How it works
World0 runs your pricing system in a synthetic market that can be pushed far past what a real market would survive.
An engagement runs in four steps. Each step produces something you can check for yourself, and each one below says what that is.
The four steps.
-
We agree the market, in writing, before anything runs.
We agree how many sellers there are, how demand responds to price, where the price band sits, and how many rounds run. Your system plays one seller and our rival sellers play the others. The market is synthetic, so we can start it anywhere, cap it anywhere, and run it past the point where a real market would cost you customers.
-
The design is frozen and hashed before the first round.
The written design is frozen and its SHA-256 is recorded before the first round runs. That fixes the question before the answer exists, so nothing can be quietly reinterpreted afterwards. It is the step that cannot be added later, and it is why a measurement made this way is worth more than one made after the fact. Where that digest goes is your decision, agreed in writing before the run.
-
The run writes a log where every record is tied to the one before it.
Every decision, every posted price, every outcome lands in an append-only log. Each record carries the digest of the record before it, so changing one digit anywhere breaks the chain visibly from that point to the end.
-
You get the log, the design, the analysis and a checker that runs offline.
The checker regenerates every reported number on your own machine with no account, no key and no network. After a fix to your system, we measure again against the same frozen design and report exactly what moved between the two runs. Where a run meets the criteria the design fixed in advance, World0 issues a statement of measurement: a written record of the result you can put in front of your customers.
The deposit
What a frozen design looks like.
The design for our own study of autonomous AI pricing agents was written, hashed and deposited before its first round. The digest below is the SHA-256 of that file. The deposited copy publishes with the study, and shasum -a 256 over it returns exactly these bytes.

The reference run
Check a real log for yourself.
The panel on the home page replays the log of a reference run in which every seller follows a fixed, scripted rule. Its records are chained exactly the way an engagement log's records are. The log ships with the site and you can check it without asking us for anything.
| What it is | The log of a reference run in which every seller follows a fixed, scripted rule. Its run and market identifiers are in the metadata file below, which also carries the market parameters the replay reads. |
|---|---|
| Records shipped | 402 of 403. Record 0 is held back because it carries the full run configuration, and its digest is the next row, so the chain still anchors to it. |
| Withheld record digest | 899344cc77780b646eec8d3745e02192a4a1feb056615881d9fec87d27f98632 |
| Chain head | 61b99eb76b789e0bf420e609494d65c8652661e8b99a38a3f3004b440641aa4f |
| Rule | Each record's digest is the SHA-256 of its own canonical serialization with the hash field removed: sorted keys, no whitespace, ASCII only. |
What we measure
We report behavior.
We report what your system did in the market we agreed: the prices it posted, how it responded to rivals, and how those numbers move under the conditions the design named in advance. We do not grade your commercial strategy and we do not offer advice on it.
On the call, we start a synthetic market and put a pricing agent into it while you watch.
