  • Patent number: 12346902
    Abstract: The invention relates to distributed ledge technologies such as consensus-based blockchains. Computer-implemented methods for a secure random number generation within blockchain scripts are described. The invention is implemented using a blockchain network, which may be, for example, a Bitcoin blockchain. A first transaction that includes a puzzle is validated at a node in a blockchain network, with the first transaction being associated with a digital asset, and with a solution to the puzzle being indeterminable at a time of validation of the first transaction. A pseudorandom number, based at least in part on a solution to the puzzle that is included in a second transaction, is generated at least in part by validating the second transaction, the second transaction created to transfer control of the digital asset associated with the first transaction. Control of the digital asset is transferred based at least in part on the pseudorandom number.

  • Publication number: 20250141693
    Abstract: 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 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.

  • Publication number: 20250104062
    Abstract: Techniques are provided for causing an injection of a serialized previous transaction into a locking script. A first script, of a first transaction to be validated, causes a 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 script, included in a second transaction, causes the node to at least obtain the first set of field values and the second set of field values of the particular transaction supplied as a result of execution of the first script, extract a transaction identifier from the first set of field values, and determine, based at least in part on the second set of field values, that the particular transaction corresponds to the transaction identifier. The first transaction is validated by executing the first script and the second script.

  • Publication number: 20240386426
    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.
