A single-tier blockchain-based method for document transformation and accountability is provided. Document templates relating to a transfer of real property are maintained. Each template includes a plurality of form elements each associated with a data field identifier. A subset of the document templates are collected as transaction documents for a transaction regarding the transfer of real property. The form elements of the transaction documents are populated with received data values via the data field identifiers of the form elements. Compliance checking is performed on the populated data values of the transaction documents. A cryptographic hash of the transaction documents is provided to a single tier of network nodes. The cryptographic hash of the transaction documents is committed to a blockchain copy stored by one or more of the network nodes in the single tier and the transaction documents are stored.

Asset-based investment product can be created out of any activity or asset that may generate income. These securities can be created out of any movable or immovable property, tangible assets, or intangible assets such as NFTs. Such an investment product can focus on long-lasting value classes of assets, such as real estate, as long as they can generate income and/or are subjected to long-lasting value appreciation or sustainability. In at least one embodiment, such an asset-based investment product will only pool “safe parts” of assets, can create “safe part tokens” or their equivalent out of these assets, and can offer senior tranches level to investors acquiring those “safe part tokens.” These senior tranches may be rewarded more than junior tranches after the “safe part” of each of the underlying assets has been bought, described, and registered in the blockchain owned or used by the asset holder or its beneficiaries.

The invention provides a secure method for exchanging entities via a blockchain. The invention incorporates tokenisation techniques, and also techniques for embedding metadata in a redeem script of a blockchain transaction. Embodiment(s) provide a method of: generating a first script, the first script comprising: a first set of metadata associated with a first invitation for the exchange of a first entity by a first user, the first set of metadata comprising an indication of the first entity to be offered for exchange and a first location condition for the exchange, a first user public key (P1A) associated with the first user, wherein the first user public key (P1A) is part of an asymmetric cryptographic pair comprising the first user public key (P1A) and a first user private key (V1A). The script may further comprise a first third-party public key (P1T) associated with a first third-party, wherein the first third-party public key (P1T) is part of an asymmetric cryptographic pair comprising the first third-party public key (P1T) and a first third-party private key (V1T) The method further comprises the steps of hashing the first script to generate a first script hash and publishing the first script and the first script hash on a distributed hash table (DHT).

A graphical user interface including an interactive graphical component representing a seller's offer to sell a property and at least one offer to purchase a property. The interactive graphical component including, for the at least one offer to purchase the property, a first polygon extending from an axis to represent a net offer price and a second polygon extending from the axis to represent a point value. The point value being generated by a model using a plurality of offer inputs. The graphical user interface, responsive to receiving at least one updated offer associated with the at least one offer to purchase the property, includes an updated graphical component with a first revised polygon representing the updated point value in a position of the second polygon to represent the point value for the at least one updated offer.

Two sets of data, each containing property listings, are obtained from two discrete merchant platforms. Each property listing in a set of data of a first merchant is sequentially paired with each of the property listings in a set of data of a second merchant. For each pair, each image of the property listing of the first merchant is compared to each image of the property listing of the second merchant, and images of statistically sufficient similarity are identified. The similarity of images, and in particular, of similar images likely to be rooms of the property, are considered in a determination of whether the product listings of the first and second merchant are for the same cross-listed product.

A computer-implemented and interactive real estate contract generation and editing process that allows a user to select “easy” or “do-it-yourself” contract formation sessions, comprising the steps of communicatively coupling a first electronic computing device to a computer server over a wireless communication network and generating a digital graphical user interface (GUI) on an electronic display of the first computing device with a plurality of digital data input fields operably configured to receive alpha-numeric text; initiating a network-based remote “easy” contract formation session that includes selecting a plurality of GUI icons and inputting contract formation data into each of the plurality of digital data input fields; and generating a digital document with a plurality of independent preformed paragraphs each having at least one fillable contract data field disposed therein and filled in with one of the plurality of digital data input fields to create a finalized digital document.

An apparatus, including a central computer, including a processor, database, and transmitter, and a distributed ledger and blockchain system. The central computer receives a search request, processes information contained in the search request, generates a search report, and transmits the search report to a user device. The central computer processes information to allow a user or the user device to obtain information regarding the asset from an external computer, allows the user to communicate with a counterparty device via a chat room or video conference, creates a transaction matter record for with the asset, and records activity in the chat room or records the video conference. The apparatus stores information regarding the asset, information regarding a communication between the user and counterparty, or information regarding the information recorded in the chat room or information regarding the video recording, in the database and in the distributed ledger and blockchain system.

A system for bridging between centralized and decentralized systems such that an owner can access equity in their property and a purchaser can have a high degree of confidence in the property rights being purchased. The system includes an equity conversion computer having software executing thereon to intake property information and property conversion software executing thereon to convert the real property rights to be collateralized into tokens to be registered on blockchain (decentralized system) and on government computer systems (centralized systems). The software intakes the information, saves the information in a usable format and generates various documents in formats usable by the various system the equity conversion computer communicates with. The tokenized property rights can then be converted to a crypto currency by a purchaser desiring to purchase the property rights associated with the tokens.

A method implemented on an electronic computing device for viewing and adjusting cash flows related to a building purchase includes receiving information regarding origination points and destination points for the cash flows. An icon is rendered on a display screen of the electronic computing device for each of the origination points and destination points. Connection lines are rendered between a plurality of the origination points and destination points. Each of the connection lines represents a cash flow between one of the origination points and one of the destination points. A change is detected in a connection of one of the connection lines to a different one of the origination points or to a different one of the destination points. As a result of the change in the connection, a cash flow between end points of the one of the connection lines is updated and displayed on the display screen.

Systems and methods for displaying one or more submissions are described. One such exemplar method includes: (i) accepting, from a client device associated with a reviewer, a representation of the reviewer's presence at a represented location; (ii) receiving location coordinates of a location-enabled device when the reviewer represents being present at the represented location and the location-enabled device is proximate and/or in possession of the reviewer; (iii) deeming the reviewer as an authorized reviewer of the represented location if the location coordinates of the location-enabled device are within a predefined threshold area around the represented location when the reviewer represents being present at the represented location; and (v) causing to be displayed, on one or more of the client devices, one or more submissions relating to the represented location received from the authorized reviewer of the represented location.
