Get Started

To start using Goldcoin, you’ll need a wallet. A wallet is just like your online bank account, only your entire account is stored securely on your local computer or Android device.

From your wallet you can send and receive Goldcoin, manage your address book and review a history of your transactions.

Update: The Windows 0.7.5.0 client below has just been released. It is recommended that all Goldcoin users download and install this software update.

Windows Wallet Client 0.7.5.0

You can also get the Android wallet on: Google Playstore

MAC release notes and support for older OS: Forum Thread

Linux Wallet Client 0.7.2.1

GitHub

Bare Repo: https://github.com/goldcoin/goldcoin/tree/barerepo

Windows Instructions:

Once you have downloaded your client you need to install it by double clicking on and running the executable file you have just downloaded.

Once installed open your wallet by double clicking on the GoldCoin icon on the desktop and let it sync. Once it has completed syncing you’re ready to send and receive GoldCoin.

0.7.1.7
Fixed minor bug in 0.7.1.6 that prevented the difficulty enhancements from actually taking place.

Should normalize difficulty in a few hours.

Ensure you have updated before block 118800

Mandatory update!

0.7.1.6
Fixed difficulty code again, added block queuing without client delay (threaded).

Should normalize difficulty in 1-3 days.

Mandatory forking update!

For those pulling from github you may have to use the following command before your pull will work:

git stash; git fetch origin; git reset –hard origin/master

Thank you for your patience during this time.

0.7.1.5
Potential timewarp issue fixed with mining optimizations.
Note this version of the client is known to lag for ~45 seconds when finding a new block (only applies to people who mine with the daemon/client). Will hopefully address this in the next release.

Optional update.

0.7.1.4
Fixed difficulty code, after 5-10 difficulty adjustments you should be seeing mined blocks once more.
Mandatory forking update!

Note about the frequency of updates:

We are trying to do something that has never been done before and so we regret that there have been so many difficulties but stick with us.. we’re almost there.

0.7.1.3
Fixed a bug in the bitcoin code that made changing chains post a difficulty change very difficult..
Also fixed a false positive issue with regards to the defense on the same matter.
Mandatory update!

0.7.1.2
Fixed an issue that caused network fragmentation/segmentation not to reconcile after a failed 51% attack.
Mandatory update!

0.7.1.1
Fixed an issue when downloading the blockchain from scratch,
Recommended update.

0.7.1
51% defense tweaked. Network segmentation on multi-peer attacks replaced with delay (more efficient).
Time travel attacks fixed. Please be sure to set your system date/time/clocks/timezone right folks, otherwise the client may behave strangely!
Mandatory update! Clients older than 0.7 will cease to sync!
If you are on 0.7, please update to 0.7.1, even though the two are compatible, there are some fail-safes in 0.7.1 that stop you from falsely triggering the defense system that are not present in 0.7

0.7

51% defense system added (first of its kind in the crypto-world!).

Note, if you open this client and after a while find yourself not connected to any nodes, do not worry, this is normal. Simply restart your client. If your number of connected nodes is low,
don’t worry this is also normal(In this case do NOT restart your client).

(this issue should only persist for a few days).

0.6.9.4

This recommended(optional but high priority) update adds extra checkpoints and renames some of the misnamed portions of the client.

Notice for non-windows users: The GLDCoin directory has been renamed to GoldCoin (GLD), you will have to move your wallet file manually.

As always for all users, we recommend taking a backup of your wallet.dat file.

Notice for server operators: Along with the wallet/configuration directory change, there has been a change in the name of the client executables. Please use “goldcoind” for the daemon from now on.

We recommend you first uninstall your previous version of GoldCoin before installing this edition to avoid any conflicts.

Please be sure to report any bugs noticed on the official forum here: Bug Reports

Ps. QRCodes may or may not be affected by the rename.. please generate new QR codes when using 0.6.9.4 or higher… old QR codes are still supported by the old client.
