Abstract
The invention relates to distributed ledger technologies such as consensus-based blockchains, for example, a Bitcoin blockchain. Computer-implemented methods for a trustless, deterministic state machine that is embodied by the locking script of a spending transaction are described. The spending transaction transfers control of at least one digital asset or portion thereof. The spending transaction references a previous transaction that includes a locking script with a bytecode sequence. The spending transaction also includes a locking script with the same bytecode sequence. The spending transaction can be validated by verifying that the bytecode sequences of the locking scripts of the spending and previous transactions match one another. Control of the at least one digital asset or portion thereof can be transferred as a result of execution of the locking script. For example, the locking script can impose a set of conditions for validation of the spending transaction.
