Halo 2 SNARKs

Definition ∞ Halo 2 SNARKs are a specific type of Succinct Non-Interactive Argument of Knowledge (SNARK) proof system. SNARKs are cryptographic tools that allow one party to prove the correctness of a computation to another party without revealing any information beyond the validity of the statement itself. The “Halo 2” designation indicates a particular iteration or variant of this technology, often optimized for efficiency and usability in specific blockchain applications. These proofs are crucial for privacy and scalability.
Context ∞ Halo 2 SNARKs are prominently discussed in the context of scaling solutions for blockchains, particularly for zero-knowledge rollups. Their efficiency in proof generation and verification is key to enabling higher transaction throughput and lower fees on networks like Ethereum. Ongoing development and adoption by various projects signal their growing importance for achieving practical scalability and privacy features in decentralized systems.
