Given the present circumstance, I believe time has come for such a mechanism to succeed. Steem has proven unequal to the task of providing censorship resistance, due to it's inequity of staking. Other mechanisms for distributing stake, or equity, or decentralizing power, will now be able to attract the market for such a mechanism since Steem is no longer a potentially successful way to do it.

Namecoin and BipCoin were the projects I followed. I don't recall the specifics of the former, but the latter was based on Monero instead of Bitcoin for greater privacy.

Maybe Skynet (despite it's unportentious name) will work. There's a lot of projects in the crypto space today. Sooner or later one that will actually work will eventuate, even if by accident.

Even a broken clock is right twice a day. Monkeys, typewriters, and Shakespeare, and all that.
