The Ethereum layer 2 Aztec Network developers have introduced a whistleblowing platform named StealthNote for employees to anonymously speak out against their employers. StealthNote uses zero-knowledge proofs to confirm the authenticity of posts without disclosing personal information. Aztec Labs developer Saleel Pichen detailed the process involving Google JSON Web Token for verification. Workers from various organizations including Ethereum Foundation, StarkWare, Scroll, as well as universities like Columbia and Cornell, have utilized StealthNote to express support for privacy solutions. Ethereum co-creator Vitalik Buterin emphasized the importance of zero-knowledge proofs in addressing privacy concerns amidst increasing data security and government surveillance threats. Aztec Network, focusing on privacy, secured $100 million in Series B funding, led by Andreessen Horowitz, A Capital, and King River.
