BlakeBitcoin (BBTC) Blake-256 based cryptocoin

21 May

blakebitcoin-crypto

BlakeBitcoin (BBTC) is a clone of Bitcoin with the same reward structure starting with 50 coins per block and a total of 21 million coins, but instead of SHA-256 the coin uses Blake-256 algorithm. The block target time is 1/4 of Bitcoin’s to account for extra hashing speed of Blake-256. The difficulty retarget is at 8064 blocks and the reward halving every 210,000 blocks. The difficulty adjustment is also same as per Bitcoin. BLAKE hash is one of the five hash functions in the final of the NIST SHA-3 Competition. BLAKE is one of the simplest designs to implement, and relies on previously analyzed components: the HAIFA structure and the ChaCha core function. What is the most interesting thing about BlakeBitcoin is that it is merge mined with multiple other Blake-256 crypto coins.

New X11/Darkcoin AMD GPU Miner With 40%-50% Performance Increase

21 May
2014

x11-sgminer-performance-increase

It seems that the OpenCL kernel for Darkcoin for sgminer has been optimized by a user called girino over at the Bitcointalk forum to bring some nice performance improvement in the hashrate when mining X11 crypto coins such as Darkcoin. Do note that you need to use a precompiled miner with no source code and there is a 2% developer fee on the mining (the miner is hardcoded to mine at another pool for the developer), but with 40-50% performance increase over the latest sgminer with support for DRK the 2% dev fee is acceptable. We have tested the new x11-sgminer on a Radeon R9 280x and and we are getting a boost from about 2-2.1 MHS to a little over 3.1 MHS with the new miner. The author has provided only compiled versions of the miner for both Windows as well as for Linux, but has breached the sgminer GPL license by not publishing the source of the miner! So we recommend to download the already available fork by lasybear with the same kernel that provides the same higher performance, but also has the source of the sgminer available and no forced fee.

– Get the new open source sph-sgminer_x11mode with performance increase for X11 crypto mining instead…

QuazarCoin (QCN) is the new generation of cryptocurrency which is based on the CryptoNote protocol and uses the CryptoNight algorithm. The CryptoNight algorithm is the most democratic today, fully ASIC-resistant and only CPU-mineable. QuazarCoin was launched May 8, 2014 after discussion in the community, without premine or instamine. QuazarCoin protects your data and privacy through unlinkable transactions with ring signatures. The main concern of QuazarCoin is usability optimization.
