Offchain Labs 推出 Arbitrum BOLD，強化 Optimistic Rollup 爭議協議

Offchain Labs 在測試網上推出了 Arbitrum BOLD，這是 Arbitrum 鏈上樂觀匯總的爭議協議。 BOLD 是 Bounded Liquidity Delay 的縮寫，允許使用者成為驗證節點並參與共識。它可以防止惡意行為者故意破壞資料流的延遲攻擊。 BOLD 為以太坊上的 Arbitrum 狀態確認提供了固定的上限，使資源充足的一方能夠對抗對手，而無需捲入個人糾紛。

Offchain Labs Unveils Arbitrum BOLD, Strengthening Optimistic Rollup Dispute Protocol

Offchain Labs 推出 Arbitrum BOLD，加強 Optimistic Rollup 爭議協議

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 生態系統背後的驅動力，在測試網路上推出了 Arbitrum BOLD，這是一項突破性的爭議協議，旨在增強樂觀匯總的安全性和彈性。 BOLD 代表有界流動性延遲，提供了一種可以跨 Arbitrum 鏈部署的互動式詐欺證明機制。

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.

這種創新協議使用戶能夠操作驗證器節點，為網路的共識過程做出貢獻。此外，BOLD 還整合了針對延遲攻擊的強大防禦功能，延遲攻擊是一種普遍的網路安全威脅，惡意行為者會故意阻礙資料流以破壞系統功能。

"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 在最近的聲明中宣稱：“Arbitrum BOLD 提供了堅定不移的保證，確保以太坊區塊鏈上 Arbitrum 狀態的確認時間有固定的上限。” “它使一個孤立的、裝備精良的實體能夠抵禦多個對手的指控，消除了一對一對抗的需要。”

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 之前報導的那樣，Arbitrum 已成為著名的以太坊第 2 層網絡，擁有透過活躍錢包衡量的龐大用戶群。 2021 年 8 月，Offchain Labs 獲得 1.2 億美元融資，由 Lightspeed Venture Partners 領投。

Rationale for Arbitrum BOLD

BOLD 決定的理由

"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 時解釋道：「目前，透過詐欺證明對 Arbitrum One 和 Nova 進行驗證是被允許的，因為它們的爭議協議容易受到拒絕服務攻擊。」阻礙斷言確認，有效地無限期地延長從第2 層到第1 層的提款。

"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."

該公司解釋道：“我們設計了一種創新的驗證方法，引入了僅 7 天的額外確認延遲的固定上限，同時消除了延遲攻擊的可能性。” 「我們的BOLD 協議使Arbitrum 鏈驗證安全地無需許可，從而顯著推動它們走向更加去中心化的狀態。這一進步使唯一、誠實的驗證者能夠在以太坊區塊鏈上針對任意數量的惡意在行為者的爭議中取得勝利。

Benefits of Arbitrum BOLD

Arbitrum BOLD 的好處

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

Arbitrum BOLD 為 Arbitrum 生態系統提供了多方面的優勢：

• 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.

增強安全性：BOLD 加強了樂觀匯總的安全性，防止延遲攻擊並確保交易的及時確認。 ，促進去中心化。性，使其能夠處理更大的交易量。承諾。隨著測試的進展，社群熱切期待 BOLD 在 Arbitrum 主網上全面推出，開啟網路創新和成長的新時代。
