Who this is

The GitHub account behind open-crypto-puzzles, and on X, @0xFlorent_. The repository README says who it is and lists the X account as the contact, so the two are one profile by the author's own word, not by guesswork.

The repository is the interesting part. It's a catalogue of public bounties, each in its own folder, each with an oracle that says yes or no to a candidate, and the logged negatives next to it. The README is honest about the hit rate: about 40 worked, a few solved. One of those few is in this dataset, Dug's student treasure hunt, address 1, taken on August 2, 2026.

The other hobby

On X the same account does contract archaeology. In May 2026 it posted about unlocking 1,003.62 ETH stuck in a 2016 ICO contract, for the original 48 investors to claim. In June it solved a TeikhosBounty contract from 2018 that had been sitting on chain for eight years with 0.5 ETH in it: submit the right 64 byte public key and the contract pays whoever did. The record keeps those as the account's own claims. They're here because they say what kind of solver this is. Riddles are half of it. The other half is reading the chain until something doesn't add up.

And the catalogue keeps paying off for other people too. The Bitcoin Movie Enigma was claimed in its issue tracker.
