## Unraveling the Layers of LayerZero
At the core of **LayerZero's** prowess are **"Ultra Light Nodes" (ULNs)**. Picture these as nimble blockchain messengers, validating transactions across chains without the baggage of downloading the entire blockchain. This results in lightning-fast communication, ensuring your transactions are swift and secure.
### 1. Your Blockchain Gateway:
- **LayerZero** acts as your user-friendly, configurable on-chain endpoint, housing the powerful ULNs.
### 2. Dynamic Duo: Oracle and Relayer:
- Meet the dynamic duo of **LayerZero** - the Oracle and Relayer. They work in tandem to seamlessly transfer messages between on-chain endpoints.
### 3. Message Magic:
- Your messages travel through the magic portal of the endpoint on chain A, guided by the Oracle and Relayer to reach their destination on chain B.
### 4. Header Heroes and Proof Protectors:
- The Oracle heroically forwards the block header to chain B, while the Relayer submits the proof – ensuring your transactions are protected and validated.
### 5. Validation Voyage:
- The destination chain validates the proof, completing the journey by forwarding the message to the target address.
