Abstract: The invention relates to distributed ledge technologies such as consensus-based blockchains. Computer-implemented methods for securely providing undetermined data from a determined or undetermined source are described. The invention is implemented using a blockchain network, which may be, for example, a Bitcoin blockchain. A first transaction to validate is received at a node in a blockchain network, with the first transaction including a first script that includes at least a first value, at least a portion of which includes data that is unconstrained by a second script, and a second value. A second transaction is obtained. The second transaction having been validated and including the second script that, as a result of being executed, causes the node to obtain the first value and the second value as a result of execution of the first script, and validate, based at least in part on first value and the second value, that the data is associated with a data source.

Abstract: The invention relates to distributed ledger technologies such as consensus-based blockchains. Computer-implemented methods for a trustless, deterministic state machine are described. The invention is implemented using a blockchain network, which may be, for example, a Bitcoin blockchain. A first transaction to validate is received at a node in a blockchain network. The first transaction includes a first script that, as a result of being executed, causes the node to at least obtain a first set of field values of the first transaction, a second set of field values of a second transaction, and an input. The second transaction is obtained.

Abstract: The invention relates to distributed ledge technologies such as consensus-based blockchains. Methods for causing an injection of a serialized previous transaction into a locking script are described. The invention is implemented using a blockchain network, which may be, for example, a Bitcoin blockchain. A first transaction to validate is received at a node in a blockchain network, with the first transaction including a first script. The first script, as a result of being executed, causes the node to at least obtain a first set of field values corresponding to the first transaction and obtain a second set of field values corresponding to a particular transaction. A second transaction is obtained, with the second transaction having been validated and including a second script.
