SCRIPT-BASED BLOCKCHAIN INTERACTION

原文（中文）

There may be provided a computer-implemented method. It may be implemented using a blockchain network such as, for example, the Bitcoin network. The computer-implemented method includes: i) receiving, at a node in a blockchain network, a first transaction associated with a digital asset, the first transaction including a first script that specifies a set of constraints on a second transaction to transfer control of the digital asset, the set of constraints including a constraint that a set of data obtained by the node includes information obtained from a blockchain associated with the blockchain network; ii) obtaining the second transaction, the second transaction including a second script that, as a result of being executed, causes the node to obtain the set of data; and iii) validating the second transaction by executing the first script and the second script.
