- Fractal Bitcoin launches its mainnet, leveraging Bitcoin Core code for improved scaling
- The network offers block confirmations within 30 seconds and claims up to 20x increased capacity
- The network’s native token FB supports proof-of-work mining, with half pre-minted for allocation
Fractal Bitcoin, an innovative scaling solution for Bitcoin, has officially launched its mainnet, marking a new chapter in Bitcoin scalability. The project—led by Unisat and Block Space Force—represents a significant technical advancement for the Bitcoin (BTC) ecosystem by building on the Bitcoin Core codebase.
Fractal Bitcoin uses iterative layering and integrates the OP_CAT opcode
The Fractal Bitcoin mainnet launch follows extensive testing on a testnet that began in July 2024. The network claims impressive performance metrics, including block confirmation times under 30 seconds and up to 20x capacity per layer. Unlike many other scaling solutions that rely on compatibility with the Ethereum Virtual Machine (EVM), Fractal Bitcoin emphasizes Bitcoin’s native architecture. Its approach focuses on enhancing Bitcoin’s inherent capabilities through recursive layer design and the integration of the OP_CAT opcode. This distinctive strategy aims to overcome limitations faced by traditional Bitcoin sidechains and many layer-2 solutions.
Beyond its core design, Fractal Bitcoin is compatible with several Bitcoin protocols such as BRC-20, Runes, and Ordinals. A notable feature of the mainnet rollout is PizzaSwap, a decentralized exchange built into the network intended to facilitate seamless trading and transactions within the ecosystem. The network also introduces a new mining model called “Cadence Mining.” This model combines permissionless mining with merged-mining alongside Bitcoin, strengthening network security and offering robust protection against potential threats.
The native token, FB
The Fractal Bitcoin mainnet launch includes the introduction of the network’s native token, FB, with a total supply of 210 million tokens. Half of the FB supply is allocated to proof-of-work mining, while the remaining half has been pre-mined for key contributors, investors, the ecosystem treasury, and community grants. This distribution model underscores the project’s commitment to fostering a supportive and thriving ecosystem.
Overall, the Fractal Bitcoin mainnet represents a notable step forward in Bitcoin scaling solutions. By leveraging Bitcoin Core, embracing native Bitcoin opcodes, and introducing novel features such as recursive layering, OP_CAT integration, PizzaSwap, and Cadence Mining, the project aims to enhance performance, security, and functionality for the broader Bitcoin community.
