If blockchains acquired data from external sources (i.e. from the true earth), determinism would be not possible to attain, avoiding nodes from agreeing within the validity of alterations into the blockchain’s point out. Consider as an example a wise contract that executes a transaction depending on the current ETH-USD exchange price acquired from a traditional selling price API.
