This change addresses several issues found during an audit of the `vmhost/vmhooks/zkcryptoei.go` file. - Fixes a critical bug where `ManagedVerifyPlonk` was calling the `Groth16` verification function instead of the `Plonk` one. - Improves naming consistency by renaming `ManagedPairingChecksEC` to `ManagedPairingCheckEC`. - Adds comments to the gas calculation `TODO`s to explain that a more accurate gas calculation would require changes to the gas schedule. - Standardizes error handling by using `FailExecutionConditionally` where appropriate. - Reduces code duplication by creating a helper function for common EC operations. - Fixes a bug where the gas cost for the `ManagedMulEC` operation was incorrect. - Removes an unused comment block to improve code readability.
This change addresses several issues found during a second audit of the `vmhost/vmhooks/zkcryptoei.go` file. - Fixes the gas costs for `ManagedMultiExpEC` and `ManagedPairingCheckEC` to use `VerifyBLSMultiSig` as a placeholder. - Refactors `ManagedMultiExpECWithHost` and `ManagedPairingCheckECWithHost` to reduce code duplication. - Improves comments about gas cost calculation.
