USING AN INTERNAL LEDGER WITH BLOCKCHAIN TRANSACTIONS

Resumen de: US2025348864A1

Systems, methods, and computer-readable media disclosed herein relate to reducing computation and computing resources for certain blockchain related transactions. Specifically, software algorithms and architecture allow some transactions to avoid the need for recordation on a blockchain, which can be computationally expensive both for a requesting device and for various nodes on the blockchain. Thus, a computer system may receive indications of incoming transactions transferring digital assets to particular user accounts, and in response to requests from user accounts, the computer system facilitates one or more internal transactions between those accounts. In response to a request from a particular internal user account, the computer system may perform an outgoing transaction transferring one or more digital assets to an external user account from one or more internal user accounts. The incoming transactions and outgoing transaction are recorded on the blockchain, but the internal transactions are recorded on an internal ledger rather than the blockchain, saving computational power and improving computer operations.

METHODS AND SYSTEMS FOR FREEZING DIGITAL ASSETS

Resumen de: US2025350477A1

Systems and computer-implemented methods for freezing or unfreezing digital assets on a blockchain. A freeze administration service may send a signed freeze request to mining nodes, which maintain two blacklists of digital asset identifiers: a pending blacklist and a consensus blacklist. The digital asset identifiers may be transaction outpoints in some cases. If accepted by the mining node, the transaction outpoints in the freeze request are added to the pending blacklist, which causes rejection of any transactions using those outpoints, but does not cause rejection of any new blocks that include transactions using those outpoints. If a consensus threshold of acceptances is reached based on hash power, the request becomes an order and the outpoints are added to the consensus blacklist, which causes rejection of any transaction or block containing a transaction using those outpoints.

A computer-implemented method comprises creating, at a node in a blockchain network, a first transaction, wherein the first transaction includes a first output having a first spendable value and a first locking script and a second output having a second spendable value and a second locking script. A first set of constraints on a first selected transaction output is included in the first locking script, wherein the first set of constraints are to be met by a first unlocking script if the first selected transaction output is to be valid for spending the first spendable value. A second set of constraints on a second selected transaction output is included in the second locking script, wherein the second set of constraints are to be met by a second unlocking script if the second selected transaction output is to be valid for spending the second spendable value. The first set of constraints or the second set of constraints imposes a constraint on a locking script of a spending transaction having as a spending transaction output the first selected transaction output or the second selected transaction output.
