Blockchains are designed for transparency so anyone can verify transactions without relying on a central authority. This public visibility ensures security, but it creates a major confidentiality problem. On public blockchains, all data wallet balances, transaction histories, and smart contract interactionsis permanently exposed. Even though users appear as wallet addresses, analytics can link those addresses to real identities and financial behavior. This means salaries, spending habits, savings, and trading positions can all be traced. For businesses, the risk is even greater: payroll, supplier payments, revenue, and strategic actions cannot be safely stored on a public chain without exposing sensitive information to competitors. Government systems like identity, healthcare, and voting also require strict privacy, making public blockchains unsuitable As a result, transparency becomes a barrier to adoption. Emerging technologies like FHE, and MPC aim to bring confidentiality to blockchains @zama
