Description: Core system of BBc-1 (Beyond Blockchain One)
        ===========================================
        This project is a Python-based reference implementation of BBc-1, a trustable system of record keeping beyond blockchains.
        
        The design paper (white paper) and the analysis paper are available [here](https://beyond-blockchain.org/public/bbc1-design-paper.pdf) and [here](https://beyond-blockchain.org/public/bbc1-analysis.pdf). BBc-1 is inspired from blockchain technologies like Bitcoin, Ethereum, Hyperledger projects, and so on.
        BBc-1 is a simple but reliable distributed ledger system in contrast with huge and complicated existing blockchain platforms.
        The heart of BBc-1 is the transaction data structure and the relationship among transactions, which forms a graph topology.
        A transaction should be signed by the players who are the stake holders of the deal. BBc-1 achieves data integrity and data transparency by the topology of transaction relationship and signatures on transactions. Simply put, BBc-1 does not have *blocks*, and therefore, requires neither mining nor native cryptocurrency.
        BBc-1 can be applied to both private/enterprise use and public use. BBc-1 has a concept of *domain* for determining a region of data management. Any networking implementation (like Kademlia for P2P topology management) can be applied for each domain.
        Although there are many TODOs in BBc-1, this reference implementation includes most of the concept of BBc-1 and would work in private/enterprise systems. When sophisticated P2P algorithms are ready, BBc-1 will be able to support public use cases.
        
        Every directory includes README.md. Please read it for the details. Furthermore, directory docs/ includes documents and slide decks (PDF) that explain the design of the BBc-1 and its implementation.
        
        # Environment
        
        * Python
            - Python 3.6.0 or later
        
        * tools for macOS by Homebrew
            ```
            brew install libtool automake geth solidity pkg-config
            ```
        
        * tools for Linux (Ubuntu 16.04 LTS)
            ```
            sudo apt-get install -y git tzdata openssh-server python3 python3-dev python3-venv libffi-dev net-tools autoconf automake libtool libssl-dev make
            ```
        
        
        # Quick start
        
        ## Documents
        Some documents are available in docs/.
        * [how_to_use_in_nat_environment.md](docs/how_to_use_in_nat_environment.md)
        
        
        ## From source code in github
        1. Install tools (libtool, automake)
        2. Install python and pip
        3. Clone this project
        4. Prepare OpenSSL-based library in the root directory
            ```
            sh prepare.sh
            ```
        5. Install dependencies by the following command.
            ```
            pip install -r requirements.txt
            ```
        6. Start bbc_core.py on a terminal
            ```
            cd core
            python bbc_core.py
            ```
        7. Start a sample app in another terminal
            ```
            cd examples
            python file_proof.py arg1 arg2..
            ```
        
        
        ## Use pip
        1. Install tools (libtool, automake)
        2. Install python and pip
        3. Install BBc1 by pip
            ```
            pip install bbc1
            ```
        
        ## Use docker (See README.md in docker/)
        0. Install docker on your host
        1. Clone this project
        2. Build docker image
            If you want source codes in your container,
            ```
            cd docker
            ./docker-bbc1.sh gitbuild
            ```
            or, if you just want to use BBc-1,
            ```
            cd docker
            ./docker-bbc1.sh pipbuild
            ```
        3. Run a docker container
            ```
            ./docker-bbc1.sh start
            ```
        4. Log in to the container
            ```
            ./docker-bbc1.sh shell
            ```
            or
            ```
            ssh -p 10022 root@localhost
            ```
            The initial password is "bbc1".
        
        ### working directory
        The working directory of BBc-1 on the docker container is mounted on docker/data/.bbc1/. You will find a config file, ledger DB and file storage directory in the working directory.
