On-Chain NFT How to store a pixel image on the ethereum blockchain

Question

I just recently finished an art project and am looking for a way to store the data on-chain. Like deadbeef for example. The source of my generated 6x6 pixel images are pictures, so I cannot recreate them by code. I guess I have to store their raw data in some form on-chain.

As I am new to blockchain, I’m aware that tokens are stored on the chain. I have minted some artworks on hen and opensea, but I generally do not understand how it all works in the background. Can anyone please recommend some well explained tutorials or articles on this topic?

Thank you!

Answer 1

The images are usually not stored in the chain and rather, it decreases the transaction costs. A JSON file can be the creation of output once the images are uploaded to ipfs through the use of pinata. This helps in marking it and uploading the image on pinata. Additionally, the tokenURI is nothing but the same JSON file as mentioned in the example below:-

TokenURI=ipfs://<json_file_hash>"

Then in your JSON file:

{ "image": "<image_file_hash>" }
