I've been working on a design doc (
https://github.com/araujo88/bitdc) for a second-layer implementation of a life/death verification protocol, which I named "BitDC". The basic idea is to leverage its multi-signature capabilities and integrate a proof of life mechanism through dust-transactions.
To solve the oracle problem, it proposes a redundancy and weight approach, using different methods as sources of truth and also proposes some mechanisms for collusion prevention for forging one's own death. One of this methods is to use pre-selected and random verifiers for signing a multi-signature wallet to confirm the death of an individual.
The issue with current methods that use "blockchain" for certificates is that the issuers are centralized authorities, as in MIT's Blockcert for example. This protocol main objective is to solve this problem and descentralize the whole process.
I would appreciate any help/feedback on developing this idea further.
