Opal annonce un programme révolutionnaire de dividendes.
Los Angeles, Californie - 10 Avril, 2015 - Whit Jack - 16 Avril, 2015 -Voidlord

En plus de son ensemble unique de caractéristiques, Opal a annoncé aujourd'hui un système révolutionnaire de dividendes
simplement pour soutneir l'Opal.
Opal à annoncé le 10 avril le déploiement d'un système de génération de recettes via des sites webs , le premier étant bitsofnews.net,
les revenus générés reviendront aux utilisateurs Opal par paiements de dividendes.
C'est une incitation pour les utilisateurs à essayer la monnaie Opal, à garder leurs Opal, ou/et aussi pour  les maintenir dans leurs portefeuilles locaux et dans
un stockage déconnecté (cold storage).

Opal est structuré sans preminage, sans ICO, ou IPO, tout le financement et les dépenses sont couvertes par
l'équipe de développement. Avec cette approche (je rajouterai "surtout"), l'équipe Opal a su rester indépendante et honnête, nous désirons porter l'Opal au summum de l'innovation,
sans pour autant produire une quantité énorme de code, plutôt en axant sur une répartition plus homogène (Besoins, Programmation (code), Test, Correctif, Test, Marketing, relation presse, elearning ) et un effort continu de vulgarisation pour les débutants.

Pré-requis: Opalcoin Wallet 1.3.2.0

Traduction en cours:

"Opal Embassy,"
"This is your coin,"

10. Checking the Opal wallet Authenticity




Gemlock is a decisive tools in our security roadmap, soon, Opal user will check, directly inside his wallet if this one is the good one (the last and certified one) and if it is not corrupted !

How it works ?
by comparing the SHA1 checksums of your Opal wallet and the official Opal wallet.

Does it work ?
yes, but it is not yet automated.

Let's get checking our last wallet, (here is the tuto):

For WINDOWS users:

1. Go to C: create a new folder and name it FCIV
2. Download the File Checksum Integrity verifier : http://download.microsoft.com/download/c/f/4/cf454ae0-a4bb-4123-8333-a1b6737712f7/Windows-KB841290-x86-ENU.exe
3. In the file download box, click Save and save the file in the FCIV folder
4. Go to your FCIV folder and double-click on Windows-KB841290-x86-ENU.exe  then click ok
5. Click ok to extract the file (if asked, extract the file in the FCIV folder),
6. Double click fciv.exe to run it.
7. Click start ,on the search field type:
Press enter, then click cmd.exe
8. On this black command prompt,
type
Press Enter

9. Download your favorite wallet on www.opal-coin.com at the Download Wallets.

10. Type (and replace the .zip file with the wallet you downloaded, as there are 3 different wallets).
the SHA1 checksum is the 40 numbers and letters, after File Checksum Integrity Verifier version 2.05,
example: 4c56186623bbaa7c2fea980b042270beafd3b53f c:\the full path\where you downloaded\Opalcoin-Qt-exchange.zip

11. Now, type:
And press Enter
it will displays your DNS sometime we encounter surprise here so you can check if they are yours, or if you have a box: if they are those of your ISP, type "Your ISP name DNS" in google to know them, and... anyway we need to type it

12. Type: Press Enter

13. Type: Press Enter
This order displays the genuine Opalcoin SHA1 checksums (the 40 numbers and letters).

14. Compare this guenuine SHA1 with the checksum fciv.exe gave you: they MUST be the same.
(beware to check the SHA1 of the good wallet as there are three Opalcoin client, to check it, just look at the name of your Opalcoin-Qt-Folder. Now in the command prompt look at the one which match with your Opalcoin-Qt)

 If the SHA1s are not the same: Close your wallet, save the wallet.dat in a easy retrievable folder (but not into your Opalcoin-Qt folder and not into : C:\Users\YourUserName\Appdata\Roaming\Opalcoin),
go to C:\Users\YourUserName\Appdata\Roaming\ and delete the folder Opalcoin, go to your Opalcoin-Qt folder you use to launch your wallet, delete the Opalcoin-Qt folder.

Type:
Press Enter to quit the nslookup utility.

Go to www.opal-coin.com and click wallet download, choose the walllet you need.

Now it is simple and cool, if you want to test again your last download from this simili-trusted pseudo-true opal-coin.com  (maybe you were not on the right official website )

Type (and replace the .zip file with the wallet you downloaded, as there are 3 different wallets)
fciv.exe -sha1 c:\the full path\where you downloaded\Opalcoin-Qt-exchange.zip
Enter, check.

If the SHA1s are the same: Well done you have a certified official Opal wallet !
 
