A system and method for tracking and validating value of a vehicle, includes a memory device, a wireless communication device, authentication processor that authenticates the vehicle and generates one or more security keys, and a processor maintaining a token linked to the vehicle that designates the vehicle as a stake. The processor executes instructions to when a condition change event of the vehicle occurs, receive information of a change of state from the vehicle, generate a message including the change of state information, sign the message with a private key, transmit the signed message using the wireless communication device, choosing a node of a blockchain distributed network, evaluating, via the chosen node, the signed message in accordance with distributed contract rules to determine an updated token value and a residual token, and receive and maintain the updated token value and the residual token.

Systems and methods for expediting math-based currency (MBC) transactions. One method includes receiving a request for a pending MBC transaction, the request include an MBC address of a first party, an MBC address of a second party, and an amount of MBC to be transferred and determining a balance of MBC associated with the MBC address of the first party based on accessing a listing of address balances. Further the method includes in response to determining a threshold likelihood of success of confirming the pending MBC transaction, generating and formatting a guarantee identifier and embedding a copy of the guarantee identifier in a field of the pending MBC transaction. Further the method includes transmitting the guarantee identifier and transferring the amount of MBC from the MBC address of the first party to the MBC address of the second party based on verifying the pending MBC transaction.

Disclosed herein are methods, devices, and apparatuses, including computer programs stored on computer-readable media, for protecting sensitive data of a transaction activity based on a smart contract in a blockchain. One of the methods includes: receiving activity data for creating an account for the transaction activity from a user, the activity data including at least an identifier of the smart contract in the blockchain and an expiration time of the transaction activity; sending the activity data to an authentication server for requesting a digital certificate of the activity data, wherein the digital certificate stores the identifier of the smart contract, and an expiration time of the digital certificate is set to be the expiration time of the transaction activity; and causing the account for the transaction activity to be created after to receiving the digital certificate from the authentication server.

The purpose of the present invention is to enhance user convenience by combining stored value type and server management type payment systems. A portable terminal 5 stores a terminal-side value balance in the portable terminal, and an electronic money server 2 stores a server-side value balance related to the terminal-side value balance. At the time of payment, the portable terminal 5 connects to the electronic money server 2 via a payment terminal 6 or the Internet 3. Then, if payment can be made by using the server-side value balance, the electronic money server 2 makes payment by using the server-side value balance; if the server-side value balance is not enough and there is a shortfall, the electronic money server 2 adds an amount corresponding to the shortfall by subtracting the amount from the terminal-side value balance.

A method for propagating survival of cryptographic currency after inactivity over a predetermined period of time in a blockchain through the use of smart contracts includes: receiving a propagation request that includes unspent transaction output addresses, a digital signature, and a recipient address; generating a smart contract that is configured to self-execute after a predetermined period of time to initiate transfer of cryptographic currency from the output addresses to the recipient address; submitting the smart contract to a node in a blockchain network for addition to the blockchain; monitoring for new blockchain transactions involving any of the unspent transaction output addresses; generating a new smart contract to update the unspent transaction output addresses based on new blockchain transactions; and submitting the new smart contract to a node in a blockchain network after updating.

Invention relates to systems and methods for creation, issuance and continuous recalculation of multiple purpose algorithmically regulated electronically encrypted means; electronic instruments and techniques of bilateral and multilateral exchanges-resultant-obligations settlement governed by at all times accessible and transparent and unambiguously defined digital protocols. The system further comprises four main elements of the system: a central EnAEMs (multiple purpose algorithmically regulated electronically encrypted means) issuance device, group control units connected to the, user devices connected to the EnAEMs issuance device and to one of the group control units, and accrual generating asset pool connected to the EnAEMs issuance device.

Methods, systems, and apparatus, including computer program products, in which a method includes attributing a value to a pre-paid payment instrument, determining an expiration time associated with the pre-paid payment instrument, and automatically return an un-used portion of value associated with the pre-paid payment instrument at the expiration time to the purchaser.

This invention relates generally to a system and method for managing and packaging resources, regularly distributing granular resources to individuals among groups of people, allowing individuals to receive said granular resources upon request in each timeframe. Enable said granular resources to synchronize with time, expire at the end of each timeframe. Enable said system to automatically refresh itself, start a new timeframe immediately after the previous timeframe ends, continuously and repeatedly distribute said resources to said groups of people in each timeframe.

A system and method for achieving financial transactions utilizing blockchain transfers wherein a microprocessor is coupled to at least one network adapter and is operable to access memory and execute computer-readable instructions to receive a transfer of a cryptocurrency amount into a first account; define a value to that cryptocurrency at that time and peg that value to the cryptocurrency until a subsequent financial transaction wherein at least a portion of the cryptocurrency is used to satisfy a transaction amount based upon a pegged value rather than a then current value. A hedging mechanism can be implemented to mitigate volatility of the incoming currency, such as a cryptocurrency.

Systems and methods are provided for generating and managing dynamic customized electronic tokens for electronic device interactions. A system for transferring data between a user device associated with a user and a remote device may include a memory storing instructions and a processor configured to execute the stored instructions. The stored instructions may configure the processor to receive, via a network, transaction information from the remote device, access information associated with an electronic token, and provide the electronic token to the remote device. The electronic token may be associated with at least one of the user or the user device, and a token server may generate the electronic token based on the received transaction information, and determine one or more expiration parameters for the electronic token.
