econumi-coin

The goal of this blockchain is to change the mining paradigm to doing actual computational work (i.e. scientific experiments similar to GridCoin, machine learning on models to build better models) instead of just hashing and verifying hashes. A similar project to this currently exists called Golem but it written in Python and does not have deep integrations with the Docker Platform.

Design Doc

Read the following design doc to learn more about the design of this product: econumi-spec.md. Also see sprint1.md for an overview of the latest design in action.

Background material

For a primer on bitcoin and cryptocurrencies this is a great read the following resources if you can:

• Mastering Bitcoin: Programming the Open Blockchain
• Bitcoin whitepaper
• Ethereum whitepaper
• Nano whitepaper
• BlackCoin Proof of Stake

MVP (Demo)

• Run a tasks with varying degrees of difficulty as containers and get rewarded for mining
• Verify signed containers via notary in a decentralized way via notary
• Setup peer to peer network and keep a node running (https://github.com/libp2p/go-libp2p)
• Build image, endpoint into blockchain hashmap[image hash][(difficulty, endpoint)]
• Build a way to measure amount of computation and work done on miner (https://github.com/bobrik/collectd-docker)
• Run as systemd background process: https://raspberrypi.stackexchange.com/questions/52052/how-to-run-a-golang-program-in-the-background

Backlog

• GPU support for containers
• Support for Apache Spark on K8s: http://spark.apache.org/releases/spark-release-2-3-0.html
• Incorporate k8s and Calico to run a container with networking across clusters. Run an nginx application that is reachable from another cluster and accessible on the internet.
• Client GUI using React (https://github.com/cgrant/go-react, https://stackoverflow.com/questions/26559557/how-do-you-serve-a-static-html-file-using-a-go-web-server)
• Find a business model (provide a commercial service that will heavily be utilized by businesses)
  • Possible use cases for business
    • Allow financial instutions to be involved in a financial network in exchange for providing compute power to companies. Generate support contracts to get first customers.
    • Virtual Currency for Games, E-Game Tournaments, and Livestreaming - allows game companies to mine and distribute virtual currency paid for by grid consumers
    • Provide computation services for machine learning engines
    • Provide computation services for synthetic browser testing
    • Provide security solution for storing crypto currencies
    • Provide monitoring and management console for servers running blockchain
    • Run p2p services like PeerTube and get compensated: https://github.com/Chocobozzz/PeerTube
• Use anacrolix for peer to peer network (runs on MIT License): https://github.com/anacrolix/torrent
• Crypto SDK to utilize if need to start to build Byzantine Fault Tolerance: https://github.com/tendermint/tendermint

Prerequisites (Install before building)

• Docker CE: Version 17.12.x (link)
• Golang: Version 1.10 (brew install go)
• Glide: Version 0.13.1 (brew install glide)

Getting Started

The easiest way to get started is to clone the repository and create your own env.sh file:

Example env.sh file

export GOPATH=/Users/yongshin/projects/econumi-coin
export PATH=$PATH:$GOPATH/bin
export NODE_ID=3000
export DOCKER_API_VERSION='1.35'
export DATA_DIR=$GOPATH/data

Commands to get started:

# Add ssh key for convenience or insert into .zshrc file
ssh-add -K /Users/yongshin/.ssh/id_rsa
# Get the latest snapshot
git clone git@gitlab.com:econumi/econumi-coin.git econumi-coin
cd econumi-coin
source env.sh
cd src/econumi.org/
# Get all packages from Glide
glide install
cd $GOPATH
make
make start
