纽约，2023 年 3 月 3 日 – 全球全息增强现实 (AR) 技术领导者微美全息 (NASDAQ: WIMI) 宣布成功将 RAFT 共识算法集成到区块链系统中，旨在确保数据的稳健性一致性并提高整体性能。

RAFT: Achieving Distributed Consistency with Simplicity

RAFT：简单地实现分布式一致性

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 共识算法以其简单性和维护分布式一致性的有效性而闻名。它特别适合需要严格性能和确定性的环境，例如联邦链、私有链和特定的区块链组件。该算法的技术优势在于高效的日志复制和快速的数据同步能力。

Leader-Follower Architecture for Enhanced Efficiency

用于提高效率的领导者-跟随者架构

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 采用 Leader-Follower 架构，其中指定的主动领导节点管理客户端请求和日志复制。这种集中式方法简化了系统状态管理并促进高效的决策。领导节点可以快速处理客户端请求，从而避免了节点之间耗时的协商，这是传统共识机制的一个共同特征。这种设计显着提高了系统的决策效率。

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.

当Leader节点发生故障或网络分区时，RAFT的选举机制会迅速选出新的Leader，并遵守严格的规则来防止节点之间的竞争冲突。此流程可确保系统的高可用性和稳定性，最大​​限度地降低领导层长期空缺或双重支出问题的风险。

Ensuring Data Consistency Across Nodes

确保跨节点数据一致性

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 算法中的领导节点将传入的客户端请求连续记录到日志中，并将这些条目复制到所有跟随节点。 RAFT通过严格的机制维护不同节点间日志的顺序一致性。日志条目经大多数节点确认后即视为已提交，保证全局数据一致性。即使在网络分区或节点故障期间，该机制也可确保节点状态的一致演变。

Applications and Benefits of RAFT in Blockchain Systems

RAFT 在区块链系统中的应用和优势

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

将 RAFT 集成到微美的区块链系统架构中可显着提高性能和可靠性。其应用场景包括：

• 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.

在联盟和私链环境下实现高效共识优化侧链和子链设计性能增强系统组件的可靠性在联盟和私链项目中，参与节点经过严格验证和数量限制，RAFT稳健的领导模式保证了快速共识，大幅减少交易确认时间并有效地处理高度并发的事务。有序的日志复制机制保证了节点状态的精确同步，从根本上提高了数据的一致性和系统的可靠性。

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.

对于多链架构，RAFT可以为侧链或子链提供高效的内部共识服务。这些侧链专注于特定的交易类型和业务逻辑，并通过跨链协议与主链交互。 RAFT 使这些侧链能够独立、快速地处理相关交易，减轻主链的负担，提高整个系统的可扩展性。此外，RAFT还保证了侧链内数据的一致性，防止因数据不一致而导致业务中断。

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算法可以用于关键的区块链组件，例如存储模块和管理服务，以保证这些元素内的数据一致性。例如，RAFT可以管理复制的状态机，以确保每个节点状态机以相同的顺序执行相同的指令，从而防止状态发散。在管理业务中，RAFT保证系统配置信息的同步更新，防止因配置不一致而导致业务中断或数据混乱。
