Cryptographic ledger technology has been around since forever (the 70s to be precise): just look at Git, SUNDR, etc.

I believe he's specifically calling out firms working on cryptocurrencies; cryptocurrencies are just one application of cryptographic distributed ledgers.

Sure, but the companies he specifically named are working on similar projects that's all.

Edit: In fact I don't know of a single company using Haskell in the crypto space I'd define as a 'scam'
