Evolution to Data on Demand

向按需資料的演變

The API3 Market was conceived as an open, self-service marketplace for utilizing decentralized data feeds, also known as dAPIs. Developers seeking to power their protocols with verifiable, decentralized data directly from first-party oracle nodes can access the API3 Market, where they can seamlessly explore, access, and manage a diverse range of data feeds, encompassing crypto, forex, equities, and commodities.

API3 市場被認為是一個開放的自助服務市場，用於利用去中心化資料來源（也稱為 dAPI）。尋求直接從第一方預言機節點使用可驗證、去中心化資料為其協議提供支援的開發人員可以存取API3 市場，在那裡他們可以無縫地探索、存取和管理各​​種資料來源，包括加密貨幣、外匯、股票和大宗商品。

As part of a significant upgrade to the API3 Market, API3 is introducing a Data on Demand marketplace for data feeds, replicating the ease of a web2 experience familiar to many developers. This next phase in the evolution of the API3 Market automates the procurement and configuration of data feeds through a straightforward Pay-and-Go process. This eliminates the need for developers working on blockchain networks and decentralized applications (dApps) to engage with intermediaries or human agents to access API3's vast data feed repository, simplifying the process of acquiring off-chain data.

作為 API3 市場重大升級的一部分，API3 正在引入資料來源的隨選資料市場，複製許多開發人員熟悉的 web2 體驗的便利性。 API3 市場發展的下一階段透過簡單的「即付即用」流程自動執行資料來源的採購和配置。這使得區塊鏈網路和去中心化應用程式 (dApp) 開發人員無需與中介機構或人工代理接觸來存取 API3 龐大的資料來源儲存庫，從而簡化了獲取鏈下資料的過程。

The API3 Market empowers developers requiring oracle services to acquire the data they need when they need it. Instead of managing their own infrastructure, developers can simply retrieve data that is meticulously maintained and stored on-chain.

API3市場使需要預言機服務的開發人員能夠在需要時取得他們需要的資料。開發人員無需管理自己的基礎設施，只需檢索精心維護和儲存在鏈上的資料即可。

API3 Market: Data on Demand

API3 市場：按需數據

Envision this transition as analogous to the shift from renting DVDs at Blockbuster to the convenience of Netflix's on-demand streaming service, but tailored specifically for blockchain developers.

設想這種轉變類似於從 Blockbuster 租賃 DVD 到 Netflix 的點播串流服務的便利轉變，但專門為區塊鏈開發人員量身定制。

API3's data-on-demand model not only democratizes access to the data essential for powering numerous DeFi protocols but also facilitates the rapid scaling and adoption of these data feeds across multiple chains. With the API3 Market upgrade, API3 embarks on its ambitious goal of expanding its oracle stack to over 40 blockchains this year, emphasizing Layer 2s.

API3 的按需資料模型不僅使對支援眾多 DeFi 協定所必需的資料的存取民主化，而且還促進了這些資料來源在多個鏈上的快速擴展和採用。隨著 API3 市場升級，API3 開始實現其雄心勃勃的目標，今年將其預言機堆疊擴展到 40 多個區塊鏈，並強調第 2 層。

The ability to scale horizontally to new chains stems from API3's EVM-compatible first-party oracle architecture and standardized dAPIs. This design enables API3 to integrate seamlessly with new networks, alleviating the bottlenecks encountered with third-party oracle models. API3 employs a vertical scaling strategy alongside the rapid deployment of on-chain data to new chains, enhancing data accessibility on each network. Designed with a focus on cost-effectiveness, dAPIs allow developers to acquire on-chain data directly without incurring additional fees, lowering the entry barriers for new projects on the network.

水平擴展至新鏈的能力源自於 API3 相容 EVM 的第一方預言機架構和標準化 dAPI。這種設計使API3能夠與新網路無縫集成，緩解第三方預言機模型遇到的瓶頸。 API3 採用垂直擴展策略，同時將鏈上資料快速部署到新鏈，從而增強每個網路上的資料可存取性。 dAPI 的設計注重成本效益，讓開發者可以直接取得鏈上數據，而無需支付額外費用，降低了網路新專案的進入門檻。

The network effects of the API3 Market amplify its utility. As the go-to destination for on-chain data, it minimizes the complexity and effort typically associated with designing a technology stack. API3 allows developers to concentrate on their core competencies, developing their applications, without the distractions of managing unnecessary infrastructure or coordinating with intermediaries.

Data on demand on the API3 Market is poised to revolutionize the developer experience, akin to how Netflix transformed content consumption by making a vast library of content available at the click of a button.

API3 市場上的隨選資料有望徹底改變開發者體驗，類似於 Netflix 透過點擊按鈕提供龐大的內容庫來改變內容消費的方式。

Improving Lending Protocol Performance with the OEV Network

利用 OEV 網路提高借貸協議效能

Concurrent with the API3 Market upgrade to enhance the developer experience, API3 will soon launch the OEV Network to optimize lending protocol efficiency.

