# Oracles Oracles play a pivotal role in Hashi’s ecosystem. They are responsible for relaying block headers and messages between blockchains and validating them in a decentralized manner. Hashi uses multiple oracles to ensure security and avoid relying on a single point of failure. * **Why Multiple Oracles?**\ Trusting a single oracle can introduce vulnerabilities, especially in cross-chain environments where security is critical. Hashi solves this by using multiple oracles, each independently verifying the data. Only when consensus is reached among a majority of these oracles is the data accepted, significantly reducing the risk of manipulation or failure. * **Supported Oracles**\ Hashi is designed to work with various oracles, you can find a list of supported ones [here](/hashi/deployments/oracles.md). These oracles are integrated into Hashi’s framework to ensure compatibility across a range of blockchain environments. * **Oracle Adapters**\ Hashi uses a universal adapter interface, making it easy to add support for new oracles as they emerge. This flexibility allows Hashi to evolve with the ecosystem, accommodating new oracle solutions as needed. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://crosschain-alliance.gitbook.io/hashi/core-concepts/oracles.md?ask= ``` The question should be specific, self-contained, and written in natural language.
