Show HN: Etherdoek, an Ethereum version of Reddit r/place

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.

This already exists:

HN thread:

Not sure if that also,supported re-trading/coloring of the pixel. That could be a nice touch or very against the idea of the others which meant to be "forever". Not needing a special browser is nice.

I might miss it but it seems this page assigns me a single pixel, or one pixel at a time where I can control x,y? The power of the others lies in being able to buy multiple pixels in a controlled fashion and having an easy way to add your logo (jpeg/png/...).

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.
