Since there was a question before about PoET I found this part in the whitepaper
"Proof-of-elapsed time (PoET) - (Reference #4) is a relatively new concept. Coins are distributed based on the proof that the user was doing some specific action for a rather long period of real time. Proof of time algorithm was invented by Intel and it is mainly associated with their hardware platform that provides very fast consensus model. It generates random numbers (wait time) on miners nodes and then chooses the node with the lowest number. So, it works like a lottery but with more complex algorithm designed to provide more optimizations. Intel promises that this algorithm cannot be broken by external actions and provides honest consensus model. This makes
PoET perfect for private Blockchain when you need performant distributed storage and dont want to force your hardware to make complex computations. The only minus is the restriction on Intels platform (Sawtooth Lake). The proof-of-elapsed time has not become popular and well adopted yet. But in the near future it may be intensively developed. Future adoptions may not be the exact algorithm designed by Intel, but rather some variations of the concept."
Thanks for sharing that,i wasnt sure exactly about this proof of elapsed time and how it works.
