Id Io Ip

Blockchain identity and reputation management systems. By combining blockchain with identity verification, a digital ID can be created for ecosystem participants and function as digital watermark. Such an ID can be assigned to every smart contract transaction. Suitable identity verification protocols, for example the Civic20 project, which aims to tackle the problem of consumer identity theft and reduce online identity fraud, are already available.
