About

This is currently a work in progress. There is nothing to see here 🤷

Features

• pseudonymous economy (sellers are only identified by their usernames and trusted based on their reputation)
• no registration required (for buyers only)
• no KYC or AML
• no listing fees
• no sales tax (transaction fees will be paid to miners in place of sales tax. I mean, this is crypto LOL)
• no other fees (except for miner transaction fees and shipping costs)
• buy and sell products with monero (and possibly other private-by-default crypto in the near future)
• seller reputation system
• product rating system
• centralized database (for now, since I don't know how to implement a decentralized database or p2p network)
• and much more ...

Compiling neroshop from source

1. Install dependencies

Debian/Ubuntu

sudo -s -- << EOF
# prerequisites
sudo apt install build-essential cmake git
# neroshop, dokun-ui
sudo apt install libx11-dev libgl1-mesa-dev libglu1-mesa-dev libssl-dev libpq-dev postgresql
# monero-cpp (monero)
sudo apt update && sudo apt install pkg-config libssl-dev libzmq3-dev libunbound-dev libsodium-dev libunwind8-dev liblzma-dev libreadline6-dev libldns-dev libexpat1-dev libpgm-dev qttools5-dev-tools libhidapi-dev libusb-1.0-0-dev libprotobuf-dev protobuf-compiler libudev-dev libboost-chrono-dev libboost-date-time-dev libboost-filesystem-dev libboost-locale-dev libboost-program-options-dev libboost-regex-dev libboost-serialization-dev libboost-system-dev libboost-thread-dev python3 ccache doxygen graphviz
EOF

Arch

# prerequisites
sudo pacman -Sy --needed base-devel cmake git
# neroshop, dokun-ui
sudo pacman -Sy --needed libx11 lib32-mesa lib32-glu openssl postgresql
# monero-cpp (monero)
sudo pacman -Syu --needed boost openssl zeromq libpgm unbound libsodium libunwind xz readline ldns expat gtest python3 ccache doxygen graphviz qt5-tools hidapi libusb protobuf systemd

2. Clone submodules and nested submodules

cd external
git clone --recurse-submodules https://github.com/monero-ecosystem/monero-cpp.git
git clone --recurse-submodules https://github.com/rg3/libbcrypt.git
git clone --recurse-submodules https://github.com/nayuki/QR-Code-generator.git
git clone --recurse-submodules https://github.com/nlohmann/json.git
git clone --recurse-submodules https://github.com/curl/curl.git
cd ../

3. Modify external/monero-cpp/external/monero-project/CMakeLists.txt: option(BUILD_GUI_DEPS "Build GUI dependencies." ON)

4. Build monero-project twice to create libwallet_merged.a and other .a libraries

cd external/monero-cpp/external/monero-project && make release-static && make release-static
cd ../../../../

5. Build libcurl (skip this step if libcurl is already installed on your system)

cd external/curl
# build with ./configure (libcurl.a will be installed in both: neroshop/external/curl/lib/.libs/ and /usr/local/lib/)
autoreconf -fi
./configure --with-openssl --disable-shared
make
sudo make install
cd ../../

6. Build neroshop (along with dokun-ui)

# Build dokun-ui
# make sure CMakeCache.txt, cmake_install.cmake, and Makefile have all been deleted if not
cd external/dokun-ui
cmake -G"Unix Makefiles"
make
cd ../../
# Build neroshop
cmake -G"Unix Makefiles" -DNEROSHOP_USE_POSTGRESQL=1 -DPostgreSQL_TYPE_INCLUDE_DIR=/usr/include/postgresql/
make

Setting up PostgreSQL

# Open the configuration file (change the "14" to your current postgresql version)
sudo gedit /etc/postgresql/14/main/pg_hba.conf

# Edit "pg_hba.conf" (change authentication methods from "peer" to "trust"):
"local   all             postgres                                trust"

# Restart the server for the changes in "pg_hba.conf" to take effect: 
sudo service postgresql restart

# Login to the psql shell as user postgres:
psql user=postgres
    
# Change the password of postgres (within the psql shell)
ALTER USER postgres PASSWORD 'postgres';

# Create a test database
CREATE DATABASE neroshoptest;
    
# Leave the psql shell
\q

# You may restore the "pg_hba.conf" values back to the defaults if you wish

Contributions

I can't do everything on my own with my current knowledge and programming skills, so I will need help with some things. Though I am poor as shit (recently got out of NEETdom so yeah ...), I will open a paid bounty program to encourage individuals who have at least some experience in c++ programming to contribute to my project and help bring this project to life.

This is a one-time pay for each task. Payments will be in XMR.

We can negotiate payment if you feel the bounty price is too low.
