The seven deadly sins of crypto privacy
Summary
Public blockchains lack privacy protection, exposing users to surveillance and coercion. Common flaws in crypto privacy tools include centralization, logging user activity, fully encrypted states, dependency on specific manufacturers, creating new privacy chains, builder complexity, and immature technology. Building on-chain privacy systems while preserving auditability and decentralization is challenging. The Web3 Privacy Now initiative provides a resource for assessing the privacy levels of crypto tools.
