Windows wallet in OP 404's.

The first step before touching any file in your Opalcoin folder is to backup your wallet.dat file.
Under the file header, select backup wallet. It's smart to backup to another disk in case of hard drive failure.


After backing up your wallet, close it and go to your C:\ drive then navigate to the following:
C:/ > Users > Your Username > App Data > Roaming > Opalcoin

In the Opalcoin folder you will see the above files which are created after first starting your wallet. The most important file is your wallet.dat file, storing your balance information. The other files highlighted in red can be deleted and will be recreated fresh when your wallet is started. If you also delete your wallet.dat file replace it with your backup you will have created.

Note: If you can't see your App Data folder (If you can skip this) you will need to set your folder preferences in Windows to view normally hidden folders and files.
Open to 'my computer' and click Organize and Folder and Search Options


Then click Show hidden files, folders and drives.


Finally, once contents are deleted except your wallet.dat, restart your Opalcoin wallet and it will begin to re-sync from the start of the chain. Your balance will appear as zero and will rise as the blockchain downloads and confirms your transactions.

Hope this helps out!

Nice Voidlord!

Good job stepping up to monitor the thread and answer questions/create tutorials/faqs! The more helpers the merrier

I was actually thinking of also creating a text w/picture tutorial for how to re-sync the blockchain from scratch. (how to find app data folder (on windows for now), how to back up wallet.dat, delete everything else etc.) Because it seems to come up in the IRC sometimes, and it can be challenging to explain the steps through text many times to new users And of course, we should realize, the greater number of people OPAL/Crypto in general attracts, the more these questions will be asked!

Maybe one day the OP can be updated with "OPAL's helpful tips and faqs" (including links to all these tutorials/faqs and Truthers trading tips)!

Cheers

Edit: I think I stumbled across something 

No worries, you are welcome.

Thank you mates ! (PM sent, noashh)

Thanks for your questions Toldy, I added these into the Colored Opal FAQ

For those who do not know.... opalcoinradio.com is live

https://docs.google.com/document/d/1AnkP_cVZTCMLIzw4DvsW6M8Q2JC0lIzrTLuoWu2z1BE/edit#

Completely decentralized

What I'd really like to see is a whitepaper that explains how a standard opal transaction can be colored/uncolored.

Where is the coloring information stored and how is it verified?

Does any of it go through a centralized "coloring transaction server" or are there special nodes that do the verification and storage?

How does this technically work?

Thanks a lot for your time. At the moment really busy, going to try soon.

gratz for lvl up 

welcome Voidlord, glad to have you on board !

What is colored coin and colored opal ?
By coloring an opal you turn it into a token that represents anything you want to trade: Shares, Gold, Houses, Artwork, Commodities....
Colored Coins enable us to create Smart Property on top of the Opal blockchain.

Smart properties are transferable like tickets and certificates, and in addition, every particular smart property is both unique and atomic. Only one smart property of a given identifier can be created, and once created it may not be subdivided.
Smart properties can be used to indicate ownership of an unique real-world asset.

Do i need a specific wallet to use Colored opal ?
Yes, you need an color-aware wallet: the colorcore web wallet

What features is included in the Colorcore?
the Colorcore includes:
-Client Side Encryption: Nobody can't touch your funds.
-Easy Crowdfunding Tools
-A colored coins block explorer
-2 Factor Authentification
-and more...

What is the benefit of colored opal ?
Instead of just sending cash through the Opal network, you can use it to trade anything you want.
With colored opal we can explore new possibilities like advanced financial tools, smart contracts and peer-to-peer exchange over the Internet.
Colored coins adds a new layer to Opal that make it much more useful.

How can i get colored opal ?
There’s no need to purchase extra coins, just use regular Opal and the colorcore wallet to create and transfer assets.

Do i need development skills to create such property, such asset ? on top of the Opal Blockchain ?
No, you dont need any technical skills to create colored coins.

Do you need to change the protocol ?
No, you must see colored opal technology as an implementation in the form of a floating set of specifications that can be implemented in third-party Qt clients, rather than in the protocol itself.

