Freenode Bitcoin IRC log archive
A single compressed archive of early IRC logs from the Freenode channels #bitcoin-dev, #bitcoin-core-dev and #bitcoin-otc, one plain text file per channel with a tab-separated timestamp, nickname and message on each line. Bryan Bishop publishes it together with an OpenTimestamps proof of the archive. It covers the years before the daily gnusha.org logs begin; only messages are kept, so joins, parts and other channel events are missing.
