Why crypto's privacy problem is a total dealbreaker for mainstream users

The core issue preventing mainstream adoption of cryptocurrency is the public nature of the ledger, which mainstream users perceive as a lack of privacy and a security risk, similar to having all credit card transactions visible to neighbors. Businesses also cannot adopt public blockchains because revealing transaction details exposes proprietary supply chains to competitors. The industry needs a balance where some data is public for auditing (like regulatory compliance) and other data remains private for commercial function. The author argues that the solution lies in developing infrastructure similar to the internet's SSL encryption moment, providing a confidentiality layer. Advances like strkBTC on Starknet, which offers Bitcoin's security with a confidentiality layer for selective disclosure, demonstrate that private finance can be built on public blockchains, which is necessary for scaling and achieving global adoption.
