Abstract

See full text

The invention relates to distributed ledge technologies such as consensus-based blockchains. Computer-implemented methods for securely providing undetermined data from a determined or undetermined source are described. The invention is implemented using a blockchain network, which may be, for example, a Bitcoin blockchain. A first transaction to validate is received at a node in a blockchain network, with the first transaction including a first script that includes at least a first value, at least a portion of which includes data that is unconstrained by a second script, and a second value. A second transaction is obtained. The second transaction having been validated and including the second script that, as a result of being executed, causes the node to obtain the first value and the second value as a result of execution of the first script, and validate, based at least in part on first value and the second value, that the data is associated with a data source. The first transaction is validated by executing the first script and the second script.
