the experiment could evolve beyond mere education into a functional internal incentive system.
Why This Matters
The convergence of Satoshi’s Treasure and the IMF Learning Coin in mid-April 2019 was emblematic of a broader shift. The crypto winter of 2018 had not killed the industry — if anything, it had purified it, weeding out the speculators and leaving behind a community of builders, researchers, and enthusiasts who were genuinely excited about the technology’s potential. Meanwhile, institutions that once dismissed Bitcoin were now building their own blockchain experiments. The stage was being set for the next phase of cryptocurrency’s evolution, where grassroots innovation and institutional adoption would increasingly coexist and cross-pollinate.

catching that satellite broadcast was wild. pure cypherpunk energy. 400 out of 1000 keys using Shamir Secret Sharing, brilliant design
IMF launching a Learning Coin while Lagarde was openly discussing CBDCs. the establishment was taking notes even back in 2019
my team spent 3 weeks on the hunt. found 2 keys in Tokyo. ultimately some group from SF won but the experience was worth more than the BTC
