When you participate in decentralized finance (DeFi) activities, most events occur "on-chain." On-chain resources refer to data currently recorded on a blockchain. But what if you want to do things outside of an external network?

Say, for example, that you want to bet coins on a big sports game. You can create a smart contract, but how does that contract know to pay the winner after the game?

That's where a first party oracle comes in.

Blockchain Oracle Basics

The best way to look at an oracle is to consider it middleware.

Smart contracts are the foundation of decentralized finance. These contracts are simple programs that run on the blockchain when certain conditions meet. In the case of the sports game bet example, the smart contract would run after the game to pay the winner.

But here's the problem: They can't connect with systems outside the native blockchain. Blockchains are inherently closed off. Most of their benefits are possible because they're separate from external systems. That's the entire point of being decentralized.

However, smart contracts need a way to pull data from the real world. It's essential for DeFi. Without access to data that can verify the conditions of the contract, they wouldn't exist.

Oracles are the bridge. They bridge the gap between a blockchain network and off-chain resources. The oracle helps access relevant information while maintaining the blockchain's key security features. Think of it as a digital intermediary.

The data will route through an external transaction within the oracle. Many oracles are available, and Chainlink is one of the most common. However, blockchains can also have a first party oracle and accept unique tokens as payment for their services.

Oracles and Security

One of the things that make blockchain technology so compelling is its security. Oracles are a critical piece of the smart contract puzzle, but they can also open the doors to security risks. Anything connected to the off-chain world is hackable, and security breaches can impact how smart contracts work.

Fortunately, there are many ways to implement a safe oracle. The key is to pair the intermediary with trusted external sources to avoid security risks.
