Abstract

Claims (25)

1. A computer-implemented control method comprising the steps of:

providing a locking script in a first blockchain transaction, the locking script comprising at least one first instruction arranged to

implement functionality of a logic gate and at least one second instruction arranged to process at least one input signal to obtain at least one Boolean input;

providing a further blockchain transaction having an unlocking script configured to present the at least one input signal to the locking script of the first blockchain transaction;

presenting the at least one input signal to the locking script of the first blockchain transaction by executing the unlocking script of the further blockchain transaction;

processing the at least one input signal to obtain at least one Boolean input by executing the at least one second instruction in the locking script of the first blockchain transaction;

implementing the functionality of the logic gate by using the at least one Boolean input to execute the at least one first instruction in the locking scripts of the first blockchain transaction;

transmitting the further blockchain transaction to a blockchain network for validation; and

providing a computing resource arranged to influence a behavior of an off-block process based upon:

detection of the further blockchain transaction within a blockchain or blockchain network; and/or

the validity of the further blockchain transaction.

2. A method according to claim 1 wherein the logic gate is one or more of an OR gate, XOR gate, NAND gate, NOR gate, a NOT gate, an XNOR gate, an IMPLY gate, or a Converse implication gate.

3. A method according to claim 1 wherein the step of processing the at least one input signal to provide the at least one Boolean input is performed by at least one computing resource or agent prior to providing them to the locking script.

4. A method according to claim 1 and comprising the step of:

monitoring or searching the blockchain or blockchain network to determine a presence or absence of the further blockchain transaction.

5. A method according to claim 1 and comprising the steps of:

interpreting the detecting of the further blockchain transaction within the blockchain or blockchain network as a TRUE output of a logic gate.

6. A method according to claim 1 wherein validation of the further blockchain transaction within a blockchain network is dependent upon the execution of the unlocking script.

7. A method according to claim 1 and comprising the step of:

controlling a device or process based upon the validity of the further blockchain transaction, wherein the validity is determined or established by a computer-based control agent, or by monitoring the blockchain network to determine if it has been validated by a network node, and/or by monitoring a state of the blockchain to determine whether the further transaction has been written to the blockchain.

8. A method according to claim 1 wherein the at least one input signal comprises one or more of a numeric value, a constant value, a result of a hash function, a cryptographic key, a blockchain puzzle, or a Bitcoin other blockchain-related address.

9. A method according to claim 1 wherein the first and/or further blockchain transaction is generated and/or transmitted to a blockchain network by an automated process executing on a computing-based resource.

10. A method according to claim 1 wherein the at least one instruction:

comprises a Boolean condition or operator; and/or is written and/or executed using a stack-based programming language.

11. A computer implemented system arranged to implement a method of claim 1 .
