Extending blockchain to support controlled branching and consistent data reconciliation for collaborative data evolution

One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• storing a plurality of data assets on a global ledger used by a plurality of nodes in a network;
• generating a plurality of local caches including a first local cache, each local cache of the plurality of local caches being associated with a respective subset of the plurality of nodes;
• storing, by a node in a first subset of the plurality of nodes, the first subset being associated with the first local cache, a write transaction to the first local cache;
• merging the write transaction from the first local cache onto the global ledger;
• and
• responsive to determining that the node is not in communication with a majority of the plurality of nodes, copying asset dependencies from the global ledger to the first local cache.

A system comprising:

• a plurality of devices configured to write to a global ledger having a plurality of nodes, the plurality of devices including a first device, the first device having at least one processor, and the plurality of devices being configured to perform operations including
• storing a plurality of data assets on the global ledger,
• generating a plurality of local caches including a first local cache, each local cache of the plurality of local caches being associated with a respective subset of the plurality of nodes,
• storing, by a node in a subset of nodes associated with the first local cache, a write transaction to the first local cache, and
• merging the write transaction from the first local cache onto the global ledger;
• and
• applying one or more conditional authority rules to determine that the first device is permitted to perform the write transaction;
• wherein the one or more conditional authority rules are configured to grant write permission to a highest-ranked device that is in communication with a majority of the plurality of devices.

A method comprising:

• storing a plurality of data assets on a global ledger used by a plurality of nodes in a network;
• generating a plurality of local caches including a first local cache, each local cache of the plurality of local caches associated with a respective subset of the plurality of nodes;
• storing, by a node in a first subset of the plurality of nodes, the first subset being associated with the first local cache, a write transaction to the first local cache;
• and
• merging the write transaction from the first local cache onto the global ledger;
• and
• responsive to determining that the node is not in communication with a majority of the plurality of nodes, copying asset dependencies from the global ledger to the first local cache.
