Petname
security-enhancing software naming system

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.
History
Though the Petname model was formally described in 2005 by Mark Stiegler, the potential of the system was discovered by several people successively.
Examples
The GNU Name System (GNS) – a decentralized alternative to DNS based on the principle of a petname system
CapDesk – a distributed desktop environment
Petname Tool (discontinued browser extension) – There was a browser extension available for Firefox called Petname Tool that allowed pet names to be assigned to secure websites. Use of this extension could help prevent phishing attacks.
PetName Markup Language
The PetName Markup Language (PNML) is a proposal for embedding Petname information into other systems using a custom markup language.
“Petname” enters the record as security-enhancing software naming system. Crown Archives preserves that source wording while asking what Petname, security-enhancing and software can confirm, complicate or overturn.
Why this record matters
“Petname” is worth following because a concise public description often conceals a longer documentary argument. Here, Petname, security-enhancing and software provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jan 20, 2026. The linked authority identifier is Q7178469. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2005.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
