Day 12 — Mastering Ethereum (Oracles)
Smart contracts on Ethereum cannot access real-world information or generate true randomness on their own because all computers in the network must reach the same result.
To solve this, oracles are used. Oracles act as bridges that bring outside information such as prices, weather, random numbers, or events from other blockchains, into smart contracts.
Oracles make smart contracts more useful, allowing them to react to real-life events. However, they also introduce risk because if an oracle is hacked or dishonest, the smart contract can behave incorrectly.
