Blockchain systems and methods for digital ratings and secured sales of digital works of art are provided. The systems include a platform for posting art, an interface, an auction module, and an artificial intelligence unit. The platform enables artists to post digital works of art on their personal pages. The interface enables users to become followers of the digital works of art and post likes or dislikes for the digital works of art, and the platform assigns a monetary value to the like. Each digital work of art is assigned a purchase price equal to the monetary value assigned to the like multiplied by the number of likes for the first digital work of art. When a user offers the purchase price the auction module transfers payment to the first artist and the first work of art to the user. A public censure system enables deletion of the first digital work of art if the first digital work of art is determined to be offensive or inappropriate based on a pre-determined percentage of dislikes posted. If a dislike is posted for the first digital work of art, a supervisory system automatically monitors the first digital work of art and user comments related thereto, and if an inappropriate or offensive comment is detected, the supervisory system removes it.

Introduced here is a computational architecture (also referred to as a “computational infrastructure”) that addresses the limitations of traditional data management solutions using a highly secure data management solution coupled with consent-based sharing. At a high level, the computational architecture applies blockchain methodologies to both transaction data and business data such that both types of data are stored “on chain” in the same computational architecture. This enables several significant advantages over traditional data management solutions with respect to data security, data ownership, data sharing, and intelligence.

Adding additional value to NFTs is described. An association of a non-fungible token (NFT) with a user account is verified based on an address of a digital wallet that corresponds to the user account and that is encoded into the NFT stored on a blockchain. After verifying the association of the NFT with the user account, a condition relative to the NFT is detected. Responsive to detecting the condition, ownership of an earned item is conferred to the user account. An NFT collection is formed by digitally bundling the NFT and the earned item, and a listing of the NFT collection is generated for the user account. The listing specifies that the NFT collection includes both the NFT and the earned item.

Processing nodes (100) is arranged in a redundant configuration in a first blockchain (BC1), to detect generation of transaction data (D) on a first transaction in the first blockchain (BC1), and control whether to transmit a remote transaction after the first transaction to a second blockchain (BC2) based on the transaction data. For example, each processing node (100) performs a hash operation on data contents of the transaction data (D), and determines a priority order of execution of the remote transaction by each processing node (100). The remote transaction is transmitted to the second blockchain (BC2) when the priority order of a processing node A (100) is highest, transmission of the remote transaction to the second blockchain (BC2) is set to stand by when the priority order of the processing node A (100) is second highest or lower, thereby removing the need for special exclusive control in the redundant configuration.

A computer-implemented system and method to collect and store data related to product stored in a container. In response to filling the container with the product, the following data are stored in at least one first record in an external database (such as a distributed ledger, e.g., blockchain): a product type of the first product; an amount of the first product filled into the first container; a unique identity of the first container; and a unique identity of a first user of the first container at the time of filling the first container with the first product. Data representing a unique identity of a container data module on the container are stored in the container data module. As the container moves, dispenses product, and undergoes changes in possession and ownership, data representing such events are stored in the distributed ledger and/or the container data module. As a result, a verifiable application/consumption record of the product within the container is generated.
