Definition ∞ Trusted Setup SNARKs are a type of Zero-Knowledge Succinct Non-Interactive Argument of Knowledge that requires an initial, one-time cryptographic setup phase. This setup generates a set of public parameters that are crucial for the system’s security and must be performed honestly, typically involving multiple parties to mitigate trust risks. Once generated, these parameters allow for efficient verification of complex computations without revealing underlying data. They provide strong privacy and computational integrity.
Context ∞ Trusted Setup SNARKs are a technical subject appearing in news related to advanced cryptography, blockchain privacy solutions, and scalability initiatives. The security implications of the initial setup phase, particularly the “ceremony” to generate parameters, are often discussed. Efforts are ongoing to develop more robust and trust-minimized setup procedures or to transition to trustless SNARK constructions. This technology is foundational for privacy-preserving decentralized applications.
