1. Introduction

Fractal Bitcoin is the only Bitcoin scaling solution that uses the Bitcoin Core code itself to recursively scale to unlimited levels, built on the world’s most secure and widely held blockchain.

To fully understand Fractal’s innovation, it is necessary to understand the historical context of Bitcoin’s scaling discussions. In 2017, the Segregated Witness (SegWit) soft fork aimed to increase Bitcoin’s block capacity, followed by the controversial Bitcoin Cash hard fork. Forks have emerged as another method of scaling. Since 2018, more and more attention has turned to second-layer solutions such as the Lightning Network. In this ongoing exploration of Bitcoin scalability and functionality enhancements, In the process, Fractal stood out as a new approach that provided a unique perspective on these long-standing challenges.

As an important milestone, Fractals mainnet was officially launched at 00:00 UTC on September 9, 2024.

The launch was a significant success, demonstrating the strong appeal and technical robustness of the project. Within just 24 hours of the mainnet launch, Fractal’s joint mining accounted for more than 40% of Bitcoin’s total computing power, and Fractal Free mining on Fractal accounts for 2% of Bitcoin’s hashrate. To put this data in context, Fractal’s free mining hashrate is more than three times the total hashrate of Bitcoin Cash (BCH). This rapid adoption by miners , showing a high level of confidence in Fractal technology and its potential.

In addition, there are other well-known mining pools ready to participate, which shows that Fractal mining is Interest in the network is increasing and has the potential to expand further.

2. Core concepts and technologies

2.1 Native Bitcoin Extensions

As a native extension of Bitcoin, Fractal’s approach sets it apart from other scaling solutions. By leveraging Bitcoin’s existing codebase and making modifications to block production parameters, Fractal maintains full compatibility with the Bitcoin mainnet. Ensure seamless integration with existing infrastructure. This approach enables feature enhancements without affecting the core Bitcoin security model, striking a balance between innovation and maintaining Bitcoins fundamental principles.

2.2 Technical specifications

Fractal introduces several key technical innovations:

• Block time: Fractal achieves a 30 second block time, which is a significant improvement over Bitcoin’s 10 minute block time. This faster block time allows transactions to be confirmed more quickly, greatly improving In addition, it significantly increases the overall throughput of the network, potentially supporting a wider range of complex applications that require high transaction volumes.

• Mining mechanism: Fractal uses a unique hybrid mining method. Two out of every three blocks are permissionless mining, and one is merged mining with Bitcoin. This innovative mechanism allows individuals to Miners freely participate in two-thirds of the block production, encouraging decentralization. At the same time, it enhances security by leveraging Bitcoin’s strong computing power through joint mining of every third block. This balance This approach aims to maintain network security and decentralization and incentivize existing Bitcoin miners to support the Fractal network.

• Scalability: Fractal’s architecture theoretically supports unlimited layers of improvements. Each Fractal layer provides 20 times the capacity of Bitcoin mainnet. This means that the base layer provides 20 times the capacity of Bitcoin, and the second layer will Providing 400 times the capacity. This exponential scalability model allows Fractal to address Bitcoin’s throughput limitations while maintaining base layer security properties.

• Smart Contract Functionality: By implementing the OP_CAT opcode, Fractal enables Turing-complete smart contracts on a Bitcoin-based platform. OP_CAT is a simple connection operation that, combined with other opcodes, can implement complex smart contract logic. The functionality opens up possibilities for advanced DeFi protocols, complex NFT mechanisms, and other decentralized applications that were previously limited to the Ethereum platform.

• Parallel execution: Fractal’s architecture allows different applications to run their own instances, so that specific optimizations do not affect the entire network. For example, a gaming platform can run on a specially optimized Fractal layer for high-frequency, low-value transactions. The DeFi protocol can use an independent layer of parameter tuning to perform financial operations.

• Compatibility: Fractal maintains 100% compatibility with Bitcoin standards such as BRC-20 and Ordinals. This ensures that existing Bitcoin tokens and NFTs can operate seamlessly. In addition, users can use Fractal on both the Bitcoin mainnet and Using the same address across Fractals simplifies the user experience and reduces the risk of errors in address management.

Lorenzo, founder of UniSat and core contributor to Fractal, outlined his vision in response to community questions.

2.3 Unique User Experience

Unlike other Bitcoin Layer 2 solutions, the wallet address on Fractal is exactly the same as the mainnet address. This design provides convenience similar to Ethereum, where users can access different wallets by simply switching networks in UniSat or OKX wallets. Unlike other Bitcoin Layer 2 solutions that require a separate EVM wallet address, Fractal allows users to continue using the Bitcoin mainnet address in Layer 2 activities. As of now, major wallets such as OKX Wallet and UniSat Wallet serve Most active Bitcoin DeFi and collectibles users fully support Fractal Bitcoin.

