On Nov 11th, the Goldcoin developers will be releasing an updated version of the Goldcoin Core client software. This upgrade will replace the previously scheduled RBH.


It was determined this week that we did not have a required consensus of nodes to fully adopt the RBH. This would have resulted in a critical network split creating two versions of the Goldcoin blockchain. As you can see using the network tool below our decentralized network is highly distributed.

Rather than risking the negative effects of a network split, the development team has decided to move forward with a traditional hard fork using an updated client that will remain backward compatible for an extended period.

This revised update will allow us to increase our network capacity as previously scheduled without disrupting our network or creating an inflationary event.

[Key benefits]
  • No risk of network split
  • The update will be backward compatible
  • Network nodes will have 6 months to upgrade
  • There will be zero inflation
  • Nodes won't be burdened with the storage requirements of the BTC blockchain
  • Tx throughput will increase to ‭1,120‬ TPS
  • Our immutable ledger will remain fully intact

This revised update, to be released on Nov 11th, will allow us to increase our network capacity (as previously announced) without disrupting our network or creating an inflationary event for users.

Mining & Pools / Current Status of Goldcoinpool.com
« on: October 19, 2019, 06:22:06 pm »
The Goldcoin Team owns the domain name GOLDCOINPOOL.COM.

In the past, this domain has been used to redirect traffic to a mining pool operated by Gold Buffalo. However, it was decided by the pool operator that the pool would be decommissioned for the time being. His stated plans are to build another mining pool after the RBH.

So the team has decided for now to redirect website visitors to the Mining Pool Board of this forum.

Once GB has his new pool up and running, we will consider redirecting traffic to the new pool. Or in the event that does not occur we are open to redirecting traffic to another mining pool.

Meta / FIXED: Problem with Registration Questions
« on: October 18, 2019, 10:13:02 am »
Today, it was discovered that one of the registration questions had a misspelled answer.

'Mecury' is not the closest plant to the Sun.

The error prevented anyone from registering an account on the forum.

This issue has now been resolved!  :thumbsup:

iOS App Support / Known issues affecting the legacy iOS App
« on: October 18, 2019, 08:09:03 am »
There are currently two known issues with the legacy iOS app.

1. Upgrading to iOS version 13.1.2 breaks the app and prevents sending of coins.

2. The Bittrex delisting broke the displayed exchange rate function.

Our developers are aware of the issues listed above and are working to patch the app.

We currently do not have an ETA but will be updating this post regularly as the work progresses.

Service Discussion / Cryptopia Exchange Maintenance Issues
« on: November 01, 2018, 12:56:23 pm »

As you are all aware, the Cryptopia exchange wallet was placed into maintenance on September 5th, 2018 in response to an orchestrated attack.

In response, the Goldcoin developers immediately began working to strengthen our client by adding ACPD (Advanced Check Pointing w/ Difficulty detection) and patching the recently discovered Bitcoin bug known as CVE-2018-17144. The Goldcoin network is now stronger than it's been at any time during its long 6-year history.

Please make sure you are running the latest version of the client wallet which is version 0.14.4. It can be downloaded here.

Exchange Shortage:

According to Cryptopia, this attack allowed a user (or users) to double-spend GLD on the exchange, leaving a shortage of 1,360,108 GLD relative to user balances. While the Goldcoin developers and Cryptopia have put into place safeguards to prevent this from ever happening again, we've been asked to help Cryptopia reconcile this balance deficient before trading is resumed.

The Goldcoin developers have offered to pay 300K GLD to Cryptopia to help them with this process. I personally feel that because the Goldcoin wallet was partially responsible for the success of the attack, that's the least we can do. We have extended this offer to Cryptopia today and asked them to trade the other available exchanges to make up the remaining shortage.

In my opinion, this is a good offer considering Goldcoin is open-source, decentralized, and supported by volunteers. We all have a duty (exchanges included) to contribute to the safety and well-being of the network. Monitoring internal and external networks, along with transaction and trading activities, can go a long way in countering these types of attacks.

Community donations:

If you would like to help Cryptopia in making up this balance deficit, you can send GLD to the following address:

GLD: E3uSaQHDx1ngQsNvLoHx64bqywyQaxuY8n


In conclusion, we have sent our offer to pay 300K to Cryptopia today. I will update this thread once we receive their response.

Please feel free to post your comments below.

Yesterday, we released a mandatory update for the Goldcoin Client.

Unfortunately, we have been unable to reach Hash-to-Coins and they have not updated their wallet as requested. Do not mine GLD on this pool. If you mine this pool, you risk wasting your hashpower since their chain might become forked from the network.

We recommend that you switch immediately to: https://gld.thecoin.pw/

Also, if you haven't done so yet, please update: https://www.goldcoin.org/downloads.html

In order to remain compatible with the network you must update your client. You should close your Goldcoin client, if it's running, before attempting to install this patch.

The development team is currently on standby in the forum in the event you require technical assistance during this time.

CALGARY, AB, April 16, 2018 -- GOLDCOIN (GLD) has kicked its mission of creating the world's greatest form of money into high gear by tapping the talents of Adam Sharek, the team's new Head of Exchange Relations.

As Head of Exchange Relations, Adam is proactively forging rewarding relationships with cryptocurrency exchanges to increase GoldCoin's public profile, legitimacy and availability. He's enthusiastic about making a difference in global economies by ensuring more people get access to crypto, but his constructive attitude isn't the only asset that he brings to the table. He also has direct experience working with multinational companies, such as Quaker and Coca-Cola. As the founder of a successful real estate company, he's also no stranger to building mutually beneficial professional bonds.

According to industry insiders, Adam comes to the GoldCoin team at the optimal time to help the growing cryptocurrency attain new levels of success. Although the currency's developers have clearly devoted immeasurable time and hard work to creating a crypto wallet client fit to resist the ups and downs of volatile markets, exchanges represent another critical avenue of outreach. Adam's formidable ability to forge strong business ties will prove essential as GoldCoin moves into the future and achieves true ubiquity.

Cryptocurrency exchanges are growing in number, and as they do, it's becoming increasingly imperative to reach out to new investors. Adam and the GoldCoin devs firmly believe that engaging these platforms will mean revolutionary things for ordinary people's ability to get involved in crypto freely. The team looks forward to redefining wealth building together as GoldCoin's strength as an investment vehicle inevitably swells.

Project Development / API script conversion from GET to POST Method
« on: February 13, 2018, 10:18:23 pm »
I'm working on a script that will slowly accumulate GLD over time. However the following script is using GET and I need to use POST method:

API Docs:

Screenshot 2 >> https://i.stack.imgur.com/C3EJr.png


Code: [Select]


// Generate random amount between 28.00 and 30.00
$ran1 mt_rand(28003000);
$ran2 $ran1/100;

// Config
$sAPIKey ""// private key
$sAPISecret ""// api secret

$sPair "GLD_BTC";
$sRate "0.0001";
$sNonce time();

// Request
$sRequest "https://someexchange/api/private/submitorder?API_KEY=" $sAPIKey "&Market=" $sPair "&Type=" 'Buy' "&Amount=" $ran2 "&Price=" $sRate "&nonce=" $sNonce;



$ch curl_init($sRequest);

// disable cert validation
curl_setopt($chCURLOPT_SSL_VERIFYHOSTfalse);  // shouldn't need this

curl_setopt($chCURLOPT_HTTPHEADER, array('apisign:' $sSign));
$execResult curl_exec($ch);


Conversion to POST anyone?  :think:
