BNB Chain推出opBNB，一種因樂觀而增強的樂觀總結

BNB Chain 推出了 opBNB，這是一個基於 Optimism OP Stack 的第 2 層匯總，可在 BNB Chain 生態系統上實現更快、更便宜的交易。 opBNB 於 6 月 19 日推出，旨在透過每秒處理超過 4,000 筆交易，平均費用低於 0.5 美分，來緩解擁塞並降低交易成本。透過利用 Optimistic Rollups，opBNB 提高了資料可用性、大量交易並引入 100M Gas 限制，同時簡化了從以太坊的以太坊虛擬機器 (EVM) 程式碼遷移。

BNB Chain Unveils opBNB, an Optimistic Layer 2 Rollup

BNB 鏈推出 opBNB，一個樂觀的第 2 層匯總

Introduction

介紹

BNB Chain, the Ethereum-compatible Layer 1 blockchain developed by Binance, has announced the launch of opBNB, a Layer 2 rollup powered by Optimism's OP Stack. This significant development aims to enhance the scalability and cost-effectiveness of the BNB Chain ecosystem.

BNB Chain 是幣安開發的與以太坊相容的第 1 層區塊鏈，宣布推出 opBNB，這是由 Optimism 的 OP Stack 提供支援的第 2 層匯總。這項重大發展旨在增強 BNB 鏈生態系統的可擴展性和成本效益。

Testnet Launch and Feedback Request

測試網啟動和回饋請求

opBNB's testnet went live on June 19, 2023. The BNB Chain team actively seeks feedback from validators and dApp developers to optimize the network's performance and user experience.

opBNB 測試網於 2023 年 6 月 19 日上線。

Benefits and Features

優點和特點

opBNB introduces a range of advancements to the BNB Chain ecosystem, including:

opBNB 為 BNB 鏈生態系統引入了一系列進步，包括：

• Increased Transaction Capacity: opBNB boasts the ability to process over 4,000 transactions per second (TPS), alleviating congestion and improving the user experience.
• Reduced Transaction Fees: With an average transaction fee of less than half a cent, opBNB offers significant cost savings compared to Layer 1 transactions.
• Improved Data Availability: opBNB ensures that transaction data is readily available to users, reducing the potential for bottlenecks and delays.
• Batched Transactions: opBNB combines multiple transactions into single batches, further enhancing transaction throughput and reducing gas costs.
• 100M Gas Limit: opBNB introduces a higher gas limit of 100 million, enabling more complex smart contract executions without encountering out-of-gas errors.
• Simplified EVM Migration: opBNB simplifies the process of migrating Ethereum Virtual Machine (EVM) code from Ethereum to BNB Chain, facilitating the cross-chain deployment of dApps.

Competitive Positioning in the Layer 2 Landscape

交易能力提升：opBNB 擁有每秒處理超過 4,000 筆交易（TPS）的能力，緩解擁擠並改善使用者體驗。確保交易資料隨時可供用戶使用，減少瓶頸和延遲的可能性。的更高Gas 限制，可以執行更複雜的智能合約，而不會遇到Gas 耗盡錯誤。促進dApps 的跨鏈部署。

BNB Chain's adoption of Layer 2 solutions is a strategic move to enhance its competitiveness in the rapidly growing Layer 2 ecosystem. While Layer 1 blockchains like BNB Chain and Solana initially offered a low-cost advantage compared to Ethereum during the 2021 bull market, leading Layer 2 solutions such as Optimism and Arbitrum now offer lower average transaction fees.

BNB Chain採用Layer 2解決方案是其在快速發展的Layer 2生態系統中增強競爭力的策略性舉措。雖然在 2021 年牛市期間，BNB Chain 和 Solana 等 Layer 1 區塊鏈最初與以太坊相比具有低成本優勢，但 Optimism 和 Arbitrum 等領先的 Layer 2 解決方案現在提供更低的平均交易費用。

Optimism's Bedrock Upgrade

樂觀主義的基石升級

opBNB leverages Optimism's OP Stack, which was introduced as part of the Bedrock upgrade on June 6, 2023. OP Stack modularizes Optimism's technology stack, enabling third-party developers to build custom Layer 2 solutions based on its code.

opBNB 利用Optimism 的OP Stack，該堆疊是在2023 年6 月6 日作為Bedrock 升級的一部分引入的。解決方案。

Fraud Proof Mechanism

防詐騙機制

opBNB utilizes the optimistic fraud proofs native to Optimism. This approach assumes that transactions are valid but imposes a seven-day delay on withdrawals to allow for the detection of malicious transactions. Validators who submit false transitions are penalized by having their collateral assets slashed.

opBNB 利用 Optimism 原生的樂觀詐欺證明。這種方法假設交易有效，但對提款施加 7 天的延遲，以便檢測惡意交易。提交虛假轉換的驗證者將受到抵押資產削減的懲罰。

BNB Token Performance

BNB 代幣表現

Despite the launch of opBNB, the blockchain's native BNB token has remained relatively stable over the past 24 hours.

儘管推出了 opBNB，但區塊鏈的原生 BNB 代幣在過去 24 小時內仍保持相對穩定。

Conclusion

結論

BNB Chain's launch of opBNB marks a significant step forward in the network's evolution. By embracing Layer 2 solutions, BNB Chain aims to address scalability and cost concerns, enhance its competitiveness in the Layer 2 ecosystem, and provide a more user-friendly and cost-effective platform for dApp developers and users.

BNB Chain推出opBNB標誌著網路演進邁出了重要一步。透過採用Layer 2解決方案，BNB Chain旨在解決可擴展性和成本問題，增強其在Layer 2生態系統中的競爭力，並為dApp開發者和用戶提供更用戶友好和更具成本效益的平台。
