Uniswap 是交易量最大的去中心化交易所,背後的公司已加入以太坊 L2 競賽,專注於去中心化金融領域用戶的需求。
Uniswap Labs, the company behind the namesake decentralized exchange, has announced the launch of Unichain, an Ethereum L2 focused on the needs of users in the decentralized finance space.
同名去中心化交易所背後的公司 Uniswap Labs 宣布推出 Unichain,這是一個專注於去中心化金融領域用戶需求的以太坊 L2。
The nascent scaling solution is built by Uniswap Labs on Optimism's Superchain, a unified network of layer 2 blockchains built using the OP Stack.
新生的擴展解決方案由 Uniswap Labs 在 Optimism 的 Superchain 上構建,Superchain 是使用 OP Stack 構建的第 2 層區塊鏈的統一網路。
“One of the biggest benefits of Optimism is just that I think it’s a standard a lot of people can converge around… We’re excited for their vision of interoperability and being able to partner with Optimism, partner with Base, and really prove out the Ethereum roadmap of interoperable L2s,” Uniswap Labs CEO Hayden Adams told Unchained.
「Optimism 最大的好處之一是,我認為這是一個很多人都可以共同遵守的標準……我們對他們的互通性願景感到興奮,並且能夠與 Optimism、Base 合作,並真正證明了Uniswap Labs 首席執行長Hayden Adams 告訴Unchained,以太坊可互通的L2 路線圖。
Optimism's OP Mainnet, and Coinbase-incubated Base are in the Superchain ecosystem.
Optimism 的 OP 主網和 Coinbase 孵化的 Base 都在 Superchain 生態中。
The new network, which is live on a private testnet and is expected to roll out in the next few months, has two key features – verifiable block building and a validation network – according to its whitepaper written by a number of people such as Adams, Flashbots strategy lead Hasu, OP Labs CEO Karl Floersch, and Paradigm general partner Dan Robinson.
新網絡在私人測試網上運行,預計將在未來幾個月內推出,根據 Adams 等多位人士撰寫的白皮書,它具有兩個關鍵功能——可驗證的區塊構建和驗證網絡, Flashbots 戰略主管Hasu 、OP Labs 執行長Karl Floersch 和Paradigm 普通合夥人Dan Robinson。
Created in collaboration with Flashbots, a research and development firm known for its focus on maximal extractable value (MEV), verifiable block building is ideally designed to help Unichain have 200-250 millisecond block times.
可驗證的區塊建置是與 Flashbots 合作創建的,Flashbots 是一家以專注於最大可提取價值 (MEV) 而聞名的研發公司,其理想設計旨在幫助 Unichain 擁有 200-250 毫秒的出塊時間。
An Already Crowded L2 Ecosystem
已經擁擠的 L2 生態系統
Uniswap Labs unveiling Unichain marks an additional entrant into the already populated L2 arena. At press time, the number of L2 protocols attempting to help scale Ethereum currently stands at 105 with Arbitrum, Base, and OP Mainnet taking the top three ranks by total value locked, per Ethereum scaling solution analytics platform L2Beat.
Uniswap Labs 推出 Unichain 標誌著已經很擁擠的 L2 領域又一個進入者。根據以太坊擴展解決方案分析平台 L2Beat,截至發稿時,試圖幫助擴展以太坊的 L2 協議數量目前為 105 個,其中 Arbitrum、Base 和 OP Mainnet 按鎖定總價值排名前三。
As to why Uniswap Labs is introducing yet another L2, Adams told Unchained he wants Unichain to improve the fragmented user experience of DeFi in which liquidity on each network is siloed from capital on the others. The company intends to do that by making it easy for users and developers to access liquidity across the Superchain.
至於 Uniswap Labs 為何要引入另一個 L2,Adams 告訴 Unchained,他希望 Unichain 能夠改善 DeFi 分散的使用者體驗,在這種體驗中,每個網路上的流動性與其他網路上的資本是相互隔離的。該公司打算透過讓用戶和開發者輕鬆獲得整個超級鏈的流動性來實現這一目標。
“We want to create a chain where other chains can interoperate with [each other] very easily,” Adams said. “If you have a token on one chain and you want to buy another token, that trade might execute on Unichain.”
