Hello everyone,

DGW3
A few days ago I posted that we were thinking about changing our difficulty re-adjustment algorithm from KGW to DGW3. The main reason for this upgrade is the swing in blocktimes caused by jumping miners. I promised to give an update today.

Meanwhile, there has been some discussion about other methods that could also be beneficial to Guldencoin. BTMs long coin maturity is an interesting idea that might make it into the coin when more discussion has taken place. For now we believe the change from KGW to DGW3 is the first thing we need to do and we hope it will be enough to stabilize the network blocktime.

Two other things have popped up that need to be taken care of.

Protocol version revert
When KGW was added to Guldencoin, the protocol version was used to reject old software from the network. This means that the protocol version is not in sync anymore with Litecoin and Bitcoin protocols. We would like to have it in sync again as this will make development easier and documentation for the given versions in the other coins will still apply to Guldencoin that way.

Version 1.3
Main changes are DGW3 and the protocol version revert and because of these changes, we need to perform a hard fork in the network. The new software version number will be 1.3 and it wont be able to connect with pre-1.3 software. Updating your wallet is mandatory!

The plan
Times are CEST timezone (UTC+0200)
Thursday 25th of September we will cause a hard fork.
18:30 we will start by shutting down the seeds one by one.
19:00 the last seed will be shut down, the last block known by this seed will be the last KGW block.
19:01 We will hard code the next block number into the new software and start compilation of the guldencoind (software ran on the seeds).
19:05 We will start compiling the guldencoin-qt wallet for Windows and Mac OSx.
19:15 First seed is started with the new 1.3 software, other seeds follow one by one.
19:16 We test the guldencoin-qt wallet with the new network
19:17 New software source code is pushed to Github.
19:20 The new guldencoin-qt wallet is published on the website and available for download.

We will keep everyone updated about the process through a topic in the forums.

Exchanges, payment providers, etc.
We advise operators for automated systems to suspend processing the chain 2014-09-25 18:00:00 until the new wallet (v1.3) has been installed. We will approach as many operators as we can to inform them of these plans.

Topic about this on the Guldencoin forum: https://forum.guldencoin.com/index.php?topic=548.msg4668

Now we know what to expect. Good detailed info and it seems carefully planned.

German, english, dutch and french altcoinsection updated with the info:

I think DGW3 is a good way to go and a bold move. The way this update is handled will make or break the coin and show confidence to the rest of the world that NLG has got a great team behind it!
