Revocation written on blockstamp
To index correctly the blockchain, we need to know the information about the revocation blockstamp date of a given identity.
At the moment, if we find the information revoked: true
we need to parse the https://github.com/duniter/duniter/blob/master/doc/HTTP_API.md#blockchainwithleavers
and the blocks found in this url if we want to get the blockchain date of the revocation to be able to handle rollbacks.
I think it is also the case for the written on
information of a given identity (which seems to be the first document containing a given self certification written in the blockchain).
