Handshake was co-founded by the guy claiming to be a Korean prince who attacked (and killed) freenode and was very abusive to the open source projects formerly there. I wouldn't touch it. He is extremely litigative. ref: http://www.hashedpost.com/2018/11/hashed-people-handshake-co...
The first part of his attack on Freenode was his attempt to push his Handshake cryptocurrency on the users there. It escalated quickly after this failed. ref: https://www.coindesk.com/markets/2018/08/02/handshake-reveal...
