System and method for prevention of counterfeiting of products using combination of packaging codes and blockchain technology is provided. Hash of a first product code is generated by encrypting scanned product data associated with a product received. Second product code is generated by encrypting first product code for combining with distinct first product code Quick Response (QR) part values. Hash of a third product code is generated by combining hash of first product code and hash of second product code. Hash of third product code is divided into a hash of a first sub-code and a hash of a second sub-code. Lastly, a comparison of a scanned third product code placed on the product is performed with requested user ID, generated hash of first product code, second product code and hash of third product code to ascertain a match therebetween for preventing counterfeiting of the product.

A method and system for regulating power consumption on an electric power grid is disclosed. Blockchain miners are used as a load bank that can be modulated quickly to accommodate spikes or dips in power generated from wind and solar power producers. The cryptocurrency generated by the blockchain miners allows electric grid owners to recoup the costs of higher overall power production, and accommodates fluctuations that are characteristic of wind and solar power generation devices because the fluctuations from wind and solar devices can be matched by modulating the computational speed of the blockchain miners in equal amounts, thus matching the overall demand and production of the power on the electric grid.

The present disclosure relates to configuring computing nodes in a distributed ledger environment (e.g., a blockchain environment). Smart contracts and blockchains are used in a wide variety of application fields. Conventionally, smart contracts are executed on a general-purpose computer, which often underperform for a variety of tasks associated with implementing a blockchain network. The present disclosure describes a novel smart contract system implementable on nodes of a blockchain network in order to provide improved or optimized performance. For example, the smart contract system can leverage instruction-level parallelism as well as transaction-level parallelism during smart contract processing in order to boost its execution performance. Further, the smart contract system can be configured and adapted to different workloads in order to remove bottlenecks. The processes described herein can additionally be implemented on unique hardware uniquely suited for the parallelism involved in processing blockchain transactions.

Each luxury item is provided with a unique indicium that is formed by a QR code with an embedded NFT. The NFT is minted and stored using blockchain technology. The indicia thus provide both the benefit of being easily scanned and the uniqueness that cannot be reproduced without detection. The indicium is attached to each item, whether by a permanent or non-permanent tag. In some instances, the indicia can be embedded into the surface ornamentation of the item. During the initial sale of the item, the indicia is scanned, and ownership of the item updated in the blockchain. During subsequent transactions of the same item, the indicia can be scanned again thus allowing the authenticity of the good to be verified and the ownership updated. The indicia can be created by the manufacturer of the goods or by a third party.

A smart contract-based AR resource quality management may establish a collaboration agreement between a provider device and a consumer device. The consumer device may indicate multiple quality requirements for the AR resources in a request. The provider device may receive the request and generate a smart contract based on the request. The provider device may generate and transmit the AR resources to the consumer device based on the smart contract. The AR resources may be of a first type (e.g. raw resources and/or sensory data) and/or may be of a second type (e.g. processed sensory data). The consumer device may receive and evaluate a quality of the AR resources. The consumer device may generate and transmit a quality evaluation result. The smart contract may be executed based on the quality evaluation result.

A system and computer-implemented method of processing a blockchain transaction request. The method comprises initiating, by an application, a blockchain transaction request; transferring, from the application to a specific node of the blockchain, a token request relating to the transaction request and including a hash-based signature associated with the application, and transferring, from the specific node to an authenticator, the token request. The authenticator receives the token request and attempts to verify it. Upon verifying the token request, it generates a token using a private key associated with the application and transfers the token to the specific node. The token is transferred from the specific node to the application and embedding, by the application, the token in the transaction request. The transaction is signed by the application to generate a signed transaction, and the signed transaction is transferred to the specific node for progressing its execution the blockchain.

The present invention relates to mass fund raising for innovations, including distributing proposals having a description of a project thought, an amount of funds requested, and a time range for raising the funds. The ownership of the project is transferred to or between entities that receive the funds from the investor, and for each of the received funds, convert the funds to a corresponding amount of virtual money, perform blockchain operations on the money, and add the funds to the funds. A blockchain operation is performed on the virtual currency to uniquely identify and track the virtual currency, thereby establishing a confidence for transactions between the investor and the entity or between the entities. If the financing target is completed within the time range, the entity converts the currency to a legal currency and releases money to the requester. After completion of the project, one or more entities determine whether the project is successful and may commercialize the successful project. For certain successful items, the one or more entities may also allocate funds to the investor.

Embodiments described herein provide for a healthcare ecosystem of computing devices participating as nodes of a distributed ledger (e.g., blockchain). The distributed ledger includes NFTs representing corresponding patients, where the initial NET behaves logically as a token scaffold that represents a “digital twin” of the particular patient. The initial patient token represents personal profile data of patient personal data for the patient. The nodes may generate new data and/or new sub-tokens (or other blockchain entry type) representing new data, which the nodes associate with the token scaffold. The sub-tokens contain data for representing physical or digital specimens, health data, and data derived from the health data (e.g., cell lines, organoids, other model systems). As the nodes generate and associate new sub-tokens to the patient's token scaffold over time, the token scaffold graphs and facilitates integration of patient-specific data and evolves into a robust electronic health record (EHR) and digital twin.
