A method, a computer device, and a non-transitory computer-readable recording medium for preventing an erroneous deposit of cryptocurrency are provided. A method of preventing an erroneous deposit of cryptocurrency includes providing an interface for inputting transaction request information including a target coin and a wallet address; verifying at least one of the target coin and the wallet address using a trading environment of a target exchange corresponding to the transaction request information; and processing a transaction according to the transaction request information based on a verification result.

A system, method, and apparatus for decentralized e-commerce and related transactions are provided. A computing system is configured to generate buyer and seller digital wallets on a distributed ledger, receive listings for products sales from a seller electronic device, display listings for sale, and receive requests to purchase any of the listings from a buyer electronic device. A computing system is configured to chain a new block of data to a previous block of related data each time an inquiry, transaction, or other interaction with data contained with a digital wallet, such as currency or product or service listings, are received. The computing system is further operative to authenticate, display, and even translate communications transmitted and received by and between buyer/seller user electronic devices.

The invention relates to a method for producing a cryptographically signed transaction for the transfer of an amount of a currency within a blockchain. The transaction comprises one or more inputs and one or more outputs. The method comprises: retrieving the one or more inputs, the inputs being a reference to one or more previous transactions, determining the one or more outputs, each output defining an amount to be transferred to a receiver indicated in the respective output, adding security information, the security information defining directly or indirectly a maximum amount to be spent with the transaction, and cryptographically signing the transaction by adding signature information.

An integration system for a system of platforms includes an orchestration platform, a blockchain transactional platform, a digital transactional platform, a merchant system, a user trust platform, and one or more user devices connected to each other and a distributed ledger and/or a secondary mesh network via one or more networks. The blockchain transactional platform performs accesses and performs actions on the distributed ledger and/or the secondary mesh network. The digital transactional platform maintains transactional data indicative of an amount of first-domain value correlated to a user. The blockchain transactional platform maintains blockchain transactional data indicative of an amount of second-domain value correlated to the user. The orchestration platform manages data exchange, synthesis, fusion, analysis, and transformation between the components of the system, including for the orchestration of transactions.

A network electronic device, method, and computer program product facilitate receiving, via a network interface and a network, transaction information originating from at least one of a merchant electronic system and a consumer electronic device associated with a hard currency transfer from a consumer to a merchant. In response to determining that the hard currency transfer is more than a full transaction amount, a controller of the network electronic device debits a merchant account balance in the digital currency accounting system associated with the merchant to correspond to an excess amount of the hard currency transfer. The controller credits a consumer account balance in the digital currency accounting system associated with the consumer to correspond to the excess amount of the hard currency transfer. The controller communicates an updated balance to at least one of the merchant electronic system and the consumer electronic device to conclude an associated transaction.

A digital platform enables 3D printing where the designs are protected from piracy/redistribution. A single board computer (SBC) communicates with a first server and a second server. The SBC requests a unique hardware ID from the first server, which assigns and sends the ID to the SBC. The SBC submits the ID and a secret key to the second server to request registration of a user and a printer, and the second server sends private certs, a client ID, and a unique public identifier to the SBC. The second server also receives and stores 3D print designs through a designer portal, and on-demand displays the designs in a GUI screen. The SBC user may purchase a 3D print design, and the second server, in response, sends an access token to the SBC. The SBC redeems the access token for a selected 3D print, and the second server adjusts geode for the selected 3D design for the particular printer, and streams the adjusted geode to the printer through the SBC, thereby protecting the code from unauthorized user/replication.

The present application discloses an information processing method. The method includes: acquiring a resource package parameter determined by a sender client; invoking an interface with a second server, and acquiring a current conversion rate that is between the first-type resource and a second-type resource and is issued by the second server; calculating a quantity of second-type resources equal in value to the first quantity of first-type resources according to the conversion rate, and using the quantity as a second quantity; deducting the second quantity of second-type resources from a second-type resource account of the sender client, and generating at least one resource package, a sum of quantities corresponding to the at least one resource package being equal to the first quantity; and distributing the at least one resource package to at least one receiver client by using the link information.

The present invention relates to a two level crux chain platform with a Proof of History (PoH) for increasing security, robustness and/or verifiability of a blockchain includes a first initial block with a node assigned to an address of a shard, a plurality of following blocks comprising a new address for each of the following blocks generated using previous address and previous block head by a ladder swapping protocol, a record stream with a plurality of stream value and each stream value is a current record value hashed with a previous stream value and a blockchain server for storing a plurality of modules.

The present technology relates to information processing system and method, and information processing device and method for realizing a system capable of increasing efficiency while reducing load concentration. Each of the information processing system and method and the information processing device and method according to an aspect of the present technology belongs to one or more center servers. One or more gate controllers different from each other are allocated. Acquired is user data that relates to data about a user corresponding to identification data, and is supplied on the basis of prediction data corresponding to the identification data. Acquired is the identification data that is read from a storage device storing the identification data, and is supplied from the gate controller allocated to the corresponding system, method or device. The acquired user data that corresponds to the acquired identification data is processed. For example, the present technology is applicable to an information processing device or an information processing system.

In one embodiment, a method includes receiving a request for payment associated with a transaction between a first user and a second user, where the request specifies a payment amount in a fiat currency and identifying an indication that the first user intends to satisfy the request for payment using a non-fiat instrument. The method also includes initiating a first transfer of a value corresponding to the payment amount in the non-fiat instrument from a first balance of the first user to one or more service balances of a payment service and initiating a second transfer of a value corresponding to the payment amount in the fiat currency from the one or more service balances of the payment service to a second balance of the second user.
