This implements the compact block filter construction in BIP 158. The code is not used anywhere in the Bitcoin Core code base yet. The next step towards BIP 157 support would be to create an indexing module similar to TxIndex that constructs the basic and extended filters for each validated block.

python3 -m venv venv
. venv/bin/activate
pip3 install .

python3 tests/simple_test.py

Install brew:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

brew install python3  
brew install boost  

At this point the only error is can’t find boost_thread lib

The issue is the homebrew boost ships libboost_thread-mt libs but doesn’t include plain libboost_thread, so clang can’t find it. Interestingly, homebrew boost does have both plain and -mt files for the libboost_system libraries.

$ find /usr/local/lib/ | grep boost_thread  
libboost_thread-mt.a  
libboost_thread-mt.dylib  

Solution, with no guarantees that this is "the Right Way to do things", but appears to work fine for the configure stage:

cd /usr/local/lib  
ln -s libboost_thread-mt.a libboost_thread.a  
ln -s libboost_thread-mt.dylib libboost_thread.dylib  

The primary build process for this repository is to use GitHub Actions to build binary wheels for MacOS, Linux (x64 and aarch64), and Windows and publish them with a source wheel on PyPi. See .github/workflows/build.yml. CMake uses FetchContent to download pybind11. Building is then managed by cibuildwheel. Further installation is then available via pip install chiabip158 e.g.

Contributions are welcome and more details are available in chia-blockchain's CONTRIBUTING.md.

The master branch is usually the currently released latest version on PyPI. Note that at times chiabip158 will be ahead of the release version that chia-blockchain requires in it's master/release version in preparation for a new chia-blockchain release. Please branch or fork master and then create a pull request to the master branch. Linear merging is enforced on master and merging requires a completed review. PRs will kick off a GitHub actions ci build and analysis of chiabip158 at lgtm.com. Please make sure your build is passing and that it does not increase alerts at lgtm.
