IMPLEMENTING LOGIC GATE FUNCTIONALITY USING A BLOCKCHAIN
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 OR, AND, XOR, NOT and so on. In some examples, the instructions may be provided in a hashed form. 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 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 processes.

SYSTEM AND METHOD FOR CONTROLLING ASSET-RELATED ACTIONS VIA A BLOCKCHAIN
According to one perspective, the invention provides a technical arrangement to calculate, register and/or apportion costs and/or generate income in proportion to the current ownership of an asset. One or more embodiments also comprise a novel technique for generating cryptographic sub-keys. Thus, one benefit provided by the invention is that it allows the secure distribution of costs and income for an asset registered and maintained on the Blockchain. In turn, this increases the capability of such assets to meet the real-world needs of various entities such as the asset itself and investing parties. In one embodiment the invention provides a computer-implemented system for controlling a transfer made via a blockchain in respect of an asset, the system comprising an asset having a plurality of private cryptographic keys, each private key being associated with an owner of the asset; a registry comprising a plurality of public cryptographic keys wherein each public key corresponds to a private key in the asset's plurality of private keys, and is associated with a redeem script hash that can be identified within an unspent blockchain transaction; a smart contract comprising at least one rule relating to the automated generation of one or more blockchain transactions to enable a transfer to be made in respect of the asset; and a computing agent arranged to evaluate and/or execute the at least one rule of the smart contract. In some embodiments, a hierarchy of computing agents is managed by a master agent to carry out the asset related tasks defined in the smart contract. The master and subordinate agents communicate to execute discrete tasks.
The invention relates to the fields of tokenisation, blockchain and smart contract technologies. It provides a technical arrangement which simplifies the automated management of contracts. The invention comprises a method and system which use a computer-based repository for storage of the contract. The contract is then represented by a transaction on the blockchain. Metadata within the transaction's script includes a hash of the contract and a means of identifying its location within the repository. The transaction also includes an unspent output (UTXO) which indicates its status as an open (ie not terminated) contract. The contract is terminated by spending the output at a later point in time, for example, using nLockTime + CheckLockTimeVerify (CLTV). By combining this concept with other techniques and computing components, the invention can provide a powerful mechanism for implementing various tasks such as renewing or rolling over the contract, or dividing it into sub-contracts or conditions. Furthermore, as the status and existence of the contract is evidence via the blockchain, this provides a permanent, publicly visible and non-alterable record of the contract.

AGENT-BASED TURING COMPLETE TRANSACTIONS INTEGRATING FEEDBACK WITHIN A BLOCKCHAIN SYSTEM
This invention relates generally to blockchain implementations and is suited for, but not limited to, use with the Bitcoin blockchain. It can be used for the implementation of automated processes such as device/system control, process control, distributed computing and storage and others. The invention provides a solution which uses a blockchain to control a process executing on a computing resource. In a preferred embodiment, the computing resource, running simultaneously and in parallel to the blockchain, manages a loop-based operation. The computing resource continuously monitors the state of the blockchain as well as any other off-blockchain input data or source. The execution of the loop is influenced by the state of the blockchain. Each iteration of the loop that is executed by the computing resource is recorded in a transaction that is written to the blockchain. It is stored as a hash within the transaction's metadata. If the computing resource finds a transaction which contains a hash relating to the loop it accesses the relevant portion of code. The loop contains a conditional statement which enables the computing resource to decide which action to take. The condition may be dependent upon the state of the blockchain or any other data source. The action can be any type of action, on or off the blockchain. Thus, the combination of the computing resource and blockchain provide a solution which is (at least partially) Turing-complete.
