alberta-buck-kernel

The compiled Alberta Buck kernels for Python: integer monetary arithmetic bit-identical to the Solidity contracts, and the BN254 identity, wallet and registry cryptography.

Nothing requires this package. It is the optional fast path behind alberta-buck. Everything here has a pure-Python equivalent in alberta_buck.wallet, which remains the executable specification -- this package is proven bit-identical to it by golden vectors, so choosing it cannot change a single emitted byte. It is only faster.

pip install alberta-buck            # pure Python, works everywhere
pip install alberta-buck[kernel]    # adds this, where a wheel exists

Selection

At call time, via BUCK_IDENTITY_BACKEND:

value	behaviour
unset	use the kernel when importable, else pure Python
kernel	require the kernel; ImportError if absent
py	force the pure-Python path

One wheel per platform

The extension is built abi3-py311, so a single wheel serves every CPython from 3.11 onward -- no rebuild for 3.13, 3.14 and beyond.

Three of the four modules share one shared object: buck-identity, buck-wallet and buck-registry compile into a single cdylib with three #[pymodule] entry points. Shipping them separately would triple 1.5 MB for nothing, so each module loads the same file under its own name -- CPython derives the init symbol (PyInit_buck_wallet) from the last dotted component, not from the filename. Installed size is 2.0 MB rather than 4.9 MB.

Status

0.1.0, prototype. Unaudited cryptographic software. It has been checked for agreement with a reference implementation, which is not the same as having been checked for security.
