I too remain invested in Crypti and offer my encouragement to the devs to keep up their commitment and hard work.
I believe that Crypti can still succeed BIG TIME even if the PoT algorithm is eventually proven infeasible. What makes Crypti special is its
emphasis on commerce.
If you have say 500 vendors running a $75 Crypti node based on a cubieboard2 or a PCduino (
http://www.pcduino.com/ ),
then the Crypti network is secure. The cost of running that network becomes a trivial business expense funded by a tiny increase in vendor sales costs, not forging fees captured from running a node.
(And such a Crypti network would be a HELL of a lot cheaper than the Bitcoin miner ASIC rat-race).
If the Crypti network can be secured solely by vendors running under just PoI/PoP,
WHAT IS THE REASON FOR TRYING TO IMPLEMENT PoT? With PoT, we reward forgers for keeping the network up. Otherwise, we would either need a continuous central system for network continuity, or use a Proof of Stake system like NXT, where a few whales get all the forging earnings. The PoT value resets after a successful bloc is forged, giving every up-node a turn at forging. Any coin without active miners has a network continuity problem.
PoI, Proof of Identity, is used to assure a user that a merchant has been verified by Cryptsi, and to reward merchants for using XCR:
An application, 1000XCR, and verification by10 forgers are necessary to become a verified merchant. The 10 forgers split the 1000XCR equally. After this, the merchant will be identified by a unique address and will receive half of the transaction fees generated from his sales.
PoP, Proof of Purchase, is a simple algo to add a little weight, but not a lot of weight, to a potential forger
You also mentioned running a node off a cubieboard, or a microPC type computer. That is already something the devs are working on.
