我们之前的讨论解释了区块链预言机是什么,以及它们为何是智能合约支持链的重要基础设施。 在这篇文章中,我们将深入探讨它们是如何构建的,以确保数据的准确性和链上数据传递的完整性。 🧵👇 首先,重要的是要认识到,并非所有区块链预言机都是平等的,也并非都服务于相同的目的。 不同的预言机之间存在显著的设计差异,例如 @chainlink、@UMAprotocol、@BandProtocol 和 @。 然而,为了简单起见,我们将以 Chainlink——最大的区块链预言机提供商——作为我们的主要例子,来说明区块链预言机的功能。 在我们之前的讨论中,我们解释了为什么像 @aave 这样的 DeFi 协议不能依赖于单一的链上来源,例如 Uniswap,来获取价格信息。 如果它们这样做,就会暴露于操纵的风险之中。 去中心化交易所的资产价格是由流动性池比例决定的,这可能会被恶意交易者通过使用闪电贷或他们自己的资本进行大额交易而扭曲。 这就是为什么像 Aave 这样的协议转向像 Chainlink 这样的预言机提供商,Chainlink 在表面上似乎完全解决了这个问题。 毕竟,Chainlink 并不依赖于像 Uniswap 这样的单一交易所;它从多个场所聚合价格数据,进行过滤,并在链上提供中位值。 但许多人忽视了一个更深层次的风险。 即使基础数据——无论是资产价格、天气数据还是其他任何东西——是从数十个来源聚合而来的,如果它是由单一的预言机提供的,那一切都是徒劳的。 信任单一的链下参与者诚实地行为并保持在线,重新引入了与依赖单一数据源相同的单点故障。 如果该预言机出现故障、被攻破或恶意行为,所有依赖它的链上协议都会立即暴露。 这就是为什么 Chainlink 和大多数其他区块链预言机提供商在设计时考虑了去中心化。 更具体地说,Chainlink 不是单一的预言机,而是由许多去中心化预言机网络(DONs)组成的异构网络。 每个 DON 提供独特的预言机服务,以满足其用户的需求。 例如,一个 DON 可能为以太坊区块链提供 ETH/USD 价格,另一个可能为 Arbitrum 提供流动质押代币(LSTs)的价格信息,第三个可能在 Polygon 和 Solana 之间转移代币。 此外,每个 DON 由多个由不同运营商运行的节点组成,通常使用他们自己的基础设施和数据源。这些可能包括像 Vodafone 这样的 Web2 电信提供商、领先的数据提供商,以及像 Infura 这样的 Web3 基础设施提供商。 这些节点独立获取、签名并报告数据,然后将其聚合成一个单一的、共识验证的值。 例如,一个由 31 个节点组成的 DON 可能会让每个节点独立获取多个中心化和去中心化交易所的 ETH 价格数据,并生成自己的中位值。 然后,所有节点的中位价格数据被聚合成一个单一的数据点(一个预言机报告),并由 DON 交付给预期的接收者——例如,像 Aave 这样的区块链应用。 为了将来自多个节点的数据聚合成一个单一的数据点,Chainlink 使用了一种称为链下报告(Off-Chain Reporting,OCR)的协议。 OCR 是一个允许节点在链下就单一数据点达成共识的系统。 它的工作原理如下: 首先,DON 中的每个节点独立从其选择的来源获取数据,并通过点对点通信层与网络的其余部分共享其签名报告。 例如,节点 A 可能报告 ETH 的价格为 $3,120,节点 B 可能说是 $3,125,节点 C 可能说是 $3,118,等等。 一旦收集到足够的报告,节点们使用共识算法就 ETH 的单一聚合价格达成一致——通常是所有提交的中位数。 然后,只有一个紧凑的报告,包含最终结果(ETH 在 USD 中的单一价格)和参与节点的聚合签名,才会在链上发布。 一旦报告提交,智能合约会使用这些聚合签名验证其真实性,然后接受其作为有效输入。 这闭合了循环,确保没有未签名或被篡改的数据能够注入到区块链中。 这种设计大幅降低了燃气费用并提高了可扩展性,同时保持了完全的去中心化和可验证性。 当然,去中心化只有在 DON 内的节点不能轻易合谋操纵结果的情况下才能有效。 如果其中少数节点能够协调提交虚假数据,那么这一切都将毫无意义。 为了防止这种情况,Chainlink 依赖于加密保证、经济激励和透明机制的组合。 👉每个节点对其响应进行加密签名,使每个提交都可以在链上进行验证和公开审计。这确保了任何偏离预期行为的情况都可以追溯到负责的运营商。 👉此外,节点在经济上被激励准确报告。它们质押 LINK 代币并因良好表现而获得费用,但如果它们行为不诚实,也有可能失去收入、声誉和潜在的质押资产。 最后,所有预言机活动——数据更新、节点身份、馈送参数和历史表现——都是完全透明的。 任何人都可以检查链上报告,以验证哪些节点参与、何时发生更新以及结果是如何聚合的。 如果某些节点表现不佳或无法正常工作,它们的声誉(以及潜在的收入)将受到影响,未来将没有人依赖它们。 本质上,Chainlink 的架构用验证取代了信任。 通过去中心化数据来源、聚合和交付,并用加密证明、经济激励和完全透明性来保护每一层,它确保区块链应用能够与现实世界互动,而不牺牲安全性或可靠性。

