To understand it, you first need to know that blockchains cannot access information from the real world by themselves. This is where oracles come in, acting as bridges between the blockchain and the outside world.

What are oracles for and what importance do they have?Oracles, as I mentioned earlier, transmit real-world information to the blockchain, allowing smart contracts to make decisions based on external data, such as: cryptocurrency prices, weather conditions, results...

Introduction:
In the blockchain ecosystem, trust in external information is vital for smart contracts to function correctly. This is where oracles come in: services that allow smart contracts to access real-world data, such as asset prices, sports outcomes, or weather conditions. While Chainlink has been the leader for several years, a new player has emerged with strength: Pyth Network ($PYTH ).

What is Pyth Network?
Pyth is a decentralized oracle designed to provide real-time financial data directly from sources (such as centralized exchanges and trading platforms). Its approach eliminates intermediaries, improving the speed, accuracy, and security of the data received by smart contracts.

In the world of decentralized finance (DeFi), oracles play a fundamental role in connecting smart contracts with real-world data. Without them, DeFi applications could not access external information, limiting their functionality.
Let's see how they work and why they are essential for the DeFi ecosystem.
What are oracles in blockchain?
An oracle is a bridge between blockchains and the outside world. Smart contracts, by design, can only access data within their own network, meaning they cannot directly interact with external information, such as asset prices, sports results, or weather conditions.
