Abstract: The present disclosure provides an approach for a blockchain system in which (a) data of past transactions can be removed from the storage of network nodes based on node permissions, and (b) in which data can be made invisible to users based on user-specific or group-specific permissions. The blockchain system stores cryptographic proofs of data on an immutable ledger. The data itself is maintained within the blockchain system such that it can be partially or fully removed, while maintaining the integrity of the ledger.

Abstract: A method is performed by a first fog node of a plurality of fog nodes. In some implementations, the first fog node includes a non-transitory memory and one or more processors coupled with the non-transitory memory. In some implementations, the method includes maintaining a distributed ledger in coordination with the remaining fog nodes of the plurality of fog nodes. In some implementations, the distributed ledger stores configuration information associated with one or more devices. In some implementations, the method includes obtaining a request for configuration information from a device that breaches a resource threshold associated with the distributed ledger. In some implementations, the method includes transmitting, to the device, the configuration information associated with the device in order to allow the device to be configured in accordance with the configuration information while the device breaches the resource threshold associated with the distributed ledger.
