Blockchain technology has arguably progressed to the point that Zooko's triangle can be solved.
If you're interested in learning more about a project that is giving this a stab, check out Handshake.[0]
Here are some notes from a Handshake developer about Zooko's Triangle.
> Handshake is a decentralized, permission-less naming protocol compatible with DNS. We seek to solve Zooko's triangle through the use of a utxo-based blockchain, which manages the registration, renewal, and transfer of DNS top-level domains (TLDs). The initial goal is not to replace the DNS protocol but to replace the root zone file and the root servers with a decentralized, public commons. By tying name ownership to a utxo, and embedding DNS records into its metadata, a chain of trust can be created by a digital signature and verified by querying blockchain data. A decentralized network of validating peers anchors this chain of trust. The ultimate goal is to provide an alternative to existing Certificate Authorities.[1]
