A New Lattice-Based Blind Ring Signature for Completely Anonymous Blockchain Transaction Systems

Algorithm 4

Verification algorithm.

	Input: system public parameters PP, original message m, public keys of the ring R, blind ring signature .
	Output: 1 or 0.
	Step 1: verify that for all .
	Step 2: verify that .
	Step 3: output 1 if the verification in steps 1 and 2 passed and 0 otherwise.
