Given that the trusted party is required for this to work, is there any point at all in having it depend on the Etherium blockchain, other than perhaps a weak form of anonymity network?
The purpose of killcord + ethereum for public disclosures is that leaning on ethereum as an API backend ties itself to the fact that taking down the entire ethereum network is difficult and running your own backend resiliently is hard.
That being said, I'm working on the concept of "providers" so that storage, payload, and backend can be plugable and you'll be able to use whatever backend you are comfortable with.
The trusted party can be factored into a decentralized network as well. This is what our team is working on with the Keep network (we've considered dead man switches as potential applications for a while).
