The disclosure is related to injection of a serialized set of field values of an unlocking transaction into a locking script, such as for distributed ledge technologies and consensus-based blockchains. A first transaction to validate is received at a node in the blockchain network. The first transaction includes a first script that includes a set of field values of the first transaction and, as a result of being executed, causes the node to obtain a set of field values. A second transaction is obtained, with the second transaction having been validated. The second transaction includes a second script that, as a result of being executed, causes the node to generate a signature based at least in part on the set of field values supplied as a result of execution of the first script. The first transaction is validated by execution of the first script and the second script.
