Abstract: Systems and methods for blockchain-based data-driven property management are disclosed. In one embodiment, a method for blockchain-based data-driven property management may include: (1) receiving, by a property management computer program, title information for a property from a title recordation office; (2) validating, by the property management computer program, the title information with an owner of the property, a lienholder of the property, and/or a recorder of the title information; (3) recording, by the property management computer program, the title information to a distributed ledger, wherein a consensus algorithm executing on nodes in a distributed ledger network update the distributed ledger with a block comprising the title information; (4) periodically polling, by a first smart contract, the title recordation office for updated title information for the property. (5) automatically notifying, by the first smart contract, an interested party of the updated title information.

Abstract: For a number of users is a system provided to create, edit, replay and view documents of free hand drawn sketches. The system captures the creation process together with verbal and/or visual information provided by each user and automatically correlates them for a later synchronized replay. The system provides a number of tools and features, mainly to: combine the sketching activity with existing images, to selectively retrieve media information correlated to individual sketch entities and to quasi simultaneously collaborate at a common document. The system architecture can by adjusted to various parameters in the communication infrastructure. The system may be implemented in any software program, a web based service, a web browser, an operating system for computers and/or communication devices.
