Grimm. No one will ever know

Current status

Mainnet online. First block "timestamp":1564997815 Aug. 5th, 2019 @ 9:36am (UTC) mainnet branch

Testnet online testnet branch

  • Financial freedom No founders TAX. All mining rewards go directly to the miners. No ICO, STO, IEO, Premine. No transaction fees.
  • FULLY Anonymous Powered by Mimblewimble. Simple wallet.
  • Grimm wallet with built-in GPU and CPU mining. Easy-peasy, fresh and squeezy

We designed Grimm so that it doesn’t depend on any one person. We don’t control it. Not financially. Not physically. How can decentralized work if only founders or entities controls the system? They accumulate taxes, head the richest lists in their projects, or play an unfair game with an unlimited extra coin emission. Grimm is a classic fork of Beam with other consensus rules, open source, without founders rewards, ico, sto, ieo, premine and other commercial shit. Privacy and scalability - two most prominent problems challenges bedeviling the existing Blockchain ecosystem today. So we chose the Mimblewimble protocol, which has fully addressed these problems initially. We are not in favour of mix decentralized projects with a commercial semblance of decentralization. Grimm's got a different, absolutely decentralized way.

Linux

Ubuntu 18.04

  • Install gcc7 boost ssl packages. sudo add-apt-repository ppa:ubuntu-toolchain-r/test sudo apt update sudo apt install g++-7 libboost-all-dev libssl-dev -y
  • Set it up so the symbolic links gcc, g++ point to the newer version: sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 60
    --slave /usr/bin/g++ g++ /usr/bin/g++-7 sudo update-alternatives --config gcc gcc --version g++ --version
  • Install latest CMake wget "https://cmake.org/files/v3.12/cmake-3.12.0-Linux-x86_64.sh" sudo sh cmake-3.12.0-Linux-x86_64.sh --skip-license --prefix=/usr
  • Add proper QT 5.11 repository depending on your system https://launchpad.net/~beineri (for example, choose Qt 5.10.1 for /opt Trusty if you have Ubuntu 14.04), install sudo apt-get install qt510declarative qt510svg packages and add export PATH=/opt/qt511/bin:$PATH. Go to Grimm project folder and call cmake -DCMAKE_BUILD_TYPE=Release . && make -j4. You'll find binaries in grimm/..., wallet/..., ui/..., explorer/... subfolders.

Mac

Install Brew Package Manager. Installed necessary packages using brew install openssl boost cmake command. Download and install QT5.11 from the official website https://download.qt.io/official_releases/qt/5.11/5.11.0/qt-opensource-mac-x64-5.11.0.dmg.mirrorlist Add export OPENSSL_ROOT_DIR="/usr/local/opt/openssl" and export PATH=/Users//Qt5.11.0/5.11.0/clang_64/bin:$PATH to the Environment Variables. Go to Grimm project folder and call cmake -DCMAKE_BUILD_TYPE=Release . && make -j4. You'll find binaries in grimm/..., wallet/..., ui/..., explorer/... subfolders. If you don't want to build UI don't install QT5 and add -DGRIMM_NO_QT_UI_WALLET=On command line parameter when you are calling cmake.
