# How to decode NFT file from ERC-721 using etherscan A quick how to magic behind NFTs.

ethereum.org Standards post

Edited version of the Ethereum Standards post Title: Ethereum Standards Introduction The Ethereum ecosystem have it's own improvement process which is using standards - improvement proposals to update the protocol. These standards are Ethereum Improvement Proposals using shortcut EIPs. EIPs are the primary mechanisms for proposing new features, for collecting community technical input on an issue, and for documenting the design decisions that have gone into Ethereum. They have it's own governance process through which EIPs go through in order to be apart of the protocol update. This governance process is described in EIP-1, where you can find graph of the full EIP governance workflow. EIP Types We differentiate EIPs based on their types. All EIPs go through the same EIP process, at the time of writing this post. This may likely change in the future.
