Tendermint in Golang

Tendermint is a completely decentralized byzantine consensus protocol suitable for use in cryptocurrencies.

This project is a reference implementation of the protocol.

Submodules

• consensus: core consensus algorithm
• state: application state; mutated by transactions
• blocks: structures of the blockchain
• mempool: gossip of new transactions
• merkle: merkle hash trees
• p2p: extensible P2P networking

Requirements

Go 1.2 or newer.

OpenSSL header files. sudo apt-get install libssl-dev on Debian/Ubuntu //TODO OpenSSL header files for other platforms

###Setting up Golang

Install Go for your platform

Set up environment variables. Go requires certain environment variables to compile code. Set these in your terminal, .profile or .zshrc as appropiate.

export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
export GOPATH=$HOME/gopkg

Build

make get_deps
make

Run

./tendermint daemon --help

Editing your config.json

The file will be create in ~/.tendermint/config.json

There is not official or testnet SeedNode yet. Will updated with an official list of seed nodes.

//TODO Explanation of other config.json fields

{
        "Network": "tendermint_testnet0",
        "LAddr": "0.0.0.0:0",
        "SeedNode": "",
        "DB": {
                "Backend": "leveldb",
                "Dir": "/home/zaki/.tendermint/data"
        },
        "Alert": {
                "MinInterval": 0,
                "TwilioSid": "",
                "TwilioToken": "",
                "TwilioFrom": "",
                "TwilioTo": "",
                "EmailRecipients": null
        },
        "SMTP": {
                "User": "",
                "Password": "",
                "Host": "",
                "Port": 0
        },
        "RPC": {
                "HTTPLAddr": "0.0.0.0:0"
        }
}

You will also to need to have a genesis.json in ~/.tendermint/. This must be the common genesis.json as the network you are joining from the Seed Node

{
    "Accounts": [
        {
            "Address": "6070ff17c39b2b0a64ca2bc431328037fa0f4760",
            "Amount":  200000000
        }
    ],
    "Validators": [
        {
            "PubKey": "01206bd490c212e701a2136eeea04f06fa4f287ee47e2b7a9b5d62edd84cd6ad9753",
            "Amount": 100000000,
            "UnbondTo": [
                {
                        "Address": "6070ff17c39b2b0a64ca2bc431328037fa0f4760",
                        "Amount":  100000000
                }
            ]
        }
    ]
}
