OpenWeaver is a framework that provides components to easily deploy a high-performance relay network across a global cluster of nodes. Design goals include:

• Speed - Latency optimized relaying
• Efficiency - Low resource consumption
• Blockchain-agnostic - Supports multiple blockchains in the same core network
• Multilingual - Supports projects written in different languages
• Streamlined - Easy to deploy and manage

The repository has submodules, so be sure to clone recursively using

$ git clone --recurse-submodules https://github.com/marlinprotocol/OpenWeaver.git

Alternatively, you can checkout submodules after cloning as well using

$ git submodule update --init --recursive

Prerequisites: cmake >= 3.13, autoconf, automake, libtool, g++/clang++ (must support C++17, newer versions preferable)

The codebase is a standard C++/CMake project.

$ mkdir build && cd build  # to create a build directory

$ cmake .. -DCMAKE_BUILD_TYPE=Release && make -j8  # to build

For builds in a containterized environments with compilation toolchain separate from host machines, see ow_builder.

After building, you can find the following binaries in the build directory:

• ./beacon/beacon - Beacon
• ./relay/eth_relay - Relay
• ./goldfish/goldfish - Toy network for local testing
• ./multicastsdk/msggen - Message flooding tool for testing/benchmarking

• Ethereum - A bridge between Ethereum nodes and the core network is built at ./integrations/eth/onramp_eth

After building,

1. Set up a beacon - ./beacon/beacon
2. Set up a relay - ./relay/eth_relay "127.0.0.1:8002" "127.0.0.1:8003"

You now have a local network running. In a production setting, you would want to run these in different instances as a globally distributed network.

OpenWeaver has a test suite that's integrated with CTest. After building, tests can be run using

$ make test

or

$ ctest