Did colored opal work with opaque technology ?
Not currently...

Is colored opal value as the same value as classic opal ?
Yes, an opal is an opal, but you should see a colored coins as a tool: a token, a title, a key...
color a coin is like writing something unique on it.
A good example is: color a coin which represents the car and who owns that coin owns the car.
A futuristic example will be: Only people who sign an address holding a colored coin can use that car.
The buyer gives you 10,000 Opals, and you give him the colored coins, the key which allow the buyer (and nobody else) to open it, start it... use it.

Can i modify a colored opal into a classic opal ?
Yes.

Does colored coin need a centralized "coloring transaction server", are there nodes that do the verification and storage?
No, it is completly decentralized.

How does this technically work?
for such technical approach, please read: https://docs.google.com/document/d/1AnkP_cVZTCMLIzw4DvsW6M8Q2JC0lIzrTLuoWu2z1BE/edit#

What is the limit of colored opal ?
Your, Our imaginations. You are free to link anything which can be trade...  without central authority, notarial act, or middlemen...
to give you ideas, let's list examples:

-Shares A company could issue colored coins representing shares. The shares could then be traded frictionlessly through the Opal infrastructure.
-Backed coin A bank could issue colored coins backed by a cash reserve[/b]. People could withdraw and deposit money in colored coins, and trade those, or use them to pay for goods and services. The Blockchain becomes a system allowing to transact not only in Opal, but in any currency.

-Locks on cars or houses could be associated with a particular type of colored coins. The door would only open when presented with a wallet containing that specific coin.

-Tickets are transferable bearer tokens which are designed to be eventually redeemed for some kind of real world value.
Examples of tickets include:
Event entry passes
Store coupons and special offers
Frequent flyer miles and other redeemable rewards

-Certificates are transferable and redeemable in the same manner as tickets, and they additionally entitle the bearer to some kind of revenue paid through the blockchain.
Certificates can be used for bearer securities, such as securitized loans, mortgages, bonds, and dividend-paying stocks.

....the potential is huge, we do not believe we have fully mapped out all the possibilities it opens up !

Take it easy friend ! For IRC I think you'll need to log in first now. After,better look more about opal coin I think,skip this one only because you can't load wallet is a bit fast .... This let me remember when I sell 10k XC at 3k only because wallet was buggy and some week later the price jump to 15k,after 30...70... 150... 300... Ehh. WHen you'll found a dev team know what they do ,working hard... better invest early

Development are constant,price stable,people are very confident and some nice feature coming soon too.Everything you'll need from here is patience. Opal was a safe bet from the beggining, should take a deeply look

Hello Ontopicplease,

You can try this first:
Close the Opal Qt GUI.
you have windows 8 : Open a File Explorer window and click the "View" tab and tick "File name extensions".
then go here:
C:\Users\YourUserName\Appdata\Roaming\Opalcoin
Copy the file wallet.dat and paste it in another folder you can found with ease. check if you really did this copy/paste in the new folder.
in C:\Users\YourUserName\Appdata\Roaming\Opalcoin delete blk0001.dat and rename the wallet.dat wich is in the Opalcoin folder: wallet_test.dat
Start the Opal Qt, wait the total blockchain synchronisation without worrying about your coin (remember they are safe in two locations: the wallet.dat you saved in another folder and the wallet_test.dat you left in C:\Users\YourUserName\Appdata\Roaming\Opalcoin
if everything is ok, close your Opal Qt, go to find your wallet.dat in the other folder and copy/paste it in
C:\Users\YourUserName\Appdata\Roaming\Opalcoin
then open your Opal Qt !

if after that you still encounter Wallet crashes please go here:
http://webchat.freenode.net/#
choose a nickname
type #opalcoin in "channel"
put the captcha
 and wait 20 second, you will be connected on IRC, then left click on Bassguitarman and choose query, he will be glad to help you to fix your Issue



Hope it helps,

P.S: please dont be so fast to test, ask, judge and quit Opal, here you really have help, just read back a little bit the thread to see the techs are quickly fixing issues
