A Novel Semifragile Consensus Algorithm Based on Credit Space for Consortium Blockchain

Algorithm 1

Node layering and credit space allocation algorithm.

Input: Cn (node’s credit value array)
Output: spaceArray (node’s credit space array)
(1)	spaceArray[] = {0}; //Initialization of Credit Space Array
(2)	for i = 1 to n do //Traversing all nodes
(3)	if JudgePrsion (Cn[i]) //Judge if the node is in the prison layer, if it is, do not allocate
(4)	space
(5)	continue;
(6)	end if
(7)	if i =  = 0 //When i is the first node in space
(8)	spaceArray[i]=(Cn[i]/countSum (Cn)) ∗ spaceLength; //Calculating the length of credit
(9)	space
(10)	continue;
(11)	end if
(12)	spaceArray[i] = (Cn[i]/countSum (Cn)) ∗ spaceLength + spaceArray[i − 1]; //The length of
(13)	credit space after becoming an accounting node, Cn is an array of normal layers
(14)	end for
