Being creative on Ethereum

For a long time, I’ve wanted to dive into blockchain programming. My goal was to provide a space where users can be creative, while exploring wallets and blockchain technology without worrying about investments or risks.https://preview.redd.it/in5ln96h410f1.png?width=1666&format=png&auto=webp&s=c4931ad0974affec97004f4b3e5838c270732e75Here’s the idea in a nutshell:The canvas is infinite, with each cell holding a stack of images on the z-axis. Only the top image is visible (in 2D mode).You can place your image on the canvas by paying a small fee in ETH to each owner of an image below yours (0.0001 ETH per owner). If people place images on top of yours, they must pay a fee to you.The first image in any column gets to name that column.Every image you place becomes an NFT stored on Arweave, making your contribution visible, tradable, and traceable (including any outstanding payments).Any thoughts, suggestions, or ideas for improvement are more than welcome. I would also appreciate it if someone could identify any security issues in the contract.You can find it on defidiorama . com via /r/SideProject https://ift.tt/48XsQOI
