Chainlink 正在解决什么问题？

Smart contracts are very powerful tools, allowing for operations such as transfers of value to be executed deterministically when pre-defined conditions are met. However, blockchains by themselves are self-contained. When it comes to reaching consensus about which transactions are valid, blockchain nodes are concerned with a very narrow set of parameters. Here’s a few examples:

智能合约是非常强大的工具，允许在满足预定义条件时确定性地执行价值转移等操作。然而，区块链本身是独立的。当就哪些交易有效达成共识时，区块链节点只关心一组非常狭窄的参数。下面是一些例子：

The total amount of cryptocurrency being transferred from one address to another (for example, during a token swap)

从一个地址转移到另一个地址的加密货币总量（例如，在代币交换期间）

The sequence number of a transaction within a block (for example, to ensure transactions are processed in the correct order)

区块内交易的序列号（例如，确保交易以正确的顺序处理）

The validity of a signature used to authorize a transaction (for example, to ensure that a private key was used to sign the transaction)

用于授权交易的签名的有效性（例如，确保使用私钥对交易进行签名）

Blockchains are good at determining whether transactions are adhering to their internal rules. However, they are not designed to validate data from external systems, for example the price at which a cryptocurrency is trading on an exchange. So, if you’re for example trying to create a DeFi app that needs pricing data from a crypto exchange, you’ll need some external help.

区块链擅长确定交易是否遵守其内部规则。然而，它们并不是为了验证来自外部系统的数据，例如加密货币在交易所交易的价格。因此，如果您尝试创建一个需要来自加密货币交易所的定价数据的 DeFi 应用程序，您将需要一些外部帮助。

A service that provides external data to smart contracts running on blockchains is called an oracle. Chainlink is the leading example of a decentralized oracle network, and it provides a wide range of data such as asset prices, reserves, climate data, verifiably random numbers, and much more.

为区块链上运行的智能合约提供外部数据的服务称为预言机。 Chainlink 是去中心化预言机网络的领先示例，它提供广泛的数据，例如资产价格、储备、气候数据、可验证的随机数等等。

Chainlink 的顶级竞争对手

1. Pyth

1. Python

Pyth is a decentralized oracle network that provides real-time price data, historical price data and verifiably random numbers to smart contracts on more than 80 supported blockchain platforms.

Pyth 是一个去中心化的预言机网络，可为 80 多个受支持的区块链平台上的智能合约提供实时价格数据、历史价格数据和可验证的随机数。

In the Pyth network, selected data providers send price data to Pyth’s oracle program. The data for each Pyth price feed is supplied by multiple data providers to ensure accuracy. The oracle program consolidates these multiple data sources into a single aggregate price, which has a confidence interval attached to it. Then, smart contract-based applications can pull the prices from the Pyth network when required.

在 Pyth 网络中，选定的数据提供商将价格数据发送到 Pyth 的预言机程序。每个 Pyth 价格源的数据由多个数据提供商提供，以确保准确性。预言机程序将这些多个数据源合并为一个总价格，并附有一个置信区间。然后，基于智能合约的应用程序可以在需要时从 Pyth 网络中获取价格。

A key part of the Pyth infrastructure is Pythnet, which is a blockchain network built using the Solana codebase as its foundation. This network communicates with other blockchain platforms through the Wormhole protocol.

Pyth 基础设施的关键部分是 Pythnet，它是一个使用 Solana 代码库作为基础构建的区块链网络。该网络通过虫洞协议与其他区块链平台进行通信。

PYTH serves as the governance token for the Pyth Network, allowing holders to determine key decisions related to the network.

PYTH 作为 Pyth 网络的治理代币，允许持有者确定与网络相关的关键决策。

2. Band Protocol

2. 频段协议

Band Protocol is a decentralized oracle network that provides price data and verifiably random numbers to smart contracts. Band’s price feeds cover more than 175 crypto assets, but also include certain foreign exchange pairs and commodities to enable new types of decentralized applications.

Band Protocol 是一个去中心化的预言机网络，为智能合约提供价格数据和可验证的随机数。 Band 的价格信息涵盖超过 175 种加密资产，还包括某些外汇对和商品，以支持新型去中心化应用程序。

Band Protocol is integrated with variety of blockchain platforms, including Ethereum, BNB Chain, NEAR Protocol, Fantom and several others.

Band Protocol 与多种区块链平台集成，包括以太坊、BNB Chain、NEAR Protocol、Fantom 等。
