I don't know much about Liquid, I THINK it is something like lighting for assets (this sounds good for me).
Blockstream have participated in blocksize war alongside me and people like Adam Back and Gregory Maxwell did great job at that time. As to epstein files, I have mixed feelings.
On one hand I think it might be forgery to separate us. On the other this might have allowed infiltration if its real.
I would tread carefully when interacting with them.
