Abstract: A method or a system for validating digital ownership in immutable databases via physical devices. The system receives a request for accessing a secure resource from a client device of a user of an immutable database, and requests a wallet address associated with a wallet of the user from the client device of the user. Responsive to receiving the wallet address, the system requests an identifier (ID) token from the immutable database based on the wallet address, the ID token containing a first set of identity data of the user. The system also requests a second set of identity data from the client device. The system compares the first set of identity data with the second set of identity data to determine whether there is a match. Responsive to determining that there is the match, the system grants the user a permission to access the secure resource.

Abstract: A method and/or a system for synchronizing data across immutable and mutable data storage systems. The system provides an endpoint configured to receive messages associated with database actions from client devices. Responsive to receiving a message associated with a database action via the endpoint, the system routes the message to an action queue. The system transmits the message from the action queue to multiple data engines corresponding to multiple data storage systems that store data, causing the multiple data engines to perform the action based on the message. The multiple data engines include a mutable data engine corresponding to a mutable data storage system and an immutable data engine corresponding to an immutable data storage system. The system tracks the action queue to determine an action performance speed of each data engine.

Abstract: Disclosed herein are systems, media, and methods of applying machine learning to create a digital request for proposal for use in property construction and improvement. Consumers are enabled by the systems, media, and methods disclosed herein to compose property improvement proposals and generate electronic documentation to assist contractors in evaluating said proposals and providing bids for the completion of the proposed property improvement.
