Abstract: A method of executing transactions of a blockchain network. A first transaction comprises at least a first output comprising a first locking script of a stack-based scripting language, the first locking script comprising a portion of the first locking script to be executed before a first instance of an opcode is executed. A second transaction comprises a first unlocking script that references the first output in the first transaction. Upon executing the first instance of the opcode, execution of the first locking script is terminated whilst not invalidating the first transaction. A first data element is read from at least one stack, wherein the first data element is generated during execution of the first unlocking script and the portion of the first locking script. The first data element as read from the at least one stack is supplied to an off-chain function, wherein the function is configured to generate a result based on at least said first data element.

Abstract: Methods and devices to enable the splitting of storage and validation functions from mining function in a blockchain network. The storage and validation nodes create candidate blocks and collect block rewards from successfully mined blocks. The mining nodes provide hash power for mining the candidate blocks and received resources from the storage and validation node for successful mining of a candidate block. Atomic exchange mechanisms are described for preventing loss and fraud and minimizing the use of bandwidth by mining nodes.

Abstract: A method of executing a transaction of a blockchain. The transaction comprises at least one output comprising a locking script, and the locking script comprises an instance of a first opcode and one or more instances of a second opcode. Each instance of the second opcode separates portions of the locking script. Upon calling the instance of the first opcode, a first data element is read from at least one stack, the first data element being generated during execution of the locking script with an unlocking script of a different transaction. A first part of the locking script that follows an instance of the second opcode corresponding to the first data element is output.

Abstract: A method of recording a target transaction in a blockchain, comprising: obtaining an updated version of the target transaction, being updated relative to a pre-existing first version; and instead of the first version, sending the updated version to be propagated through a network of nodes to be recorded in the blockchain. The target transaction comprises an input comprising an unlocking script and a pointer to an output of a first transaction, the output of the first transaction comprising a locking script specifying a plurality of alternative conditions for unlocking that output. The unlocking script of the first version of the target transaction is configured to unlock the first output of the first transaction based on a first of said alternative conditions, and the unlocking script of the updated version is configured to unlock it based on a second one of said alternative conditions.

Abstract: A method comprising: providing a first transaction specifying an output amount of a digital asset to greater than pointed to by its inputs, wherein an output of the first transaction comprises a locking script specifying a condition; over a side channel, receiving an input from each of multiple users, and adding each received input to the first transaction; and once a target is reached, whereby the total input amount pointed to by the inputs of the first transaction is equal to or exceeds the output amount, causing the first transaction and a second transaction to be published to a blockchain network to be recorded in a blockchain. The second transaction comprises an input pointing to the output of the first transaction and comprising an unlocking script meeting said condition. The condition requires the unlocking script to include a media key enabling the users to access the item of media content.

Abstract: A method of managing an overlay network overlaid on data-storage transactions of a blockchain, whereby data content of the overlay network is stored in payloads of the data-storage transactions and overlay-layer links are defined between the data-storage transactions. The method comprises identifying a graph structure of the overlay network, wherein nodes corresponds to different ones of the data-storage transactions and edges correspond to the links. Each node is associated with a respective first key for signing an input of a child data-storage transaction to authorise writing the child to the blockchain. The method further comprises using a child key derivation, CKD, function to determine a hierarchical set of second keys having the same graph structure as the overlay network, wherein the second keys enable an additional function other than signing inputs of the data-storage transactions.

Abstract: A method of recording a target transaction in a blockchain, comprising: obtaining an updated version of the target transaction, being updated relative to a pre-existing first version; and instead of the first version, sending the updated version to be propagated through a network of nodes to be recorded in the blockchain. The target transaction comprises an input comprising an unlocking script and a pointer to an output of a first transaction, the output of the first transaction comprising a locking script specifying a plurality of alternative conditions for unlocking that output.

Abstract: A method of validating transactions for recordal in a blockchain comprises receiving one or more transactions at a node of a blockchain network. For each received transaction a protocol for validating the transaction is applied. The protocol is configured to allow a termination opcode to be included in an output script of the transaction. The termination opcode is configured to, upon being executed by the node, a) terminate execution of the output script, and b) not to invalidate the transaction based only on the inclusion of the termination opcode in the output script. The protocol is also configured to disallow any instance of the termination opcode from being included in an input script of the transaction, said disallowing comprising the node at least invalidating the transaction if any instance of the termination opcode is included in the input script.

Abstract: A computer-implemented method of generating a secondary transaction identifier of a target transaction which enables a querying user to determine whether the target transaction comprises a candidate data field. The method comprises identifying a set of data fields of the target transaction, each data field comprising respective data of the transaction; and generating a transaction hash tree. Each data field is hashed to generate a respective one of a plurality of leaf hashes of the transaction hash tree. The root hash of the transaction hash tree comprises the secondary transaction identifier.
