@johnmott59 It really depends the exact scope your clients have asked you about. There are a lot of tutorials about how to generate tokens, so yes to your answer but my intuition says they might need more.

Thank you Chim, I see you've done some tutorials, a good first step is to read over those. If I get stuck may I ask clarifying questions? I don't want to be a pest.

I developed a token but the costs are a black box to me, how much will the users of my token pay per transaction in gas and how is that determined? Will you pay more gas depending on the number of tokens you are going to send or do you pay a constant fee regardless of the number of tokens you will send? Every transaction with the token I created right now cost around 0.001 ETH which is around $2.50 right now. If ETH becomes 3x as expensive will the transactions then cost 3x as much or will the transaction fee in ETH come down in to level it out? If someone could shed light on the costs, or can share an url to a website that can, I would really appreciate it. Costs associated with using a token on ETH now and in the future are a black box right now imo

@johnmott59 Yes, there are people who have more experience than others, but everyone is also learning at the same time.

Hello, I'm new to creating contracts and am trying to deploy my first one. I created the contract by copying and pasting the code and it compiled just fine. I am getting stuck in at "Deploy". It is estimating 0.03 Eth but I obviously don't have any Eth in my wallet. I'm not sure how to obtain the Eth. I try mining them by going to the menu selection under "Develop" and I don't see anything happen. Also, I have sat through many hours of my computer downloading something, connecting to peers and what seems to be downloading millions of blocks. I would think I'd have Eth by now but there must be something I'm doing wrong. Do I need to purchase Eth somewhere? If so where and how do I then get them into my wallet?

@dkonig1234 Get parity, use a dev chain and test your contracts there itself. Or you can deploy your contract on test networks. Other than main ethereum network, there are test networks also, where you can get ether and test your code. Other chains are ropsten, rinkeby, kovan, dev chain(this one runs locally)

I'm on the test-net but when I select mine ether nothing happens
can I buy them?
Ayushya Chitransh
@AyushyaChitransh
Sep 08 2017 06:17
Which test-net are you using? Every testnet has its own mechanism of granting ether to users.

The one at ehereum wallet
I am learning from ethereum.org
they have a wallet you download
then I went to the test-net account and created a contract
but to deploy it asks me for Eth I don't have.
Theres an option that says Start Mining but when I select it nothing happens

I'm trying to look up some of the test nets you mentioned and I'm not sure how I would go about testing the code I got from Ethereum.org.

@AyushyaChitransh
Sep 08 2017 06:27
I too haven't used the codes from ethereum.org and I dont know how to connect to other chains using the code ethereum provided. I have used geth and parity till now.

@dkonig1234
Sep 08 2017 06:28
where can I read about that or get the code to test a simple coin launch?
I mean get and parity. Any specific site?

By the way, thanks for the help.

@AyushyaChitransh

Welcome :smile: And by the way, get is a verb and geth is an Ethereum CLI client ;)

is this the wallet site?
How many different tokens have you launched?
Ayushya Chitransh
@AyushyaChitransh
Sep 08 2017 06:40
I had created the node and for demonstration purpose, we deployed a token on it. It was done on private chain.
Token deployment is not difficult, you just have to have a node connected to the testnet. If that is ready, you can deploy easily.

I just read a bit. I'm on a mac, I don't know if I can do that here, can I? It seems I need to create that node on a unix server. Am I wrong for assuming that?
Ayushya Chitransh
@AyushyaChitransh
Sep 08 2017 06:44
@dkonig1234 I would happily say that you are wrong in assuming that. You can create a node on mac also. Install pariity, run the client by connecting to dev chain, and deploy your contracts or tokens

Thanks
I set up my node

Now you can start wallet using parity --chain dev and browse your wallet at http://localhost:8180/#/home

I'm obviously a bit lost but I have what already seems to be a parity wallet
it is telling me not connected to any peers most likely a connection problem but I have no idea how to fix that
or how to mine for eth or gas
Ayushya Chitransh
@AyushyaChitransh
Sep 08 2017 07:47
You don't need to mine for eth or gas, you can simply specify that you want this much ether in your account. Take a look at https://github.com/paritytech/parity/wiki/Demo-PoA-tutorial

I tried to deploy a contract and now my computer seems to be stuck in a loop . I here the computer running and I can't stop parity

@AyushyaChitransh
Sep 08 2017 07:52
ctrl+c in the t4erminal from where you started parity

Sep 08 2017 07:55
i didn't use the terminal. I used an application that opened in a website http://127.0.0.1:8180/#/home
I can't stop this thing
do you know how to find out what is running in the background on a mac?

I use pkill parity on Ubuntu.

Hello, I am new here, am a full stack web developer, trying to get my hands dirty in ethereum also.
Is there any tutorial to start?

@techansaari ethereum101 is a good place to start with. The course ethereum101 is available on udemy

@dkonig1234 In a terminal window "ps -ef | grep -i parity" or "ps -ef|grep -i geth" depending on what client you use.

I'm having a problem with accessing the public variable of my Custom Token. What I'm trying to do here is to get the variable decimals so I can multiply 10 raised to the number of decimals for the Crowdsale transfer of reward token. Any thoughts on this? Please
