What problems is Chainlink solving?

Chainlink 正在解決什麼問題？

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:

智能合約是非常強大的工具，允許在滿足預定義條件時確定性地執行價值轉移等操作。然而，區塊鏈本身是獨立的。當哪些交易有效達成共識時，區塊鏈節點只關心一組非常狹窄的參數。以下是一些例子：

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

從一個地址轉移到另一個地址的加密貨幣總量（例如，在代幣交換期間）

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

區塊內交易的序號（例如，確保交易以正確的順序處理）

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

用於授權交易的簽名的有效性（例如，確保使用私鑰對交易進行簽署）

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.

區塊鏈擅長確定交易是否遵守其內部規則。然而，它們並不是為了驗證來自外部系統的數據，例如加密貨幣在交易所交易的價格。因此，如果您嘗試創建一個需要來自加密貨幣交易所的定價資料的 DeFi 應用程序，您將需要一些外部幫助。

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.

為區塊鏈上運行的智能合約提供外部數據的服務稱為預言機。 Chainlink 是去中心化預言機網路的領先範例，它提供廣泛的數據，例如資產價格、儲備、氣候數據、可驗證的隨機數等等。

Chainlink 的頂級競爭對手

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 是一個去中心化的預言機網絡，可為 80 多個受支援的區塊鏈平台上的智能合約提供即時價格數據、歷史價格數據和可驗證的隨機數。

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 網路中，選定的資料提供者將價格資料傳送到 Pyth 的預言機程式。每個 Pyth 價格來源的資料由多個資料提供者提供，以確保準確性。預言機程式將這些多個資料來源合併為一個總價格，並附有一個信賴區間。然後，基於智能合約的應用程式可以在需要時從 Pyth 網路中獲取價格。

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 基礎設施的關鍵部分是 Pythnet，它是一個使用 Solana 程式碼庫作為基礎構建的區塊鏈網路。該網路透過蟲洞協定與其他區塊鏈平台進行通訊。

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

PYTH 作為 Pyth 網路的治理代幣，允許持有者確定與網路相關的關鍵決策。

2. Band Protocol
