We are building an open security protocol for the Internet storing trust and reputation information about Uniform Resource Identifiers (URIs) including domain names, applications, bots, crypto wallet addresses, Application Programming Interfaces (APIs), and content classification. The Protocol’s registry is machine-readable and queryable for use by Internet Service Providers (ISPs), routers, crypto exchanges, Wi-Fi hotspots, mobile devices, browsers, websites, and applications to help address cyber threats such as phishing, malware, brand protection, child safety and news credibility.