You can now run it, let it sync, (it is quite long : 2 to several hours) and close it.
Go to C:\Users\YourUserName\Appdata\Roaming\Opalcoin
and put your saved wallet.dat into the folder. now start again your wallet: and stake cool !


For LINUX users:

1. Start a shell / terminal, i.e. a text based command line utility

2. Go to the directory to which you downloaded the wallet software by typing the following command to the terminal, followed by enter, replacing “ /path/to/download folder ” by the actual location of the folder where you downloaded the wallet software :

3. Type the following command to the terminal window, followed by enter, replacing “ Opal-Qt-opaque.zip ” with the name of the file you downloaded: The sha1sum command outputs a line similar to this: 3a099ff6e8831885b00431bee693ea40b3ff9e39" Opal-Qt-opaque.zip Take note of the random-looking 40 characters string. It is the SHA1 checksum of the file you have downloaded. Now compare it to the checksum provided by the DNS system at step 7.

4. Start the DNS lookup utility by typing:
followed by enter:

5. At the nslookup utility prompt (>), type the below command, followed by enter:


6. Now type the address provided by the wallet developers to the nslookup utility prompt, followed by enter:
Take note of the 40 characters SHA1 checksums returned: checksums.opal-coin.com text = "Opal-Qt-opaque.zip 3a099ff6e8831885b00431bee693ea40b3ff9e39"

7. Compare the SHA1 checksum created at step 3 to the one provided for the same file by the DNS service at step 6. If checksums are identical : the wallet file you downloaded is genuine. If the checksums are different, make sure the version of the wallet  you have downloaded is the latest one, and repeat all of the above steps. If the checksums are different after couple of hours have passed, please contact the Opal developers for advice.


For MAC users:

1. Open a Terminal (located in: /Applications/Utilities).
2. InsideTerminal prompt, type:
Press Enter

It dipslays the SHA1 checksum you will have to compare: 40 numbers and letters, here in red:
SHA1(/Your_full/path_to_file/Opaque-Final-Mac.zip) 3eb807b340d4e57aa79bb5422b94d556888bba60
with the SHA1 checksum of the official and certified opal wallets in the nslookup utility:

3.Type nslookup
Press Enter

4. After (>) type:
Press Enter

5. Type:
Press Enter

6. Compare the SHA1 checksum returned (still 40 numbers and letters), here in red with your wallet checksum, above:
something like: checksums.opal-coin.com text = "Opaque-Final-Mac.zip 3eb807b340d4e57aa79bb5422b94d556888bba60"

7.Type:
Press Enter to quit the nslookup utility.

If SHA1 checksums are the same, it means the wallet software file you downloaded is genuine. If the checksums are different, close your wallet, save the wallet.dat in another well known folder. then uninstall your Opalcoin-QT and download the latest version at www.opal-coin.com

Obviously, you can now quickly check your brand new latest download:
in the terminal type:
Press Enter and compare with the Opaque-Final-Mac.zip checksum of your last nslookup. if it is still different, call a developper on IRC : http://webchat.freenode.net/ channel : #opalcoin

If the SHA1s are the same: Well done you have a certified official Opal wallet !

The next step into security is to automate these processes, stay tuned ...

(P.S: thanks to Jyri from altcoin.center for the linux tutorial)
(P.S #2: the checksums written here are not real, these are just examples)

Hi choochimil, Yes we don't see beginners as newbies or noobs, we only see early adopters, and early adopters are not all tech savvy: reason of this thread.

Hi Truther,

Yes, bring us back with your good ideas and see you in May !

For those who want to buy, there is a phishing in progress on the Google query: poloniex,
in Europe, google returns in first place: *.poioniex.com
                          the right URL is     *.poloniex.com
(URL squatting)
ip: 50.62.160.65



good day everyone,

Nothing more to add.


Me neither

In fact Mario012 and Lumeire, We don't want to speak too quickly anymore, specially about main development (and main future one) before being 100% sure.

Yes, up to 0.00002200, these are very good prices.
i bought 60K this last week end, stopped at 2300 my real world needs funds too
i hope the windows will be still open for my next ODB (Opal dedicated bankroll)

Thanks Fontline,

at the embassy, you will be like at home !

Tshirts in progress (here it is the #3 design)
Kisstee prototype organic tshirts ordered (Black, Red, Ultramarine, White)


Tot: Totally Organic Tshirt "Kisstee serie"
100% Pure Organic Cotton & Gold.
Your skin sanctuary, titled, numbered, certified.
Plus you will know the secrets of Tots.

