What Is Fractal Bitcoin? (2025.11)

This is a great question — and one we haven't always answered clearly or concisely.

If you follow @fractal_bitcoin, you may have noticed that our profile description recently changed to:

Fractal Bitcoin — Extending the Utility of Bitcoin.

Fractal Bitcoin is a blockchain built with a modern design mindset, while remaining fully aligned with the core mechanisms of Bitcoin.

It can be understood from five different perspectives:

1. Fractal is a simple, flexible, fast, and robust extension of Bitcoin.

• Simple — It uses native Bitcoin code, without adding extra data layers or abstractions.
• Flexible — It can support protocols such as BRC-20 and Runes at any time, using the same mechanism as Bitcoin mainnet.
• Fast — Instead of Bitcoin's 10-minute block time, Fractal confirms a block every 30 seconds — a 20× faster experience.
• Robust — It is secured by 90% of Bitcoin’s global hash power, offering strong and continuous security guarantees.

2. Fractal is the core blockchain of UniHexa and the data backbone of BAI.

• For UniHexa — a next-generation hybrid trading engine built on Bitcoin — Fractal supports it on both the technical and asset layers.
• Fractal serves as the primary chain for BAI data, and may become an effective on-chain source for future oracle systems.
