Detectable, Traceable, and Manageable Blockchain Technologies BHE: An Attack Scheme against Bitcoin P2P Network

Table 1

For the same type of node, the more malicious IP prefixes, the higher the optimal attack efficiency (the shorter the required attack time). The nodes running for 30 days are the least affected by this rule.

Node type	Number of malicious IP prefixes	Optimal attack efficiency(min)
Node running for 30 days	25	<6 min
	50	<5.5 min
	75	<2.5 min
	100	<1 min
Node running for 20 days	25	<17 min
	50	<14 min
	75	<7 min
	100	<6 min
Node running for 10 days	25	<13 min
	50	<9.5 min
	75	<5.5 min
	100	<5 min
