EIPs vs. ERCs

Among the different categories of EIPs, Ethereum Request for Comment (ERC) stands out as a key component, encompassing standards and conventions that shape various aspects of Ethereum's functionality and applications.

An Ethereum Request for Comment (ERC) refers to the original draft proposal written by developers, later refined as an EIP. ERCs primarily focus on different application levels and conventions within the Ethereum ecosystem. Notable examples include token standards such as ERC-20, which defines the interface for fungible tokens, and URI schemes, library/package formats (EIP-82), and wallet formats.

If an ERC gains consensus within the Ethereum community, it becomes a standard that automates the rules outlined in the ERC through a related smart contract. This standardization process ensures interoperability between different applications and services built on Ethereum, creating a more cohesive and functional ecosystem.

Standards Track EIPs cover a broad range of changes that impact most or all Ethereum implementations. These proposals can be further categorized into subcategories, including core, networking, interface, and ERC. The distinction lies in where these proposals are deployed and the level of consensus required for adoption. The following is a breakdown of the Standard Track EIPs:

Core EIP

Core EIPs are deployed at the protocol level and necessitate broad consensus within the Ethereum community. For such EIPs to be considered successful, widespread adoption is essential, requiring all nodes to upgrade to the new protocol version.

Core EIPs play a critical role in defining the fundamental rules and protocols that govern the entire Ethereum network. These proposals often involve changes to the consensus mechanism, block validation rules, or core data structures. Due to their fundamental nature, core EIPs undergo the most rigorous review process and require coordination across all client implementations.

Examples of core EIPs include changes to the gas pricing mechanism, modifications to the block reward structure, and improvements to the consensus algorithm. The implementation of core EIPs typically requires network-wide hard forks to ensure all participants operate under the new rules.

Networking EIPs

Networking EIPs focus on improvements related to network communication and peer-to-peer protocols. These proposals aim to enhance the efficiency, scalability, and security of the Ethereum network's communication infrastructure.

Networking EIPs address issues such as peer discovery mechanisms, data propagation methods, and network protocol optimizations. By improving how nodes communicate and share information, these EIPs contribute to faster block propagation, reduced bandwidth requirements, and more resilient network connectivity.

These proposals are essential for maintaining a healthy and efficient peer-to-peer network, especially as the number of nodes and transaction volume continues to grow.

Interface EIP

Interface EIPs primarily concentrate on user experience and the development of user-facing interfaces. These proposals seek to improve the usability, accessibility, and interoperability of Ethereum-based applications, making it easier for users to interact with the blockchain.
