Introduction

Overview and Purpose Fast Chain is designed to empower Bitcoin’s value by enabling rapid, low-cost transactions on a high-performance Layer 2. Unlike conventional BTC solutions, Fast Chain is built on the mature BNB L2 security architecture. By using binance-peg BTCB as its native token, Fast Chain captures the intrinsic value of Bitcoin while delivering an operational efficiency that traditional BTC Layer 1 networks cannot match.

Concrete Technical Metrics

• Block Time: 1 second

• Transaction Throughput: Over 4000 TPS

• Cost Efficiency: Ultra-low transaction fees enabled by off-chain processing and optimized resource usage

• Ecosystem Integration: Native connectivity with the BNB Chain, allowing seamless interaction with a wide range of dApps and meme token platforms (e.g., Four.meme)

Our Mission Fast Chain’s mission is to transform Bitcoin into a truly dynamic asset for DeFi and beyond. We aim to provide an industry-leading BTC Layer 2 solution that delivers both tangible performance improvements and seamless integration with the broader Binance ecosystem.
