# Introduction

Welcome to the official documentation for **QuantaChain V2**, the first Post-Quantum Institutional Settlement Layer built with AlephBFT consensus and Falcon-512 lattice signatures.

## What is Quanta V2?

Quanta V2 is a massive architectural upgrade from the V1 era. It completely removes Proof-of-Work mining in favor of **Asynchronous Byzantine Fault Tolerance (AlephBFT)**, providing deterministic 6-second block finality.

### Key Features

* **AlephBFT Consensus:** 6-second deterministic block times. Once a block is committed, it is instantly final.
* **Post-Quantum Cryptography:** All network signatures utilize **Falcon-512**, and wallets are encrypted via **Kyber-1024**.
* **AI Agent Native:** Transactions include a `payload` field signed by Falcon-512. The `quanta-wallet` supports headless execution via the `QUANTA_WALLET_PASSWORD` environment variable, enabling AI agents to autonomously hold and transfer funds via Escrow contracts.
* **Institutional Treasury:** Native 3-of-N Multisig (Falcon-512) for secure treasury management.
