Andreessen Horowitz's a16z crypto has highlighted a common misconception among developers who equate "ZK" with "succinctness" rather than true zero-knowledge privacy. In a recent blog post, a16z crypto noted that most zkVMs require an expensive "wrapping" process to achieve genuine zero-knowledge features. To address this, the firm announced the integration of the NovaBlindFold folding scheme into the open-source Jolt zkVM. This upgrade allows the system to generate hidden proofs without revealing input data, supporting privacy applications. The new zero-knowledge proofs are only about 3 KB larger than the original non-ZK proofs.
