I want to create a contract on Ethereum to store data. I'm beginner on this domain...Do we have a better solution?
In this post, someone tell me to download a plugin. This is one way to do it, but I want to insert data in a block-chain with python (or other language).
I don't know where to start ... download Ethereum? Create an account?
Does it incur any cost? How much?
If contracts can be update, can I use Ethereum contract to prove work?
