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

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 1 >> https://i.stack.imgur.com/8OjTk.png
Screenshot 2 >> https://i.stack.imgur.com/C3EJr.png

Script:

Code: [Select]
<?php

ini_set
('display_errors''On');
error_reporting(E_ALL);

// 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;

echo 
$sRequest;

$sSign=hash_hmac('sha512'$sRequest$sAPISecret);

$ch curl_init($sRequest);

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

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

?>

Conversion to POST anyone?  :think:

Technical Discussion / MOVED: My Wallet Wont Sync

I was reading an excellent article today on disabled opcodes and was reminded of the detrimental and damaging nature of RBF.

"We know that Satoshi believed 0-conf transactions on the Bitcoin network could be secure enough to verify a transaction within 10 seconds or less, but only in a network topology where miners sustain many simultaneous "edges" or active connections. This would ensure fast propagation through the network, putting double spend attempts with even a slight delay from the original at a severe disadvantage, and highly unlikely to be confirmed before the original. Despite this, many have over-emphasized the risk of 0-conf transactions and exacerbated the problem by introducing replace-by-fee transactions which make the possibility of double spending much higher. This effectively breaks the security of fast 0-confirmation transactions. Lucky for us, BCH does not have this impedance and we are sure to see innovation in this area."

I've been getting a lot of requests lately from new users wanting to buy Goldcoin. Since Bittrex and Cryptopia have closed new registrations, I think this forum might work as a temporary solution.

I would caution anyone that makes a deal in the forum to use a trusted member for escrow, especially for larger amounts.
