Introduction to ZKPs
Zero-knowledge proofs allow one party to prove to another that a statement is true without revealing any information beyond the validity of the statement itself.

zK-SNARKs vs zK-STARKs
zk-SNARKs are more efficient but require a trusted setup, while zk-STARKs are transparent and quantum-resistant but larger in size.

Applications in Blockchain
ZKPs are used for scaling solutions like rollups, enabling thousands of transactions per second while maintaining security and privacy.
Zero-knowledge proofs represent a key innovation for blockchain scalability and privacy, with distinct trade-offs between the different implementations.
