bitcointalk-dorum-down

One of the largest online communities regarding crypto currencies, namely the BitcoinTalk forum has seen extended downtime for a few days due to an attack and this is certainly not the first time there have been trouble for the forum. The forum operators have reported on twitter and it looks like attackers have compromised the password hashes and email addresses of the registered users. Thus a recommendation was posted that everyone changes their password on BitcoinTalk when it is back online and also change the password in other websites where the user is using the same password (never a wise idea to use the same email and password for multiple websites). There was an attempt to bring back the website today, but it has been taken down again and it will most likely take another day for the forum to be back online, so hopefully tomorrow things should be back online again.

Update: It seems that the BitcoinTalk forum is now back online and working without problems again…

Today is Bitcoin Pizza Day, Here is Why

two-pizzas

Back in 2010 when Bitcoin was still very new and easy to be mined a guy called Laszlo Hanyecz, a programmer from USA and an early Bitcoin adopter, spent 10000 BTC for two pizzas and this is believed to be the first real-world transaction using Bitcons for payment. Laszlo posted his request on the BitcoinTalk forum on May 18th, 2010 and on May 22nd he reported that he has successfully spent 10000 BTC for pizza provided by a user called jercos. So five years ago 10000 BTC could get you two pizzas and now you can get the same with just a small fraction of 1 Bitcoin and 10000 BTC at the moment equal about 2,380,000 USD. This is the actual origin of the Bitcoin Pizza Day, so happy celebrations today exactly 5 years layer…

New sgminer With Optimized Quark and Qubit Binary Kernels

sgminer-5-1-1-quark-qubit

The Quark and Qubit crypto algorithms continue to be quite profitable, but until recently these algorithms were mostly in the Nvidia domain as the ccMiner for Nvidia GPUs was faster than the available performance on AMD hardware. There is however a new sgminer fork with compiled Quark and Qubit kernels that was sent to us that brings up the hashrate significantly on Pitcairn and Tahiti AMD GPUs. We have tested this particular sgminer on a Radeon R9 280X and we are getting about 11.22 MHS on Quark with a non overclocked GPU and about 12.3 MHS on Qubit and you can get higher with OC and increase in the Intensity. Quark is apparently quite profitable at the moment on NiceHash and WestHash due to the interest in SharkCoin or so it seems, so if you have some idle AMD GPUs that you are wondering where to point them there. Do note that the sgminer is not compiled by us and it comes with the standard OpenCL kernel files, so you need to use the binaries for the higher performance. Since we have not compiled this sgminer from source and it was sent to us already compiled we would recommend to be cautions and not run it on systems with wallets installed, just in case!

– To download and try the sgminer 5.1.1 with optimized Quark and Qubit kernels for Windows OS…
