Coinbase 發動閃電革命，改變比特幣交易

美國領先的加密貨幣交易所 Coinbase 推出了對閃電網路的支持，為用戶提供一種高效且經濟實惠的比特幣發送、接收和支付方式。先前，Coinbase 轉帳發生在鏈上，導致網路活動高峰期間出現交易延遲和高額費用。閃電網路於 2017 年推出，是建立在比特幣區塊鏈上的第 2 層協議，可促進高速、低成本的鏈下交易。透過與 Lightspark 合作，Coinbase 旨在徹底改變其閃電網路集成，使用戶能夠輕鬆且經濟高效地在全球範圍內轉移比特幣，與其他支付方式相比，費用顯著降低。

Coinbase Unveils Lightning Network Integration, Revolutionizing Bitcoin Transactions

Coinbase 推出閃電網路集成，徹底改變比特幣交易

San Francisco, California - [Date] - Coinbase, the United States' preeminent cryptocurrency exchange in terms of trading volume, heralds a transformative era for its users with the official launch of Lightning Network support. This groundbreaking protocol will empower individuals to conduct bitcoin transactions directly from their Coinbase accounts with unparalleled speed and efficiency.

加州舊金山 - [日期] - 美國交易量卓越的加密貨幣交易所 Coinbase 正式推出閃電網路支持，為其用戶預示著一個變革時代的到來。這項突破性的協議將使個人能夠以無與倫比的速度和效率直接從他們的 Coinbase 帳戶進行比特幣交易。

Historically, bitcoin transfers on Coinbase were processed via the primary blockchain, resulting in transaction durations ranging from 10 minutes to two hours. Moreover, during periods of network congestion, exorbitant fees were incurred.

從歷史上看，Coinbase 上的比特幣轉帳是透過主區塊鏈處理的，導致交易持續時間從 10 分鐘到兩個小時不等。此外，在網路擁塞期間，還會產生高昂的費用。

Introduced in 2017, the Lightning Network emerges as a Layer 2 protocol built upon the Bitcoin blockchain. Its primary objective is to mitigate scalability challenges by establishing bidirectional payment channels. These channels facilitate near-instantaneous, low-cost transactions off-chain without immediate settlement on the base layer.

閃電網路於 2017 年推出，作為建立在比特幣區塊鏈之上的第 2 層協議而出現。其主要目標是透過建立雙向支付管道來緩解可擴展性挑戰。這些管道促進了近乎即時、低成本的鏈下交易，無需立即在基礎層進行結算。

"As Bitcoin adoption gains momentum, economic freedom expands globally," remarked Viktor Bunin, Coinbase's protocol specialist and Lightning integration lead, in an exclusive interview with The Block. "Our Lightning integration is now live, rendering Bitcoin more accessible and practical worldwide. By partnering with Lightspark, we are offering expedited and cost-effective BTC payments, marking a pivotal milestone for the ecosystem."

Coinbase 協議專家兼閃電網路整合負責人 Viktor Bunin 在接受 The Block 獨家採訪時表示：“隨著比特幣採用勢頭強勁，經濟自由度在全球範圍內擴大。” “我們的閃電網路整合現已上線，使比特幣在全球範圍內更容易訪問和實用。透過與 Lightspark 合作，我們提供快速且經濟高效的 BTC 支付，這標誌著生態系統的關鍵里程碑。”

Fees on the Lightning Network comprise a nominal flat rate base fee as low as one satoshi (the smallest unit of bitcoin, equivalent to less than $0.01) and a liquidity provider fee or fee rate calculated as a percentage of the transaction value. Node operators on the network possess the authority to set their fees at varying levels to compensate for safeguarding liquidity.

閃電網路的費用包括低至一聰（比特幣的最小單位，相當於不到 0.01 美元）的名義統一費率基本費用和按交易價值百分比計算的流動性提供者費用或費率。網路上的節點業者有權將費用設定在不同水平，以補償保障流動性。

Bunin disclosed to The Block a 0.1% processing fee associated with Lightning transactions on Coinbase, applicable exclusively to sends. These transactions should be processed within a few seconds. At launch, Coinbase users will encounter a maximum withdrawal limit of $2,000, translating to a maximum withdrawal fee of $2. While this limit exceeds the average Ethereum Layer 2 transaction fees, it remains below those of the Bitcoin blockchain.

Bunin 向 The Block 透露，與 Coinbase 上的閃電交易相關的 0.1% 的處理費僅適用於發送。這些交易應在幾秒鐘內處理完畢。推出時，Coinbase 用戶將面臨 2,000 美元的最高提款限額，即最高提款費用為 2 美元。雖然這個限制超過了以太坊第 2 層的平均交易費用，但它仍然低於比特幣區塊鏈的交易費用。

"We selected a conservative limit because, although Lightning supports arbitrarily large BTC sends, the average success rate of payments diminishes as the payment size increases," explained Bunin. "Imposing a lower limit at launch will enhance our users' experience and can be adjusted based on user feedback and as liquidity on the network expands."

