EIPs are improvement proposals for Ethereum that describe changes that can be made to the protocol to improve its efficiency, security, scalability, among other aspects. These proposals may refer to smart contract programming, network improvements, tokens, and other topics.
On the other hand, standards in Ethereum focus on the creation and improvement of norms for tokens on the network. ERCs (Ethereum Request for Comment) are an example of standards that establish the rules for all tokens in Ethereum to have specific and predictable behavior. The ERC-20 standard, in particular, is one of the most popular and widely adopted in Ethereum. This standard defines the basic functions that a token on the Ethereum network should have, such as account balance, token transfers, and balance inquiries.
The Ethereum network is built on a foundation of improvements and standards that define how users can interact with the blockchain and its tokens. By following these standards, developers can create tokens that are compatible and easily integrate with other applications and services on the Ethereum network, which helps to promote adoption and innovation on the network.
NFTs (Non-Fungible Tokens) are a unique form of token that cannot be replaced by other tokens and are used to represent unique digital assets. The ERC-721 is the standard for creating non-fungible tokens on the Ethereum network. This standard defines the basic characteristics and functions that a non-fungible token should have, such as the ability to be unique, transferable and possess a unique identification.
The creation of non-fungible tokens based on the ERC-721 standard allows for compatibility and easy integration with other applications and services on Ethereum.
Meanwhile, Soulbound Tokens (SBTs) are a proposal for a unique and specific token for each user on Ethereum, which is "bound to the soul" of the owner and cannot be transferred to other users. SBTs are currently in a phase of development and exploration within the Ethereum community and do not yet have an officially defined standard.
Token standards in Ethereum are crucial to allow tokens to be compatible and easily integrated with other applications and services on the network. The ERC-721 standard for NFTs is one of the most popular and widely adopted, while the proposal for SBTs is a developing technology that is in the exploration phase within the Ethereum community. Both standards demonstrate the continuous evolution and development of blockchain technology on Ethereum and how it can be used to represent and transfer unique digital assets.
