<h2>What is Polkadot?</h2>
<p>Polkadot is a sharded protocol that enables <a target="_blank" rel="noopener noreferrer" href="https://crypto.com/university/what-is-blockchain-consensus?utm_source=crypto.com+price+page&amp;utm_medium=referral&amp;utm_campaign=polkadot&amp;utm_content=blockchain">blockchain</a> networks to operate together. Polkadot is an open-source project founded by the Web3 Foundation, whose co-founder Dr Gavin Wood is credited with coming up with the term Web3. Polkadot facilitates the trustless sharing of information between public and private chains, permissionless networks, oracles, and future technologies. As a result of this function, Polkadot is recognised as a layer-0 metaprotocol that serves as the underlying network for layer-1 blockchains known as parachains (parallel chains). </p>
<p></p>
<h2>A brief history of Polkadot</h2>
<p>Polkadot was founded in 2016 by Gavin Wood, former Ethereum co-founder and CTO. In his view, the vision behind Polkadot was to deliver on <a target="_blank" rel="noopener noreferrer" href="https://gavofyork.medium.com/so-ethereum-is-released-4291da46b770">what Ethereum could not</a>. By October of that year, he had finished the first draft of the Polkadot white paper, which outlined his plans to create a new multi-chain ecosystem that would serve as a bridge to other blockchains. </p>
<p></p>
<p>In 2017, Dr Wood and Parity’s Peter Czaban founded the Web3 Foundation, which would later host Polkadot’s very first token sale in October 2017. The sale raised US$145 million through a public sale of half the total 10 million supply of its token DOT. It then raised a further $3.3 million in a private token sale in 2020.</p>
<p></p>
<h2>How Polkadot works</h2>
<p>Polkadot’s multi-chain technology allows different blockchains, which would otherwise not be able to interconnect, to transfer information in a trust-free fashion. Through Polkadot, these linked blockchains share their unique features and pool their security. The platform does this through four core components: a Relay Chain that creates interoperability and consensus between blockchains, independent chains called Parachains, Parathreadsd that provide flexible connectivity, and Bridges that link parachains and parathreads with external blockchains.</p>
<p></p>
<h2>What is Polkadot used for? </h2>
<p>As the native coin of its namesake blockchain, Polkadot (DOT) serves three distinct purposes: governance over the network, staking, and bonding.</p>

<h2>什麼是 Polkadot？</h2><p>Polkadot 是種分片協定，讓<a target="_blank" rel="noopener noreferrer" href="https://crypto.com/university/what-is-blockchain-consensus?utm_source=crypto.com+price+page&amp;utm_medium=referral&amp;utm_campaign=polkadot&amp;utm_content=blockchain">區塊鏈</a>網路可以共同運作.Polkadot 是由 Web3 基金會創立的開放源碼專案，而 Web3 一詞的起源，可歸功於共同創辦人 Gavin Wood 博士.Polkadot 促進資料在公用鏈和私有鏈、免許可網路、預測機和未來技術之間，以去信任化方式共享。有賴此功能，Polkadot 被認為是第 0 層後設協定，並作為第 1 層區塊鏈的底層網路，即平行鏈。</p><p></p><h2>Polkadot 簡史</h2><p>Polkadot 由前 Ethereum 共同創辦人兼首席科技總監 Gavin Wood 於 2016 年創立。依他之見，Polkadot 的願景是實現 <a target="_blank" rel="noopener noreferrer" href="https://gavofyork.medium.com/so-ethereum-is-released-4291da46b770">Ethereum </a>所無法做到的功能。同年 10 月，他完成 Polkadot 白皮書的初稿撰寫，內容描繪創建全新多鏈生態圈的計畫，該生態圈將成為連接其他區塊鏈的橋樑。</p><p></p><p>2017 年，Wood 博士和 Parity 的 Peter Czaban 成立 Web3 基金會，該基金會後來於 2017 年 10 月舉辦 Polkadot 的代幣首次銷售活動。透過該次公開發售，成功售出 DOT 總供應量 1000 萬枚的一半，籌得 1.45 億美元。其後於 2020 年，透過私人加密貨幣銷售活動，再籌得 330 萬美元。</p><p></p><h2>Polkadot 如何運作</h2><p>Polkadot 的多鏈技術讓原本無法相連的不同區塊鏈，能以去信任化方式相互傳送資料。透過 Polkadot，這些已連結的區塊鏈，可共享彼此的獨特功能，並共用安全保障。該平台透過四個核心部分來實現這一點：在區塊鏈之間建立互操作性和共識的中繼鏈、稱為平行鏈的獨立鏈、提供靈活連接的 Parathreadsd，以及將平行鏈和平行線程與外部區塊鏈連接起來的跨鏈橋。</p><p></p><h2>Polkadot 有什麼用途？ </h2><p>身為同名區塊鏈的原生加密貨幣，Polkadot (DOT) 擁有三種不同用途：網路治理、質押、綁定。</p><h2>How Polkadot works</h2><p>Polkadot’s multi-chain technology allows different blockchains, which would otherwise not be able to interconnect, to transfer information in a trust-free fashion.Through Polkadot, these linked blockchains share their unique features and pool their security.The platform does this through four core components: a Relay Chain that creates interoperability and consensus between blockchains, independent chains called Parachains, Parathreadsd that provide flexible connectivity, and Bridges that link parachains and parathreads with external blockchains.</p><p></p><h2>What is Polkadot used for? </h2><p>As the native coin of its namesake blockchain, Polkadot (DOT) serves three distinct purposes: governance over the network, staking, and bonding.</p>
