    /* This creates an array with all balances */
    mapping (address => uint256) public balanceOf;

Source file does not specify required compiler version!Consider adding "pragma solidity ^0.4.18

Spanning multiple lines.

@TomBroomer you need add " pragma solidity ^0.4.18" at beginning of your contract.

i use this command to start ganache

ganache-cli -p 7545 -i 5777

on my local machine (16gb Ram) it works fine
but on aws (1gb Ram)
i can deploy the contract and add content to it... i can see the transaction in logs..
but when i try .call() to retreive the added content nothing happens
why it works locally and not on AWS?

@nextsense6253 Are you prepared to pay market rate for that assistance, or are you looking for someone to work for you for free?
Jan 27 2018 17:47
@nextsense6253 we have a team that have been actively creating a launch platform for new tokens.

I'm just starting. Can someone send me a link to where we start writing the code to launch a coin?
Jan 27 2018 20:27
Do I have to download Ethereum Wallet or do I launch the code somewhere on the site? Or is there a link somewhere? I'd so appreciate anyone's help
@nextsense6253 what do you charge?

@SpiritualGrace pricing depends upon your needs within your dapp and functionality of your token.

I’m looking to set up a club that issues Tokens that are set at a particular value. There will be a limited amount of tokens available ( 20,000 – 10,000 are held by the club) and each token gives the holder a % of the clubs revenue generated through its activity. The more tokens a member holds (there is a limit to the number they may have) the higher the revenue generated.
Revenue may be in the form of rewards points that may be redeemed for goods or a pre-paid visa.
The Tokens are non-refundable.
Once all tokens are taken up, a new issue (Version 2) will be issued.
Is this something that I can build using the Ethereum platform?
I will require a competent programmer – do you have contacts to programmers who understand the block chain – Fiver is too uncertain.
As Token will be non-refundable, they may however be traded. If the Tokens are regarded as being a currency within the club, as the club grows in worth, the tokens may also grow in value and be traded for cash – is my understanding correct here.
I’m new to this and not too tech savvy - Your feedback would be much appreciated. FYI - I have tried to contact Ethereum via their and it tells me 'Address Not Found'??
