Zooko's triangle

Zooko's triangle is a diagram of three properties that are generally considered desirable for names of participants in a :

Zooko Wilcox-O'Hearn conjectured that no single kind of name can achieve more than two. For example: DNSSec, offers a secure, human-meaningful naming scheme, but is not secure against compromise by the root; .onion addresses and bitcoin addresses, are secure and decentralized but not human-meaningful; and I2P, uses name translation services which are secure (as they run locally) and provide human-meaningful names - but fail to provide unique entities when used globally in a decentralised network without authorities.

Several systems which exhibit all three properties of Zooko's triangle have now been created, including:

Several platforms implement refutations of Zooko's conjecture, including: Twister (which use the later Aaron Swartz system with a bitcoin-like system), Blockstack (which can run on any blockchain and currently uses Bitcoin), Namecoin (separate blockchain), and OpenAlias.
