How the ledger works

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

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.
