Initialization: Alice and Bob agree on a secure protocol to initiate the exchange. They both input their respective amounts of fiat currency and Bitcoin.
Zero-Knowledge Proof: Alice generates a zero-knowledge proof (ZKP) that confirms she has the necessary fiat currency without revealing the exact amount or details of the transaction. Bob can verify this proof without seeing the actual transaction details.
Exchange: With the verification complete, Alice and Bob exchange their currencies. The ZKP ensures that both parties fulfill their part of the transaction without revealing any private information.
Completion: Once the exchange is complete, the transaction is recorded on a blockchain, ensuring transparency and security.
Advantages of ZK-p2p Private Exchanges

Deep Dive into Zero-Knowledge Proofs
What is a Zero-Knowledge Proof?
At its core, a zero-knowledge proof (ZKP) is a method by which one party (the prover) can prove to another party (the verifier) that a certain statement is true, without revealing any information apart from the fact that the statement is indeed true. This is achieved through a series of interactions between the prover and the verifier.
How Does It Work?
Imagine you want to prove to someone that you have a secret number without revealing the number itself. Here’s a simplified version of how it works:
Statement Verification: The prover starts with a statement they want to verify (e.g., “I have enough fiat currency to exchange for Bitcoin”).
Proof Generation: The prover generates a proof that the statement is true without revealing any details about the statement itself. This proof is cryptographically secured.
Verification: The verifier can then use this proof to verify the statement’s truth without gaining any insight into the statement’s specifics.
Interaction: The prover and verifier engage in a series of questions and answers that validate the proof without revealing the underlying data.
Technical Aspects of ZK-p2p
Cryptographic Protocols