「我們希望創建一條鏈,其他鏈可以非常輕鬆地相互操作,」亞當斯說。 “如果你在一個鏈上有一個代幣,並且你想購買另一個代幣,那麼該交易可能會在 Unichain 上執行。”
Although Unichain will start with single-block, cross-chain messaging among all Superchain L2s, the company will also work on creating interoperability for all chains, not just ones in the Superchain ecosystem, by working on Ethereum Improvement Proposals, such as one around “cross chain intents,” an interface that will allow users to easily transact across chains.
儘管Unichain 將從所有超級鏈L2 之間的單塊、跨鏈訊息傳遞開始,但該公司還將透過制定以太坊改進提案,致力於為所有鏈(而不僅僅是超級鏈生態系統中的鏈)創建互通性,例如圍繞“跨鏈意圖”,一個允許用戶輕鬆跨鏈交易的介面。
Unichain’s Sequencer Versus Others
Unichain 的排序器與其他排序器
Unichain, like all, or at least the vast majority of L2s, depends on a single sequencer, a critical piece of rollup infrastructure charged with ordering and bundling transactions from the L2 before posting them to Ethereum’s base layer. Unichain’s validation network is expected to address the centralization risks associated with single-sequencer architectures.
Unichain 與所有 L2 或至少絕大多數 L2 一樣,依賴單一排序器,這是匯總基礎設施的關鍵部分,負責在將 L2 交易發佈到以太坊基礎層之前對交易進行排序和捆綁。 Unichain 的驗證網路有望解決與單序列器架構相關的中心化風險。
“While Unichain leverages a single sequencer for efficiency, it introduces further decentralization by allowing full nodes to help verify blocks by staking UNI,” the Uniswap’s blog post stated. “This approach reduces the risk of sequencers proposing conflicting or invalid blocks, which could delay transaction finality or expose users to financial risks from interacting with unfinalized blocks.”
Uniswap 的部落格文章指出:“雖然 Unichain 利用單個排序器來提高效率,但它允許完整節點通過抵押 UNI 來幫助驗證區塊,從而引入了進一步的去中心化。” “這種方法降低了排序器提出衝突或無效區塊的風險,這可能會延遲交易最終確定或使用戶因與未最終區塊交互而面臨財務風險。”
Most L2 sequencers are controlled by a single entity. For example, Base’s sequencer is dictated by Coinbase, which earns 100% of the fees generated by the sequencer. But Unichain has more than one party, namely Uniswap Labs and Flashbots, involved in its sequencer, plus the UNI stakers who act as a second layer of security. By participating in Unichain’s validation network, UNI stakers verify each block of transactions the sequencer builds.
大多數 L2 音序器由單一實體控制。例如,Base 的定序儀是由 Coinbase 支配的,Coinbase 賺取定序儀產生的費用的 100%。但 Unichain 的排序器涉及不只一個方,即 Uniswap Labs 和 Flashbots,以及充當第二層安全保障的 UNI 質押者。透過參與 Unichain 的驗證網絡,UNI 質押者驗證排序器所建構的每個交易區塊。
As a result, the fees Unichain garners from users transacting on the blockchain will be divided up amongst the various actors contributing to the network. “Sequencer will earn some fees for being a sequencer [and] the validation network will earn fees for being a validation network. These are two different roles within the ecosystem,” Adams said.
因此,Unichain 從用戶在區塊鏈上進行交易獲得的費用將在為網路做出貢獻的各個參與者之間分配。 「定序器將因成為定序器而賺取一些費用,並且驗證網路將因成為驗證網路而賺取費用。這是生態系統中的兩個不同角色,」亞當斯說。
UPDATE (Oct. 10 09:58 a.m. ET): A previous version of this story said “Optimism, aka OP Mainnet” which has since been revised to “Optimism’s OP Mainnet” for clarity. Optimism is the Collective, and the home of the Superchain, while OP Mainnet is a single blockchain.
更新(美國東部時間 10 月 10 日上午 09:58):本文的前一個版本稱“Optimism,又名 OP 主網”,為了清晰起見,現已將其修改為“Optimism 的 OP 主網”。樂觀是集體,是超級鏈的家,而OP主網則是單一的區塊鏈。
