A settlement device can acquire a payment amount and a balance of electronic money. When the balance is less than the payment amount, the settlement device gives a notification of a necessary charging amount set based on an amount of money obtained by subtracting the balance from the payment amount. The settlement device receives an input of money. When the necessary charging amount is notified and an input of money equal to or greater than the necessary charging amount is received, the settlement device settles a transaction by updating the balance to the amount of money obtained by subtracting the payment amount from the amount of money obtained by adding the input amount of money to the balance.

The present invention discloses a method by which a secure ledger network is deployed to provide assurance related to title of IP assets. Specifically, the invention seeks to improve the risk associated with IP based transactions and reduce the time related to researching color of title related to the same.

Systems and methods for selling virtual items on multiple online sales platforms simultaneously are disclosed. Exemplary implementations may: receive a sales request that indicates the selling user will be offering for sale a particular virtual item through at least two online sales platforms simultaneously; assign ownership of the particular virtual item temporarily to a holding account; generate sales listings of the particular virtual item for publications on the at least two online sales platforms; effectuate the publications of the sales listings; receive indications of offers to purchase the particular virtual item; determine an accepted offer that is accepted; notify the at least two online sales platforms of whether the offers have been accepted or denied; identify a buyer's account of the buying user; effectuate assignment of the ownership of the particular virtual item to the buyer's account.

Provided is a method for providing a reward based on consumption of content performed by a computing device. The method comprises querying a user terminal located in a first space by using location information of a first space, measuring the number of users located in the first space according to the number of the queried user terminals and a first content playback record and calculating a first reward for the first content by using the measured number of users and the first content playback record, and providing the first reward to an account of a producer linked to a producer terminal of the first content.

A method for facilitating foreign transactions through inter-currency exchanges and geographical matching includes providing a platform to consumers located in different countries, where a consumer in a first country that desires a product from a second country is matched to a consumer in the second country that desires a product in the first country; the consumers are matched and transactions initiated by the platform to provide transfer of any necessary payment to ensure that each consumer can make the purchase on behalf of the other consumer in their own country, for shipping to the consumer in the other country, negating the need for the consumers to make any international purchases directly while still availing themselves of foreign products without involving merchants and minimizing the effect and amount of cross-border transactions.

Methods, apparatus and techniques are disclosed to define and use bearer token records to transfer a crypto asset from a sending account and where a secret is required to be provided as a proof of possession of the bearer token to complete the transfer to a receiving account. Certified bearer tokens are locked for later transfer to a defined receiving account at generation. Lockable bearer tokens are lockable after generation via a second secret. Bearer token records may be expired to revert the crypto asset to the sending account if not completed using the secret. Bearer token records are implementable on a blockchain. Bearer tokens of small denomination crypto assets are useful for various transactions such a streaming or other online services. A computing device provides a change purse from which to pay using bearer tokens. Various user interfaces and uses are presented.

A system and method for blockchain-based document processing includes a processor, network interface, print engine, scan engine, and a memory storing a blockchain ledger. The blockchain ledger includes time stamped blocks, each block including currency data associated with a digital currency value. The processor generates a block corresponding to a received instruction, a preexisting currency value associated with the received instruction and contract data corresponding to a smart contract associated with the received instruction. The processor updates the blockchain ledger with a generated block and shares an updated blockchain ledger with other networked data devices via the network interface. The processor also receives verification of the updated blockchain ledger from the other networked data devices. The processor executes the smart contract upon receipt of verification.

Techniques for integrating a payment processing platform (PPP) and a payment making platform (PMP) for differentiated payment allocations using cryptocurrency is described. In response to an indication to allocate a first portion of funds generated from payment received for transaction(s) processed by the PPP to a cryptocurrency wallet account for a user, the PMP can receive a request for first account information associated with the cryptocurrency wallet account. The PMP can send the first account information to the PPP, wherein the first account information is associated with second account information of a merchant account of the user. The PMP can receive, from the PPP, a request to deposit a first portion of the funds into the cryptocurrency wallet account, wherein a second portion of funds is retained by the PPP for deposit into the merchant account as fiat currency.

An incorrect transmission, of a record of data to a distributed ledger system, can be prevented. A first signal can be received. The first signal can include a first instruction to cause the record to be transmitted to the system. One or more items of information in the record can be determined. A delay of time to be elapsed, before a transmission of the record to the system, can be set in response to a receipt of the first signal and a determination of the one or more items. The transmission of the record to the system can be caused to occur after the delay has elapsed. The transmission of the record to the system can be prevented in response to a receipt of a second signal before the delay has elapsed. The second signal can include a second instruction that supersedes the first instruction.

A custom cryptographic token and smart contract that is configured to exist in one of two groups and is issued by the same bank or depository institution that also collects corresponding fiat currency deposits. The two groups are a circulation group and a non-circulation group. The non-circulation group is not associated with any given user, but rather an issuing entity. Custom cryptographic tokens residing in the circulation group are associated with a user and are traded according to smart contract protocol.
