The blockchain.

The only thing a blockchain is good for is achieving decentralized consensus on what value a key points to, which is what DNS is.

An alternative way of looking at this is that acquiring domains must be somewhat expensive by definition; either you enforce it at the system level, or you make it free, but then somebody will inevitably grab all the interesting ones and re-sell them to others. A blockchain is the only way to make decentralized financial infrastructure viable.
