Wu Shuo learned that Arc has released a privacy white paper, proposing an optional privacy (Opt-in Privacy) solution for on-chain finance, planning to provide confidentiality support for scenarios such as payroll, corporate treasury management, transaction processes, asset issuance, and inter-company payments and foreign exchange settlements, under the premise of ensuring visibility for authorized parties. Arc stated that sensitive financial activities should not become public market data, and its goal is to enhance on-chain financial transaction privacy while meeting compliance and audit requirements.
