Hi, newbie to this forum here..
Just wanted to let you know about my idea of a visual blockchain guestbook where you can upload images to the ethereum chain.
The images are of course immutable and are going to stay there for as long as the blockchain exists.
In order to prevent massive spamming of the network, space is finite and quite limited and prices for pixels are, well, sort of ridiculously high.
Anyway.. smart contract is deployed and an instance of the current frontend can be found at 55a94fa0-6066-403e-b488-fb25220ba0cd.htmlpasta.com if you wanna have a look.
It's thought to be a way of permanently leaving a mark on this new tech. Possible misuse (e.g. uploading hurtful stuff) would be likely but I suppose fees are going to prevent people from actually uploading stuff. So, in the end it may remain an idea only.
