Mammon

Will slowly be an ETH consensus client for research purposes.

Written in C++, currently only has basic types for phase0, their serialization and Merkleization. This is very skeletal and is only here to test a CI environment, things will move drastically from commit to commit. The only functionality currently is in test_ssz which tests the serialization, deserialization and Merkleization, as well as the yaml deconding/encoding of the basic types. Relies on Acutest for basic testing and on yaml-cpp for yaml decoding/encoding.

Build

Warning: At times (for example now) this code will only build on specific CPUs. Currently it should only build on CPUs supporting SHA-ni extensions. I will update with runtime checks after different extensions assembly has been implemented.

$ mkdir build
$ cd build
$ cmake .. -DMINIMAL=true
$ make

Place the eth2 test vectors from the eth2 spec tests repo in the root directory of mammon (this repo has one one test-vector for each type). Run the tests with

$ make test

Setup

format is Google C++ Style Guide with the only modifications that indentation is 4 characters and column width is 120. Enforced with clang-format. Code is checked with clang-tidy and cppcheck.

I'm testing on Arch linux and compiling both with gcc and clang, using C++20. This repo is under GPLv3 with the caveat that acutest is released under MIT license.

• No Doxygen strings.
• No error checking.
• Not portable.
