Digital contracts using blockchain transactions

Номер: GB0002592338A

Methods relating to implementing digital contracts, such as smart contracts, between two parties 103 over a blockchain network 106 involve storing conditions for fulfilling the contract in a hash tree, such as a Merkle tree (fig 9). In one embodiment, the hash tree is generated by a trusted third party 701 by hashing data elements representing the conditions for use as a first set of leaf hashes of the tree, and hashing at least one secret value known only to the third party for use as a second set of leaf hashes of the tree. The root hash (Merkle root) is inserted into a first blockchain transaction published by the first party 103a. When contractual condition(s) are fulfilled, the third party 701 provides the authentication path (Merkle path) and hash(es) of the secret(s) to the second party 103b, which are included in a second transaction which unlocks the first. In a second embodiment (fig 8), the two parties generate a hash tree encoding the conditions, and when a condition is fulfilled ...

A method to control devices 502 with bridging nodes 503 in an overlay network 501, each bridging node also being a node of a blockchain network 106. A blockchain transaction is generated by a first bridging node 503a or 503b. The transaction consists of an input comprising a signature linked to a public key of the first node and an output comprising an identifier of a first device 502a that is controlled by a second bridging node 503c, and a command message for controlling the device. The second node obtains the blockchain transaction and transmits a command to the device which is based on the command message of the transaction. The transaction may be updated by the second node such that it may be observed from the blockchain which node issued the command and which actioned the command. A command-request transaction may also be used whereby the first node requests approval prior to generating the transaction to be actioned. Approval is given by the request transaction being signed by two ...

Methods and Devices for Tracking and Measuring Proof-of-Work Contributions in a Mining Pool

Номер: GB0002586865A

Blockchain proof-of-work contributions made by miners within a mining pool are tracked by a pool master storing a Bloom filter. The Bloom filter stores candidate block header information submitted by miners during their proof-of-work searching. If a submitted block header is not stored in the Bloom filter, the Bloom filter is updated to store the block header. If a submitted block header likely exists in the Bloom filter, a count of invalid blocks associated with that miner may be increased. Block headers may be hashed and the result compared to a threshold difficulty value higher than the blockchain’s proof-of-work difficulty parameter. If the time of receipt between two block headers from the same miner deviates from a target, then the threshold difficulty value for that miner may be adjusted. In this way, submitted block headers may constitute regular partial proof-of-work reports by each miner. If the pool mines a valid block, a share of the reward may be allocated based on each miner ...

Method for granting permission to a requester to join a first network 501. The first network comprises a set of bridging nodes 503 and a set of devices 502 controllable by one or more of the set of bridging nodes (gateway nodes). Each bridging node is also a respective node of a blockchain network 106. A requester 502 or 503 sends a request to a registration authority (one of the bridging nodes) to join the network and obtains, if the credentials supplied with the request are valid, a first certificate therefrom comprising an identifier assigned to the requestor. The registration authority generates a first blockchain transaction (“certification transaction”). The first blockchain transaction comprises an input comprising a signature, linked to a first public key of the registration authority. The first blockchain transaction also comprises a first output comprising the first certificate, which comprises the identifier assigned to the requestor. The method further comprises transmitting ...
