Coinbase 推出 Base，一個用於以太坊可擴展性的第 2 層區塊鏈

美國最大的加密貨幣交易所 Coinbase 正在推出 Base，這是一個以太坊第 2 層區塊鏈，旨在為用戶提供更快、更具成本效益的交易。此舉使 Coinbase 與 Arbitrum 和其他計劃在今年稍後推出類似產品的公司直接競爭。 Base 目前可供開發人員測試，利用 Optimism 的 OP Stack 程式碼庫，並將與 Optimism 生態系統合作以促進創新和互通性。

Coinbase Unveils Base, a Layer 2 Blockchain for Ethereum Scalability

Coinbase 推出 Base，一個用於以太坊可擴展性的第 2 層區塊鏈

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.

美國領先的加密貨幣交易所 Coinbase 宣布開發名為 Base 的新第 2 層區塊鏈，旨在為用戶提供以太坊網路上增強的交易功能，這是一項重大舉措。

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 層區塊鏈（通常稱為匯總）透過在將用戶交易整合到以太坊區塊鏈之前對用戶交易進行批次和壓縮來進行操作。這項策略讓用戶可以利用以太坊強大的安全基礎設施，同時規避其臭名昭著的高額交易費用和緩慢的執行時間。

Crucial Role of Rollups

匯總的重要作用

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.

人們普遍預計 Rollup 將在擴展以太坊方面發揮關鍵作用，這是適應數十億用戶湧入並可能取代銀行等傳統機構所必需的基本面向。 Coinbase 協議主管 Jesse Pollak 表示，Coinbase 的匯總 Base 目前可供應用程式開發人員測試，預計主網將在第三季末之前推出。

Competitive Landscape

競爭格局

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 並不是第一家涉足區塊鏈開發的加密貨幣交易所，幣安在 2020 年 9 月推出了 BNB 智慧鏈。然而，作為第一家建立 Rollup 的交易所，它標誌著一個重要的里程碑。

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 領域競爭非常激烈，Arbitrum 和 Optimism 等領導企業都擁有可觀的估值。 Arbitrum 最近處理的交易量超過了以太坊，這是首次進行匯總，凸顯了其日益增長的重要性。

Zero-Knowledge Rollups

零知識匯總

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.

今年晚些時候，市場預計將出現多個利用零知識 (ZK) 技術的 Rollup。專家們稱讚 ZK 加密技術是擴展以太坊的一種有前途的途徑，因為它在速度和安全性方面有可能超越現有的第 2 層區塊鏈。

Validity Proof

有效性證明

"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「樂觀」總結假定交易的有效性，提供 7 天的爭議窗口。相比之下，ZK rollups 會產生“有效性證明”，即驗證已處理交易的可驗證收據，從而消除了確認延遲的需要。

Coinbase's Base

Coinbase 的基礎

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 將透過利用 Optimism 的程式碼庫「OP Stack」來採用經過驗證的方法。 OP 堆疊的模組化允許整合未來的技術進步，例如 ZK 技術，確保可升級性。

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 打算積極為 OP Stack 做出貢獻，並透過 Optimism 營運的資助計畫來支持開發公共產品的開發人員，該計畫由一定比例的基本交易費資助。

Collaboration and Interoperability

協作和互通性

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

隨著時間的推移，Base 和 Optimism 的目標是無縫合併，創建一個統一的「超級鏈」以及互連鍊網路。

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 致力於將自己定位為以開發人員為中心的匯總，並認識到應用程式開發在促進加密生態系統內實用性方面的關鍵作用。

Grants Program

資助計劃

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.

為了鼓勵 Base 的發展，Coinbase 及其創投部門為軟體工程師設立了一項資助計畫。該計劃將為在 Base 平台上建立有價值的應用程式的開發人員提供財務支持，從而培育一個充滿活力的生態系統。

Major DeFi Projects

主要 DeFi 項目

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，幾個主要的DeFi項目已經在與Base集成，包括Aave、Ribbon和Balancer。

Conclusion

結論

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 代表著快節奏的區塊鏈發展領域的策略性舉措。 Base 利用 OP Stack 並專注於開發人員採用，旨在為用戶提供以太坊上的優化體驗，增強可擴展性並降低交易成本。隨著 Rollup 生態系統的不斷發展，Base 將面臨來自老牌參與者和基於 ZK 的創新解決方案的激烈競爭。然而，Coinbase 的聲譽和廣泛的用戶基礎使其能夠很好地佔領 Layer 2 市場的重要份額，並為以太坊的更廣泛擴展做出貢獻。
