# Layered Security

VIA Labs' cross-chain network uses a multi-layered validation process to ensure the security and integrity of transactions. This decentralized approach protects against unauthorized or fraudulent messages by requiring consensus across multiple independent layers.

### **VIA Layer**

* **Operated by VIA Labs**: This layer validates transactions within the VIA Labs ecosystem.
* **Proof of Authority**: No stake required. Validation rewards not given.

### **Chain Layer**

* **Managed by Blockchain Foundations**: Each blockchain involved (e.g., Blockchain A) manages its own validation layer.
* **Independent Validation**: Ensures that messages exiting the blockchain are verified.
* **Proof of Authority**: No stake required. Validation rewards not given.

### **Project Layer**

* **Project-Level Operation**: Integrating dApps can operate their own private validation layer.
* **Dedicated Security**: Provides additional security tailored to the specific needs of the project.
* **Proof of Authority**: No stake required. Validation rewards not given.

### **PoL Layer - Coming Soon**

* **Community-Driven**: Open to individuals, decentralized applications (dApps), and foundations.
* **Staking Requirement**: Participants must stake $VIA tokens to participate.
* **Proof of Liquidity:** Stake is required. Validators earn rewards.

**Consensus Mechanism**: For a transaction to be processed, it must pass through all four layers. The PoL Layer verifies with a 51% consensus mechanism.&#x20;
