When a day ends, ChartRunner takes the final results, turns every entry into a fingerprint, and combines all fingerprints into one short code (a Merkle root). That code is written to the Solana blockchain in a public memo, with the number of entries.
After that, nobody (including us) can change a past result without the code changing, and the old code stays on the chain forever. You can check your own entry below: your browser recomputes the code from your entry and a short proof, then compares it with what the chain says. Nothing on this page asks you to trust our server's word.
What it does not prove: that a score was earned fairly (the server replays every run for that), or that nobody was left out. The entry count is on-chain, so a missing entry is something you can check for yourself.
