alt Hacker NewsInternally, you don't need it, agreed. But that is centralization risk exemplified in this incident. Which isn't necessary. Every notary could be a node. It would be a lot more resilient, and it would look a lot like a blockchain (not necessarily with a crypto currency though) if you do it properly.

If every notary is a node, you need some mechanism to ensure they perform only legitimate transactions and constantly monitor them. It is easier to just have a central authority.

You can have decentralization without blockchain. A defining feature of blockchain is that each node depends on the precise ordering of prior nodes which is a huge liability if you have network disruptions, etc, in a bureaucracy.
A git repo with cryptographically signed commits solves all the same problems without the headache.
