Bamboo

Bamboo is a minimalist implementation of a layer 1 cryptocurrency similar to Bitcoin. It is designed with utmost simplicity and user friendliness in mind and is written from the ground up in C++ — it isn't yet another re-packaging of existing open-source blockchain code (where's the fun in that?!).

Circulation

Bamboo is minted by miners who earn rewards. Mining payments occur using the following algorithm, which yields a total final circulation of 100M BMB

50 BMB per block until block 1M
25 BMB per block for blocks 1M to 2M
12.5 BMB per block for blocks 2M to 4M

Technical Implementation

Bamboo is written from the ground up in C++. We want the Bamboo source code to be simple, elegant, and easy to understand. Rather than adding duct-tape to an existing currency, we built Bamboo from scratch with lots of love. There are a few optimizations that we have made to help further our core objectives:

Switched encryption scheme from secp256k1 (which is used by ETH & BTC) to ED25519 -- results in 8x speedup during verification and public keys half the size.
Up to 25,000 transactions per block, 90 second block time

Getting Started

Windows: Only binaries are available for windows they can be downloaded here:

https://github.com/mr-pandabear/bamboo/releases/download/v0.2-miner-alpha/bamboo-win-update.zip

Run keygen.exe, this generates a keys.json file in the same folder as miner.exe, copy this file and keep it safe.
Run miner.exe, the miner will start running and should indicate that it is loading blocks to solve.

Mac OSX build pre-requirements

brew install leveldb
brew install cmake
pip3 install conan

Linux install pre-requirements

sudo apt-get update
sudo apt-get -y install make  
sudo apt-get -y install cmake  
sudo apt-get -y install automake
sudo apt-get -y install libtool
sudo apt-get -y install python3-pip
sudo apt-get -y install libleveldb-dev
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.6
sudo pip3 install conan

Building

git clone https://github.com/mr-pandabear/bamboo.git
cd bamboo
git checkout master
mkdir build
cd build
conan install ..
cd ..
cmake .

To compile the miner run the following command:

make miner

You will also need the keygen app to create a wallet for your miner:

make keygen

To compile the node server:

make server

Usage

Start by generating keys.json.

./bin/keygen

Keep a copy of this file in a safe location -- it contains pub/private keys to the wallet that the miner will mint coins to. If you lose this file you lose your coins. We recommend keeping an extra copy on a unique thumbdrive (that you don't re-use) the moment you generate it.

To start mining:

./bin/miner

To host a node:

./bin/server

NOTE: you will need to make a folder ~/bamboo/data to store the nodes data
