Hi :D
ha anyone tried to create a token using the code on ethereum website and the function MyToken line is spitting out an error?
@imugera Send the code and I'll take a look and see if I can track down the error
@botanki this is the error code No visibility specified. Defaulting to "public".
function MyToken(uint256 initialSupply) {
Spanning multiple lines.

Functions and variables have a visibility, an "Access Modifier":


Access modifiers
public - Accessible from this contract, inherited contracts and externally
private - Accessible only from this contract
internal - Accessible only from this contract and contracts inheriting from it
external - Cannot be accessed internally, only externally. Recommended to reduce gas. Access internally with this.f.

You should get used to assigning access modifiers to your functions, atleast, to get that error to go away.

makes a lot of sense. Thanks a lot!
Now if you write: function MyToken(uint256 initialSupply) public { } it will disappear. If you do not want your function (in this case, the constructor) to be accessible by everyone else, then you can for example make it private
I can recommend you this readMe on GitHub which gives a short explanation to all functions in Solidity: https://github.com/manojpramesh/solidity-cheatsheet
I have a new idea for creating digital currency. Anyone help me to create a new digital currency?

        members[i] = members[i+1];
    delete members[members.length-1];
wtf is this?
hi how to create my own cryptocurrency
Varun Agrawal
totalSupply = initialSupply 10 * uint256(decimals);
totalSupply = initialSupply * 10 ** uint256(decimals);
who on earth wrote this line?
@gurpk07 You can check the OpenZeppelin repo for a quick implementation of how to create your own cryptocurrency
@padilla360 yes.. how can i help?
What I'm thinking of is what everyone needs.
First of all, what should I know to create a new digital currency?
How much money is needed?
How long will it take?
What are the main conditions for creating a new digital currency?
What are your conditions for creating a new digital currency?
How many people and with what expertise will we need?
Generally you would need to 1)understand blockchain
2) learn solidity
3) Get a good ide/platform for development example : dokin (nuclux.io)
As for time and money it varies alot
What infrastructure will be needed to create a new digital currency?
I have heard that today, the creation of a digital currency on the
platform of the Austrian is so simple as setting up a new site with
Of course, I do not have $ 100,000, but I'll give you 5 million new
digital currency tokens, which we'll be making with the help of the
start-up. What do you think?
@all hi all! One question regarding the blockchain tehcnology itself (not only Ethereum): Would it be possible join point one blockchain to another? Using the Hash ID of the blocks from BC1 to point at info in blocks from blockchain BC2 ?

Hey guys, has anyone had experience with this tutorial? https://www.udemy.com/blockchain-developer/

It's on blockgeeks, and I was thinking about going through it before ETHDenver hackathon. Maybe you guys know something better and more concise to get one's Ethereum gears going?

Hey guys. If I want to create a crowdfunded token, do I absolutely need to have the shareholder association created?
So my goal is just to have a fixed amount of token created and automatic distribution of the token through crowdsale (fixed time). There's no other functionality needed.
anyone recommend a service to create an alt-coin under Ethereum as a service?
Hey all, keen to get some advice on how to properly manage releasing coin over a number mints. We want to keep initial supply low and 1M and then create another 1M at 98% of coin sales, then 2M and so on. Any ideas on how best to approach this?
