dogecoin-fork-panic-sale

There was a momentary panic sale apparently caused by a network fork for DOGEcoin, but it seems things are getting back to normal now. There could be some delays processing transactions though due to some pools and exchanges not running the latest version of the doge client software, and some pools such as Multipool have temporary disabled DOGE withdraws until they fix the problem. Just don’t get the panic get a hold of you, things are already getting back to normal. Below is some info from the developers:

The network has forked around block 104678. From my first investigation, it looks like the version below and above 1.5 disagree on the correct blockchain. Currently, the clients below 1.5 stopped accepting new blocks. Solely the 1.5+ clients are now generating and accepting new blocks. Older nodes will generate blocks too, but those will be rejected by the network as 1.5+ nodes are used by more than 51% of users.

THIS IS NOT A 51% ATTACK!

We are actively looking into why this happened. I can’t say much yet (I’m at work), but the safest currently is updating your client to 1.5.1.

Pool owners: I know about that issue with 1.5+, but there is currently no other way, as we can’t patch 1.4 so fast. We have to investigate why that fork happened. A debug.log of a 1.4 node could help.

Try to reduce your transactions to a minimum while this is being worked on. Check your block count in the bottom right corner of your wallet to see on which side of the chain you are. As of writing this, my client shows ~104773 blocks. This seems to be the currently longest, therefore “correct” chain.

gpu-z-intel-opencl-support

If you are really willing to squeeze every little bit of performance for mining crypto coins with your available hardware you should be aware of the fact that you can also use the most recent Intel integrated graphics cards for mining too. The latest generation of integrated Intel graphics does support OpenCL 1.2 and thus can give you some extra hashrate that is more than yo can get alone out of the CPU only. Note that the OpenCL 1.2 support is found only on 3rd and 4th Generation Intel Core Processors as well as some other more specific models that you probably will not have available in your mining rigs anyway. Older Intel Integrated Graphics may support OpenCL on the CPU only, so they are no good for mining crypto coins unfortunately. Below you can find a list of the supported integrated Intel graphics processors that can be used for OpenCL mining:

4th Generation Intel Core Processors with:
– Intel HD Graphics 4200/4400/4600/5000
– Intel Iris Graphics 5100
– Intel Iris Pro graphics 5200

3rd Generation Intel Core Processors with:
– Intel HD Graphics 4000/2500

Intel Atom Processor Z3000 Series with:
– Intel HD Graphics

Intel Celeron Processor J1000/N2000 Series and Intel Pentium Processor J2000/N3000 Series with:
– Intel HD Graphics

Intel Xeon Processor E3 Family V2/V3 with:
– Intel HD Graphics P4000
– Intel HD Graphics P4600/P4700

You can quickly and easily check if your integrated Intel GPU does come with OpenCL support or not with the help of the free tool GPU-Z if you are not sure what kind of processor or integrated graphics you may have in your systems. Be aware that the supported Intel integrated graphics processors will not be as powerful as a dedicated AMD graphics card, but they still do manage to provide a few times higher hashrate than if you are using the CPU for mining and they can add a bit more performance to your overall hashrate. So why not take advantage if you already have the hardware available…

MtGox has released an official statement today that they will be resuming full operations soon as they have apparently implemented a solution that should enable withdrawals and mitigate any issues caused by transaction malleability. MtGox apparently has developed a workaround that will use a unique identifier created by Blockchain to show whether transactions have been modified or not. This is supposed to prevent any fraudulent use of the malleability issue and protect the assets of MtGox customers.

Resuming Withdrawals
With this new system in place, MtGox should be able to resume withdrawals soon. At the beginning we will do so at a moderated pace and with new daily/monthly limits in place to prevent any problems with the new system and to take into account current market conditions.

In order to launch the new system, we are going through the following steps:
– Re-indexing the entire Blockchain (approx. 32 million entries)
– Fully deploying the new NTX ID
– Implementing a new bitcoin withdrawal queue that needs to be tested
– We will update everyone again by Thursday at the latest.

Additionally, you may have noticed that we have added a new login system that sends you an email when you successfully access your account. This is an additional security layer, but as always we strongly encourage our customers to use the 2-step authorization options available in our Security Center.

Hopefully this will help in stabilizing BTC exchange rate in the next few days, especially after MtGox resumes full trading operations including BTC withdraws and this will calm the situation that has gone crazy. Bitstamp has already restored their automated Bitcoin withdraws, so this announcement from MtGox should also help in restore things back to normal.
