**BNB (Binance Coin): Detailed Description**
---
### **1. Overview**
**BNB** (formerly Binance Coin) is the native cryptocurrency of the **Binance ecosystem**, created by the Binance exchange in 2017. Initially launched as an ERC-20 token on Ethereum, BNB migrated to Binance’s proprietary blockchain, **BNB Chain** (formerly Binance Smart Chain), in 2020. BNB serves as the backbone of Binance’s decentralized finance (DeFi), NFT, and Web3 ecosystems, offering utility in transaction fees, governance, and staking.
- **Native Blockchain**: BNB Chain (comprising **BNB Beacon Chain** for governance and **BNB Smart Chain** for smart contracts).
- **Market Position**: Consistently ranked among the top 5 cryptocurrencies by market cap.
- **Key Features**: Ultra-low fees, high throughput, and deep integration with the Binance ecosystem.

### **2. Key Features**
#### **a. Utility within Binance Ecosystem**
- **Transaction Fee Discounts**: Users pay fees on Binance Exchange with BNB for discounts (up to 25% historically).
- **Launchpad Participation**: Required to participate in token sales on Binance Launchpad.
- **BNB Chain Gas Fees**: Powers transactions, DeFi, and dApps on BNB Smart Chain.
#### **b. BNB Chain Architecture**

#### **c. Token Burns**

- Current supply: ~153 million BNB (as of July 2024).
- Target: 100 million BNB (50% of initial supply burned over time).
#### **d. Cross-Chain Interoperability**
