GPU mining typically requires a 64-bit edition of Windows and the GPU mining software requires Redistributable Packages for Visual Studio 2013 and Redistributable Packages for Visual Studio 2015 to be installed on all computers where the GPU mining will be running. Awesome Miner – Mining made 64 bit bitcoin miner with powerful management! Eliminates Bitcoin blockchain problem C-Bit is a parallel Bitcoin to the original blockchain.
Based on Bitcoin source for stability C-bit uses the modern Bitcoin source code as a starting point, and when Bitcoin gets updated in the future, C-Bit will automatically get updated as well, ensuring that C-Bit is always up-to-date with every Bitcoin patch, fix and update for maximum compatibility. Compatible with all Bitcoin-based technologies Because C-Bit is so tightly paired to the original Bitcoin source, it is compatible with any product or service that works with Bitcoin blockchain technology. Check the source The code, because is based on the original Bitcoin code, is open source. Because of this, C-Bit is every bit as easy to work with as Bitcoin is – so there is a world of opportunity waiting for developers and an entire community there to back them up. I have added ports for low difficulty and high difficulty on minerpools.
Low difficulty should only be used for less than 100GH. Normal difficulty should be used for most mining. Will not work reliably for Nicehash! High difficulty should be used for greater than 50TH. All ports are configured for varr-diff to optimize miner operation once mining has started. The pool is still running without any fees, so it is as good as solo mining! C-Bit This is a community project.
Could an IBM mainframe from the 1960s mine Bitcoin? The idea seemed crazy, so I decided to find out. I implemented the Bitcoin hash algorithm in assembly code for the IBM 1401 and tested it on a working vintage mainframe. It turns out that this computer could mine, but so slowly it would take more than the lifetime of the universe to successfully mine a block. How Bitcoin mining works Bitcoin, a digital currency that can be transmitted across the Internet, has attracted a lot of attention lately. If you’re not familiar with how it works, the Bitcoin system can be thought of as a ledger that keeps track of who owns which bitcoins, and allows them to be transferred from one person to another.
The interesting thing about Bitcoin is there’s no central machine or authority keeping track of things. Mining requires a task that is very difficult to perform, but easy to verify. Bitcoin mining uses cryptography, with a hash function called double SHA-256. With a cryptographic hash, there’s no way to get a hash value you want without trying a whole lot of inputs. But once you find an input that gives the value you want, it’s easy for anyone to verify the hash.
The dark blue boxes mix up the values in non-linear ways that are hard to analyze cryptographically. If you could figure out a mathematical shortcut to generate successful hashes, you could take over Bitcoin mining. The Ch “choose” box chooses bits from F or G, based on the value of input E. Internally, the computer was very different from modern computers.
Since it was a business machine, the computer used decimal arithmetic instead of binary arithmetic and each character of storage held a digit, 0 through 9. Performance comparison The IBM 1401 can compute a double SHA-256 hash in 80 seconds. It requires about 3000 Watts of power, roughly the same as an oven or clothes dryer. 125,600, which is about a million dollars in 2015 dollars. Networking You might think that Bitcoin would be impossible with 1960s technology due to the lack of networking.
