1 prediction · 1 assertion · 1 insight · 1 disclosure · every statement was checked. The prediction and assertion are the 2 claims: statements the public record can support or contradict. 1 is resolved, and 1 names no date, number or outcome precise enough to check. Everything else (opinions, insights, what ifs, disclosures) can never be settled by the record, so it carries no assessment.

Their most notable supported claim

Assertion Supported

Prediction Not checkable as stated

Green: Autonomous software agents transacting funds will make a huge impact

“I think companies is a terrible way to explain this, but I think software agents that have these capabilities, including the ability to essentially transact funds, ah, would make a huge difference.”

Disclosure

Green: Bitcoin core developers rejected early, inefficient versions of Zerocoin

“So we actually, when we initially came out with zero coin, it was not very efficient. We approached Bitcoin and said, Hey, this is great. You guys should adopt it. And they kind of looked at it as funny and they said, you know, this is not efficient.”