By the way if someone want to work in a great nodes of cryptocurrency pionneers:
(Opal, Nxt, BTCD, Fibre, Vericoin...)

you could post at http://jobs.supernet.org
We Work SuperNET is a job board and community space for users of the SuperNET. This site provides a complete listing of positions requiring the SuperNET skill set, as well as to profiles for meteor developers experts for hire.

(you will find infos to get invited on slack, by clicking the address above)

  Nobody wants to sell at your price because prices are low, a good point to buy at a little higher price than expected or to wait the hope of more cheapest prices (scarce) !

at the end it is all about your choice Mario012.

9. Mining Opals


http://altnuts.com

 For those who are new with mining, here is a complete guide:
Windows OS and AMD Graphic card.

You need to:
have decent drivers: at least 14.6:
 http://support.amd.com/en-us/download/

Download & install Microsoft.NET 4.5 framework :
 http://www.microsoft.com/fr-fr/download/details.aspx?id=42642

Download & install AMD APP SDK (for Windows 32 bits) -> http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/
Go to the second board AMD APP SDK v2.9.1 and choose the correct one (for Windows 32 or for Windows 64 bits).
download and extract sph-sgminer x11mod -> https://github.com/lasybear/sph-sgminer_x11mod (i like the 4.1.0)

Then you need to create the .conf file

Remember the extension must be seen, to be sure:

Windows 8 : Open a File Explorer window and click the "View" tab and tick "File name extensions".

Windows 7/vista : Open Windows Explorer and click the "Organize" button towards the top left. Choose "Folder and search options" from the menu. Then click the "View" tab in the window that opens, then scroll down and untick "Hide file extensions for known file types".

9.1 Mining Opals


So create a new text document with your notepad and copy/paste the following: (remember to edit oYOUR_OPAL_ADDRE55):


... Save this file as sgminer.conf in your sph-sgminer x11mod folder beware not to save it as sgminer.conf.txt.
To be sure search to folder options and  Click the View tab, and then, under Advanced settings then clear the Hide extensions for known file types check box, and then click OK.

These settings work for AMD 7970, R9 270x, R9 280x.
You should change thread-concurrency, gpu-engine, intensity (usually 13-18) and gpu-memclock values to fit your GPU habits. (if you change thread-concurrency, delete the x11modXXXXXXg2tcXXXXwXXXl4.bin file in your sph-sgminer x11mod folder).

In order to change your gpu-engine and gpu-memclock value please read https://litecoin.info/Mining_hardware_comparison, the "C" Column is for gpu-engine value and the "M" is for gpu-memclock values.

(remember that if you want to change settings when the sgminer.conf is saved you must right-click and choose edit, instead of open)

Now create another text document with your notepad and copy/paste:



-Save this file as for example Buyopal.bat in your sph-sgminer x11mod folder
 (beware not to save it as Buyopal.bat.txt)

-Create a shortcut that you cut/paste on your desktop: to start mining, just double click this Buyopal.bat shortcut ! be patient, first time it take 30 seconds to run.

For more info, please dont spam this topic and read the topic of lasybear https://bitcointalk.org/index.php?topic=623409.0

You must not have Hardware error "HW" in Sgminer, even a few, if so please read https://bitcointalk.org/index.php?topic=623409.msg7615953#msg7615953

Thanks Rcan06,

I made a little FB ad operation, in order to see who i reach with universal settings:

https://www.facebook.com/opalcommunity

name: "i want you" Op#1

duration: 2 days

first stats: 843 peoples reached
                524 women
                317 men
                   2 unknown

Age:
13 -17 : 721
18 -24 :    2
35 - 44 :   1

device:
 813 smartphones
  30 desktops

Funny isn't it ? Especially the age section.

For "i want you" Op#2 (which will start tuesday) i will tune my Audience

8. Explaining Staking


If you have opalcoin you can "stake" them, doing so you anonymously specify a verified opal amount to the Opal network and you participate to secure it. you be rewarded with a 5% annual interest extracted each day. This amount of staked coins will fluctuates, dont worry.

1. Click the little padlock on the bottom left of the wallet
2. Check "For Staking Only" and enter your password (or passphrase).



Click "Ok"

wait 30 seconds the grey arrow (next to the padlock) turns green and

Welcome,  you are a part of the Opalcoin stakers !

