A method of initiating a transaction in a blockchain system includes receiving, by a processing device, biometric data associated with a first party of a transaction to be added to a block of a blockchain system. The method further includes providing the biometric data to a validation node of the blockchain system. The method further includes determining that the biometric data has been validated by the validation node. The method further includes, in response to determining that the biometric data has been validated, recording, by the processing device, the biometric data in the block of the blockchain system.

Methods and systems for automatically conducting a continuous forward rate agreement in a cryptocurrency using smart contracts. An obligation object is generated and provided with control of a first smart contract, which may be a collateralized debt position smart contract, and control of a lender amount. The obligation object is executed to update balances for first and second parties until the obligation object is liquidated or terminated. Additional parties may be introduced. Upon liquidation or termination, the obligation object accounts to each of the parties based on their balances, and based on tokens generated to track positions in the obligation object.

The blockchain generation apparatus 1 includes: a parameter calculator 122 that identifies a parameter type to be used for linkage of the new block, based on block approval method data 114, and calculates a value for the identified parameter type based on transaction datasets which are related to an identifier of a generating party; a block generation condition checker 125 that determines whether the generating party is qualified to generate the new blockchain data, based on the value calculated by the parameter calculator 122; and a blockchain generator 126 that tries to generate the new blockchain by referring to the shared data when the block generation condition checker 125 determines that the generating party is qualified. An identifier of the blend pattern included in the block approval method data 114 specifies a combination of the plurality of parameter types that conflict with each other.

Embodiments of the present specification provide a method, an apparatus, a client terminal, and a server for data processing. The method includes: selecting, based on a data attribute of to-be-processed data, a target coordinating server from a plurality of coordinating servers, the plurality of coordinating servers belonging to a plurality of server clusters respectively; and sending a data processing request to the target coordinating server, such that a server cluster to which the target coordinating server belongs processes the data processing request preferentially, the data processing request directing to the to-be-processed data.

This invention relates generally to distributed ledger technology (including blockchain related technologies), particularly a method and corresponding system for providing a blockchain transaction comprising a redeem script for an output that comprises: i) a plurality of public keys, each associated with a corresponding private key, wherein each public key is uniquely associated with a potential state of at least one data source; and ii) logic arranged to provide a result based on: A) a determination of which of the plurality of associated private key(s) is/are used to sign the unlocking script, so as to provide an interim result: and B) a comparison of a parameter supplied via the unlocking script against the interim result, and further attempting to spend the transaction output more than once, each attempt supplying a different parameter.

An ecosystem is configured to facilitate digital exchange of digital assets in a digital asset marketplace. The ecosystem includes one or more of a plurality of participant systems selected from a list of participant systems including asset user systems, asset holder systems, and asset mining systems. The ecosystem operates on a computer-executable asset wrapper that is associated with the digital asset and that is configured in the form of a multi-layered structure. The ecosystem also includes a codec that is associated with the asset wrapper and configured as a computer executable file. The codec is executed responsive to a request for an exchange on the marketplace that is associated with the digital asset. The ecosystem further includes a blockchain device to execute a blockchain smart contract for the asset exchange. The blockchain smart contract is executed against a set of right tokens characterizing a specific cryptocurrency value.

The present invention is a novel system and method for coding, programming and administering a cryptocurrency platform.

A first security element is for transmitting an electronic coin data set to a second security element. The electronic coin data set is registered in a coin register of a payment system. The method has the steps of: setting a status of the electronic coin data set from the security element to an inactive status; transmitting the electronic coin data set from the first security element to the second security element; checking whether a receipt confirmation from the second security element has been received in the first security element; and deleting the transmitted electronic coin data set if the checking step results in that the receipt confirmation has been obtained by the first security element. The aforementioned relates to a payment system, a coin register, a security element, and a terminal for transmitting electronic coin data sets.

An apparatus for charging fees to a renter of equipment based upon wear to an item of equipment is disclosed herein. The apparatus can include a communications device proximal to the equipment that charges the renter, via a connected blockchain network, based off of the amount of vibration, pressure, flow rate, or temperature that the item of equipment is subjected to.

Techniques are described herein to allow for the utilization of digital currencies in a resource efficient manner, through a physical action blockchain. The physical action blockchain allows for mining/minting of digital currency based on transactions and/or physical actions performed in the real world.
