The Standards of Tokens: An In-depth Analysis


With the rise of blockchain technology, tokens have become an integral part of the digital economy. Tokens serve various purposes, from facilitating transactions to representing ownership rights. However, not all tokens are created equal. In this article, we will explore the standards of tokens, focusing on the concept of “tiêu chuẩn token” in English. We will delve into the definition, types, and importance of token standards, providing valuable insights into this crucial aspect of the blockchain ecosystem.

Understanding Token Standards

Token standards refer to a set of rules and protocols that define the behavior and functionality of tokens on a blockchain network. These standards ensure interoperability, allowing tokens to be easily exchanged and utilized across different platforms and applications. One prominent token standard is the ERC-20 standard, which stands for Ethereum Request for Comments 20.

The ERC-20 Standard

The ERC-20 standard is a widely adopted token standard on the Ethereum blockchain. It defines a set of rules that tokens on the Ethereum network must follow to be considered ERC-20 compliant. These rules include functions such as transferring tokens, checking token balances, and approving token allowances.

By adhering to the ERC-20 standard, tokens can seamlessly interact with other ERC-20 compliant tokens and smart contracts. This interoperability has played a significant role in the growth of decentralized finance (DeFi) applications, as it allows for the easy integration of various tokens into DeFi protocols.

The Importance of Token Standards

Token standards play a crucial role in the blockchain ecosystem for several reasons:

  • Interoperability: Token standards ensure that tokens can be easily exchanged and utilized across different platforms and applications, fostering interoperability within the blockchain ecosystem.
  • Security: Token standards provide a framework for secure token transfers and interactions. By adhering to these standards, developers can mitigate potential vulnerabilities and ensure the safety of token holders.
  • Usability: Token standards simplify the integration of tokens into various applications and platforms. Developers can leverage existing standards to build new functionalities and services, reducing development time and costs.

Types of Token Standards

There are several token standards in existence, each serving different purposes and catering to specific use cases. Let’s explore some of the most notable token standards:

ERC-721: Non-Fungible Tokens (NFTs)

Unlike fungible tokens, non-fungible tokens (NFTs) are unique and indivisible. The ERC-721 standard, also known as the Non-Fungible Token Standard, enables the creation and management of NFTs on the Ethereum blockchain. NFTs have gained significant popularity in recent years, finding applications in digital art, collectibles, and virtual real estate.

ERC-1155: Multi-Token Standard

The ERC-1155 standard introduces a new type of token called “semi-fungible.” Semi-fungible tokens can be both indivisible and divisible, allowing for greater flexibility in representing ownership rights. This standard enables the creation of multiple tokens within a single smart contract, reducing gas costs and improving efficiency.

BEP-20: Binance Smart Chain Token Standard

BEP-20 is a token standard specifically designed for the Binance Smart Chain (BSC). It is similar to the ERC-20 standard but tailored for the BSC ecosystem. BEP-20 tokens have gained popularity due to the lower transaction fees and faster confirmation times offered by the Binance Smart Chain.

Case Studies: Token Standards in Action

Let’s explore some real-world examples of token standards in action:

Decentralized Exchanges (DEXs)

Decentralized exchanges (DEXs) have revolutionized the way tokens are traded. Platforms like Uniswap and SushiSwap leverage token standards such as ERC-20 to enable seamless token swaps directly from users’ wallets. These DEXs provide liquidity pools where users can trade tokens without the need for intermediaries.

Blockchain Games

Blockchain-based games have embraced token standards to enable the ownership and trading of in-game assets. For example, CryptoKitties, a popular blockchain game, utilizes the ERC-721 standard to represent unique digital cats that can be bought, sold, and bred by players.


1. What are the benefits of token standards?

Token standards provide benefits such as interoperability, security, and usability within the blockchain ecosystem. They ensure that tokens can be easily exchanged, offer a framework for secure transfers, and simplify the integration of tokens into various applications.

2. How do token standards contribute to the growth of DeFi?

Token standards, such as the ERC-20 standard, have played a significant role in the growth of decentralized finance (DeFi). These standards enable the easy integration of tokens into DeFi protocols, allowing for the creation of innovative financial products and services.

3. Are token standards limited to specific blockchain networks?

No, token standards are not limited to specific blockchain networks. While some standards, like ERC-20, are primarily associated with Ethereum, other networks have their own token standards. For example, the Binance Smart Chain has the BEP-20 standard.

4. Can token standards evolve over time?

Yes, token standards can evolve over time. As the blockchain ecosystem continues to mature, new standards may emerge to address specific needs and challenges. Additionally, existing standards can be updated to incorporate new functionalities and improve compatibility.

5. How can developers ensure their tokens comply with a specific standard?

Developers can ensure their tokens comply with a specific standard by following the guidelines and specifications provided by the standard’s documentation. Additionally, there are tools and libraries available that assist developers in implementing and testing their tokens against the desired standard.


Token standards are a crucial aspect of the blockchain ecosystem, providing rules and protocols that define the behavior and functionality of tokens. Standards like ERC-20, ERC-721, and BEP-20 enable interoperability, security, and usability within the blockchain ecosystem. These standards have facilitated the growth of decentralized exchanges, blockchain games, and various other applications. As the blockchain industry continues to evolve, token standards will play an increasingly important role in shaping the future of digital economies.
