I want to start my own cryptocurrency using the same infrastructure as bitcoin. The only difference is that I want to be able to be able to set the length (difficulty) of the code the computers have to mine and be able to change it. So if its set to 100 characters its 100 length - but I should be able to change how long the length is aswell by an override which updates everyones.
I also need my own downloadable piece of software that can mine my coin and process (mycoin-mycoin transactions) and (mycoin-bitcoin) transactions. The downloadable software needs to run on windows, mac and linux on the desktop area.
There needs to be an easy way to make wallets for my coin using QR codes, urls (similar to bitcoin).
I need to mint 21,000,000 coins and make it finite.
There needs to be a way to store the coins in cold storage.
