Coinbase 推出 Base，一个用于以太坊可扩展性的第 2 层区块链

美国最大的加密货币交易所 Coinbase 正在推出 Base，这是一个以太坊第 2 层区块链，旨在为用户提供更快、更具成本效益的交易。此举使 Coinbase 与 Arbitrum 和其他计划在今年晚些时候推出类似产品的公司展开直接竞争。 Base 目前可供开发人员测试，利用 Optimism 的 OP Stack 代码库，并将与 Optimism 生态系统合作以促进创新和互操作性。

Coinbase Unveils Base, a Layer 2 Blockchain for Ethereum Scalability

Coinbase 推出 Base，一个用于以太坊可扩展性的第 2 层区块链

In a significant move, Coinbase, the leading cryptocurrency exchange in the United States, has announced the development of a new Layer 2 blockchain named Base, aimed at providing its users with enhanced transaction capabilities on the Ethereum network.

美国领先的加密货币交易所 Coinbase 宣布开发名为 Base 的新第 2 层区块链，旨在为用户提供以太坊网络上增强的交易功能，这是一项重大举措。

Layer 2 blockchains, often referred to as rollups, operate by batching and compressing user transactions before integrating them into the Ethereum blockchain. This strategy allows users to leverage Ethereum's robust security infrastructure while circumventing its notoriously high transaction fees and sluggish execution times.

第 2 层区块链（通常称为汇总）通过在将用户交易集成到以太坊区块链之前对用户交易进行批处理和压缩来进行操作。这一策略允许用户利用以太坊强大的安全基础设施，同时规避其臭名昭著的高额交易费用和缓慢的执行时间。

Crucial Role of Rollups

汇总的重要作用

Rollups are widely anticipated to play a pivotal role in scaling Ethereum, a fundamental aspect necessary to accommodate the influx of billions of users and potentially replace legacy institutions like banks. Coinbase's rollup, Base, is currently available for testing by application developers, with a mainnet launch expected before the end of the third quarter, according to Jesse Pollak, head of protocols at Coinbase.

人们普遍预计 Rollup 将在扩展以太坊方面发挥关键作用，这是适应数十亿用户涌入并可能取代银行等传统机构所必需的基本方面。 Coinbase 协议主管 Jesse Pollak 表示，Coinbase 的汇总 Base 目前可供应用程序开发人员测试，预计主网将在第三季度末之前推出。

Competitive Landscape

竞争格局

Coinbase is not the first cryptocurrency exchange to venture into blockchain development, with Binance launching its BNB Smart Chain in September 2020. However, it marks a significant milestone as the first exchange to build a rollup.

Coinbase 并不是第一家涉足区块链开发的加密货币交易所，币安于 2020 年 9 月推出了 BNB 智能链。然而，作为第一家建立 Rollup 的交易所，它标志着一个重要的里程碑。

The field of rollups is highly competitive, with leading players such as Arbitrum and Optimism boasting substantial valuations. Arbitrum recently processed more transactions than Ethereum, a first for a rollup, highlighting its growing prominence.

Rollups 领域竞争非常激烈，Arbitrum 和 Optimism 等领先企业都拥有可观的估值。 Arbitrum 最近处理的交易量超过了以太坊，这是首次进行汇总，凸显了其日益增长的重要性。

Zero-Knowledge Rollups

零知识汇总

Later this year, the market can expect the debut of several rollups utilizing zero-knowledge (ZK) technology. Experts hail ZK cryptography as a promising avenue for scaling Ethereum due to its potential to surpass existing Layer 2 blockchains in terms of speed and security.

今年晚些时候，市场预计将出现多个利用零知识 (ZK) 技术的 Rollup。专家们称赞 ZK 加密技术是扩展以太坊的一种有前途的途径，因为它在速度和安全性方面有可能超越现有的第 2 层区块链。

Validity Proof

有效性证明

"Optimistic" rollups like Arbitrum and Optimism presume the validity of transactions, offering a seven-day dispute window. In contrast, ZK rollups generate a "validity proof," a verifiable receipt authenticating the processed transactions, eliminating the need for a confirmation delay.

Arbitrum 和 Optimism 等“乐观”汇总假定交易的有效性，提供 7 天的争议窗口。相比之下，ZK rollups 会生成“有效性证明”，即验证已处理交易的可验证收据，从而消除了确认延迟的需要。

Coinbase's Base

Coinbase 的基础

Base will adopt a proven approach by leveraging Optimism's codebase, the "OP Stack." The modularity of the OP Stack allows for the integration of future technological advancements, such as ZK technologies, ensuring upgradeability.

Base 将通过利用 Optimism 的代码库“OP Stack”来采用经过验证的方法。 OP 堆栈的模块化允许集成未来的技术进步，例如 ZK 技术，确保可升级性。

Moreover, Coinbase intends to actively contribute to the OP Stack and support developers working on public goods through an Optimism-run grant program, funded by a percentage of Base transaction fees.

此外，Coinbase 打算积极为 OP Stack 做出贡献，并通过 Optimism 运营的资助计划支持开发公共产品的开发人员，该计划由一定比例的基本交易费资助。

Collaboration and Interoperability

协作和互操作性

Over time, Base and Optimism aim to seamlessly merge, creating a unified "super-chain" alongside a network of interconnected chains.

随着时间的推移，Base 和 Optimism 的目标是无缝合并，创建一个统一的“超级链”以及互连链网络。

In addition, Base seeks to differentiate itself as a developer-centric rollup, recognizing the crucial role of application development in fostering utility within the crypto ecosystem.

此外，Base 致力于将自己定位为以开发人员为中心的汇总，认识到应用程序开发在促进加密生态系统内实用性方面的关键作用。

Grants Program

资助计划

To encourage development on Base, Coinbase and its venture arm have established a grants program for software engineers. This program will provide financial support to developers building valuable applications on the Base platform, fostering a vibrant ecosystem.

为了鼓励 Base 的发展，Coinbase 及其风险投资部门为软件工程师设立了一项资助计划。该计划将为在 Base 平台上构建有价值的应用程序的开发人员提供财务支持，从而培育一个充满活力的生态系统。

Major DeFi Projects

主要 DeFi 项目

Coinbase has revealed that several major DeFi projects are already in the process of integrating with Base, including Aave, Ribbon, and Balancer.

Coinbase透露，几个主要的DeFi项目已经在与Base集成，包括Aave、Ribbon和Balancer。

Conclusion

结论

Coinbase's launch of Base represents a strategic move in the fast-paced world of blockchain development. Leveraging the OP Stack and focusing on developer adoption, Base aims to provide users with an optimized experience on Ethereum, enhancing scalability and reducing transaction costs. As the rollup ecosystem continues to evolve, Base will face stiff competition from established players and innovative ZK-based solutions. However, Coinbase's reputation and extensive user base position it well to capture a significant share of the Layer 2 market and contribute to the broader scaling of Ethereum.

Coinbase 推出 Base 代表着快节奏的区块链发展领域的一项战略举措。 Base 利用 OP Stack 并专注于开发人员采用，旨在为用户提供以太坊上的优化体验，增强可扩展性并降低交易成本。随着 Rollup 生态系统的不断发展，Base 将面临来自老牌参与者和基于 ZK 的创新解决方案的激烈竞争。然而，Coinbase 的声誉和广泛的用户基础使其能够很好地占领 Layer 2 市场的重要份额，并为以太坊的更广泛扩展做出贡献。
