A million-dollar Bitcoin scavenger hunt began only two weeks ago, but one player has already built software to help others co-ordinate their detective efforts.
Satoshi’s Treasure works like this: game organizers split keys to $1 million worth of BTC into 1,000 “shards.” A newsletter sends hints for their discovery, and the first to collect 400 shards immediately unlocks the full prize.
When the game started, player John Cantrell hacked his way to the first three keys within minutes. He later detailed his methods with a walkthrough posted to GitHub.
To date, Satoshi’s Treasure has released five clues. At pixel time, the latest remains unsolved, but Cantrell did manage to unlock the fourth key with relative ease.
Satoshi’s Treasure mini-games will feature instant prizes
According to Primitive Ventures (one of the firms behind the quest), the overall goal is to educate those who know nothing about Bitcoin BTC or cryptocurrency, and encourage them to participate.
“We absolutely guarantee that if you know a ton about literally any subject, there will be some clue that requires your knowledge,” said Primitive Ventures. “Most of the clues have nothing to do with cryptocurrency. The puzzles are designed by puzzle experts and enthusiasts around the world […].”
The game’s designers are yet to set a timeline for the game, but incoming clues are promised to be extremely diverse, and will now be arriving at random.
Founding partner Dovey Wan also confirmed there will be smaller Satoshi’s Treasure side-quests. Some will impact the primary game, while others will be independent and come with their own prizes.
“These might be geographically localized, or require a very specific set of knowledge,” Wan told Hard Fork. “In the lead up to the main hunt we did ‘mini hunts’ like this to test some game dynamics at college campuses in the US, for example, and those were fun—we’ll do more things like that soon.”
She also explained the $1 million valuation of the prize could fluctuate. While the amount of Bitcoin stashed away is certainly set, disclosing the exact amount would reveal the wallet, which is itself part of a clue soon to be released.
“For now, just know that it’s around $1 million of value (fluctuating a bit as BTC tends to do),” said Wan. “If it goes up a lot, we won’t remove any BTC—the prize will just be bigger. Conversely, if it crashes, so be it.”
Hacker tip: concentrate on what the clue is REALLY saying
Unlike the first set of clues (which relied on QR-codes and encrypted passwords), this one involved following a link buried within a GIF.
Users were then directed to purchase a ‘digital egg’ from a web store for a little over a dollar, which held instructions for claiming the key.
While this kind of clue-hacking comes second nature to Cantrell, it’s understandable when you consider he’s operating with over 20 years of practical software development know-how, and even holds advanced degrees in computer science.
Still, those keen to participate in the Bitcoin hunt without similar work experience shouldn’t be deterred. “When a new clue drops I try to figure out what the clue is really saying, what exactly does the puzzle creator want me to pick up on,” Cantrell told Hard Fork.
“For example, with this most recent clue, the link to the GIF said ‘nothing is what it seems.’ I’ve seen clues like this in other puzzles and it immediately makes me think that the file is not the type it appears to be at first glance,” he continued. “In this case, we were given a GIF file but it ended having a ZIP file hidden inside of it that contained the next clue.”
Cantrell explained he’s spent a lot of time playing other alternate reality games like Not Pron and Cicada 3301. He noted that puzzle creators often re-use ideas as there’s a limit to the number of techniques and tools that can obfuscate information.
“So, if you’ve played through and understand the solutions to similar puzzles, then a lot of those same techniques will be obvious the next time you see them (or something similar) again,” said Cantrell.
Co-ordinating teams is going to be a real challenge
The thing is, players replicating Cantrell’s success might soon be out of luck. The longer the hunt goes on, the more disincentive there is to share keys – so you should probably learn what you can, while you can.
“I do not intend to continue fully open sourcing all of my methods going forward,” Cantrell told Hard Fork. “In the beginning of the hunt, I think most of the keys will become public knowledge and I enjoy sharing my thoughts on each puzzle, so I don’t see the harm in it.”
“I’m part of a team but I still enjoy trying to solve everything I can by myself,” Cantrell continued. “However, there are definitely some things that aren’t be possible without a team (e.g. being in certain physical locations).”
There’s also the problem of what happens when someone collects the first 400 key shards and unlocks the $1 million prize, especially considering playing solo seems borderline impossible.
Cantrell expressed there’s no simple solution. He mentioned one idea would be to have some subset of leaders in a group meet to combine the key shards and split the profits, in person.
Another involved using cryptography to ensure fair distribution, but he wasn’t exactly sure if it was actually possible.
“Teams need to come up with a way to manage these key shards in the most trust-minimized way possible,” Cantrell continued. “Teams could give all key shares they find to a trusted leader, but as soon as they have 400 shares, the leader could just steal the money for himself.”
To help, Cantrell actually designed and built software just for Satoshi’s Treasure. Ordobot is a Discord plugin that helps teams organize, make decisions, track contributions, and solve puzzles quickly. It even has functionality to run cryptographic tools directly in-app.
