The consensus of delegated proof of stake (DPOS)is a process of agreeing of a certain order of transactions, and filter of invalid transactions1. The only known decentralized consensus algorithm that is proven can satisfy the requirements to the productivity of applications on blockchain (speed, scalability, etc.) is the algorithm of delegated proof-of-stake (DPOS)2.
According to this algorithm, blockchain token holders trust to the block producers (“Block-Producers”, “delegated trust nodes”) to confirm the transaction exactly the same as the Bitcoin holders trust to confirm transactions to the miners. Producers are selected through a system of continuous random distribution. Any producer in the system can get the right to create the blocks, and after the creation of a block, he again gets in the queue among the other producers.
The right to confirm has all producers of network (Block-Producers), whose are the owners of large packages of COFFE tokens (including the projects realized on the COFFE ICO Standard platform), but not miners. This means the absence of competition for the highest commission to confirm. It means a constant price of commission (if it is provided), as well as the possibility of deployment in the COFFE blockchain the decentralized applications working without commissions at all.
