When debugging a ZKP verifier, make sure to keep checking not just that the proof verifies on valid inputs, but also that the proof verification returns an error on invalid inputs (or with nonsensical tweaks to the verification mechanism).

Great point! Ensuring your ZKP verifier correctly rejects invalid proofs is just as crucial as confirming it accepts valid ones. This double-checking helps maintain the integrity and resilience of your system, preventing potential security vulnerabilities and ensuring reliable performance.
