Methods and systems for controlling access to resources. Receiving, at a server from user devices, requests associated with a resource. Transmitting, by the server to the user devices, tickets associated with the requests, each ticket associated with a respective one of a plurality of groups, the groups identifying requests received in successive windows of time. Receiving, at the server from one of the user devices, a subsequent request, the subsequent request identifying one of the tickets previously transmitted to that user device. Determining that the identified one of the tickets should be accepted and the subsequent request should be serviced.

An online agricultural system manages and optimizes interactions of entities within the system to enable the execution of transaction and the transportation of crop products. The online agricultural system accesses historic and environmental data describing factors that may impact crop product transactions and/or transportation to determine market prices for crop products and crop product transportation. Responsive to receiving a request from an entity, the online agricultural system determines an optimal transaction for the entity, such as a price for selling a crop product, an available crop product for purchase, or a transportation opportunity to transport a crop product.

A producer may supply amounts x.sub.i of a good to a plurality of consumers C.sub.i in a series of transactions and be subject to a mass balancing verification protocol after every K transactions. A producer platform may compute K random shares (r.sub.1 through r.sub.K) of a random value r, publish blinded amounts t.sub.i representing x.sub.i+r.sub.i to a secure, distributed transaction ledger, and transmit an encrypted r.sub.i to consumer C.sub.i using an asymmetric cryptosystem. A consumer platform may receive and decrypt r.sub.i (while the consumer Ci actually receives an amount {circumflex over (x)}.sub.i of the good from the producer), compute {circumflex over (x)}.sub.i+r.sub.i and generate a fraud alert signal if it differs from the published t.sub.i. The consumer platform may also transmit an encrypted rolling sum value to a next consumer C.sub.i+1. A verifier platform may, after K transactions, execute the mass balance verification protocol to determine a total amount of the good that the producer had collectively supplied to the consumers C.sub.i. The verifier platform may also generate a fraud alert signal when appropriate based on the total amount and a maximum allowed amount.

A method, apparatus, and computer-readable medium for leveraging real-time sales volume for conducting group buys comprising initializing a sale of an item, the sale specifying a current price of the item which is calculated based on a current sales volume of the item and sales volume ranges, processing transactions with users for items at a purchase price equal to the current price when a purchase request is received from the corresponding user, terminating the sale of the item at a closing price when the current sales volume has reached a threshold or when a period of time has passed since the sale was initialized, and crediting accounts belonging to one or more users with an additional amount based at least in part on a difference between the closing price and the purchase price for each item for the corresponding user.

The present disclosure provides systems and methods for displaying a real-world vehicle in an augmented reality environment. The system employs a user device camera to obtain image data of an environment that includes a real-world vehicle. The system analyzes the image data to identify the vehicle within the environment. A wireframe model of the vehicle is then generated and registered to the vehicle. The image data is displayed on the user device. In response to user input, the system may then attach a virtual vehicle accessory to the wireframe model. The accessory is then displayed on the user device display in an augmented reality environment such that the vehicle appears to seamlessly incorporate the accessory.

In an approach for generating and recommending optimized shopping orders for a group of users that collectively purchase bundles of goods, a processor generates an initial shopping order for each user in a group of shopping users, based on one or more preferences and constraints of each user on one or more items to buy from a stock. A processor optimizes the initial shopping order for each user based on one or more objectives of each user. A processor outputs the optimized shopping order for each user.

An apparatus includes a presenter. The presenter presents, as an option, a first product to be provided by a first provider to a user. The first provider is a provider accessed by the user. The presenter presents, as an option, a second product to be provided by a predetermined second provider to the user if it is not possible to provide the first product.

This document describes techniques, apparatuses, and systems for a blockchain-based transactive energy system. A blockchain-based transactive energy system receives a bid associated with a supply/demand curve of a utility from a transactive node through a smart contract. A universal identifier associated with the bid may be verified by consensus nodes of the blockchain-based transactive energy system to determine a verified set of bids. The universal identifier or other data associated with the bid may be stored in an immutable database provided by a blockchain. Based on the verified set of bids, a market-clearing price of the utility may be determined and used to satisfy the bid of the transactive node according to an actual production or consumption of the utility by the transactive node. The actual production or consumption of the utility may be stored in the immutable database for future audits or verification.

Systems, apparatus, and methods for providing a promotion to a consumer group are discussed herein. Some embodiments may include a system including circuitry configured for providing an impression associated with a promotion, receiving an indication to purchase the promotion associated with the impression as a consumer group, determining a group sale threshold, wherein the group sale threshold is a number of purchases of the promotion that must be met or exceeded by the consumer group before a group discount is awarded, providing the impression to each of the one or more additional consumers of the consumer group, via a consumer interface of each associated consumer device associated with each consumer account, determining one or more proposed group redemption times; and providing the one or more proposed group redemption times as a listing of selectable options.

A system of determining an alimentary preparation provider is disclosed. The system comprises a computing device. The computing device is configured to receive input from a user device at a current geographical location. The input comprises an alimentary request and a plurality of request parameters. The computing device generates a plurality of alimentary preparation providers as a function of the plurality of request parameters. A request parameter classifier is generated by the computing device. The computing device classifies, by the request parameter classifier, the plurality of request parameters and the plurality of alimentary preparation providers. The classification outputs an ordered list of request parameters. The computing device assigns the alimentary request to a first alimentary preparation provider as a function of an ordered list of request parameters. A method for determining an alimentary preparation provider is disclosed.
