cpuminer-koto is a fork of cpuminer-opt by Jay D Dee, which itself is a
fork of cpuminer-multi by TPruvot with a list of optimizations added on top of
it. The optimizations have been imported from other miners developped by lucas
Jones, djm34, Wolf0, pooler, Jeff garzik, ig0tik3d, elmad, palmd, and Optiminer,
while Jay D Dee performed even further optimizations.
Jerônimo Cryptão performed benchmarks and extracted relevant functionality,
that is required for Koto mining, while pruning the remaining bits of the client
in order for the resulting miner to be as light as possible.
- An x86_64 architecture CPU with a minimum of SSE2 support. This includes Intel Core2 and newer and AMD equivalents. In order to take advantage of AES_NI optimizations a CPU with AES_NI is required. This includes Intel Westbridge and newer and AMD equivalents. Further optimizations are available on some algoritms for CPUs with AVX and AVX2, Sandybridge and Haswell respectively.
Older CPUs are supported by cpuminer-multi by TPruvot but at reduced performance.
ARM CPUs are not supported.
If your system is not supported by cpuminer-koto, the recommended miner for
the Koto cryptocurrency is cpuminer-yescrypt
by koto-dev.
- A 64-bit Linux OS. Ubuntu- and Fedora-based distributions, including Mint and CentOS are known to work and have all dependencies in their repositories. Others may work but may require more effort. 64 bit Windows OS is supported with mingw_w64 and msys or pre-built binaries.
MacOS, OSx is not supported.
- A Stratum pool.
For Ubuntu-based systems, the following list of dependencies need to be satisifed:
sudo apt-get install \
build-essential \
libssl-dev \
libcurl4-openssl-dev \
libjansson-dev \
libgmp-dev \
autoconf \
automake
For other Linux-based systems, such as Fedora, Arch etc., the equivalent packages need to be obtained and installed, accordingly.
Then, one needs to simply run ./build.sh from the root directory of the cpuminer-koto repository.

AMD CPUs older than Piledriver, including Athlon x2 and Phenom II x4, are not
supported by cpuminer-koto due to an incompatible implementation of SSE2 on
these CPUs.
Users are encouraged to post their bug reports in the Issues section.
All problem reports must be accompanied by a proper definition. This should include how the problem occurred, the command line and output from the miner showing the startup and any errors.

After all, those morning cups of coffee need to come from somewhere, in order to enable writing efficient code :)
Thanks and happy mining!
