This standard defines the rules for creating non-fungible tokens (NFTs) on the Ethereum network. each ERC-721 token is unique and represents ownership of a specific asset. This makes ERC-721 tokens ideal for representing digital assets.

ERC-721

Is a multi-token standard on the Ethereum network that was proposed by in 2018. designed to allow for the creation of both fungible and non-fungible tokens within a single smart contract. ERC-1155 offers a powerful and flexible standard for creating a wide range of tokens on the Ethereum network.

List of ERC Ethereum  Improvements Proposals

ERC stands for (Ethereum Request for Comment) is a technical standards and specifications for implementing Tokens under Ethereum ecosystem

University of Michigan - Ann Arbor

This EIP type is the most common,  they describe about changes that affect the Ethereum implementations such as **Network Protocol**,  **rules of block transactions**, **compatibility applications**. 
For now, this type of EIP is divided in four subcategories.
- Core.
- Networking.
- Interface.
- ERC.

EIP (Standard)

As its name says, is a EIP for the core technology of Ethereum, Ethereum Network Protocol, Block, Transactions and Standard for applications. 
Its main goals is to improve the interoperability of the applications and maintain the stability of the network.

Core Ethereum Improvement Proposal

This proposals are aimed to improve **Ethereum network aspects**, such as  efficiency, speed of transactions, cost of transactions, Minting process, Ether Burning Process, security enhancing etc.

Networking Ethereum Improvement Proposal

This propose a new standard for a specific type of interface (**collection of function signatures from a smart contract**), which can be adopted by other contracts in the Ethereum ecosystem. By proposing new interface standards through EIPs, developers can help to create a more standardized and interoperable ecosystem for smart contracts on the Ethereum blockchain.
