Understand what is Ethereum Request for Comment in one article?
Ethereum Request for Comments (ERCs) standardize smart contracts, allowing for consistent behavior, interoperability, and community-reviewed reliability in the Ethereum ecosystem.

Understanding Ethereum Request for Comment (ERC)
What is an ERC?
Ethereum Requests for Comment (ERCs) are standards that formalize the relationship between Ethereum smart contracts and external systems. They provide a common set of rules and guidelines for developers to create and use contracts that are compatible with each other.
How ERCs Work
ERCs define specific functional requirements, such as:
- Interface definitions: Describing the functions and data types a contract must implement.
- Event definitions: Specifying the events that a contract can emit.
- Error codes: Defining the error conditions that a contract can raise.
Types of ERCs
There are various types of ERCs, each serving a specific purpose:
- Core ERCs: Fundamental standards that form the core of the Ethereum ecosystem, such as ERC-20 (tokens) and ERC-721 (non-fungible tokens).
- Token and Contract Standards: ERCs that define functionality related to tokens, crowdsales, and smart contracts.
- Meta-Standards: ERCs that provide general guidelines and best practices for contract development.
Benefits of ERCs
ERCs offer several benefits for developers and users:
- Standardization: They promote consistent and predictable behavior of contracts, making it easier to develop and interact with them.
- Interoperability: ERCs facilitate communication and interaction between different contracts and systems.
- Community Review: ERCs undergo a rigorous review process by the Ethereum community, ensuring their quality and reliability.
Examples of Notable ERCs
Some notable ERCs include:
- ERC-20: Defines the functionality of fungible tokens, such as the standard for transferring, approving, and querying balances.
- ERC-721: Defines the functionality of non-fungible tokens, with unique identifiers and methods for ownership management.
- ERC-1155: Extends ERC-20 and ERC-721 to support batch transfers and both fungible and non-fungible items.
Conclusion
Ethereum Requests for Comment are essential standards that define how smart contracts interact with each other and the Ethereum ecosystem. They promote standardization, interoperability, and community review, providing developers with a foundation for building reliable and compatible contracts.

The Lightning Network is a second-layer solution built on top of the Bitcoin blockchain to enhance its scalability and transaction speed. It operates as an off-chain network of payment channels that allow users to conduct multiple transactions without the need to commit each transaction to the Bitcoin blockchain. This significantly reduces the load on t...

Apr 29,2025 at 10:43am
An oracle in the context of blockchain technology refers to a service or mechanism that acts as a bridge between the blockchain and external data sources. It is essential because blockchains are inherently isolated systems that cannot access external data directly. By providing this connection, oracles enable smart contracts to execute based on real-wor...

Zero-knowledge proof (ZKP) is a cryptographic method that allows one party to prove to another that a given statement is true, without conveying any additional information apart from the fact that the statement is indeed true. This concept, which emerged from the field of theoretical computer science in the 1980s, has found significant applications in t...
