Abstract

The invention relates to distributed ledger technologies such as consensus-based blockchains. Computer-implemented methods for locking and unlocking blockchain transactions are described. The invention is implemented using a blockchain network. A first unlocking script of the unlocking blockchain transaction is configured to unlock a first locking script, wherein the first locking script is configured, when executed together with the first unlocking script, to determine, based on the first locking script and a constraint for verifying the unlocking blockchain transaction. Verifying the unlocking blockchain transaction is based on a set of constraints and corresponding field of the unlocking blockchain transaction, wherein data is based on the set of constraints. Providing data at the corresponding field of the unlocking blockchain transaction. Finally, making the unlocking blockchain transaction available to one or more nodes of a blockchain network.
