Proof of Mining in Blockchain Systems
share
We propose a proof of mining system. Roughly speaking, in this system the mining stake mstak(A) with discrimination index a∈[0,1] of an account A is defined by the formula: mstak(A)=(1-a)·1/ NOM+a· NOBM(A)/L, where L is the length of the block-chain, NOM is the number of miners in the block-chain, and NOBM(A) is the number of blocks mined by A.
