Zero Knowledge Proofs (ZKPs) are a cryptographic method that allows one party (the prover) to prove to another party (the verifier) that a statement is true, without revealing any information beyond the validity of the statement itself. This concept is significant in blockchain and privacy-focused applications, enabling transactions and interactions where privacy and security are paramount.

In the context of blockchain, ZKPs can be used for confidential transactions, where the details of the transaction (such as the amount and the parties involved) are obscured, while still being verifiable by the network. This technology underpins privacy-centric cryptocurrencies and allows for secure, anonymous transactions without sacrificing the integrity and security of the blockchain.

Zero-knowledge protocols must adhere to the following three criteria:
1. Completeness: If a valid input is submitted, a zero-knowledge protocol must always return "true".

2. Soundness: Valid inputs should be impossible to trick zero-knowledge protocols to return "true".

3. Zero-knowledge: Verifiers should not be able to derive the original input and cannot learn anything about a statement beyond its validity or falsity.

There are two types of zero-knowledge proofs including Zero-Knowledge Succinct Non-Interactive Argument of Knowledge (ZK-SNARKs) and Zero-Knowledge Scalable Transparent Argument of Knowledge (ZK-STARKs).

ZKPs offer a powerful tool for enhancing privacy and security in a wide range of applications, from digital identity verification to secure voting systems, by enabling verification without exposing sensitive information. Their integration into blockchain technology represents a significant advancement in the pursuit of combining transparency with privacy.
