## What Is the Verifier’s Role in a Zero-Knowledge Proof Protocol?

The verifier is the party who receives the cryptographic proof and checks its validity. They interact with the prover to confirm that the prover possesses the required secret information without learning the secret itself.

The verifier uses a public key or common reference string to run the verification algorithm. Their role is to provide the trustless confirmation necessary for the system to operate securely.

## Glossar

### [Cryptographic Proof](https://learn.greeks.live/area/cryptographic-proof/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Attestation ⎊ Cryptographic proof, within cryptocurrency and derivative markets, functions as verifiable evidence of state transitions or computational integrity, crucial for trustless systems.

### [Trustless Confirmation](https://learn.greeks.live/area/trustless-confirmation/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Verification ⎊ The core concept of trustless confirmation dictates that the validity of a financial transaction or a complex computation can be mathematically verified by any party using only public data.

### [Common Reference String](https://learn.greeks.live/area/common-reference-string/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Reference ⎊ Within cryptocurrency derivatives and financial engineering, a Common Reference String (CRS) denotes a standardized alphanumeric identifier employed to uniquely specify underlying assets or contracts across disparate systems and platforms.

### [Verifier](https://learn.greeks.live/area/verifier/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Attestation ⎊ Verifiers, within cryptocurrency networks and derivative markets, function as critical nodes responsible for confirming the validity of transactions and state changes, ensuring data integrity and preventing double-spending or fraudulent activity; their operation is fundamental to maintaining trustless systems, particularly in Proof-of-Stake consensus mechanisms where selection is often weighted by stake size and performance metrics.

### [Computational Resources](https://learn.greeks.live/area/computational-resources/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Processing ⎊ Computational resources, within cryptocurrency, options trading, and financial derivatives, represent the quantifiable capacity for executing complex calculations essential for market participation.
