Introduction

All state transition functions and accompanying data structures described in the product specification BIP15: Proposing Bancor 3 are the core system level operations of this library.

Notation

Code snippets appearing in this style are to be interpreted as Python 3 code.

Formatting & Style

Code is formatted according to PEP8, which is the official Python style guide. In order to overcome the burden on the developers to fix formatting, we use Black which reports on format errors and automatically fixes them.
