Petname
Petname systems are naming systems that claim to possess all three naming properties of Zooko's triangle - global, secure, and memorable. Software that uses such a system can satisfy all three requirements. Such systems can be used to enhance security, such as preventing phishing attacks. Unlike traditional identity systems, which focus on the service provider, Petname systems are decentralized and designed to facilitate the needs of the enduser as they interact with multiple services.
