Abstract
Techniques for extending blockchain to support controlled branching and consistent data reconciliation for collaborative data evolution include: storing multiple data assets on a global ledger used by multiple nodes in a network; generating a first local cache for a first subset of the multiple nodes; storing, by a node in the first subset, a write transaction to the first local cache; and merging the write transaction from the first local cache onto the global ledger.
