Polkadot Unveils JAM Upgrade: A Journey Towards Decentralization

Polkadot 推出 JAM 升级：迈向去中心化之旅

In a pivotal move towards decentralization, Polkadot, the leading interoperability blockchain, has unveiled its Join-Accumulate Machine (JAM) upgrade, a significant overhaul designed to enhance the protocol's scalability, performance, and security.

在走向去中心化的关键一步中，领先的互操作性区块链 Polkadot 推出了加入累积机 (JAM) 升级，这是一项重大改革，旨在增强协议的可扩展性、性能和安全性。

The announcement, made by Polkadot founder Gavin Wood at the Token2049 crypto conference in Dubai, marks a significant milestone in Polkadot's evolution. The JAM upgrade aims to replace the existing relay chain, the central data backbone of the Polkadot network, with a more modular and flexible architecture.

Polkadot 创始人 Gavin Wood 在迪拜举行的 Token2049 加密会议上宣布的这一消息标志着 Polkadot 发展的一个重要里程碑。 JAM 升级旨在以更加模块化和灵活的架构取代现有的中继链（Polkadot 网络的中央数据主干）。

JAM: A Modular and Minimalist Design

JAM：模块化和简约的设计

Central to the JAM upgrade is its modular design, a departure from the current monolithic structure of the relay chain. This modular approach enables Polkadot to run generic services and expand its functionality, providing a more robust and adaptable platform for developers and users.

JAM 升级的核心是其模块化设计，与当前中继链的整体结构不同。这种模块化方法使 Polkadot 能够运行通用服务并扩展其功能，为开发人员和用户提供更强大、适应性更强的平台。

The parachains service within JAM will seamlessly integrate with existing Substrate-based parachains, allowing developers to continue leveraging Substrate's comprehensive toolset to develop and deploy their blockchains. These services will possess no predefined limits on code, data, or state capacity, offering developers the freedom to explore innovative applications and solutions.

JAM 中的平行链服务将与现有的基于 Substrate 的平行链无缝集成，使开发人员能够继续利用 Substrate 的综合工具集来开发和部署他们的区块链。这些服务对代码、数据或状态容量没有预定义的限制，为开发人员提供探索创新应用程序和解决方案的自由。

Technical Advancements Driving Performance

技术进步推动性能

The JAM upgrade introduces several technical advancements to optimize network performance and scalability. It replaces WebAssembly with the Polkadot Virtual Machine based on the RISC-V ISA (instruction set architecture), an open-source design widely used in custom processor development. This substitution enhances the network's efficiency and reduces computational overhead.

JAM 升级引入了多项技术进步，以优化网络性能和可扩展性。它用基于 RISC-V ISA（指令集架构）的 Polkadot 虚拟机取代了 WebAssembly，RISC-V ISA 是一种广泛用于定制处理器开发的开源设计。这种替代提高了网络的效率并减少了计算开销。

Additionally, JAM incorporates SAFROLE, a SNARK-based block production algorithm, a cryptographic technique that enables efficient and secure block production. These upgrades collectively contribute to the overall performance and stability of the Polkadot network.

此外，JAM 还采用了 SAFROLE，这是一种基于 SNARK 的区块生产算法，这是一种能够实现高效、安全的区块生产的加密技术。这些升级共同提升了 Polkadot 网络的整体性能和稳定性。

Decentralization at the Core

核心权力下放

To fully realize Polkadot's vision of a truly decentralized protocol, the JAM upgrade supports multiple client implementations, a fundamental aspect of ensuring network robustness. The establishment of the JAM Implementer's Prize, a 10 Million DOT prize pool, serves as a catalyst for fostering diverse development efforts and incentivizing the creation of new client implementations.

为了充分实现 Polkadot 真正去中心化协议的愿景，JAM 升级支持多种客户端实现，这是确保网络稳健性的一个基本方面。 JAM 实施者奖的设立是一个 1000 万 DOT 奖池，可作为促进多样化开发工作和激励创建新客户实施的催化剂。

"We believe that supporting a range of implementations in various programming languages will strengthen the ecosystem's foundation," said Wood during his presentation. "It distributes the power of protocol implementers more widely and reduces the risk of a bug in one implementation taking down the entire network."

“我们相信，支持各种编程语言的一系列实现将加强生态系统的基础，”伍德在演讲中说道。 “它更广泛地分配了协议实施者的权力，并降低了一个实施中的错误导致整个网络瘫痪的风险。”

The JAM Implementer's Prize will collaborate with existing and future funding initiatives within the Polkadot ecosystem, providing comprehensive support for protocol development. It will become active upon JAM's ratification as a Polkadot technology through the network's on-chain governance mechanism.

JAM 实施者奖将与 Polkadot 生态系统内现有和未来的资助计划合作，为协议开发提供全面支持。一旦 JAM 通过网络的链上治理机制批准为 Polkadot 技术，它将变得活跃。

A Catalyst for Adoption and Innovation

采用和创新的催化剂

The introduction of the JAM upgrade and the associated prize reflect Polkadot's unwavering commitment to increasing the protocol's use and adoption. The modular design and incentives for multiple client implementations are strategic steps towards decentralization, a fundamental principle guiding Polkadot's development.

JAM 升级的推出和相关奖励反映了 Polkadot 对增加协议的使用和采用的坚定承诺。模块化设计和对多个客户端实施的激励是去中心化的战略步骤，这是指导 Polkadot 发展的基本原则。

As JAM development progresses, the Polkadot ecosystem eagerly welcomes proposals from teams interested in implementing the upgrade in various programming environments, further expanding the protocol's reach and potential.

随着 JAM 开发的进展，Polkadot 生态系统热切欢迎有兴趣在各种编程环境中实施升级的团队提出建议，进一步扩大协议的影响范围和潜力。

Despite the recent announcement, DOT, the native token of the Polkadot network, has remained within a downtrend over the past month, currently trading at $6.75, marking a notable 24% decline from its previous level. However, the long-term prospects of the Polkadot project remain strong, fueled by its continued technological advancements and unwavering dedication to decentralization.

尽管最近宣布了这一消息，但 Polkadot 网络的原生代币 DOT 在过去一个月中仍处于下跌趋势，目前交易价格为 6.75 美元，较之前的水平大幅下跌 24%。然而，在持续的技术进步和对去中心化坚定不移的奉献的推动下，Polkadot 项目的长期前景仍然强劲。
