Thinking aloud, we could do a 2:3 multisig for the mining escrow with CK, Willi, or others on the forum here..
A multisig is certainly the only way where distribution is cryptographically enforced unless CK is willing to alter the pool code so that both addresses (yours and ours) are included in the coinbase and the rewards are distributed based on work.
And for the record, I did talk to Heather (one of Rigly founders), and she does approve that Evan, aka eb66 is her partner. I can't see beyond my PC screen, but I do think these folks are genuine; the amount of work they put in doesn't suggest that they are planning a scam. Obviously, "Never trust, always verify," but I am saying this so that Willi and the rest of the forum members take eb66 seriously and engage in conversation.
As for rigly folks, obviously, the first step would be to verify that Willi's account is still operated by the same person (ask him to sign a message from one of his known/stacked addresses); if that checks out, rest assured that Willi is to be trusted given his history on the forum.
Another member I would recommend to be part of the multisig would be philipma1957.
BTW, Willi hasn't visited the thread for so long, maybe reach out to him via PM?
I'm still the same Willi and I'm still active. I'm just writing a little less in this post, since I'm no longer hosting block parties.
Two reasons that drove me to do this are a) Nicehash wanted to know too much and b) the legal situation in Germany.
I don't want to participate in it at the moment (no time). If I do, I'll organize block parties myself again. But first I need to make time for that and check the legal and tax situation.
But I wish you luck and to everyone who takes part, I'll keep my fingers crossed that it's not a scam.
Best regards,
Willi
