One I didn't see the other's mention is that in Line Goes Up, Dan calls secure-scuttlebutt (SSB), a p2p messaging protocol, a blockchain.

IIRC Dan was relying on a sentence from an outdated, archived documentation site made by an open source contributor many years ago. The core SSB devs then had to try to convince people that Dan was wrong about their project. Dan refused to admit he was wrong, despite a lack of blockchain in the open source code, and just pasted a screenshot of the old docs.