在API3市場升級以提升開發者體驗的同時，API3即將推出OEV網路以優化借貸協議效率。

Blockchain applications utilize oracles to retrieve off-chain data, such as price feeds, and bring them on-chain. Most protocols that depend on oracles become targets for value extraction, or MEV, through frontrunning, arbitrage, and liquidations. Lending protocols are now recognizing the substantial value siphoned from their ecosystem, with losses amounting to millions of dollars annually.

區塊鏈應用程式利用預言機檢索鏈下資料（例如價格資訊）並將其帶入鏈上。大多數依賴預言機的協議透過搶先交易、套利和清算成為價值提取（MEV）的目標。借貸協議現在認識到其生態系統的巨大價值被竊取，每年損失高達數百萬美元。

In the past three years, Aave alone has witnessed liquidations exceeding $2 billion across all chains, with more than $100 million disbursed as liquidation incentives. While these liquidation bonuses are crucial for maintaining protocol health, they result in significant value leakage to searchers and block builders, leading to a suboptimal user experience.

在過去三年中，僅 Aave 就見證了所有鏈上的清算額超過 20 億美元，其中超過 1 億美元用於清算激勵。雖然這些清算獎金對於維持協議健康至關重要，但它們會導致搜尋者和區塊建構者大量價值洩漏，從而導致用戶體驗不佳。

The OEV Network is introduced to reclaim this value by creating an efficient marketplace where oracle service providers and searchers converge to mitigate the negative impact of MEV through specialized order-flow auctions. With the OEV Network, searchers are no longer obligated to wait for price updates on-chain; they can trigger the price update when its value is maximized. As an application-specific solution, it captures up to 90% of the MEV generated at the protocol level due to oracle updates and returns it to the dApp that generated the value.

OEV 網路的引入是為了透過創造一個高效的市場來回收這種價值，在這個市場中，預言機服務提供者和搜尋者匯聚在一起，透過專門的訂單流拍賣來減輕 MEV 的負面影響。有了 OEV 網絡，搜尋者不再需要等待鏈上的價格更新；當其價值最大化時，他們可以觸發價格更新。作為特定於應用程式的解決方案，它捕獲由於預言機更新而在協議級別生成的高達 90% 的 MEV，並將其返回給生成該值的 dApp。

The OEV Network provides every lending protocol an intrinsic MEV solution by addressing fundamental inefficiencies in the current oracle design space. By establishing an efficient marketplace for oracle updates, it not only enhances the efficiency of lending protocols but also enables them to capitalize on a multi-million dollar opportunity.

OEV 網路透過解決目前預言機設計空間中的基本低效率問題，為每個借貸協議提供內在的 MEV 解決方案。透過建立一個有效的預言機來更新市場，不僅提高了借貸協議的效率，還使他們能夠利用數百萬美元的機會。

Lending Protocols Will Never Be the Same

借貸協議將永遠不同

The OEV Network introduces a fundamental shift in market dynamics that will revolutionize the liquidation game for lending protocols, improving their overall health and minimizing the negative externalities of value loss due to liquidations. The design upholds the data feed's security guarantees while permitting the auctioning and recovery of the value generated by oracle updates.

OEV 網路引入了市場動態的根本性轉變，這將徹底改變貸款協議的清算遊戲，改善其整體健康狀況並最大限度地減少清算造成的價值損失的負面外部性。該設計維護了資料來源的安全保證，同時允許拍賣和恢復預言機更新產生的價值。

The OEV Network embodies an evolution in oracle architecture, enhancing the performance, efficiency, and sustainability of lending protocols. By recapturing up to 90% of the MEV currently lost by lending protocols, the OEV Network unlocks new avenues for innovation, transforming the on-chain lending experience by empowering protocols to offer enhanced yields, reduced fees, or novel features.

OEV 網路體現了預言機架構的演變，提高了借貸協議的效能、效率和永續性。透過重新獲得目前因借貸協議而損失的高達 90% 的 MEV，OEV 網路開啟了新的創新途徑，透過授權協議提供更高的收益、更低的費用或新穎的功能來改變鏈上借貸體驗。

Lending protocols will be irrevocably altered.

貸款協議將發生不可撤銷的改變。

Netflix did not set out to vanquish Blockbuster; they were engaged in distinct competitive arenas. Blockbuster rested on its laurels as the prevailing market force. Netflix, however, prioritized innovation. Ultimately, one platform was user-friendly, efficient, provided what users desired when they desired it, and saved them money.

Netflix 的初衷不是要打敗百視達，而是要打敗百視達。他們從事不同的競爭領域。作為市場主導力量，百視達固步自封。然而，Netflix 優先考慮創新。最終，一個平台是用戶友好的、高效的，可以在用戶需要時提供他們想要的東西，並為他們節省金錢。

In retrospect, the choice was self-evident.

回想起來，這個選擇是不言而喻的。
