Claim 15:
16. A method that implements a secure and decentralized network, the method comprising:
securing a connection to a distributed ledger network via an application programming interface (API), wherein the secure connection to the distributed ledger network applies a two-way Secure Sockets Layer (SSL) for a web-interface and the API, wherein an interbank information network is layered on top of the distributed ledger network, and wherein the interbank information network encrypts each communication sent between a first and second node of the distributed ledger and further sends a decryption key for each communication in a separate communication from the encrypted communication after authorizing the intended recipient node, and wherein the interbank information network obtained the decryption key from a secured key-vault;
receiving, at a first bank node, inquiry activity comprising payment instructions to make a payment to a second bank node that is part of the interbank information network, wherein the first bank node is communicatively coupled to a first in-bank system;
checking, through a blockchain node for the first bank node of the distributed ledger network associated with the interbank information network, permissions for the payment instructions;
validating, through the blockchain node for the first bank node, permissions for the payment instructions;
obtaining 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;
recording and publishing, 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;
sending, to a second bank node, one or more private inquiry details comprising a request message over the distributed ledger network, wherein the second bank node is communicatively coupled to a second in-bank system and wherein an interbank information network establishes a direct communication channel between the first node and the second node;
receiving, 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
processing 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.
