Email issues: There are no results for Just like all public state transitions (including deletes) are stored in the peer's block store, all private data state transitions (including deletes) are stored in the peer's private data store. The peer's private data store ensures that listeners and other peers that may be catching up at lower heights can retrieve the private data that they need. You are correct that only the blockToLive policy will purge the private data from the peer's private data store. Others have also requested an on demand delete from both private state and private data store, and as a result we created enhancement request https://jira.hyperledger.org/browse/FAB-5097 which you can vote for and watch in Jira. Solutions that want more control over private data often prefer to hash the data prior to submitting it to Fabric, rather than having Fabric disseminate it through the private data feature. |
