ERC-20是以太坊上使用最廣泛的令牌標準。這就是意思。

ERC-20是一種技術標準（或代幣標準），它定義了以太坊生態系統中可易換令牌的功能

ERC-20 is the most widely used token standard on Ethereum. It provides a simple, consistent set of rules that developers can use to mint and manage fungible tokens – digital assets that each hold the same value and utility.

ERC-20是以太坊上使用最廣泛的令牌標準。它提供了一套簡單，一致的規則集，開發人員可以使用這些規則來鑄造和管理可及的代幣 - 每個數字資產，每個資產都具有相同的價值和實用性。

For example, all ERC-20 tokens have the same functions for checking a user's token balance or transferring tokens between wallets. This standardisation is crucial for the interoperability of different crypto projects and platforms. Without such a standard, the exponential growth of new crypto tokens, wallets, and exchanges would likely have been much more complex and difficult to use.

例如，所有ERC-20代幣具有相同的功能，用於檢查用戶的令牌餘額或在錢包之間傳輸令牌。該標準化對於不同加密項目和平台的互操作性至關重要。沒有這樣的標準，新的加密代幣，錢包和交換的指數增長可能會更加複雜和難以使用。

In this guide, we will detail what ERC-20 means, how it works, why it’s so important, and how it compares with other top Ethereum token standards like ERC-721 and ERC-1155.

在本指南中，我們將詳細介紹ERC-20的含義，其工作方式，為什麼如此重要，以及如何與其他以太坊標記標準（如ERC-721和ERC-1155）進行比較。

What Does ERC-20 Mean?

ERC-20意味著什麼？

ERC-20 is a technical standard (or token standard) that defines how fungible tokens function in the Ethereum ecosystem, outlining a set of rules for transferring tokens, checking balances, and approving spending. This standard acts like a “rulebook” for developers, helping them create tokens that are compatible with the rest of the Ethereum ecosystem, such as crypto wallets, decentralized applications (dApps), and exchanges.

ERC-20是一種技術標準（或代幣標準），它定義了以太坊生態系統中的可函件功能，概述了一組轉移令牌，檢查餘額和批准支出的規則。該標準對開發人員來說就像是“規則手冊”，幫助他們創建與其他以太坊生態系統兼容的代幣，例如加密錢包，分散應用程序（DAPP）和交流。

It’s important to note that ERC-20 is specific to fungible tokens. This simply means that each token is interchangeable with any other token of the same kind, similar to fiat currencies. For example, one ETH is always interchangeable with any other ETH.

重要的是要注意，ERC-20是特定於可及代幣的。這僅意味著每個令牌都可以與類似於法定貨幣的其他任何同類幣互換。例如，一個ETH總是可以與任何其他ETH互換。

What Is An ERC?

什麼是ERC？

The “ERC” in ERC-20 (and every other Ethereum token standard) stands for Ethereum Request for Comment. ERCs are proposals that suggest some kind of technical improvements or standards for how things should function on the Ethereum network. Because Ethereum is an open-source, decentralized platform with no central authority, the ERC system allows developers to submit ideas to be reviewed and further refined by the broader Ethereum community.

ERC-20中的“ ERC”（以及其他所有以太坊標準標準）代表以太坊請求置評請求。 ERC是提出的建議，建議某種技術改進或標準事物在以太坊網絡上的運作。由於以太坊是一個沒有中央權威的開源，分散的平台，因此ERC系統允許開發人員提交想法，並由更廣泛的以太坊社區進行審查並進一步完善。

An ERC is created through the following process:

通過以下過程創建ERC：

The number “20” in ERC-20 simply identifies this specific proposal. Other major ERCs include ERC-721, the most popular token standard for non-fungible tokens (NFTs), and ERC 1155, a multi-token standard used in many blockchain games that allows both fungible and non-fungible tokens in one contract.

ERC-20中的數字“ 20”只是標識了這一特定建議。其他主要的ERC包括ERC-721，這是最受歡迎的非避免令牌（NFTS）的標準標準，以及ERC 1155，這是許多區塊鏈遊戲中使用的多token標準，允許一份合同中允許易於及格和不可殺死的令牌。

The History of ERC-20

ERC-20的歷史

Before ERC-20, each new blockchain-based token had its own custom code, making it difficult for wallets, exchanges, and decentralized applications (dApps) to support them.

