What are Blockchain Oracles? (animated explainer video)

What Is An Oracle?

An oracle is a data source that provides information to a blockchain system. The oracle acts as a bridge between the world outside the blockchain and the blockchain itself. The blockchain is an immutable ledger that keeps track of transactions and records them in blocks. Oracles provide external data that can be used to update the blockchain. The use of an oracle is a way of getting external data into a blockchain network. The data can be anything from the current weather conditions in a certain area to the last time a transaction was made. Oracles can also be used to connect blockchain networks to other systems, such as databases, smart contracts, and exchanges. #cryptodecoded
