Made the Autonomy and Janus puzzles for decred.org and the XIXOIO puzzle for xixoio.com. Both sites are gone and the catalog keeps the carriers.

Who this is

Zden Hlinka is a coder who draws. His site introduces him as codært, visual engineering, digital alchemy, Satori / SK, experimental coder, live visuals performer, digital painter, demoscener. Satori is the Slovak demogroup. The puzzles started in June 2016 with Level 1, a picture with a private key in it, and haven't really stopped: sixteen so far on Bitcoin, Ethereum, Litecoin and Decred, plus a Monero one the dataset can't verify, up to Level HALV for the fourth halving in 2024. Two of the Bitcoin ones are still open.

He's the author who commissions best. Decred paid for Autonomy and Janus. XIXOIO paid for an Ethereum one. Nethemba sponsored the DefCon 24 puzzle. The sponsor sites are gone and crypto.haluska.sk keeps the carriers, which is why it's the profile that matters.

What the record says

His own site for the self description. His Steemit write up of the Codex puzzle for the full name, because he signed it there. The catalog page twice: once for the range of the series and the support address, once for the commissions whose original sites are offline. He publishes under his name and his handle both, so both are on the record.
