ERC-20是以太坊上使用最广泛的令牌标准。这就是意思。

ERC-20是一种技术标准（或代币标准），它定义了以太坊生态系统中可易换令牌的功能

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是以太坊上使用最广泛的令牌标准。它提供了一套简单，一致的规则集，开发人员可以使用这些规则来铸造和管理可及的代币 - 每个数字资产，每个资产都具有相同的价值和实用性。

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代币具有相同的功能，用于检查用户的令牌余额或在钱包之间传输令牌。该标准化对于不同加密项目和平台的互操作性至关重要。没有这样的标准，新的加密代币，钱包和交换的指数增长可能会更加复杂和难以使用。

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，我们将详细介绍ERC-20的含义，其工作方式，为什么如此重要，以及如何与其他以太坊标记标准（如ERC-721和ERC-1155）进行比较。

What Does ERC-20 Mean?

ERC-20意味着什么？

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是一种技术标准（或代币标准），它定义了以太坊生态系统中的可函件功能，概述了一组转移令牌，检查余额和批准支出的规则。该标准对开发人员来说就像是“规则手册”，帮助他们创建与其他以太坊生态系统兼容的代币，例如加密钱包，分散应用程序（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是特定于可及代币的。这仅意味着每个令牌都可以与类似于法定货币的其他任何同类币互换。例如，一个ETH总是可以与任何其他ETH互换。

What Is An ERC?

什么是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标准标准）代表以太坊请求置评请求。 ERC是提出的建议，建议某种技术改进或标准事物在以太坊网络上的运作。由于以太坊是一个没有中央权威的开源，分散的平台，因此ERC系统允许开发人员提交想法，并由更广泛的以太坊社区进行审查并进一步完善。

An ERC is created through the following process:

通过以下过程创建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中的数字“ 20”只是标识了这一特定建议。其他主要的ERC包括ERC-721，这是最受欢迎的非避免令牌（NFTS）的标准标准，以及ERC 1155，这是许多区块链游戏中使用的多token标准，允许一份合同中允许易于及格和不可杀死的令牌。

The History of ERC-20

ERC-20的历史

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，每个新的基于区块链的令牌都有自己的自定义代码，这使得钱包，交换和分散应用程序（DAPP）很难支持它们。

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由一位名为Fabian Vogelstellar的以太坊开发人员于2015年11月19日提出。这个想法是创建标准，以便所有令牌遵循相同的规则，以确保整个以太坊生态系统的兼容性。他在Github上发布了该提案，该提案是开发人员存储和共享代码的平台。 Vogelstellar解释了为什么如果您想听到更多的话，在DevCon3的一次采访中，这一过程在推动创新中如此重要。

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.

该提案在2017年底得到认可，并在以太坊改善提案20（EIP-20）中正式化，该提案是由以太坊共同创始人Vogelstellar和Vitalik Buterin撰写的，可以在此处查看。

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年度的初始硬币产品（ICO）繁荣中走到了最前沿。 ICO类似于首次公开发行（IPO），但对于新的加密货币而不是股票。在此期间发布的大多数令牌都在以太坊网络上，而ERC-20成为行业标准。现在有超过3.5万ERC-20资产。

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代币在以太坊网络上提供了广泛的目的。它们可以代表数字货币，在治理系统中的投票权，甚至代表现实世界中的现实资产（例如房地产或黄金）的标记版本。这些令牌由智能合约提供动力，智能合约是存储在以太坊区块链上的自我执行的代码线。当满足某些预定条件时，这些合同会自动执行特定的功能，例如处理交易。

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.

当开发人员创建ERC-20代币时，他们写了一份智能合约，以定义令牌的名称，符号，供应以及交易应如何工作。合同必须实施标准ERC-20功能。例如，BalanceOf（）允许用户在转移（）指示合同将令牌从一个钱包发送到另一个钱包时检查其余额。通常，这将需要对以太坊上使用的编码语言有深入的了解，但是今天，有些平台可以帮助您更轻松地创建令牌。

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

这种标准化通过使开发人员能够构建可互操作的钱包，分散交易所，贷款应用程序和其他Defi平台而无需自定义编码，从而推动了Defi的快速增长。结果，用户可以轻松交易，借贷，股份
