The Genesis of Token Standards

The development of token standards like BEP-20 and ERC-20 didn’t happen in isolation; they are part of a broader evolution in the world of blockchain and cryptocurrency. These standards emerged to address the need for interoperability, compatibility, and ease of use within their respective ecosystems.

BEP-20 Tokens on Binance Smart Chain

Binance Smart Chain (BSC) was introduced by Binance, one of the largest cryptocurrency exchanges globally, as a means to offer users a more efficient and cost-effective platform for building and using decentralized applications (DApps). BSC was conceived as a parallel chain to Binance Chain, which primarily focused on fast and low-fee transactions. While Binance Chain was ideal for simple transfers and trading, Binance recognized the growing demand for smart contract functionality and the ability to create a wide range of tokens with advanced features.

This is where BEP-20 tokens come into play. BEP-20 tokens are native to Binance Smart Chain and are designed to be fully compatible with projects that already use the BEP-2 standard on Binance Chain. BEP-2 tokens were primarily used for simple asset transfer, while BEP-20 tokens allow for more complex use cases within the BSC ecosystem, such as creating DeFi applications, NFTs, and other smart contract-based solutions. The introduction of BEP-20 tokens thus extended the capabilities of the Binance ecosystem, making it more versatile and appealing to developers and users alike.

ERC-20 Tokens on Ethereum

Ethereum, which was introduced in 2015 by Vitalik Buterin, quickly emerged as a pioneering platform for decentralized applications and smart contracts. As the Ethereum ecosystem grew, so did the need for a standardized token format that could ensure seamless interaction between different tokens and DApps on the Ethereum blockchain.

This led to the creation of ERC-20, which stands for “Ethereum Request for Comment 20.” ERC-20 is a set of rules and standards that specify how tokens on the Ethereum blockchain should behave. These rules encompass crucial aspects like how tokens are transferred, how transactions are approved, and how token balances are managed. The introduction of the ERC-20 standard marked a pivotal moment in the history of blockchain technology. It not only simplified the process of creating and managing tokens but also paved the way for the explosion of Initial Coin Offerings (ICOs) and decentralized applications (DApps) that we saw in the years following its release.
