Petname systems are naming systems that claim to possess all three naming properties of Zooko's triangle - global, secure, and memorable.[1] Software that uses such a system can satisfy all three requirements. Such systems can be used to enhance security, such as preventing phishing attacks.[2] 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.[3][4]

History

Though the Petname model was formally described in 2005 by Mark Stiegler, the potential of the system was discovered by several people successively.[3]

Examples

PetName Markup Language

The PetName Markup Language (PNML) is a proposal for embedding Petname information into other systems using a custom markup language.[4]

PNML consists of two tags:
