Database access gateway through distributed network nodes

A system comprising:

• a plurality of distributed network nodes, each network node having a non-transitory storage medium storing a plurality of computer program instructions forming a peer-to-peer client and a processor electrically coupled to the non-transitory storage medium and configured to execute the plurality of computer program instructions to perform one or more operations of a private party blockchain hosted by the plurality of distributed network nodes;
• the private party blockchain configured to validate one or more database operations of a plurality of secure databases of different types interfacing the plurality of distributed network nodes, wherein the plurality of secure databases is external to the private party blockchain, and wherein the plurality of distributed network nodes defines an access gateway in communication with the plurality of secure databases;
• a first subset of the plurality the distributed network nodes configured to be validator nodes causing the corresponding processors to execute corresponding peer-to-peer clients to gossip with each other to co-operatively validate the one or more database operations and generate a new block;
• and
• a second subset of the plurality of distributed network nodes configured to be host nodes causing the corresponding processors to execute corresponding peer-to-peer clients update the corresponding local copies of the private party blockchain appending the new block generated by the validator nodes.
