Abstract

The invention relates to distributed ledger technologies such as consensus-based blockchains. Computer-implemented methods for locking blockchain transactions are described. The invention is implemented using a blockchain network. A first locking script is configured in a blockchain network. The first locking script is executed together with a first unlocking script, based on data obtained by executing the first unlocking script and a set of constraints. Verification that a first set of field values of the unlocking blockchain transaction is obtained by executing the first unlocking script and the set of constraints against the unlocking blockchain transaction. Validating the unlocking blockchain transaction according to the set of constraints. Finally, making the locking blockchain transaction available to one or more nodes of the blockchain network.