在ERC-20之前，每個新的基於區塊鏈的令牌都有自己的自定義代碼，這使得錢包，交換和分散應用程序（DAPP）很難支持它們。

ERC-20 was proposed by an Ethereum developer called Fabian Vogelstellar on November 19, 2015. The idea was to create a standard so that all tokens follow the same set of rules, ensuring compatibility across the Ethereum ecosystem. He posted the proposal on GitHub, a platform where developers store and share code. Vogelstellar explained why this process is so important in driving innovation in an interview at Devcon3 if you want to hear more.

ERC-20由一位名為Fabian Vogelstellar的以太坊開發人員於2015年11月19日提出。這個想法是創建標準，以便所有令牌遵循相同的規則，以確保整個以太坊生態系統的兼容性。他在Github上發布了該提案，該提案是開發人員存儲和共享代碼的平台。 Vogelstellar解釋了為什麼如果您想听到更多的話，在DevCon3的一次採訪中，這一過程在推動創新中如此重要。

The proposal was recognized in late 2017 and formalized in Ethereum Improvement Proposal 20 (EIP-20), which was written by Vogelstellar and Vitalik Buterin, a cofounder of Ethereum, and can be viewed here.

該提案在2017年底得到認可，並在以太坊改善提案20（EIP-20）中正式化，該提案是由以太坊共同創始人Vogelstellar和Vitalik Buterin撰寫的，可以在此處查看。

ERC-20 came to the forefront during the 2017/18 initial coin offering (ICO) boom. An ICO is similar to an initial public offering (IPO) but for a new cryptocurrency instead of a stock. Most tokens launched during this period were on the Ethereum network, and ERC-20 became the industry standard. There are now more than 350 thousand ERC-20 assets.

ERC-20在2017/18年度的初始硬幣產品（ICO）繁榮中走到了最前沿。 ICO類似於首次公開發行（IPO），但對於新的加密貨幣而不是股票。在此期間發布的大多數令牌都在以太坊網絡上，而ERC-20成為行業標準。現在有超過3.5萬ERC-20資產。

How ERC-20 Tokens Work

ERC-20令牌如何工作

ERC-20 tokens serve a wide range of purposes on the Ethereum network. They can represent digital currencies, voting power in governance systems, or even tokenized versions of real-world assets such as real estate or gold. These tokens are powered by smart contracts, which are self-executing lines of code stored on the Ethereum blockchain. These contracts automatically perform specific functions, such as processing transactions, when certain predetermined conditions are met.

ERC-20代幣在以太坊網絡上提供了廣泛的目的。它們可以代表數字貨幣，在治理系統中的投票權，甚至代表現實世界中的現實資產（例如房地產或黃金）的標記版本。這些令牌由智能合約提供動力，智能合約是存儲在以太坊區塊鏈上的自我執行的代碼線。當滿足某些預定條件時，這些合同會自動執行特定的功能，例如處理交易。

When a developer creates an ERC-20 token, they write a smart contract that defines the token’s name, symbol, supply, and how transactions should work. The contract must implement standard ERC-20 functions. For example, balanceOf() allows the user to check their balance while transfer() instructs the contract to send tokens from one wallet to another. Normally, this would require a strong understanding of coding and Solidity, the coding language used on Ethereum, but today, there are platforms that can help you create tokens much more easily.

當開發人員創建ERC-20代幣時，他們寫了一份智能合約，以定義令牌的名稱，符號，供應以及交易應如何工作。合同必須實施標準ERC-20功能。例如，BalanceOf（）允許用戶在轉移（）指示合同將令牌從一個錢包發送到另一個錢包時檢查其餘額。通常，這將需要對以太坊上使用的編碼語言有深入的了解，但是今天，有些平台可以幫助您更輕鬆地創建令牌。

This standardization has fueled the rapid growth of DeFi by enabling developers to build interoperable wallets, decentralized exchanges, lending apps, and other DeFi platforms without the need for custom coding. As a result, users can easily trade, lend, stake

這種標準化通過使開發人員能夠構建可互操作的錢包，分散交易所，貸款應用程序和其他Defi平台而無需自定義編碼，從而推動了Defi的快速增長。結果，用戶可以輕鬆交易，借貸，股份
