Claim 5:
6. A system that implements a secure and decentralized network, the system comprising:
a first bank node of a distributed ledger network, wherein the distributed ledger network is communicatively coupled to a first in-bank system;
a second bank node of the distributed ledger network, wherein the distributed ledger network is communicatively coupled to a second in-bank system; and
an interbank information network that is layered on top of the distributed ledger network, wherein the interbank information network establishes a direct communication channel between the first node and the second node, wherein the interbank information network encrypts each communication sent between the first and second nodes and further sends a decryption key for each communication in a separate communication from the encrypted communication after authorizing the intended recipient node, wherein the interbank information network obtained the decryption key from a secured key-vault, and
wherein the first bank node is configured to:
secure a connection to the distributed ledger network via an application programming interface (API), and wherein the secure connection to the distributed ledger network applies a two-way Secure Sockets Layer (SSL) for a web-interface and the API;
receive inquiry activity comprising payment instructions to make a payment to a second bank node that is part of the interbank information network;
check, through a blockchain node for the first bank node, permissions for the payment instructions;
validate, through the blockchain node for the first bank node, permissions for the payment instructions;
obtain consensus on the distributed ledger network associated with the interbank information network, through the blockchain node for the first bank node, for the payment instructions;
record and publish, through the blockchain node for the first bank node, a hash that represents the inquiry activity, onto a public ledger for the distributed ledger network associated with the interbank information network;
send one or more private inquiry details comprising a request message to the second bank node over the distributed ledger network;
receive, from the second bank node, a response to the request message over the distributed ledger network, wherein the second bank node receives the request message, processes one or more transaction details and generates a response; and
process a payment pursuant to the payment instructions and responsive to the response to the request message,
wherein the inquiry message comprises a message that requests the second bank node to share client data and the client data comprises an account open date and name matching conditions.
