Wow compare to EGOLD this is really hard mining work.

yeah finding a mint is waaaaayyy harder for ELEMS lol

21 accounts at the moment are holding ELEMS

nxt.mint.threadPoolSize > 1 bring a IndexOutOfBound-Error to me ... why?

with EGOLD it's no problem to set more then 1 thread

value = 0 doesn't work too

If you keep unitsPerMint=0.01 you will pay 1nxt fee per 0.01ELEMs that you mint. I think that ELEMS has the potential to maintain a high price, and when more people join and the difficulty will be higher and coin distribution wider , 0.01ELEMS will worth more than 1nxt but maybe you can try first to alter unitsPerMint between 1 and 0.5 (you will pay 1nxt for 0.5 ELEMS etc). At the end the community will drive the price and hopefully we will keep a big NXT/ELEMS ratio.

Klokan you are not so new to nxt. Your account has already 28.8 nxt.
I just sent you another 7nxt in order to start mint your first ELEMS

But I'm quite new to minting process (as we all are, I suppose) ;-). Many thanx for that 7NXT for minting, Mr. Elements ;-)

I find it difficult to mint using my CPU. The first coin was probably the easiest. The next consecutive coins are hard to mint. This is getting serious. $:-\$

Quote from: Djinou94 on January 11, 2015, 03:45:47 pm

I don't undestand how to mine

Part 1 - Prepare the Client

1. Download the latest client version from here: hxxps://nxtforum.org/nrs-releases/nrs-v1-4-7-1/ (sorry, still can't post links)
2. Unzip the folder
3. You need to download the blockchain.
4. Navigate to "nxt" in your newly unzipp folder
5. Run run.bat (assuming that you have a windows system)
6. After that a new folder called "nxt_db" will appear.
7. If you have already the database somewhere else from a previous version of nxt , close the console window and copy/paste the files inside "nxt_db"

Part 2 - Create an account

If you don't have an account or you want to create a new one just for minting purposes:

1. Run again run.bat
2. Double click "NXT_Wallet" (internet shortcut)
2. Generate a new passphrase

Part 3 - Minting

1. Locate "nxt/conf" folder
2. You will find two files inside
3. Copy paste "nxt-default.properties" inside the folder and rename the new generated file "nxt.properties"
3. Open "default.properties" using a text editor like sublimetext or notepad++ (you can use notepad also but the result is going to be ugly)
4. Find and change the below parameters (at the end of the file)

nxt.mint.serverAddress=localhost
nxt.mint.currencyCode=ELEMS
nxt.mint.secretPhrase=your passphrase
nxt.mint.unitsPerMint=1
(this means, you will pay 1nxt fee for each ELEMS that you will mint, you can change this accordingly, however greater number increase the difficulty to mint a coin, smaller number decrease the difficulty but you will pay more fees, check "Additional Best practices" below)
nxt.mint.threadPoolSize=1
nxt.mint.initialNonce=0
nxt.mint.isSubmitted=true

5. Save the file
6. Go back in the "nxt" folder and run "mint.bat"
7. A new console window open, if everything is correct after the initialization you will see "Mint worker started"
8. Happy minting

Try and if you need extra help post here.

First of all we are very lucky that nxt developers create MS and we have the chance to experiment with it. Our coin is secured with the Nxt blockchain and can be exchangeable with "exchange Booth", so we will put our time and effort to find use cases.

With no GPU and ASIC mining at the moment, our coin is a chance for new users and off-course existing ones to experiment with the minting procedure. The early adoption will be more fair like BTC or LTC some years ago. Fair and wider adoption is one aspect of a coin value. Another one is to find ways to spend the coins that you own. There are people willing to spend computer power to generate coins, we need to have also people willing to buy these coins because they are useful to them. The Elements team will introduce ways to spend ELEMS for useful products and services. Nxt will also profit for ELEMS utilization. All these features and more is our plans for the near future.

Imagine that there are only 114.3342 ELEMS minted at the moment. So you hold a little less than 3% of the distribution. Another problem is the bug in Scrypt algo that we cannot use all your threads of your processor. But at the same time it is up to us to keep the value of the coin high and coin 3 coins will store enough value for you in the near future. Also something else that can be useful is to make a list of processors and hash rates so anyone can have a comparison.

Someone for example just bought 1ELEMS for 350nxt. And this is only the start.

The Mint worker stops at "INFO: Mint worker" then nothing since then, it's been about 20 minutes.

My conf is the following :

Quote

#### MINT ####

# Address of the NXT server to which the mint worker submits its transactions (default: localhost)
nxt.mint.serverAddress=localhost

# Specify a mintable currency code
nxt.mint.currencyCode=ELEMS

# Secret phrase for the minting account, this secret phrase is sent to the host specified by
# nxt.mint.serverAddress therefore do not specify secret phrase of an account with lots of funds
nxt.mint.secretPhrase=my secret pass

# Number of units to mint per transaction
# The minting difficulty grows linearly with the number of units per mint
nxt.mint.unitsPerMint=1

# The initial nonce used for minting
# Set to 0 to start with a random nonce
nxt.mint.initialNonce=0

# Number of concurrency threads used for minting
# Set to 0 allocate one thread per processor core
nxt.mint.threadPoolSize=1

# When set to false mint transactions are not submitted when a hash is solved.
# Set this value to true to perform actual minting

Is there a problem with it ?

nah sometimes it just takes a long time to get anything. Even the notification to say at "pool-1-thread-1" takes a while to come out.
