分形比特幣能否突破比特幣鏈上計算能力的限制

介紹：比特幣作為當前牛市週期的核心驅動力，其相關概念備受關注。隨著比特幣生態系統的不斷發展和完善，可擴展性問題日益突出，分形比特幣的概念應運而生。這一創新理念最初由Unisat團隊提出，旨在探索比特幣網絡的可擴展性可能性。然而，分形比特幣並不嚴格屬於比特幣的第二層解決方案（L2），其本質更接近於側鏈結構。

分形比特幣的定義和核心特徵

分形比特幣是一種基於遞歸虛擬化技術的創新區塊鏈擴展解決方案，通過創建多層網絡結構來增強比特幣的可擴展性，同時保持與主網的安全連接。

核心特徵：

1) 遞歸虛擬化：

分形比特幣使用遞歸虛擬化技術在比特幣區塊鏈上創建多個層級。每個層級作為獨立實例運行，但錨定於主比特幣網絡，以確保整個網絡的安全性和共識機制。

2) 無限可擴展性：

通過不斷創建新層級，分形比特幣可以處理不斷增長的交易量和數據量，而不會導致網絡擁堵。這使其能夠適應區塊鏈技術日益普及所帶來的處理能力和存儲需求的增加。

3) 動態負載平衡：

分形比特幣可以根據實時需求動態分配資源，將交易分散到不同層級。此功能防止單一層級成為性能瓶頸，確保即使在高峰使用期間也能平穩運行。

4) 安全性和一致性：

分形比特幣是比特幣的一個分支，而不是直接擴展。它採用工作量證明（PoW）共識機制，並將其應用於所有層級。這確保了整個網絡的安全性和一致性，享有與比特幣相同的信任和可靠性。

更快的區塊確認。

與比特幣通常10分鐘的區塊確認時間相比，分形比特幣將確認時間縮短至30秒或更少。這大大提升了用戶體驗，支持高頻應用和交易。

高效的資產橋接。

分形比特幣引入了強大的資產橋接能力，允許用戶在不同網絡層之間安全地轉移各種數字資產，而無需封裝代幣，從而保持資產的完整性和可用性。

總體而言，分形比特幣在增加可擴展性的同時，保持了比特幣網絡的基本安全性和可靠性。

 

分形比特幣的背景

分形比特幣的創建背景起源於2023年。Ordinals及相關應用的出現引起了廣泛關注，將開發者的注意力轉向比特幣的廣泛應用潛力。然而，出於安全考慮，比特幣在其迭代中對操作碼和區塊存儲空間實施了限制。為了解決比特幣區塊鏈的固有限制，特別是在鏈上計算能力和區塊空間方面，提出了分形比特幣的概念。

在數學中，分形圖案在每個尺度上重複，這一原則在分形比特幣的架構中得以體現。每一層都可以看作是整個網絡的一個較小的複製品， capable of infinite expansion to accommodate more users and transactions. This not only ensures that the network remains efficient and fast, but also provides a powerful framework for future growth and innovation. Some solutions for Bitcoin L2 are more like building a sidechain, requiring cross-chain operations, so developers seek to enhance its functionality without compromising core principles as the optimal solution.

Of course, the introduction of technologies such as SegWit and TapRoot has made it possible for this idea to be implemented, thereby improving the programmability and efficiency of Bitcoin. It has also laid the foundation for exploring more complex solutions to improve the scalability and practicality of Bitcoin.

 

Technology Implementation and Other Scaling Solutions of Fractal Bitcoin

Create multiple independent levels on the Bitcoin blockchain. Each level operates as an independent instance, but is still anchored to the main Bitcoin network. This layered architecture allows fractal Bitcoin to distribute transaction loads, and each layer can handle a large number of transactions simultaneously. To manage these levels, fractal Bitcoin implements a dynamic load balancing system. This system can flexibly allocate resources and allocate transactions based on fluctuations in transaction demand, preventing any single level from becoming a bottleneck. To achieve cross-level asset transfer, fractal Bitcoin adopts a rotating multi-party computation (MPC) signature system. This system allows efficient and secure asset transfer without users packaging their tokens, maintaining the integrity and availability of assets within the ecosystem.

In practical applications, fractal Bitcoin creates dedicated instances for specific purposes. For example, it creates dedicated instances for ordinals, ensuring 100% compatibility and optimizing the handling of these assets. This dedicated instance adopts a mechanism to lock and map specific satoshis on the main chain to instances, allowing ordinals to flow seamlessly within instances while ensuring that they retain their original inscriptions when returning to the main chain.

Overall, by separating these transactions from the main network, fractal Bitcoin reduces potential friction while maintaining the purity of Bitcoin's main use cases.

 

Sidechain Technology: Expanding the Possibilities of Bitcoin

Sidechain technology achieves this goal by creating an independent blockchain that can interoperate with the Bitcoin main network. This mechanism allows users to deposit their bitcoins into contracts on the Bitcoin blockchain, and then create an equal amount of bitcoins for use on the sidechain. This bidirectional anchoring not only enhances the functionality of Bitcoin, allowing for experimentation with new features and applications without changing the main network, but also solves scalability issues by transferring transactions away from the main blockchain. Sidechains can support various use cases, such as smart contracts and decentralized applications, thereby expanding the practicality of Bitcoin and promoting innovation within its ecosystem.

 

Lightning Network: Layer 2 Solution

Lightning Network, as a key second-layer solution, allows multiple off-chain transactions to occur instantly by creating a two-way payment channel between users, significantly reducing congestion issues typically associated with the Bitcoin main blockchain. This innovative approach not only reduces transaction fees - making microtransactions economically feasible - but also improves the overall User Experience通過消除鏈上交易的長確認時間。

 

閃電網絡的路由系統甚至可以促進沒有直接支付通道的用戶之間的支付，類似於互聯網數據包的路由方式，從而提高支付過程的效率。因此，閃電網絡將自己定位為解決比特幣擴展性挑戰的變革性解決方案，使其成為日常交易的實用選擇，並促進加密貨幣在日常商務中的更廣泛採用。閃電網絡的實施為比特幣生態系統帶來了許多好處。它不僅增強了比特幣作為支付方式的功能，還開闢了新的應用可能性，例如微支付。
