Even if private actors were not involved, there wouldn’t be any way to verify that the information was destroyed by a governmental department. I suppose that is a possible area where a public blockchain that broadcasts the storage and deletion of data could be useful but now everybody has stopped reading this comment so they can talk about how blockchain tech is useless. Regardless, the indefinite/temporary storage of tracking data needs to be addressed at some point.
- jstanley 8y agoHow exactly could a blockchain publish deletion of data in a way that can't be cheated?
- bochoh 8y agoThrough a private key mechanism. If there was a mechanism to automatically remove the private key for a record then it would become effectively unreadable (in our life time, anyway).
- jstanley 8y agoBut what stops you from copying the private key before it gets removed? Or running a client that just pretends to remove the private key? Half the point of a blockchain is that once data is out there it can't be removed. You can't leverage that to force the removal of something.
