# Welcome

Welcome to the official documentation for **Hashi**, your comprehensive guide to understanding and integrating the Hashi oracle aggregator into your cross-chain applications. Whether you're new to cross-chain security or an experienced developer looking to enhance the security of your blockchain projects, this guide will provide you with all the necessary tools and insights.

Hashi is designed to **increase the security** of cross-chain interactions by utilizing multiple oracles to verify and validate block headers and messages between chains. By ensuring that cross-chain messages are validated by multiple independent oracles, Hashi mitigates risks associated with single points of failure and enhances the overall security of decentralized ecosystems.
