Thanks for a very useful and clear checklist! Would you say decentralized DNS checks all those boxes (Namecoin is a thing, after all)? Why would a DNS require the notion of transaction?

I'm aware of sites that tell you whether you need a blockchain or not for your application, but they don't say what to use if only one or two of the requirements for a blockchain are not needed. What would a decentralized DNS strictly need if the notion of transaction wasn't required (but only the latest value)?

Actually DNS would benefit from transactions, it would allow to detect attack much more efficiently, or to analyze them after the fact.

It could also help analyze tendencies and adjust.

And as usual, you would get more accountability, which never hurts (Steven ! Why is the website down ? - * Steven quickly revert back his silly click * - Errr, nothing. No reason. Everything is alright !)
