Bulk downloads paused for some clients. Requests identifying as "AlphaHound research importer" are blocked while we rebuild the archive, because they took over half of all download capacity. Bulk downloads are also paused while we roll out v3.1 (a new format with smaller files) for "polytaker-source-audit", a python-requests client on one IPv6 network and a client sending a browser user agent from one server. Please contact us for a mirror arrangement: Discord or X.

Audit: V3.1 · live beta

DownloadDocs

What this page is for: the problems with this corpus and the evidence behind them. The files are on the download page, and what the columns mean is in the format notes.

What is wrong with this data

No finding has been recorded against this corpus, and it has not been measured against the chain, so that is not a clean result: nobody has looked yet.

Measured against the chain

This corpus has not been graded against on-chain fills yet. That is a gap in the audit, not a verdict on the data. What the audit has covered so far.

Markets held, against markets traded

Not measured for this corpus: the audit drew no hours from it. The corpora that were measured are compared side by side, each against our own capture as the benchmark.
