Assange himself explains it very well. He gave the block number and hash associated and all that matched up correctly. For tech nerds, that was very convincing.
He also gave final scores for recent sporting events. That wasn't convincing at all to me. :) For that to be convincing, I would have to take the time to research those facts and it's not in my immediate wheelhouse to do that.
It's nice he did both.
Omg the twitch chat.
and people complain here about trolls
I have to trust the super-nerd David Seamen, he did a fine job explaining it, and if I were brighter I would recite it back to you. My nerd powers go in a different direction. I'm just happy he's alive, and hope he starts appearing at the window again.
