JanotChain is an innovative solution to the scalability problem with the Ethereum blockchain. Our mission is to be a leading force in building the Internet of Value, and its infrastructure. We are working to create an alternative, scalable financial system which is more secure, transparent, efficient, inclusive, and equitable for everyone.

JanotChain relies on a system of 150 Masternodes with a Proof of Stake Voting consensus that can support near-zero fee, and 2-second transaction confirmation times. Security, stability, and chain finality are guaranteed via novel techniques such as double validation, staking via smart-contracts, and "true" randomization processes.

Janotchain supports all EVM-compatible smart-contracts, protocols, and atomic cross-chain token transfers. New scaling techniques such as sharding, private-chain generation, and hardware integration will be continuously researched and incorporated into Janotchain's masternode architecture. This architecture will be an ideal scalable smart-contract public blockchain for decentralized apps, token issuances, and token integrations for small and big businesses.

Janotchain provides a client binary called janot for both running a masternode and running a full-node. Building janot requires both a Go (1.7+) and C compiler; install both of these.

Once the dependencies are installed, just run the below commands:

$ git clone https://github.com/janotchain/janotchain 
$ cd janotchain
$ make janot

Alternatively, you could quickly download our pre-complied binary from our github release page

$GENESIS_PATH : location of genesis file you would like to put

export GENESIS_PATH=path/to/genesis.json

• Testnet

curl -L https://raw.githubusercontent.com/janotchain/janotchain/master/genesis/testnet.json -o $GENESIS_PATH

• Mainnet

curl -L https://raw.githubusercontent.com/janotchain/janotchain/master/genesis/mainnet.json -o $GENESIS_PATH

• create a folder to store janotchain data on your machine

export DATA_DIR=/path/to/your/data/folder 
mkdir -p $DATA_DIR/janot

janot init $GENESIS_PATH --datadir $DATA_DIR

If you already had an existing account, import it. Otherwise, please initialize new accounts

export KEYSTORE_DIR=path/to/keystore

     --keystore $KEYSTORE_DIR \
     --password [YOUR_PASSWORD_FILE_TO_LOCK_YOUR_ACCOUNT]

janot account list --datadir ./  --keystore $KEYSTORE_DIR
