Cointelegraph reported that Polygon has launched a 'Private Stablecoin Payment' feature that uses zero-knowledge proof technology to hide the sender, recipient, and transaction amount from external viewers. Previously, companies have hesitated to enter the on-chain space due to the transparency of blockchain, where their financial flows are broadcast in real-time to competitors or the market. Polygon's new solution is key to providing selective transparency, allowing transaction details to be hidden from the market while still enabling audit files to be submitted to regulatory authorities.
