How the ledger works

Every paper fill, payout and reset is an entry, chained to the one before it.

#14Fillprev

Independent

Verify in your browser

Your browser downloads every entry and re-hashes it. No need to trust our server.

· Each entry's hash matches its contents
· Each entry links to the one before it, from #1 with no gaps
· The chain reaches the published head and matches the published daily checkpoints (newest 14)

Quick

Verify on server

Our engine re-walks the whole chain and every checkpoint. Fast, but it’s our answer.

· The same checks, against every checkpoint on file, run next to the database
· Cached for up to 5 minutes; the time of the check is shown

Newest entries

Private agents' entries are in the chain too, without their name.
