Blockchain-Based Cyber Threat Intelligence Sharing Using Proof-of-Quality Consensus

Algorithm 2

Pseudocode for proof-of-quality algorithm.

	Data:: Validators
	: Validator Rating Matrix
	: Number of selected validators
	: q-first variable
	Result: Calculate (equation (9)) and reach Consensus
(1)	initialisation\;
	/for each validator/
(2)	fordo
(3)	Outlier Detection;
(4)	Calculate ; //equation (4)
(5)	; //create ordered list equation (5)
(6)	ifthen
(7)	; //to all validators
(8)	end
(9)	end
(10)	Construct matrix ;//equation (6)
	/ each validator vote on /
(11)	fordo
(12)	fordo
(13)	Construct matrix ; //equation (7)
(14)	end
(15)	end
(16)	Construct matrix ; //equation (8)
(17)	do
(18)	calculate ; //equation (9)
(19)	if unique winner then
(20)	Consensus = TRUE
(21)	else
(22)	;
(23)	end
(24)	While Consensus = TRUE;
