Web3適用於我們其他人：一個簡單的區塊鏈，智能合約和DAPP的指南

區塊鏈技術記錄每個人都可以檢查的鏈接塊中的每個交易。本指南將以明確的步驟來解釋區塊鏈，智能合約，分散應用程序和數字錢包，因此您可以探索Web 30而不會混淆。作者：彼得·澤倫卡（Peter Zelenka）。更新：2023年4月18日。

In the bustling crypto chat, where terms like blockchain and smart contracts are casually tossed about, it's easy to feel lost if you're just starting your Web3 journey. Imagine someone mentioning a "DeFi protocol" or a "non-fungible token" and your mind blankly stalls, desperately seeking the "Beginners Guide to Crypto."

在繁華的加密聊天中，諸如區塊鍊和智能合約之類的術語被隨便扔掉，如果您剛剛開始Web3旅程，就很容易感到迷失。想像一下，有人提到“ Defi協議”或“不可殺死的令牌”，而您的頭腦茫然地停下來，拼命尋求“加密初學者指南”。

But fear not, for this guide will gently unravel the mysteries of blockchain, smart contracts, decentralized applications, and digital wallets in clear steps. We'll slash the gunk of jargon and untangle concepts like decentralization and dApps to seamlessly integrate into the fabric of Ethereum.

但是，不要擔心，因為本指南將在明確的步驟中輕輕揭開區塊鏈，智能合約，分散應用程序和數字錢包的奧秘。我們將削減行話和解散概念（例如權力中心化和dapps）的笨拙概念，以無縫整合到以太坊的結構中。

Visualize a potluck where no chef owns the recipe, and people store information on a distributed ledger in a peer-to-peer network (P2P), not on central servers. They guard their digital wallet keys and run code through smart contracts on a public blockchain network.

在沒有廚師擁有該食譜的地方可視化一個potluck，人們將信息存儲在點對點網絡（P2P）中，而不是中央服務器上。他們在公共區塊鍊網絡上通過智能合約來保護數字錢包鍵並運行代碼。

Anyone can build or join decentralized apps with no gatekeepers. They can swap ERC-20 tokens, mint non-fungible tokens, or try DeFi with a hardware wallet. This new web gives users control of data and cuts out the middleman.

任何人都可以在沒有看門人的情況下構建或加入分散的應用程序。它們可以交換ERC-20代幣，薄荷薄荷的不可殺菌令牌，也可以用硬件錢包嘗試Defi。這個新的網絡為用戶提供了對數據的控制並削減了中間人。

Now, let's break down the differences between Web1, Web2, and Web3.

現在，讓我們分解Web1，Web2和Web3之間的差異。

Web1.0, born in the 1990s, let people only read static pages on the world wide web. Developers used early web development tools to craft basic websites.

Web1.0出生於1990年代，讓人們只能在萬維網上閱讀靜態頁面。開發人員使用早期的Web開發工具來製作基本網站。

Then, Google, Facebook, and Amazon shaped Web2.0, filling feeds with posts, targeted ads, and rich media. They held all user data on central servers and steered digital experiences.

然後，Google，Facebook和Amazon塑造了Web2.0，並用帖子，有針對性的廣告和豐富的媒體填充提要。他們持有中央服務器上的所有用戶數據並轉向數字體驗。

A new era hands control back to people. It runs on a public blockchain network that powers smart contracts and dApps in the Ethereum Virtual Machine. Users store assets in digital wallets and swap tokens or cryptocurrencies on decentralized exchanges. They tap into decentralized finance, join yield farming, or mint non-fungible tokens for art. Platforms support supply chain management, decentralized identity, and digital democracy.

一個新時代的手控制回到人們。它在一個公共區塊鍊網絡上運行，該網絡為以太坊虛擬機中的智能合約和DAPP提供動力。用戶將資產存儲在數字錢包中，並在分散交易所交換代幣或加密貨幣。他們利用分散的金融，加入養殖養殖或薄荷污染物的藝術品。平台支持供應鏈管理，分散的身份和數字民主。

Now, let's introduce core concepts: blockchain, decentralization, and dApps.

現在，讓我們介紹核心概念：區塊鏈，權力下放和DAPP。

Blockchain forms the backbone of Web3 as a transparent, tamper-proof digital ledger. It logs every Bitcoin move, token swap, and NFT mint on public blockchains. A single block change needs new proofs across the network, so no one can cheat records.

區塊鏈形成Web3的骨幹，作為透明的防篡改數字分類帳。它可以在公共區塊鏈上記錄每個比特幣移動，代幣交換和NFT薄荷。單個塊更改需要整個網絡上的新證明，因此沒有人可以作弊記錄。

Decentralization shifts control to people, not big firms, and it fuels Web3's digital democracy. dApps run on blockchain networks, powered by smart contracts, and they serve shopping, gaming, or DeFi needs. People tap a digital wallet, guard private keys, then swap tokens or trade on decentralized exchanges.