「我們選擇了一個保守的限制，因為儘管閃電網路支援任意大的 BTC 發送，但隨著支付規模的增加，支付的平均成功率會降低，」Bunin 解釋道。 “在發佈時施加較低的限制將增強我們的用戶體驗，並且可以根據用戶反饋和網路流動性的擴大進行調整。”

In a statement shared with The Block, Coinbase asserted that its Lightning Network integration has slashed the cost of sending bitcoin globally for its users by a factor of 20 in comparison to the average 2% charged on credit card transactions and a fraction of the $30 incurred in wire transfers.

在與The Block 分享的聲明中，Coinbase 聲稱，其閃電網路整合已將用戶在全球範圍內發送比特幣的成本削減了20 倍，而信用卡交易的平均費用為2%，僅佔30 美元的一小部分。

While the integration will empower users in supported regions to select between Lightning or the Bitcoin base layer for withdrawals and payments, Coinbase has refrained from specifying the specific regions that will enjoy this support at launch. "The Lightning Network Integration is not yet available in all regions. We are rolling out support on a case-by-case basis," stated Bunin.

雖然整合將使受支援地區的用戶能夠在閃電網路或比特幣基礎層之間進行選擇以進行提款和支付，但 Coinbase 並未指定在發佈時將享受此支援的特定地區。 「閃電網路整合尚未在所有地區提供。我們正在根據具體情況提供支持，」Bunin 表示。

Collaboration with Lightspark

與Lightspark合作

Coinbase has forged a strategic partnership with Lightspark, a Lightning Network infrastructure firm, to facilitate this integration. Lightspark, led by CEO and co-founder David Marcus, boasts a distinguished legacy in the financial technology industry, including leadership roles at PayPal and Meta, where Marcus spearheaded the Diem stablecoin project.

Coinbase 已與閃電網路基礎設施公司 Lightspark 建立了策略合作夥伴關係，以促進這項整合。 Lightspark 由執行長兼聯合創始人 David Marcus 領導，在金融科技行業擁有傑出的遺產，包括在 PayPal 和 Meta 擔任領導職務，Marcus 在這兩家公司領導了 Diem 穩定幣專案。

The selection of Lightspark as Coinbase's integration partner was formally announced on April 3, with Marcus hailing it as another "significant milestone" for Lightning's trajectory.

4 月 3 日正式宣布選擇 Lightspark 作為 Coinbase 的整合合作夥伴，Marcus 稱讚這是閃電網路發展軌蹟的另一個「重要里程碑」。

"Our decision to engage a non-custodial integration partner stems from Lightning's design, which incorporates an optimization component with regard to channel liquidity management and route success rates," Bunin explained to The Block. "It made strategic sense to leverage the expertise of a partner singularly focused on resolving these issues, while Coinbase could prioritize securing our users' assets and enhancing their user experience while employing Lightning."

「我們決定聘請非託管整合合作夥伴源自於閃電網路的設計，其中包含了有關通路流動性管理和路線成功率的最佳化元件，」Bunin 向 The Block 解釋道。 “利用專注於解決這些問題的合作夥伴的專業知識具有戰略意義，而 Coinbase 可以在使用閃電網路的同時優先考慮保護用戶的資產並增強他們的用戶體驗。”

Commenting on today's rollout, Marcus expressed his enthusiasm for the collaboration with Coinbase: "Partnering with Coinbase to introduce Lightning payments to their customers is a pivotal milestone in our shared objective of delivering practical solutions for Internet payments. Collaborating closely with the Coinbase team has been an exceptional experience, and we are thrilled that hundreds of millions of individuals in hundreds of countries can now execute swift, economical Bitcoin transactions."

在評論今天的推出時，Marcus 表達了他對與 Coinbase 合作的熱情：「與 Coinbase 合作向客戶推出閃電支付是我們為網路支付提供實用解決方案的共同目標的關鍵里程碑。與 Coinbase 團隊的密切合作這是一次非凡的體驗，我們很高興數百個國家的數億人現在可以執行快速、經濟的比特幣交易。

No Plans for Coinbase Wallet Integration

沒有整合 Coinbase 錢包的計劃

Bunin confirmed that there are currently no plans to integrate Lightning into Coinbase Wallet (its non-custodial web3 wallet) or any other Coinbase products or services at this juncture. However, the team will diligently monitor the Lightning Network's growth and its adoption among Coinbase customers to inform potential expansion into products such as Coinbase Wallet or its crypto payments service Coinbase Commerce.

