Improving Lending Protocol Performance with the OEV Network

利用 OEV 网络提高借贷协议性能

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市场升级以提升开发者体验的同时,API3即将推出OEV网络以优化借贷协议效率。

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.

区块链应用程序利用预言机检索链下数据(例如价格信息)并将其带入链上。大多数依赖于预言机的协议通过抢先交易、套利和清算成为价值提取(MEV)的目标。借贷协议现在认识到其生态系统的巨大价值被窃取,每年损失高达数百万美元。

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.

在过去三年中,仅 Aave 就见证了所有链上的清算额超过 20 亿美元,其中超过 1 亿美元用于清算激励。虽然这些清算奖金对于维持协议健康至关重要,但它们会导致搜索者和区块构建者大量价值泄漏,从而导致用户体验不佳。

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 网络的引入是为了通过创建一个高效的市场来回收这种价值,在这个市场中,预言机服务提供商和搜索者汇聚在一起,通过专门的订单流拍卖来减轻 MEV 的负面影响。有了 OEV 网络,搜索者不再需要等待链上的价格更新;当其价值最大化时,他们可以触发价格更新。作为特定于应用程序的解决方案,它捕获由于预言机更新而在协议级别生成的高达 90% 的 MEV,并将其返回给生成该值的 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 网络通过解决当前预言机设计空间中的基本低效率问题,为每个借贷协议提供内在的 MEV 解决方案。通过建立一个有效的预言机更新市场,不仅提高了借贷协议的效率,还使他们能够利用数百万美元的机会。

Lending Protocols Will Never Be the Same

借贷协议将永远不同

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 网络引入了市场动态的根本性转变,这将彻底改变贷款协议的清算游戏,改善其整体健康状况并最大限度地减少清算造成的价值损失的负面外部性。该设计维护了数据源的安全保证,同时允许拍卖和恢复预言机更新生成的价值。

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 网络体现了预言机架构的演变,提高了借贷协议的性能、效率和可持续性。通过重新获得目前因借贷协议而损失的高达 90% 的 MEV,OEV 网络开启了新的创新途径,通过授权协议提供更高的收益、更低的费用或新颖的功能来改变链上借贷体验。

Lending protocols will be irrevocably altered.

贷款协议将发生不可撤销的改变。

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 的初衷并不是要打败百视达,而是要打败百视达。他们从事不同的竞争领域。作为市场主导力量,百视达固步自封。然而,Netflix 优先考虑创新。最终,一个平台是用户友好的、高效的,可以在用户需要时提供他们想要的东西,并为他们节省金钱。

In retrospect, the choice was self-evident.

回想起来,这个选择是不言而喻的。
