Arc has released a privacy white paper and introduced Arc Privacy, a confidential smart contract engine designed to enhance privacy in on-chain finance. This new feature aims to safeguard sensitive financial activities such as payroll processing and fund management by ensuring that transaction details remain confidential on public blockchains. Arc Privacy allows authorized parties, like auditors, to access necessary information while keeping it hidden from the public. The solution addresses the challenge of migrating real-world financial workflows to blockchain by preventing exposure of sensitive data, such as salaries and fund flows, to the market. Arc plans to support developers in creating multi-step private applications within the EVM environment in the future.
