How 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.
