Changpeng Zhao highlighted how public blockchains like Bitcoin and Ethereum expose transaction details, using payroll as an example where salaries become visible to all. He echoed Chamath Palihapitiya's view that this transparency gap hinders crypto's use as everyday money, while businesses risk revealing sensitive data like pay disparities. Privacy projects like Monero, Zcash, and tools on Solana, Sui, and Ethereum offered solutions, though critics value transparency for fraud detection and compliance. Grayscale CEO Barry Silbert agreed it's a key unsolved issue amid growing interest in on-chain payroll and real-world assets.
