# Introduction

**BuilDex (BDX)** is a decentralized perpetual exchange built on Binance Smart Chain (BSC).\
The key distinction of BuilDex is the use of **private pools (Dark Pools)** combined with **zero-knowledge proofs (ZK-proofs)**.

This architecture ensures:

* hidden trades and liquidations, eliminating the risk of attacks on large traders;
* verifiable fairness of all calculations through zk-proofs;
* protection against market manipulation and front-running.
