Zero Knowledge Proofs (ZKPs) have become crucial in blockchain applications for their ability to provide privacy, scalability, and security. Vitalik Buterin has emphasized the importance of advanced ZKP systems like Space and Time's HTAP framework or Polygon's zkEVM. Aztec is another pioneer working on a fully private L2 with Noir, a private smart contract language compatible with circuits. Projects like these are paving the way for more efficient and secure blockchains.
