Using, processing and/or generating at least one blockchain transaction suitable for updating a blockchain token (e.g. transferring a blockchain token between entities). A transaction includes a latch mechanism for controlling the update. The latch mechanism can be described as imposing a conditional update of the token e.g. an interlock. The relationship with the previous and subsequent transactions is used to inhibit double spending or determine token validity using an inductive proof. The latch mechanism comprises: the unlatch-script, which is configured to release a preceding restriction, said preceding restriction applied in a preceding blockchain transaction and configured to restrict update of the blockchain token and/or the latch-script, which is configured to apply a subsequent restriction, said subsequent restriction configured to restrict the ability to assign the blockchain token in a subsequent blockchain transaction e.g. by the another entity.

The embodiment of the invention provides a database covering and indexing mechanism implemented by a block chain. In one embodiment, records in a database are associated with respective unconsumed outputs in one or more transactions on a blockchain by overlay. Each output includes a lock script that specifies which keys can be used to consume the output to other transactions. When a user wishes to access a given record in the database, the other (expending) transactions are generated and sent to a blockchain network. The other transactions include an unlock script that provides one or more keys required to meet the conditions of the lock script, otherwise a consensus mechanism of the blockchain will not allow expenditure of the output and access to the record will be denied. However, if a requirement is met, the output is consumed, and an access request is considered to be authorized. In this way, the consensus mechanism provides an improved authority control and user authorization scheme for a database. When the output is consumed by the other transactions, the overlay is updated to associate the record with the consumed transaction. Transaction logs can also be provided to quickly and efficiently regenerate the database when needed.

The invention relates to distributed ledge technologies such as consensus-based blockchains. The methods and systems of the present disclosure are provided for causing an injection of a serialized set of field values of an unlocking transaction into a locking script are described. The invention is implemented using a blockchain network, which may for example be a Bitcoin blockchain. A first transaction to validate is received at a node in the blockchain network. The first transaction includes a first script that includes a set of field values of the first transaction and, as a result of being executed, causes the node to obtain a set of field values. A second transaction is obtained, with the second transaction having been validated. The second transaction includes a second script that, as a result of being executed, causes the node to generate a signature based at least in part on the set of field values supplied as a result of execution of the first script. The first transaction is validated by execution of the first script and the second script.
