+### How much it cost to verify proofs using Aligned's Proof Verification Layer?
 
 The cost ($C$) of proof verification using Aligned's Proof Verification Layer is the cost of task creation ($C_{task}$) plus the cost of verifying an aggregated BLS signature ($C_{verification}$), divided by the number of proofs ($N$) in the batch, plus the the cost of reading the results on-chain ($C_{read}$).