You're Welcome Nemanja,

 

By the way i started to rewrite the opal guide, i pasted it here:  https://bitcointalk.org/index.php?topic=1022336.0

7. Get your first free opals

To get your 100 first free opals, you just have to :

Like our Facebook page : www.facebook.com/opalcommunity and leave a comment which includes one of your opal address in the 12th april post which cointains this logo:

6. the Opalcoin wallet:

-Dashboard : an Overview of your wallet, your Opalcoin amounts the Spendable and the Staked ones, the unconfirmed coins. In the right side «Recent Transaction, you can see up to the 6 last transactions :



-Receive : it is where you edit your receiving addresses : the addresses you give to someone who want to send you opal.
At first, you dont have any receiving addresses : to create on, just click « New Address », in the label field, type the name of your payer or the name of the address type if you want to receive opal from different payer (i.e : Saving, opal for staking, Opal games...)



Note that with opal, you can create an Opaque address : which are perfect to receive anonymous payment : the transactions can only be seen by the payer and the receiver. Just check the « opaque address » in the little window which pop after clicking on « New Address »
« Sign Message » and « enter SuperNET » are not ready yet, it will be released soon !

In order to use an address (to give it to your payer for example), you only need to right-click on it and choose « copy address », then you paste it where your payer asked you (email reply, chat, forum...)

Send : is the window you use to pay someone, it is explicit :


Pay to : paste the receiver address
Label : name this address in order to know the owner
Narration : you can add here a short 24 characters text
Amount : enter the amount of opal you want to send


Transactions : is the view where you can check all your transactions,
the staking rewards, noted as Mined, the sent and the received one :




The Other Features are :
 

Address book : which index all the addresses to which you sent opals.

Statistics : which show you the network statistics.

Block explorer : which allow you to look at all the Block and transaction history

IRC : which allow you to chat with Opal members and Opal Team (as helpdesk)

The exchange used is Bittrex.
I will teach you about the settings you need to trade from inside your wallet in a next update of this guide, stay tuned !





EnterSuperNET : Entering the SuperNET ecosystem which federate several cryptocurrency : under integration, be patient.

5.Wallet managment Backup the wallet.dat file & wallets definition


Now you must learn how to make a backup of your wallet.dat file
don't be confused :
wallet.dat is the file which store your amount of coins,

Opalcoin Wallet is the usual name we give to Crypto-Qt client.
for Opal it is Opal-Qt or Opalcoin-Qt:



Step 1 : in your Opalcoin Wallet, click "File" then "Backup Wallet..."

Make 2 backups : one in another folder in your hard drive and do another backup in a usb stick and in case of hard drive failure.

Step 2 : Now you need to know the path where you can manage the wallet.dat file :

on Windows :  C/\Users\Your user name\Appdata\Roaming\Opalcoin



Note: If you can't see your AppData folder : you will need to set your folder preferences in Windows to view normally hidden folders and files :

Open "my computer" and click "Organize" then click "Folder and Search Options",
Then click "Show hidden files, folders and drives" :



on Linux :

By default Opalcoin will put its data here:
~/.opalcoin/
You need to do a "ls -a" to see directories that start with a dot.
If that's not it, you can do a search like this:
find / -name wallet.dat -print 2>/dev/null

on Mac :

By default Opalcoin will put its data here:
~/Library/Application Support/Opalcoin/

the main files inside this Opalcoin folder are :

.lock : BDB lock file (Berkeley DataBase lock file)
blkxxxx.dat : Contains concatenated raw blocks. Stored are actual Opalcoin blocks, in network format, dumped to disk raw.
db.log
debug.log : a useful file in order to fix issues.
opalcoin.conf (optional, in order to add nodes to speed up the connection)
peers.dat : Storage for peer information to make a reconnect easier.
Wallet.dat : which stores your opals.


The most important file is your wallet.dat file, storing your balance information. The other files can be deleted and will be recreated fresh when your wallet will restart.

When you delete all the files except your wallet.dat (to solve some synchronisation issue for example) restart your Opal-Qt wallet and it will begin to re-sync from the start of the chain.
If you deleted your wallet.dat, remember you made a first backup:

-Wait untill the end of the synchronization to see your opals, close your Opal-Qt wallet
-Then copy the wallet.dat you saved in another folder (see step 1)
-Go to the path where the wallet.dat should be (see step 2)
-Paste the wallet.dat

4. Wallet encryption



Once your wallet is synchronized, you need to encrypt your Wallet : this is a very important step.

On your Wallet Dashboard:
Click on "Settings" and choose "Encrypt Wallet"
Choose a password which contains at least 26 characters with not only lowercase : add a few uppercase, numbers and special characters : & ? " $ £ ' - _ ! %

a tip ? : choose something from a book, a sound and transform it a little bit :

example :
Dont step on my blue suede shoes   Change it to :  ?d0ntsteponmyBlueSu6deSh£es

note it very clearly, with black ink on a pocket book and put this pocket book in a safe place.
