Prometheus metrics
- Discussion of legal issues
- GDPR: https://sovrin.org/gdpr-position-paper
- Tombstones
Tombstones are transactions that mask data on a ledger without altering previously written data to the ledger. Essentially, a ‘GDPR’ request requires that personal data be removed from a ledger, however, data can’t be removed from immutable ledgers while still maintaining the integrity of the ledger. To compensate for this dilemma, ‘tombstones’ can be written to ledger nodes, such that when read requests for ‘retracted’ ledger blocks are made, the node returns a tombstone (blocked request) instead.
It’s up to individual nodes to add a tombstone or not. IOW, a node in Germany may return a tombstone on a retracted block. However, another node in Canada may return the original data. This is another dilemma…
Individual nodes can tombstone data: https://jira.hyperledger.org/browse/INDY-2082
