Polygon Labs has launched Privado ID, an independent protocol-agnostic service that offers a self-sovereign identity control solution. The service can be used for a variety of purposes including proving humanity and uniqueness, implementing airdrops, trading on decentralized exchanges, and fulfilling compliance procedures. Privado ID can also be used in traditional finance for the transfer of tokenized assets. The service offers cryptographic-based zero-knowledge technology, which prevents information from being stored or passed on by a third party. Privado ID has already undergone proof-of-concept with multinational banks and financial institutions.
