What Are the Primary Types of ZKPs Used in Cryptocurrency Scaling Solutions?
The primary types include zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) and zk-STARKs (Scalable Transparent Argument of Knowledge). zk-SNARKs are highly efficient but require a trusted setup, while zk-STARKs are transparent and quantum-resistant but produce larger proofs. These are fundamental to Layer 2 scaling solutions like ZK-Rollups, which batch transactions off-chain and submit a single cryptographic proof on-chain.
