# Key Features

Hashi introduces a range of features designed to enhance the security and flexibility of cross-chain applications. Here’s a brief overview of what sets Hashi apart:

#### **1. Multi-Oracle Validation**

Hashi aggregates data from multiple independent oracles to validate block headers and messages. This reduces reliance on a single oracle and increases the security of cross-chain interactions.

#### **2. Secure Block Relaying**

Hashi relays entire block headers between chains, providing cryptographic proof of blockchain states across multiple networks. This ensures that data being relayed is both secure and verifiable.

#### **3. Abstraction Layer for Oracles**

Hashi acts as an abstraction layer, allowing you to easily switch between different oracles without being locked into a single provider. This flexibility helps avoid vendor lock-in and future-proofs your application.

#### **4. Additive Security Model**

With Hashi, security scales as more oracles are added to the validation process. This makes Hashi adaptable to a variety of applications, from low-risk operations to high-value transactions that require additional layers of security.

#### **5. Cross-Chain Compatibility**

Hashi supports a wide range of blockchains and oracle systems, making it a versatile solution for developers building cross-chain applications.
