Hello there,
How i can start creating coin? can anyone give me idea on this ? We have to code for this ? Actually i am not getting the idea in code at https://www.ethereum.org/token#understanding-the-code
If we have to code then in which programming language ? I prefer Laravel, is there anything specific code for different programming language ?

@quangnd You should terminate the installation, restart you device and try again. Before that, remember to check for system requirements.

@amirhrabiee yes you have to pay a transaction fee for deploying a contract
@amirhrabiee yes if you are on main network you need ether in your wallet
however if you are on test network you can mine your own
@mstreicher yes i found one solution
@mstreicher yes i can help

Hi. I was going through the Democracy contract tutorial.
Copypasting the Shareholder Association code rises errors about the visibility of all the functions, saying that public is needed. Is this due to something changing since when the tutorial was written? Should I simply add public to all functions? Or is something else wrong with my code?
Thanks

this is so basic i guess, if you wanna introduce a blockchain solution for you business i don't think this is all you need. I guess now this tutorial is old

ok, comparing the congress with the shareholder model, the working congress model has all the "public" in the right place, plus some other obvious differences.
Should have checked before asking such a basic question