3. Fractal’s position in the Bitcoin ecosystem

3.1 Comparison with other Bitcoin solutions

Fractal enters a competitive market for Bitcoin scaling solutions. Here’s how it compares to some of the main alternatives:

• EVM-compatible Layer 2: Some projects attempt to create EVM-based second-layer solutions for Bitcoin. While these solutions are relatively easy to implement and launch, they face significant challenges in terms of acceptance by the Bitcoin community. Especially its core users and developers, often regard these EVM-compatible solutions as stitched. In contrast, Fractal takes a Bitcoin-native approach, aiming to expand Bitcoins capabilities without introducing external This approach may be more in line with the philosophy of Bitcoin purists and may lead to better integration and adoption within the existing Bitcoin ecosystem.

• Bitcoin Cash (BCH): Bitcoin Cash emerged as a hard fork of Bitcoin, aiming to improve scalability through a larger block size. This approach led to divisions within the Bitcoin community and forced users to The BCH fork has sparked a lot of political debate, often overshadowing the technical discussions. In contrast, Fractal takes a fundamentally different approach. It does not create Instead of forcing users to choose a separate chain or a separate chain, Fractal embraces Bitcoin as the mainnet and seeks to scale it natively. Fractal’s architecture allows for the creation of multiple instances that scale together, potentially without sacrificing the security or decentralization of the base layer. Under the premise of providing unlimited scalability.

• Lightning Network: Lightning Network excels in fast, low-cost payments and high privacy, but its smart contract functionality is limited and faces channel liquidity issues. In contrast, Fractal provides comprehensive smart contract support. , no channel management is required, providing a simpler user experience.

3.2 Marketing Strategy and Built-in User Base

Fractal stands out in the competitive Layer 2 space not only through technological innovation, but also through a strategic market approach and a strong built-in user base. Backed by UniSat, a leading Bitcoin wallet with approximately 1 million Bitcoins per user, Fractal is a leader in the Bitcoin industry. Weekly Active Users, which enables Fractal to reach an already engaged audience.

Many UniSat users already hold assets such as BRC 20 tokens and Runes in their wallets. These users naturally want a cheaper, faster, and more feature-rich trading environment. Fractal can directly meet this demand and provide improved trading experience while maintaining familiarity and compatibility with the Bitcoin ecosystem that these users are accustomed to.

This built-in user base gives Fractal a significant advantage over other Layer 2 solutions and new blockchain platforms, which often face the “cold start” problem of attracting an initial user base and building network effects from scratch. By leveraging UniSats existing user base, Fractal may be able to circumvent early adoption barriers.

In addition, Fractal’s strategy on growth metrics also distinguishes it from many other blockchain projects. While many Layer 2 solutions and new blockchains consider total locked value (TVL) as a core metric, Fractal plans to use the number of transactions as a core metric. This strategy is aligned with its native user base, which is likely to generate a large number of transactions naturally as they interact with existing assets on a more efficient platform.

By focusing on transaction volume rather than TVL, Fractal is able to demonstrate real usage and adoption, which may be more attractive to users and investors in the long run. This strategy also makes Fractal stand out from other projects that focus on TVL numbers. Stand out from the crowd.

7. Challenges and risks

While Fractal presents an innovative approach to extending Bitcoin’s functionality, it also faces challenges that potential investors and users need to consider:

Programmability is the main challenge facing Fractal. Since it is 100% compatible with the Bitcoin mainnet, Fractal is programmed using Bitcoin Script, which may hinder the growth of the ecosystem. To better understand this issue According to Electric Capital’s developer report, Bitcoin has 1,071 monthly active developers, while Ethereum has 7,864 monthly active developers.

Bitcoin Script is not as well-known as popular languages like Rust or Solidity, and is more challenging to use, which may lead to a small number of developers. Fractal has a high coding threshold, and its functionality may not be as good as other blockchains, which may Slowing down the speed of ecosystem expansion. In addition, compared with other blockchain environments, the development tools, libraries, and frameworks of Bitcoin Script are relatively immature, which may further hinder the development and deployment of applications on Fractal.

Technical risks also pose significant challenges. Modifying Bitcoin’s core parameters and implementing new features such as OP_CAT inherently carries the risk of introducing vulnerabilities or unintended consequences. Managing recursive extensions and multiple levels of complexity adds to the technical challenges.

Adoption risk is another significant challenge. Fractal may face resistance from Bitcoin maximalists who believe that any modification or extension to Bitcoin is unnecessary or potentially harmful. Convincing users and developers to move away from established Layer 2 It may be difficult for other blockchain platforms to switch to Fractal, especially given the network effects of these existing solutions. In addition, despite Fractal compatibility, the Runes, Ordinals, and BRC-20 communities may be reluctant to adopt the same standards. These communities Already established ecosystems may not see enough incentive to migrate or expand to a new platform, even if it offers better performance. Fractal needs to clearly articulate its value proposition and potentially offer significant incentives to drive these users The challenge is not only to deliver a technological advantage, but also to overcome the inertia of the established community and their existing investments in the current platform.

To address these challenges, especially the issue of programmability, Fractal will likely need to invest significantly in developer education, create robust development tools, and possibly explore ways to make the development process more accessible without compromising its integration with Bitcoin Core.
