Non-Interactive ZK Proofs (NIZK): These proofs do not require interaction between the prover and the verifier. They are more efficient and are the backbone of most ZK P2P Payment systems.
Succinct ZK Proofs: These proofs are compact and require minimal computational resources, making them highly practical for real-time transactions.
The Mechanics of ZK P2P Payments:
When Alice wants to send Bob some cryptocurrency using ZK P2P Payments, the process unfolds as follows:
Preparation: Alice initiates a payment request. Instead of revealing her wallet address, amount, and other details, she generates a cryptographic proof that she possesses the required funds.
Generation of Proof: Using her private key, Alice creates a ZK proof that she has the funds without revealing any specifics of the transaction. This proof is mathematically verified and can be shared securely.
Verification: Bob receives the proof and verifies it using a verifier algorithm that checks the validity without needing to know the specifics of the transaction. This step ensures that Alice indeed has the funds for the transaction.
Completion: Once verified, the transaction is completed. The funds are transferred, and a record is added to the blockchain, maintaining transparency without compromising privacy.
