Could someone agree me, so i can make sure i understood dPOW.
It is like a normal POW-System, like BTC, but additionally it goes through the 64 notary-nodes and has to be accepted from each of them?
And another noobish question: Does it somehow decrease the speed of the blockchain?
The initial consensus method can be anything and the delayed Proof of Work consensus can be build on top of it. Thus at its core the dPoW blockchain could be either a Proof of Stake (PoS) or Proof of Work (PoW).
Since it's a bolt-on consensus mechanism, it does not affect the speed at which the main-chain processes blocks.