Bunin 證實，目前尚無計劃將閃電網路整合到 Coinbase 錢包（其非託管 web3 錢包）或任何其他 Coinbase 產品或服務中。然而，該團隊將努力監控閃電網路的成長及其在 Coinbase 客戶中的採用，以告知 Coinbase 錢包或其加密支付服務 Coinbase Commerce 等產品的潛在擴展。

"While we cannot predict the number of users who will utilize Lightning to transmit BTC, we are encouraged by the traction we have observed for Layer 2s in other ecosystems," continued Bunin. Citing Ethereum, he noted that approximately 35% of ETH sends were conducted via Layer 2 protocols such as Coinbase-incubated Base network. "Usage, adoption, and traction of Layer 2s on Bitcoin and Ethereum are fundamentally different, but we generally anticipate Layer 2 usage to increase over time as users seek cheaper and faster transactions."

Bunin 繼續說道：“雖然我們無法預測將使用閃電網路傳輸 BTC 的用戶數量，但我們對其他生態系統中第 2 層的吸引力感到鼓舞。”他引用以太坊為例，指出大約 35% 的 ETH 發送是透過 Coinbase 孵化的 Base 網路等第 2 層協定進行的。 「比特幣和以太坊上第2 層的使用、採用和吸引力有著本質上的不同，但我們普遍預計，隨著用戶尋求更便宜、更快的交易，第2 層的使用量會隨著時間的推移而增加。

Genesis of the Integration

整合的起源

In April 2023, Coinbase CEO Brian Armstrong initially hinted at Coinbase's forthcoming support for the Lightning Network. Subsequently, in September 2023, Coinbase affirmed its intention to integrate the Bitcoin Layer 2, with Armstrong emphasizing that bitcoin is "the most critical asset in crypto" and that the exchange was "delighted to contribute our efforts to facilitating faster/cheaper Bitcoin transactions."

2023 年 4 月，Coinbase 執行長 Brian Armstrong 最初暗示 Coinbase 即將支持閃電網路。隨後，在2023 年9 月，Coinbase 確認了整合比特幣第2 層的意圖，阿姆斯特朗強調比特幣是“加密貨幣中最重要的資產”，並且該交易所“很高興為促進更快/更便宜的比特幣交易做出貢獻”。 ”

Armstrong's remarks culminated a consultation process initiated a month earlier, soliciting feedback on the optimal implementation of Lightning. This process commenced after Armstrong responded to a post from Block CEO Jack Dorsey inquiring, "Why do you perpetually disregard Bitcoin and Lightning? What 'crypto' constitutes a superior money transmission protocol, and why?"

阿姆斯壯的言論使一個月前啟動的諮詢流程達到了高潮，徵求有關閃電網路最佳實施的反饋意見。這個過程是在阿姆斯特朗回复Block 首席執行官傑克·多爾西(Jack Dorsey) 的帖子後開始的，他詢問道：“為什麼你永遠忽視比特幣和閃電網絡？什麼'加密貨幣'構成了一種優越的貨幣傳輸協議，為什麼？

"We are exploring the best approach to incorporate Lightning. It's not trivial, but I believe it's worth pursuing. I am fully supportive of payments taking off in Bitcoin," Armstrong stated at the time. "I'm not sure why you believe we are disregarding Bitcoin — we have onboarded more people to Bitcoin than probably any other company globally. Let's collaborate to build it."

「我們正在探索整合閃電網路的最佳方法。這並不簡單，但我相信它值得追求。我完全支持比特幣支付的起飛，」阿姆斯壯當時表示。 “我不知道為什麼你會認為我們忽視了比特幣——我們接納比特幣的人數可能比全球任何其他公司都多。讓我們合作構建它。”

Coinbase Joins the Lightning Network Vanguard

Coinbase 加入閃電網路先鋒

Coinbase joins a growing roster of major crypto exchanges offering Lightning support, including Bitfinex, OKX, Kraken, and Binance. Bitfinex emerged as the first major crypto exchange to embrace Lightning Network support in 2019. OKX followed suit in 2021, while Kraken and Binance completed their integrations in 2022 and July 2023, respectively.

Coinbase 加入了越來越多提供閃電網路支援的主要加密貨幣交易所行列，其中包括 Bitfinex、OKX、Kraken 和 Binance。 Bitfinex 於 2019 年成為第一個支援閃電網路的主要加密貨幣交易所。

When questioned about Coinbase's extended timeline for integrating the Lightning Network compared to its rivals, Bunin attributed it to a methodical approach involving evaluation of the Layer 2's growth and adoption before implementing support.

當被問及 Coinbase 與競爭對手相比整合閃電網路的時間較長時，布寧將其歸因於一種系統方法，包括在實施支援之前評估第 2 層的成長和採用。

"Coinbase's mission is to expand economic freedom globally, and supporting Bitcoin is integral to that endeavor. We examined Lightning support for several years before resolving to add it last year," Bunin explained to The Block. "The primary factors driving our decision were the sustained growth and adoption of Lightning, the increasing maturity of the underlying technology, and our objective to reduce onchain payments to 1 second and 1 cent."
