A method is provided for enabling the execution of one or more smart contracts based on a Hypertext Transfer Protocol (HTTP) transmission protocol format request from the client, accessing a smart contract SC in the request and identifying an event stream ES implemented using the blockchain, where the ES is specific to the SC, the ES representing the states of the SC. The current state of the smart contract ESis determined and execution of the smart contract SC is invoked. The method invokes updating the ES by processing a new event Efor the ES, is identified in the received request, and processed by creating a blockchain transaction. The current state of the smart contract on the blockchain is then updated to be ES=ES, based on the new event E. A result associated with updated current state ESis then provided.

Compute services for a platform of services associated with a blockchain

Methods and systems for registering identity of a mining node on a blockchain in a blockchain network. The methods may include creating a validity-check transaction having a first output controlled by the mining node and containing a miner identifier and propagating the validity-check transaction on the blockchain network. The methods may further include mining, by the mining node, a new block containing a generation transaction, wherein the generation transaction includes an information field that contains the miner identifier and a reference to the validity-check transaction. Another node may validate identity by receiving the miner identifier and the reference to the validity-check transaction, retrieving the validity-check transaction to confirm it contains the miner identifier, and determining that the first output is an unspent transaction output.

Methods and devices for registering and authenticating miner identity in a blockchain network

A platform provides a plurality of services that are associated with a blockchain. A platform processor is capable of receiving an HTTP client request for a service. Further to verification of the identity of the client and/or the request, a destination address or endpoint for the requested blockchain service is determined, and at least one blockchain transaction is generated based on the destination address to obtain an output script. A result based on the output script is then sent to the given client in the HTTP transmission protocol format. The blockchain transaction can be associated with an event stream that is implemented as a Finite State Machine on the blockchain. The blockchain transaction can be generated to create, amend or terminate an event stream that is implemented using the blockchain, the transaction spending a dust output of a previous transaction and/or having an unspent dust output.

Event streams for a sequence of events associated with a blockchain

In a first aspect, the present disclosure proposes methods, devices and systems for implementing a platform providing a plurality of services that are associated with a blockchain, using a platform processor associated with an application programming interface (API) that is capable of receiving a client request in a Hypertext Transfer Protocol (HTTP) transmission protocol format for a service. Further to suitable verification of the identity of the client and/or the request, a destination address or endpoint for the requested blockchain service is determined, and at least one blockchain transaction is generated based on the destination address to obtain an output script. A result based on the output script is then sent to the given client in the HTTP transmission protocol format. In some aspects, the blockchain transaction is associated with an event stream that is implemented as a Finite State Machine on the blockchain.

Platform for a plurality of services associated with a blockchain

In a first aspect, the present disclosure proposes computer implemented methods, devices, and systems for implementing a channel service for messages or transactions that are associated with a blockchain, the channel service being provided for one or more clients. The method comprising providing a given client access to one or more functions that enable direct communication between the given client and another entity, the one or more functions include (i) channel functions or procedures pertaining to one or more channels for transmission of data; and/or (ii) message functions or procedures pertaining to the data being transmitted using the one or more channels. In a second aspect, the present disclosure proposes computer implemented methods, devices, and systems for implementing addressing for a channel service, such as the channel service in the first aspect. Communication using a channel associated with the channel service is initiated based on the addressing keys pertaining to the communicating entities.

Computer-implemented system and method

A computer-implemented method of generating a transaction for a blockchain, the transaction being for transferring an amount of a digital asset from a first party to a second party. The method comprises generating a first transaction comprising an output locking the amount of the digital asset, the output comprising an output script comprising a plurality of criterion components each requiring a respective input data item, and a plurality of counter script components. Each criterion component is associated with one of the counter script components. The output script is configured so as to, when executed alongside an input script of a second transaction, i) increment a counter each time a respective criterion component is satisfied by a respective input data item of the input script, and ii) to require the counter to increment to at least a predetermined number in order to be unlocked by the input script.

Multi-criteria blockchain protocol

Methods and system of recording work history of a mining node on a blockchain in a blockchain network. The methods may include mining a first block containing a registration generation transaction that includes, within a registration information field, a miner identifier for the mining node; and mining two or more additional blocks in an order, each additional block containing a generation transaction that includes an information field containing the miner identifier, a reference to the generation transaction of the preceding additional block in the order, wherein the registration generation transaction is a first block in the order. Work history may be verified by tracing the recorded work history and validating the miner identifier. Recorded work history may serve as the basis for a reputation score for the miner, which reflects contributed work evidenced by the proof-of-work secured work history.
