Polkadot 是一個去中心化的多鍊網絡，由以太坊聯合創始人 Gavin Wood 創建。

Polkadot is a decentralized multi-chain network founded by Ethereum co-founder Gavin Wood. It operates as a "Layer 0" blockchain, where its base chain (Relay chain) provides security and interoperability to multiple Layer 1's built on top of it, known as parachains.

Polkadot 是一個去中心化的多鍊網絡，由以太坊聯合創始人 Gavin Wood 創立。它作為「第 0 層」區塊鏈運行，其基礎鏈（中繼鏈）為構建在其之上的多個第 1 層（稱為平行鏈）提供安全性和互通性。

To use Polkadot, you'll need a wallet compatible with the network, like SubWallet or Talisman. Polkadot's native token is DOT, so to start using the chain, fund your Polkadot wallet with some DOT. You can acquire DOT on the Polkadot network by transferring funds from a centralized exchange (CEX) like Coinbase or Binance, or through a native bridge solution like Acala.

要使用 Polkadot，您需要一個與網路相容的錢包，例如 SubWallet 或 Talisman。 Polkadot 的原生代幣是 DOT，因此要開始使用該鏈，請用一些 DOT 為您的 Polkadot 錢包充值。您可以透過從 Coinbase 或 Binance 等中心化交易所 (CEX) 轉移資金，或透過 Acala 等本機橋接解決方案來取得 Polkadot 網路上的 DOT。

Most of the top applications on Polkadot can be found directly in the dApp directory. Within the directory, you can explore dApps and parachains that are built specifically for their niches, such as DeFi, NFTs, real-world assets (RWA), and decentralized exchanges (DEXs).

Polkadot 上的大多數頂級應用程式都可以直接在 dApp 目錄中找到。在該目錄中，您可以探索專為其利基市場構建的 dApp 和平行鏈，例如 DeFi、NFT、現實世界資產 (RWA) 和去中心化交易所 (DEX)。

The user experience on Polkadot is quite similar to that of Ethereum and Solana. For instance, when using the NFT platform KodaDot, you can start by connecting your wallet in the top right-hand corner using the "connect" button, and then proceed to buy, sell, and browse NFT collections.

Polkadot 上的使用者體驗與以太坊和 Solana 非常相似。例如，在使用 NFT 平台 KodaDot 時，您可以先使用右上角的「連接」按鈕連接錢包，然後繼續購買、出售和瀏覽 NFT 收藏品。

Currently, there are over 300 different dApps to choose from in the Polkdaot ecosystem. Out of these, some of the most popular applications include its cross-chain utility hub, Acala, DEX's such as HydraDX and Beamswap, and DeFi lending protocol Centrifuge.

目前，Polkdaot 生態中有超過 300 個不同的 dApp 可供選擇。其中，一些最受歡迎的應用程式包括其跨鏈實用中心 Acala、HydraDX 和 Beamswap 等 DEX 以及 DeFi 借貸協議 Centrifuge。
