Hello,
The last months i have been thinking about a consensus algorithm
based on a "Proof Of Spend".
The features of this algorithm are significantly different than what you have seen before in cryptoland.
I shared my thoughts at the link below :
https://github.com/222247/saphari-algorithm/blob/master/main_paper.mdThe beginning (just the first lines to be honest) of this paper talks about Bitcoin algo. Maybe it will inspire other people.
It's really a technical description of a distributed consensus algo.
Merry Christmas,
