Understanding ZK Protocols and Their Significance
At the heart of ZK (Zero-Knowledge) protocols is a groundbreaking concept. It’s called zero-knowledge proofs(ZKPs). This method lets one person prove something to another without sharing extra details. It’s key for keeping data private and secure in online systems.
What are Zero-Knowledge Proofs (ZKPs)?
Zero-knowledge proofs are a new way to share information without giving away too much. One person can show that a statement is true without sharing the details. This keeps the data and the process secret.
Types of ZK Protocols: zk-SNARKs and zk-STARKs
There are two main types of ZK protocols: zk-SNARKs and zk-STARKs. zk-SNARKs are fast and have small proof sizes, perfect for high-performance apps. But, they need a trusted setup, which can be a problem. zk-STARKs don’t need a trusted setup, making them more scalable and transparent, but they have bigger proofs.
ZKPs have evolved from zk-SNARKs to more advanced versions like zk-STARKs and PLONK. Each new version aims to fix the old ones’ flaws. These updates have made ZK protocols popular in Web3, including privacy-focused blockchains and DeFi.
