How else do you get A16z to invest?

You play League of Legends while on a pitch call with them

That sounds like a real power-move from a top-tier mind.

I believe that was Sequoia? Who just massively downsized that very fund this week. (Tho he did seem to play LoL on a lot of calls…)

Presumably so that the underlying system can be auditable by 'anyone'?

That can still be done by streaming the updates to whoever wants them (can even hash each chunk of updates, and include the hash of the prior chunk in each chunk, to get a linked list of chunks, which would prevent undetected manipulation of prior chunks).
