BNB Chain推出opBNB，一种因乐观而增强的乐观汇总

BNB Chain 推出了 opBNB，这是一个基于 Optimism OP Stack 的第 2 层汇总，可在 BNB Chain 生态系统上实现更快、更便宜的交易。 opBNB 于 6 月 19 日推出，旨在通过每秒处理超过 4,000 笔交易，平均费用低于 0.5 美分，来缓解拥堵并降低交易成本。通过利用 Optimistic Rollups，opBNB 提高了数据可用性、批量交易并引入 100M Gas 限制，同时简化了从以太坊的以太坊虚拟机 (EVM) 代码迁移。

BNB Chain Unveils opBNB, an Optimistic Layer 2 Rollup

BNB 链推出 opBNB，一个乐观的第 2 层汇总

Introduction

介绍

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 是币安开发的与以太坊兼容的第 1 层区块链，宣布推出 opBNB，这是由 Optimism 的 OP Stack 提供支持的第 2 层汇总。这一重大发展旨在增强 BNB 链生态系统的可扩展性和成本效益。

Testnet Launch and Feedback Request

测试网启动和反馈请求

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 测试网于 2023 年 6 月 19 日上线。BNB Chain 团队积极寻求验证者和 dApp 开发者的反馈，以优化网络性能和用户体验。

Benefits and Features

优点和特点

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

opBNB 为 BNB 链生态系统引入了一系列进步，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

交易能力提高：opBNB 拥有每秒处理超过 4,000 笔交易（TPS）的能力，缓解拥堵并改善用户体验。 交易费用降低：平均交易费用不到半美分，与第 1 层交易。提高数据可用性：opBNB 确保交易数据随时可供用户使用，减少瓶颈和延迟的可能性。批量交易：opBNB 将多个交易合并为单个批次，进一步增强交易吞吐量并降低 Gas 成本。100M Gas 限制：opBNB 引入了 1 亿的更高 Gas 限制，可以执行更复杂的智能合约，而不会遇到 Gas 耗尽错误。 简化 EVM 迁移：opBNB 简化了将以太坊虚拟机 (EVM) 代码从以太坊迁移到 BNB 链的过程，促进dApps 的跨链部署。在 Layer 2 领域的竞争定位

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采用Layer 2解决方案是其在快速发展的Layer 2生态系统中增强竞争力的战略举措。虽然在 2021 年牛市期间，BNB Chain 和 Solana 等 Layer 1 区块链最初与以太坊相比具有低成本优势，但 Optimism 和 Arbitrum 等领先的 Layer 2 解决方案现在提供更低的平均交易费用。

Optimism's Bedrock Upgrade

乐观主义的基石升级

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，该堆栈是在 2023 年 6 月 6 日作为 Bedrock 升级的一部分引入的。OP Stack 模块化了 Optimism 的技术堆栈，使第三方开发人员能够基于其代码构建自定义第 2 层解决方案。

Fraud Proof Mechanism

防欺诈机制

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 原生的乐观欺诈证明。这种方法假设交易有效，但对提款施加 7 天的延迟，以便检测恶意交易。提交虚假转换的验证者将受到抵押资产削减的惩罚。

BNB Token Performance

BNB 代币表现

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

尽管推出了 opBNB，但区块链的原生 BNB 代币在过去 24 小时内仍保持相对稳定。

Conclusion

结论

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标志着网络演进迈出了重要一步。通过采用Layer 2解决方案，BNB Chain旨在解决可扩展性和成本问题，增强其在Layer 2生态系统中的竞争力，并为dApp开发者和用户提供更加用户友好和更具成本效益的平台。