權力下放將控制權轉移到了人們，而不是大公司，並為Web3的數字民主提供了助理。 DAPPS在區塊鍊網絡上運行，由智能合約提供支持，並提供購物，遊戲或Defi的需求。人們點擊數字錢包，防護私鑰，然後交換令牌或交易分散交易所。

I'll break down chain ledgers and digital cash in plain talk to kickstart your defi or NFT journey. Dig into our hands-on guides, grab node.js snippets, and run smart scripts in minutes.

我將在簡單的談話中分解鏈分類帳和數字現金，以啟動您的defi或nft旅程。挖掘我們的動手指南，獲取Node.js片段，並在幾分鐘內運行智能腳本。

1. Blockchain

1。區塊鏈

Imagine a chain of clear blocks. Each block holds a list of transactions. The chain links blocks by date to keep order. The ledger stays open for all to see. People cannot change past entries.

想像一下一連串的透明塊。每個塊都包含交易列表。鏈條鏈接按日期封鎖以保留訂單。分類帳留下來供所有人看。人們不能改變過去的條目。

Ethereum uses this type of ledger to run smart contracts. Developers call the chain through APIs or a JavaScript runtime script. You store funds in a digital wallet. Decentralized exchanges tap that data to swap tokens.

以太坊使用這種類型的分類帳來運行智能合約。開發人員通過API或JavaScript運行時腳本調用鏈條。您將資金存儲在數字錢包中。分散的交換點擊該數據以交換令牌。

2. Smart Contracts

2。智能合約

Self-executing code sits on a blockchain and acts like a vending machine for money. You drop crypto, and it spits out a non-fungible token, token or Ether, no clerk in sight. Smart contracts power dApps on Ethereum and fuel decentralized finance [defi] by cutting middlemen and slashing fees.

自我執行的代碼位於區塊鏈上，就像售貨機一樣。您放下加密貨幣，然後吐出一個不可殺死的令牌，令牌或以太，看不見的店員。 Smart Contract Contract Contract Power在以太坊和燃料分散的金融[Defi]上進行削減，通過削減中間人和削減費用。

Your digital wallet talks straight to the chain, and code locks in deals with digital signatures. Coders write contracts in Solidity or use server-side runners like Node.js to test them. They deploy on the Ethereum Virtual Machine with tools from the Ethereum Foundation. Each swap on a decentralized exchange, loan to a liquidity provider or mint of a non-fungible token logs on-chain for blockchain security and transparency.

您的數字錢包直接與鏈條進行對話，並與數字簽名交易中的代碼鎖定。編碼人員以堅固性或使用Node.js（例如JS）來測試合同。他們使用以太坊基金會的工具在以太坊虛擬機上部署。每次交換，分散的交易所，向流動性提供商貸款或造幣廠的薄荷，以鏈接鏈上的鏈接鏈，以獲得區塊鏈安全性和透明度。

No single server holds the data, so hackers hit a solid wall, and users keep control.

沒有一個服務器持有數據，因此黑客撞到了堅固的牆壁，用戶保持控制。

3. Decentralized Applications [dApps]

3。分散申請[DAPPS]

Some decentralized exchanges and NFT marketplaces run on Ethereum chains. They live on blockchain networks, not on single servers. Each dApp uses smart contracts to handle data with clear rules.

一些分散的交流和NFT市場在以太坊鏈上運行。它們生活在區塊鍊網絡上，而不是單個服務器上。每個DAPP都使用智能合約來處理具有明確規則的數據。

You open a digital wallet, enter a seed phrase, and you can trade tokens and cryptocurrencies on a decentralized exchange.

您打開一個數字錢包，輸入種子短語，然後可以通過分散的交換交易代幣和加密貨幣。

Artists mint non-fungible tokens [nfts] on marketplace dApps. Defi platforms let you lend or borrow digital coins without a bank. The code runs by itself, so no one can flip the switch.

藝術家在市場dapps上造成不可殺死的代幣[NFTS]。 Defi平台可讓您在沒有銀行的情況下借入或借用數字硬幣。該代碼單獨運行，因此沒有人可以翻轉開關。

Users see every move on the chain, and that builds integrity.

用戶看到鏈條上的每一步，這會建立完整性。

4. Tokens and Cryptocurrencies

4。令牌和加密貨幣

A cryptocurrency acts as digital cash on a network. You store it in a digital wallet. Bitcoin and Ethereum rank at the top

加密貨幣在網絡上充當數字現金。您將其存儲在數字錢包中。比特幣和以太坊排名最高
