System for facilitating secure electronic communications between entities and processing resource transfers

Abstract

Embodiments of the present invention provide a system for utilizing one or more decentralized applications to allow entities to interface with a blockchain for the purposes of conducting a resource transfer. Typically, the blockchain is a permissioned blockchain which may be accessed only by the entities involved in the resource transfer. The decentralized applications may communicate with the legacy systems within each entity through an application programming interface (API) such that the data stored on the legacy systems may be governed by the blockchain. This ensures the authenticity of the data stored on the legacy systems while preventing the possibility of disparate versions of data being created over time.

What is claimed is: 
     
         1 . A system for integrating legacy systems with a blockchain, comprising:
 a communication interface;   a processor; and   a memory having a blockchain application stored thereon, wherein the blockchain application, when executed by the processor, causes the processor to:
 receive, via a blockchain dashboard, a request from a first user to access the blockchain; 
 receive authentication credentials from the first user; 
 determine, based on validating the authentication credentials of the first user, that the first user is authorized to access at least one decentralized application; 
 receive, from the user, a request to upload a data file to the blockchain, wherein the data file is associated with a first transaction; 
 detect, via a consensus algorithm, that the data file is valid; 
 append the data file to a block in the blockchain, wherein the block comprises a transaction address and a transaction ID; and 
 automatically update a legacy system with the transaction address and the transaction ID. 
   
     
     
         2 . The system according to  claim 1 , wherein the blockchain application further causes the processor to:

         3 . The system according to  claim 1 , wherein the blockchain application further causes the processor to:
 detect a status of a second user;   in response to detecting the status of the second user, determine that the second user is restricted from accessing a first decentralized application; and   display, via the blockchain dashboard, a set of decentralized applications on a graphical interface, wherein the set of decentralized applications excludes the first decentralized application.   
     
     
         4 . The system according to  claim 1 , wherein the blockchain application further causes the processor to:

         5 . The system according to  claim 1 , wherein the blockchain application further causes the processor to:
 detect that a status of the first transaction has been changed; and   display, via a graphical interface, a push notification to the first user through the blockchain dashboard.
