A Consensus Algorithm Based on Risk Assessment Model for Permissioned Blockchain

Table 5

Scoring basis for Byzantine fault tolerance.

Value	Range of Byzantine fault tolerance	Description
0	0%	Consensus algorithm that completes failure to recognize Byzantine behavior in the network.
0.3	1%-16%	Consensus algorithm that has ability to tolerate a small number of Byzantine nodes in the network.
0.5	17%-33%	Consensus algorithm that has ability to tolerate several numbers of Byzantine nodes in the network.
0.7	34%-51%	Consensus algorithm that has ability to tolerate no more than half of Byzantine nodes in the network.
1	>51%	Consensus algorithm that can withstand 51% of attacks.
