Offchain Labs 推出 Arbitrum BOLD，强化 Optimistic Rollup 争议协议

Offchain Labs 在测试网上推出了 Arbitrum BOLD，这是 Arbitrum 链上乐观汇总的争议协议。 BOLD 是 Bounded Liquidity Delay 的缩写，允许用户成为验证节点并参与共识。它可以防止恶意行为者故意破坏数据流的延迟攻击。 BOLD 为以太坊上的 Arbitrum 状态确认提供了固定的上限，使资源充足的一方能够对抗对手，而无需卷入个人纠纷。

Offchain Labs Unveils Arbitrum BOLD, Strengthening Optimistic Rollup Dispute Protocol

Offchain Labs 推出 Arbitrum BOLD，加强 Optimistic Rollup 争议协议

Offchain Labs, the driving force behind the Arbitrum ecosystem, has introduced Arbitrum BOLD on testnet, a groundbreaking dispute protocol designed to enhance the security and resilience of optimistic rollups. BOLD, standing for Bounded Liquidity Delay, provides an interactive fraud proof mechanism that can be deployed across Arbitrum chains.

Offchain Labs 是 Arbitrum 生态系统背后的驱动力，在测试网上推出了 Arbitrum BOLD，这是一种突破性的争议协议，旨在增强乐观汇总的安全性和弹性。 BOLD 代表有界流动性延迟，提供了一种可以跨 Arbitrum 链部署的交互式欺诈证明机制。

This innovative protocol empowers users to operate validator nodes, contributing to the network's consensus process. Moreover, BOLD incorporates robust defenses against delay attacks, a prevalent cybersecurity threat where malicious actors intentionally obstruct data flow to disrupt system functionality.

这种创新协议使用户能够操作验证器节点，为网络的共识过程做出贡献。此外，BOLD 还集成了针对延迟攻击的强大防御功能，延迟攻击是一种普遍的网络安全威胁，恶意行为者会故意阻碍数据流以破坏系统功能。

"Arbitrum BOLD offers an unwavering guarantee, ensuring a fixed upper limit on the confirmation time of Arbitrum states on the Ethereum blockchain," Offchain Labs declared in a recent statement. "It empowers a solitary, well-equipped entity to fend off accusations from multiple adversaries, eliminating the need for one-on-one confrontations."

Offchain Labs 在最近的一份声明中宣称：“Arbitrum BOLD 提供了坚定不移的保证，确保以太坊区块链上 Arbitrum 状态的确认时间有固定的上限。” “它使一个孤立的、装备精良的实体能够抵御多个对手的指控，消除了一对一对抗的需要。”

Arbitrum has emerged as a prominent Ethereum Layer 2 network, boasting a significant user base measured by active wallets, as previously reported by The Block. In August 2021, Offchain Labs secured $120 million in funding, with Lightspeed Venture Partners leading the investment round.

正如 The Block 之前报道的那样，Arbitrum 已成为著名的以太坊第 2 层网络，拥有通过活跃钱包衡量的庞大用户群。 2021 年 8 月，Offchain Labs 获得 1.2 亿美元融资，由 Lightspeed Venture Partners 领投。

Rationale for Arbitrum BOLD

BOLD 决定的理由

"At present, validation on Arbitrum One and Nova through fraud proofs is permissioned due to the vulnerability of their dispute protocols to denial-of-service attacks," explained Offchain Labs upon introducing BOLD in August 2023. "A malicious validator can repeatedly expend funds to hinder assertion confirmation, effectively prolonging withdrawals from Layer 2 to Layer 1 for an indefinite period."

Offchain Labs 在 2023 年 8 月推出 BOLD 时解释道：“目前，通过欺诈证明对 Arbitrum One 和 Nova 进行验证是被允许的，因为它们的争议协议容易受到拒绝服务攻击。”阻碍断言确认，有效地无限期地延长从第 2 层到第 1 层的提款。”

"We have devised an innovative approach to validation, introducing a fixed upper bound of just seven days of additional confirmation delay while eliminating susceptibility to delay attacks," the company elaborated. "Our BOLD protocol renders Arbitrum chain validation safely permissionless, propelling them significantly toward a more decentralized state. This advancement enables a sole, honest validator to emerge victorious in disputes on the Ethereum blockchain against any number of malicious actors."

该公司解释道：“我们设计了一种创新的验证方法，引入了仅 7 天的额外确认延迟的固定上限，同时消除了延迟攻击的可能性。” “我们的 BOLD 协议使 Arbitrum 链验证安全地无需许可，从而显着推动它们走向更加去中心化的状态。这一进步使唯一、诚实的验证者能够在以太坊区块链上针对任意数量的恶意行为者的争议中取得胜利。”

Benefits of Arbitrum BOLD

Arbitrum BOLD 的好处

Arbitrum BOLD offers a multifaceted array of benefits to the Arbitrum ecosystem:

Arbitrum BOLD 为 Arbitrum 生态系统提供了多方面的优势：

• Enhanced Security: BOLD strengthens the security of optimistic rollups, protecting against delay attacks and ensuring the timely confirmation of transactions.
• Increased Decentralization: By making validation permissionless, BOLD empowers a wider range of participants to contribute to the network's consensus process, promoting decentralization.
• Reduced Transaction Costs: BOLD's efficiency in dispute resolution can potentially result in lower transaction costs for users.
• Improved Scalability: The increased security and decentralization provided by BOLD can contribute to the scalability of the Arbitrum ecosystem, enabling it to handle a higher volume of transactions.

The launch of Arbitrum BOLD on testnet marks a significant milestone in the development of the Arbitrum ecosystem, bringing it closer to delivering on its promise of secure, scalable, and decentralized blockchain solutions. As testing progresses, the community eagerly anticipates the full rollout of BOLD on the Arbitrum mainnet, ushering in a new era of innovation and growth for the network.

增强安全性：BOLD 加强了乐观汇总的安全性，防止延迟攻击并确保交易的及时确认。 增强去中心化：通过无需许可的验证，BOLD 使更广泛的参与者能够为网络的共识过程做出贡献，促进去中心化。交易成本：BOLD 在争议解决方面的效率可能会降低用户的交易成本。 提高可扩展性：BOLD 提供的增强的安全性和去中心化有助于提高 Arbitrum 生态系统的可扩展性，使其能够处理更大的交易量。 Arbitrum BOLD 在测试网上的推出标志着 Arbitrum 生态系统发展的一个重要里程碑，使其更接近兑现其安全、可扩展和去中心化区块链解决方案的承诺。随着测试的进展，社区热切期待 BOLD 在 Arbitrum 主网上全面推出，开启网络创新和增长的新时代。
