i made a blockchain app for fun. you can hold and send funds. you can make posts which can be multiple types of data whether it is comments or list of comments. you can also upload files.
instead of having one big network, anyone can start their own blockchain. the funds that get raised in their chain can be transfer out or in the chain.

i plan to post everything i can along with the github page once i finish the website for this project.
i am also air dropping coins so if you guys want some coins leave the email on this email list.
