Blockchain Network Propagation Mechanism Based on P4P Architecture

Algorithm 1

Blockchain_P4P propagation mechanism.

Input: Num, BlockNodeSet, DistanceSet, IP, BandWidth, AsId
Output:
(1)	NodeSet =
(2)	//Add node information to iTracker
(3)	for each do
(4)
(5)
(6)
(7)	end for
(8)	//iTracker calculates node distances
(9)	shortestPathSet = compute (BlockNodeSet, DistanceSet)
(10)	= choose (BlockNodeSet, shortestPathSet)