深度了解UMA

Universal Market Access (UMA) is an Ethereum-compatible toolbox designed to enable users to create enforceable agreements, including project-specific smart contracts. While UMA excels in facilitating financial agreements, it is also compatible with a wide range of decentralized applications (DApps). UMA is referred to as a "decentralized truth machine" on its official website, emphasizing its role in ensuring transparency and trust within the decentralized ecosystem.

What is UMA?

UMA is a protocol specifically designed for creating programmable digital assets, enabling users to replicate traditional assets in a virtual blockchain-native form. This is achieved through an Optimistic Oracle setup, which handles real-world aspects such as prices by sourcing off-chain data. The integration of these Oracles ensures a trustless and decentralized ecosystem. In addition to its financial applications, UMA offers a wide range of Web3 apps, including prediction markets, insurance bridges, and customizable decentralized autonomous organizations (DAOs), expanding its utility beyond financial markets.

The UMA team

The UMA team, founded in 2017, was envisioned and established by Hart Lambur and Allison Lu, both former Goldman Sachs traders. Lambur also co-founded the Risk Lab Foundation, a blockchain research company that supports the UMA project. The team comprises various experienced individuals, including John Shuttt as a senior engineer, Melissa Quinn as the COO, Clayton Roche as the head of community and development, and other talented professionals. Together, they contribute their expertise and skills to the success and development of the UMA project.

How does UMA work?

The OO system associated with the UMA ecosystem accepts statements and instances projected as truth. These instances come with bonds, transforming them into workable cases. Those who can prove the instances false are rewarded.

If no disputes or challenges arise, the proposed instance (statement) is added to the chain, becoming immutable and a part of the ecosystem. Each instance comprises three aspects: a request for information, proposed information, and a case for dispute.

If a dispute is raised and proven false, the disputer loses their token deposit, while the proposer receives a portion. If proven correct, the proposer loses their deposit, and the disputer gets a part of it.

With UMA, you can easily create financial products through synthetic tokens. These tokens track the value of real-world legacy assets such as gold. Additionally, UMA utilizes a proprietary implementation of its OO setup, the Data Verification Mechanism, to ensure that the synthetic assets always track the correct real-world price.

The process itself requires smart contract support. Finally, you can trade these UMA-based assets across DApps and markets.

Universal Market Access’s native token: UMA

UMA is the ecosystem's native token. UMA tokens are ERC-20 compatible and allow holders to participate in governance-related matters of the protocol. Plus, UMA tokens can also help increase the network's overall security.

UMA tokenomics

Based on ecosystem data, nearly 114 million UMA tokens exist. The maximum supply, accounting for lost tokens, slightly exceeds 100 million. When a proposal becomes active, the participating votes receive 0.05% of UMA's supply, which may contribute to network inflation.

How to stake UMA?

To stake UMA, you should visit UMA's dedicated staking application. Connect your crypto wallet and lock your UMA tokens within a smart contract for a designated period. The staked tokens generate an additional annual percentage rate (APR) as an incentive.

In addition to staking, exercising voting rights within the ecosystem also generates incentives. UMA's direct staking app features a comprehensive dashboard that displays the percentage of staked tokens, claimed and unclaimed rewards, and earnings based on voting participation.

UMA use cases

UMA, the native token of the UMA ecosystem, facilitates DAO governance and ensures network security. These tokens also empower trustless financial innovations, enabling the creation of various synthetic assets. Furthermore, UMA tokens contribute to dispute resolution, similar to the role of a juror. Additionally, these native tokens serve as incentives or rewards for developers who build upon the UMA ecosystem.

UMA token distribution

UMA tokens are allocated as follows:

  • 2 million UMA tokens were released during the ICO sale.
  • 48.5 million tokens are reserved for the founding team.
  • 35 million UMA tokens are designated as developer rewards.
  • 14.5 million tokens are allocated for sales and trading-based activities.

The road ahead for UMA

UMA's oracle-based contracts have undergone thorough audits, ensuring their security and reliability. The ecosystem boasts a transparent governance mechanism, providing decentralized finance (DeFi) exposure through cross-chain bridges. UMA also features a pioneering, Optimistic Oracle setup, making it a forward-looking ecosystem.

UMA's credibility in the DApp and DeFi space is further reinforced by hosting innovative products such as Sherlock, a Risk Management platform, and Polymarket, a market for information. These offerings contribute to UMA's reputation and solidify its position in the industry.
