Can't wait to hear how the blockchain will factor into this redesign.
I mean, technically SSA data might be a legitimate use of the blockchain. I am one of the biggest opponents of the whole mess, but there are use cases for a persistent immutable data record, and social security numbers would be one of them.
Except that the numbers are also prone to change, like if it's been stolen. They're technically not supposed to be an identification code anyhow.
Right, but you can have entries in a block chain that indicate previous entries are no longer valid, or have modifications. Calculating a final state by walking through all the blocks in the chain. ( A bit like a CQRS based system can have a particular state at a point in time by replaying all events up to that point)
Doing it in such a way also makes auditing what's happened much easier since changes are inherently reflected in the chain. You want to know when (or by who if you keep that information) a record changes, it's right their in the chain.
