Abstract
In some embodiments, systems, methods, and devices disclosed herein enable trusted sharing of private data and/or transactions via a distributed ledger, while maintaining data consistency properties. Some embodiments provide and utilize one or more independent and/or dependent channels. In particular, in some embodiments, one or more independent and/or dependent channels can exist on a single distributed ledger, wherein participants or nodes that are members of a particular channel can view and access the information in a given network transaction. To other participants or nodes not on the particular channel, however, only an encrypted or redacted version of the information can be viewable, thereby not disclosing the transaction information to such participants or nodes. In some embodiments, consistency properties may be preserved even in the presence of selective sharing of transaction information with proofs of validity.
