The invention presents a solution in which blockchain Transactions are created to implement the functionality of a logic gate. The invention may be implemented on the Bitcoin platform or an alternative blockchain platform. The transaction includes a locking script which comprises instructions selected so as to implement the functionality of a logic gate, such as the XOR gate. When the script is executed (because a second transaction is attempting to spend the output associated with the locking script) the inputs will be processed by the conditional instructions to provide an output of TRUE or FALSE. The inputs are pre-processed by one or more computing agents so that they are evaluated to TRUE or FASLE prior to being used as inputs to the script. The second transaction is transmitted to the blockchain network for validation and, if determined to be valid, it will be written to the blockchain. Validation of the second transaction can be interpreted as a TRUE output. Thus, the locking script of the first transaction provides the functionality of the desired logic gate. The invention provides numerous advantages and can be used in a wide variety of applications, such as for the implementation of control systems and unit.

Computer-implemented methods for locking a blockchain transaction based on undetermined data are described. The invention is implemented using a blockchain network. This may, for example, be the Bitcoin blockchain. A locking node may include a locking script in a blockchain transaction Node to lock a digital asset. The locking script includes a public key for a determined data source and instructions to cause a validating node executing the locking script to verify the source of data provided in an unlocking script by: a) generating a modified public key based on the public key for the determined data source and based on data defined in the unlocking script; and b) evaluating a cryptographic signature in the unlocking script based on the modified public key. The blockchain transaction containing the locking script is sent by the locking node to the blockchain network. The lock may be removed using a cryptographic signature generated from a private key modified based on the data.

The invention provides a method and corresponding system for controlling the generation of a blockchain transaction, and/or the recipient of a transaction output. It can also be used to control and record the ownership of an asset represented on the blockchain without the need for a separate registry of ownership. The ownership and transfers thereof can be handled and recorded without the need for knowledge of the parties involved or their identities. According to one embodiment, the method comprises the steps of identifying at least one transaction (Tx) on a blockchain which comprises: an unspent transaction output (UTXO) relating to a tokenised asset associated with an asset controller; and an input which spends an output from a previous transaction that is locked by a redeem script hash. For each identified transaction (Tx), an incomplete blockchain transaction is generated comprising: a first output comprising a copy of the redeem script hash; and a second output which is modifiable such that only the asset controller is able to specify a recipient for the second output. The incomplete blockchain transaction is communicated to the controller of the asset. The incomplete blockchain transaction is incomplete in that it is missing a required cryptographic signature. Thus, payment of income relating to the asset can be re-directed by the controller to a destination of their choice.

A computer-implemented method is provided comprising: generating a digital data block comprising transaction data representing at least one energy transfer transaction corresponding to an exchange of charge between a community member device and a charge source device, randomly selecting, in a group of community member devices, a plurality of block verification devices, wherein the block verification devices form a subgroup of block verification devices, partitioning a block verification computation task for the digital data block into a plurality of block verification computation subtasks, assigning the block verification computation so subtasks to respective selected block verification devices, transmitting the digital data block to each selected block verification device, together with its respective block verification computation subtask over a computer network, determining that the digital data block is verified, based on at least one verification results of a corresponding block verification computation subtask, and adding the verified block to a blockchain-enabled storage system.
