紐約，2023 年 3 月 3 日 – 全球全像擴增實境 (AR) 技術領導者微美全像 (NASDAQ: WIMI) 宣布成功將 RAFT 共識演算法整合到區塊鏈系統中，旨在確保資料的穩健性一致性並提高整體性能。

RAFT: Achieving Distributed Consistency with Simplicity

RAFT：簡單地實現分散式一致性

The RAFT consensus algorithm is renowned for its simplicity and effectiveness in maintaining distributed consistency. It is particularly suited for environments that demand stringent performance and determinism, such as federated chains, private chains, and specific blockchain components. The algorithm's technical advantages lie in its efficient log replication and rapid data synchronization capabilities.

RAFT 共識演算法以其簡單性和維護分散式一致性的有效性而聞名。它特別適合需要嚴格性能和確定性的環境，例如聯邦鏈、私有鏈和特定的區塊鏈組件。此演算法的技術優勢在於高效的日誌複製和快速的資料同步能力。

Leader-Follower Architecture for Enhanced Efficiency

用於提高效率的領導者-跟隨者架構

RAFT employs a Leader-Follower architecture, where a designated active leader node manages client requests and log replication. This centralized approach simplifies system state management and fosters efficient decision-making. The leader node can swiftly address client requests, obviating the need for time-consuming negotiations between nodes, a common feature in traditional consensus mechanisms. This design significantly enhances the system's decision-making efficiency.

RAFT 採用 Leader-Follower 架構，其中指定的主動領導節點管理用戶端請求和日誌複製。這種集中式方法簡化了系統狀態管理並促進高效的決策。領導節點可以快速處理客戶端請求，從而避免了節點之間耗時的協商，這是傳統共識機制的共同特徵。這種設計顯著提高了系統的決策效率。

In the event of a leader node failure or network partitioning, RAFT's election mechanism swiftly selects a new leader, adhering to strict rules to prevent competitive conflicts among nodes. This process ensures high system availability and stability, minimizing the risks of prolonged leadership vacancies or double spending issues.

當Leader節點發生故障或網路分區時，RAFT的選舉機制會迅速選出新的Leader，並遵守嚴格的規則來防止節點之間的競爭衝突。此流程可確保系統的高可用性和穩定性，最大​​限度地降低領導層長期空缺或雙重支出問題的風險。

Ensuring Data Consistency Across Nodes

確保跨節點資料一致性

The leader node in the RAFT algorithm serially records incoming client requests into a log and replicates these entries to all follower nodes. RAFT maintains the sequential consistency of logs across different nodes through rigorous mechanisms. Log entries are considered committed once confirmed by the majority of nodes, guaranteeing global data consistency. This mechanism ensures a consistent evolution of node states, even during network partitions or node failures.

RAFT 演算法中的領導節點將傳入的用戶端請求連續記錄到日誌中，並將這些條目複製到所有跟隨節點。 RAFT透過嚴格的機制來維護不同節點間日誌的順序一致性。日誌條目經大多數節點確認後即視為已提交，確保全域資料一致性。即使在網路分區或節點故障期間，此機制也可確保節點狀態的一致演進。

Applications and Benefits of RAFT in Blockchain Systems

RAFT 在區塊鏈系統中的應用與優勢

The integration of RAFT into WiMi's blockchain system architecture offers substantial performance and reliability enhancements. Its application scenarios include:

將 RAFT 整合到微美的區塊鏈系統架構中可顯著提高效能和可靠性。其應用場景包括：

• Achieving efficient consensus within alliance and private chain environments
• Optimizing performance in sidechain and subchain designs
• Enhancing the reliability of system components

In alliance and private chain projects, where participating nodes are strictly verified and limited in number, RAFT's robust leadership mode ensures rapid consensus, significantly reducing transaction confirmation times and efficiently handling highly concurrent transactions. The orderly log replication mechanism ensures precise synchronization of node statuses, fundamentally improving data consistency and system reliability.

在聯盟和私鏈環境下實現高效共識優化側鍊和子鏈設計性能增強系統組件的可靠性在聯盟和私鏈項目中，參與節點經過嚴格驗證和數量限制，RAFT穩健的領導模式保證了快速共識，大幅減少交易確認時間並有效處理高度並發的事務。有序的日誌複製機制保證了節點狀態的精確同步，從根本上提高了資料的一致性和系統的可靠性。

For multi-chain architectures, RAFT can provide efficient internal consensus services for sidechains or subchains. These sidechains specialize in specific transaction types and business logic and interact with the main chain through cross-chain protocols. RAFT empowers these sidechains to process relevant transactions independently and expeditiously, alleviating the burden on the main chain and boosting overall system scalability. Moreover, RAFT ensures data consistency within the sidechains, preventing business disruptions caused by data inconsistency.

對於多鏈架構，RAFT可以為側鍊或子鏈提供高效率的內部共識服務。這些側鏈專注於特定的交易類型和業務邏輯，並透過跨鏈協議與主鏈互動。 RAFT 使這些側鏈能夠獨立、快速地處理相關交易，減輕主鏈的負擔，並提高整個系統的可擴展性。此外，RAFT也保證了側鏈內資料的一致性，防止因資料不一致而導致業務中斷。

Furthermore, the RAFT algorithm can be utilized in key blockchain components, such as storage modules and management services, to guarantee data consistency within those elements. For instance, RAFT can manage replicated state machines to ensure that each node state machine executes the same instructions in the same order, thereby preventing state divergence. In management services, RAFT ensures synchronous updates to system configuration information, preventing service interruptions or data confusion caused by configuration inconsistencies.

此外，RAFT演算法可以用於關鍵的區塊鏈組件，例如儲存模組和管理服務，以確保這些元素內的資料一致性。例如，RAFT可以管理複製的狀態機，以確保每個節點狀態機以相同的順序執行相同的指令，從而防止狀態發散。在管理業務中，RAFT保證系統配置資訊的同步更新，防止因配置不一致而導致業務中斷或資料混亂。
