The universal Ethereum platform has made it much easier for developers to create new tokens quickly and easily. However, as the number of tokens has grown, it has become more difficult to distinguish them and keep track of their functionalities. This caused significant disruption by requiring developers to learn new programming languages to comprehend the technology and apply it to their platforms. Furthermore, each language is distinct from the others, making effective token management difficult. This became an even more pressing issue as the number of tokens increased on a daily basis.
To address this problem, Ethereum introduced a standardization system for tokens in 2015. This standardization helped bring tokens into a more consistent form, which contributed significantly to the platform's popularity. Ethereum remains the most popular platform for creating tokens, and it doesn't have to be done from scratch. In other words, Ethereum provides the backbone on that developers can build muscle.
So In this blog post, we will dive into the world of ERC-20 tokens and explore their role in the Ethereum network. We will go over what ERC-20 tokens are, and how they work. In addition, we will examine the ERC token standards as well as the most commonly used ERC-20 tokens.
What is a Token?
Let's first discuss the fascinating word "Token"
In a crypto world, a Token is a digital asset managed by blockchain technology. A token is a digital asset or utility that can be traded and used on its blockchain by its owners for a variety of uses, such as to speed up transactions, incentivize user behavior, or signify ownership of a piece of property or an item. They can also be traded on cryptocurrency exchanges, and their value is determined by market demand and supply.
Moreover, we can create our Tokens on different blockchain networks such as Ethereum, Binance Smart Chain, and others, each with its own unique features and capabilities.
A strong standard must be able to handle such a potent Ethereum feature, right? That is exactly how the ERC Token Standards come into play. With the use of this standard, programmers can create token apps that can communicate with other goods and services.
What are ERC Token Standards?
ERC token standards are a set of rules and regulations that are used to determine how a digital token(asset) should work within a blockchain network. Here ERC stands for "Ethereum Request for Comments", which is a standard protocol that allows developers to create and deploy tokens that are compatible with other Ethereum-based applications and services.
These standards' objectives are very clear to the point, which is to develop a decentralized and open-source platform that adapts and changes to meet the demands of its users. With keeping these things in mind Developers may make sure that their tokens are quickly incorporated with the current Ethereum infrastructure, including wallets, exchanges, and other dApps.
An ERC is composed of several documents that comprehensively outline the proposed changes, such as a technical specification, implementation specifics, and a justification for the changes. The proposal is then accessible to everyone for discussion and can be studied and later examined by the Ethereum community before being approved or denied in the future.
There are several different ERC token standards, each with its own specific features and use cases. Some common and most used tokens are ERC-20, ERC-721, ERC-777, and ERC-1155.
ERC-20 Token Standard
The ERC-20 token standard is a set of rules and guidelines that governs the creation of digital tokens on the Ethereum blockchain. In 2015 a developer named Fabin Vogelstellar suggested this ERC-20 standard as a means of standardizing the tokens within the Ethereum blockchain's smart contracts functionality. Fabin posted the ERC proposal on its GitHub account.
The token standard was given the name ERC-20 because the submitted proposal was the twentieth comment. The Ethereum community completed its due diligence after the proposal was submitted, and it adopted the plan by 2017. Back then it was known by the name Ethereum Improvement Proposal(EIP-20), but it was then renamed to ERC-20.
For a token to be certified as ERC-20 compliant, it must agree to a set of both required and optional regulations.
These Regulations are as follows:
Token Transfer Function: Tokens must have a transfer feature that lets owners move them between addresses. This feature needs to be safe and guard against unauthorized transfers.
Total Token Supply: To avoid inflation or deflation of the token's value, the total supply of tokens should be carefully regulated. The initial supply of tokens should be specified, and if necessary, methods to modify the supply over time should be defined.
Token Metadata: For users to quickly recognize and monitor a token, token issuers should give metadata about the token, such as its name and symbol. Token owners and other stakeholders should have simple access to this metadata.
ERC-20 tokens that follow these rules can consistently interact with one another and can be easily traded on decentralized exchanges (DEXs) and used within decentralized applications (dApps) built on the Ethereum network. Besides that, the standardization has made it easier for wallet providers, exchanges, and other services to support ERC-20 tokens, resulting in their widespread adoption.
On top of this, ERC-20 tokens are also fungible, meaning that each unit of the token is identical and interchangeable, like cash.
Which are the most popular and well-known ERC-20 tokens???
So here are some well-known ERC-20 token in the crypto world that follows the ERC-20 standard:
Binance(BNB)
Chainlink(LINK)
Tether(USDT)
Uniswap(UNI)
Aave(AAVE)
DAI Stablecoin (DAI)
ApeCoin (APE)
Goals of these ERC-20 tokens??
Here are some of the important goals they serve in the crypto world:
To be used as a medium of exchange within Ethereum-based decentralized applications (dApps).
To allow for the simple and secure transfer of value between users.
To provide developers with a standardized method for creating and deploying new tokens on the Ethereum network.
To make fundraising easier by using initial coin offerings (ICOs) or token sales.
To enable the development of loyalty or rewards programs within dApps or other applications.
To establish a framework for community governance and decision-making.
To create digital assets that are representations of physical assets such as real estate or artwork.
To enable low-fee, fast-transaction cross-border payments and remittances.
To encourage specific behaviors or actions within a dApp or other system.
Summary
The Ethereum blockchain is governed by a set of standards and guidelines known as ERC20, which apply to all Ethereum tokens. Basic Attention Tokens (BAT), Shiba Inu (SHIB), and Crypto.com Coin are all examples of ERC20 tokens that are widely used as utility tokens (CRO).
It is critical to recognize that ERC-20 provides a set of standards for the widely used Ethereum network. In some ways, this helps the crypto space's self-management and long-term efficiency.
