I built an Ethereum version of Reddit r/place called https://etherdoek.com. All Ethereum art projects so far rely on storing data off chain. I wanted to show that it's possible to store everything on Ethereum. That way blockchain qualities like censorship resistance are preserved. The canvas will exist as long as Ethereum.

The difference with Thousand Ether Homepage is that they store images off chain. Etherdoek stores pixel information (hex values) on the Ethereum blockchain itself, including as events all pixel changes. All the blue question marks on Thousand Ether Homepage are lost images.

I've added a few Python scripts for easier interaction but totally agree that for now putting images on Etherdoek is a pain.

Hi all, creator of Etherdoek here. I had this idea for a while and the corona lockdown was a good excuse to work on it. I’ve also written an article about tokens and art and when I think it makes sense to put things on the blockchain: https://www.etherdoek.com/tokens_and_art.

In short, Etherdoek is a 1,000 by 1,000 pixel canvas. Pixels are sold through a smart contract. The buyer sets the pixel color (hex value, 3 bytes) and gets an ERC-721 token which corresponds to her pixel. Pixel tokens can be traded like any other ERC-721 token. Through the same smart contract any owner of a pixel token can change the color of the corresponding pixel.

The canvas will exist as long as Ethereum. Ethereum contains the full state of the image and changes are saved forever as events. It’s censorship resistant and does not depend on any data being stored outside of the blockchain.
