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

> Computer scientist Nick Szabo's paper "Secure Property Titles with Owner Authority" illustrated that all three properties can be achieved up to the limits of Byzantine fault tolerance.

> Activist Aaron Swartz described a naming system based on Bitcoin employing Bitcoin's distributed blockchain as a proof-of-work to establish consensus of domain name ownership. These systems remain vulnerable to Sybil attack, but are secure under Byzantine assumptions.

> Several platforms implement refutations of Zooko's conjecture, including: Twister (which use Swartz' system with a bitcoin-like system), Blockstack (separate blockchain), Namecoin (separate blockchain), LBRY (separate blockchain and peer-to-peer file-sharing), Monero OpenAlias and Ethereum Name Service.
