maintain data integrity and share a third set of data with a fourth entity being a regulatory agency, the third set of data being shared peer-to-peer, and accessible by, only the first and fourth entities.
11 . The system of claim 1 , wherein:
when a plurality of blocks having a same block identifier as each other is received at the first node, the first node verifies the plurality of blocks and temporarily stores the plurality of blocks if they pass verification; and
the first node uses a subsequent block to determine which of the plurality of blocks is a correct or consensus block.
12 . The system of claim 1 , wherein a longest chain of blocks in the supply chain distributed ledger is retrieved following the first node going offline, each new block added since the first node has been offline is verified, and a local copy of the supply chain distributed ledger is updated.
13 . A method for controlled data sharing comprising:
