Abstract
A computer-implemented method of providing data governance as data flows within and between networks, comprising: accessing, by a second gateway computing device, data stored in a plurality of hash chains in a hierarchy of digital ledgers and written by a plurality of first gateway computing devices, wherein validity of the data stored in the plurality of hash chains has not been verified prior to writing; detecting, by the second gateway computing device, consensus of the data stored in the plurality of hash chains by comparing each of the plurality of hash chains to all other hash chains of the plurality of hash chains to determine whether the hash chains are cryptographically consistent; in response to detecting consensus of the data stored in the hash chains, updating, by the second gateway computing device, stored blockchain data using the data stored in the plurality of hash chains.
