Arbitrum 推出防欺诈测试网，引领以太坊第 2 层去中心化

Arbitrum 是领先的以太坊 Layer-2 扩展解决方案，已将其无需许可的欺诈证明、有界流动性延迟 (BOLD) 部署到测试网。 BOLD 旨在通过允许社区验证以太坊提款并维护网络安全来增强去中心化，这标志着向完全去中心化的 Arbitrum 生态系统迈出了重要一步。

Arbitrum Spearheads Decentralization with Launch of Fraud Proof Testnet

Arbitrum 通过推出防欺诈测试网引领去中心化

In a significant step towards decentralization, Arbitrum, the leading Ethereum layer-2 scaling solution by total value locked (TVL), has announced the deployment of its permissionless fraud proof, Bounded Liquidity Delay (BOLD), to testnet. The announcement was made on April 16th by Offchain Labs, the developers of Arbitrum.

领先的以太坊第 2 层扩容解决方案 Arbitrum（按总价值锁定 (TVL) 计算）已宣布在测试网上部署其无需许可的欺诈证明、有界流动性延迟 (BOLD)，这是迈向去中心化的重要一步。 Arbitrum 的开发商 Offchain Labs 于 4 月 16 日宣布了这一消息。

Ethereum Layer-2: A Burgeoning Sector

以太坊 Layer-2：一个新兴领域

Ethereum layer-2 solutions have gained prominence in recent years, as they offer low-cost transaction options and increased scalability. As of April 17th, data from L2Beat indicates that these platforms control over $37 billion worth of assets. Popular layer-2 platforms include Arbitrum, Optimism, Base, and others.

以太坊第 2 层解决方案近年来备受关注，因为它们提供了低成本的交易选项和更高的可扩展性。截至4月17日，L2Beat的数据显示，这些平台控制着价值超过370亿美元的资产。流行的第 2 层平台包括 Arbitrum、Optimism、Base 等。

Challenges of Layer-2 Solutions

第 2 层解决方案的挑战

Despite their popularity, layer-2 platforms face challenges. Most notably, the development of their fraud proofs is still ongoing. This contrasts with common user transactions on traditional blockchains, where each transaction is thoroughly validated through a consensus mechanism involving miners or validators.

尽管第二层平台很受欢迎，但仍面临挑战。最值得注意的是，他们的欺诈证明的开发仍在进行中。这与传统区块链上的普通用户交易形成鲜明对比，传统区块链上的每笔交易都通过涉及矿工或验证者的共识机制进行彻底验证。

Layer-2 platforms differ by processing transactions off-chain, making it theoretically impossible to verify their legitimacy before final confirmation on the main chain.

Layer-2 平台的不同之处在于，它在链外处理交易，因此理论上不可能在主链上最终确认之前验证其合法性。

Fraud Proofs: A Critical Solution

欺诈证明：关键解决方案

Fraud proofs, such as those pioneered by Arbitrum and other optimistic roll-up solutions, address this challenge. These proofs ensure the validity of off-chain transactions, acting as a safety net for the integrity of these transactions while promoting efficient off-chain processing.

欺诈证明，例如 Arbitrum 和其他乐观汇总解决方案首创的欺诈证明，可以解决这一挑战。这些证明确保了链下交易的有效性，充当这些交易完整性的安全网，同时促进高效的链下处理。

BOLD's Decentralized Architecture

BOLD 的去中心化架构

In line with fundamental blockchain principles, BOLD is designed to be decentralized. The community will operate nodes, replacing the current centralized transaction verification process handled by a small group of validators.

根据区块链的基本原则，BOLD 的设计是去中心化的。社区将运营节点，取代当前由一小群验证者处理的集中式交易验证过程。

BOLD's testnet deployment signals Arbitrum's commitment to opening its secure transaction channels to public participation, fostering network security, and validating Ethereum withdrawals. This pioneering step is expected to contribute to a decentralized ecosystem while strengthening the Arbitrum platform.

BOLD 的测试网部署标志着 Arbitrum 致力于向公众开放其安全交易渠道、促进网络安全并验证以太坊提款。这一开创性的举措预计将有助于构建去中心化的生态系统，同时加强 Arbitrum 平台。

Industry Impact and ARB's Price

行业影响和ARB的价格

Arbitrum's move marks a significant milestone, making it the first Ethereum layer-2 to launch fraud proofs in testnet. The announcement has also prompted Ryan Watts of Optimism to unveil plans to create a decentralized fraud-proof system for the second-largest layer-2 by TVL.

Arbitrum 的举动标志着一个重要的里程碑，使其成为第一个在测试网络中推出欺诈证明的以太坊第 2 层。这一公告还促使 Optimism 的 Ryan Watts 公布了为 TVL 第二大 Layer-2 创建去中心化防欺诈系统的计划。

Despite these advancements, ARB's price has remained relatively stable but faces selling pressure. The token has depreciated by 50% from its March 2022 highs, but if buyers reverse the selling trend, it could potentially rebound towards $1.5.

尽管取得了这些进展，ARB 的价格仍保持相对稳定，但面临抛售压力。该代币已较 2022 年 3 月高点贬值 50%，但如果买家扭转抛售趋势，其可能反弹至 1.5 美元。
