Blockchain technology, and in other words, a distributed, decentralized record store shared across multiple participants, is the perfect technology to disrupt the heavy centralization of naming.
This is one of the few places the use of a blockchain will shine.
I highly doubt it. We’d still have a dispute process and law mandated domain transfers, so there would need to be a centralized regulator. The transparency is nice, but you do not need full blockchain for this - something like SSL’s Certificate Transparency would work much better.
But, will it actually be more secure than what is described in the article (how do you protect against sybil attack? what if there is a zero day in some piece of software in the block chain stack?)
