Fuzzamoto\n\nFuzzamoto provides a framework and fuzzing engine for coverage-guided fuzzing\nof Bitcoin full node implementations.\n\n* **Implementation Agnostic**: The same tests can target different protocol\n  implementations and compare their behavior (e.g. [Bitcoin\n  Core](https://github.com/bitcoin/bitcoin),\n  [btcd](https://github.com/btcsuite/btcd),\n  [libbitcoin](https://github.com/libbitcoin/libbitcoin), ...)\n* **Holistic**: Tests are performed on the full system, not just isolated\n  components, enabling the discovery of bugs that arise from the composition of\n  different components\n* **Coverage-Guided**: Fuzzing is guided by coverage feedback\n\n*It is not meant to be a replacement for traditional fuzzing of isolated\ncomponents, but rather a complement to it.*\n\nCheck out the [book](https://dergoegge.github.io/fuzzamoto/index.html) for more information.\n\n## Trophies\n\n| Project
