A Python implementation of correct-by-construction consensus protocols, including Casper the Friendly Ghost for blockchain.
Casper CBC is a Python implementation of correct-by-construction consensus protocols, which are designed with formal verification to ensure safety and fault tolerance. It provides simulations for protocols like Casper the Friendly Ghost, enabling researchers and developers to study and experiment with decentralized agreement mechanisms. The project focuses on provably secure consensus for blockchain and other distributed systems.
Blockchain researchers, distributed systems engineers, and protocol developers interested in formal methods and consensus algorithm design.
It offers a research-grade, extensible framework for simulating and analyzing correct-by-construction consensus protocols with visualizations, unique for its emphasis on provable safety and modular implementation.
Casper CBC is a Python implementation of a class of correct-by-construction (CBC) consensus protocols, which are designed to be provably safe and fault-tolerant from the ground up. It currently includes implementations for Casper the Friendly Ghost (a blockchain consensus protocol) and Casper the Friendly Binary Consensus Protocol, serving as a research and simulation platform for novel consensus mechanisms.
The project emphasizes a formal, research-driven approach to consensus, prioritizing provable correctness and modular design to advance the understanding and development of decentralized agreement protocols.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Built with correct-by-construction principles to ensure provable safety and fault tolerance, as emphasized in the linked research papers and project philosophy.
Implements consensus for various data structures like binary, blockchain, integer, order, and sharding, enabling diverse experimentation as shown in the simulation commands.
Allows customization of validators, rounds, and message-passing modes (rand, rrob, full) via config.ini and command-line options, detailed in the README.
Generates graphs and GIFs saved in graphs/graph_num_0/ to visualize consensus execution and validator behavior, aiding in analysis and debugging.
The pre-v1.0 codebase is under active development with significant breaking changes expected, as warned in the README, making it unreliable for long-term projects.
Key sections like 'Write Simulations' are marked 'COMING SOON', limiting guidance for extensibility and hindering user adoption beyond basic simulations.
Primarily designed for simulation and research, not optimized for production use, performance, or integration into existing systems, with a limited ecosystem compared to mainstream consensus libraries.
