About Rupaya

Rupaya 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.

Rupaya 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.

Rupaya 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 Rupaya'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.

More details can be found at our technical white paper

Building the source

Rupaya provides a client binary called rupaya for both running a masternode and running a full-node. Building rupaya 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 rupaya
$ cd rupaya
$ make rupaya

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

Running rupaya

Running a rupaya masternode

Please refer to the official documentation on how to run a node if your goal is to run a masternode. The recommanded ways of running a node and applying to become a masternode are explained in detail there.

Attaching to the Rupaya test network

We published our test network 2.0 with full implementation of PoSV consensus at If you'd like to experiment with smart contract creation and DApps, you might be interested to give these a try on our Testnet.

In order to connect to one of the masternodes on the Testnet, just run the command below:

$ rupaya attach

This will open the JavaScript console and let you query the blockchain directly via RPC.

Running rupaya locally

Download genesis block

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

export GENESIS_PATH=path/to/genesis.json
  • Testnet
curl -L -o $GENESIS_PATH
  • Mainnet
curl -L -o $GENESIS_PATH

Create datadir

  • create a folder to store rupaya data on your machine
export DATA_DIR=/path/to/your/data/folder 
mkdir -p $DATA_DIR/rupaya

Initialize the chain from genesis

rupaya init $GENESIS_PATH --datadir $DATA_DIR

Initialize / Import accounts for the nodes's keystore

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

export KEYSTORE_DIR=path/to/keystore
Initialize new accounts
rupaya account new \
  --keystore $KEYSTORE_DIR
Import accounts
rupaya  account import [PRIVATE_KEY_FILE_OF_YOUR_ACCOUNT] \
     --keystore $KEYSTORE_DIR \
List all available accounts in keystore folder
rupaya account list --datadir ./  --keystore $KEYSTORE_DIR

Start a node

Environment variables
  • $IDENTITY: the name of your node
  • $PASSWORD: the password file to unlock your account
  • $YOUR_COINBASE_ADDRESS: address of your account which generated in the previous step
  • $NETWORK_ID: the networkId. Mainnet: 499. Testnet: 89
  • $BOOTNODES: The comma separated list of bootnodes. Find them here
  • $WS_SECRET: The password to send data to the stats website. Find them here
  • $NETSTATS_HOST: The stats website to report to, regarding to your environment. Find them here
  • $NETSTATS_PORT: The port used by the stats website (usually 443)
Let's start a node
rupaya  --syncmode "full" \    
    --datadir $DATA_DIR --networkid $NETWORK_ID --port 9050 \   
    --keystore $KEYSTORE_DIR --password $PASSWORD \    
    --rpc --rpccorsdomain "*" --rpcaddr --rpcport 7050 --rpcvhosts "*" \   
    --rpcapi "db,eth,net,web3,personal,debug" \    
    --gcmode "archive" \   
    --ws --wsaddr --wsport 8050 --wsorigins "*" --unlock "$YOUR_COINBASE_ADDRESS" \   
    --identity $IDENTITY \  
    --mine --gasprice 2500 \  
    --bootnodes $BOOTNODES \   
Some explanations on the flags
--verbosity: log level from 1 to 5. Here we're using 4 for debug messages

--keystore: path to your account's keystore created above.
--identity: your full-node's name.
--password: your account's password.
--networkid: our network ID.
--rupaya-testnet: required when the networkid is testnet(89).
--port: your full-node's listening port (default to 9050)
--rpc, --rpccorsdomain, --rpcaddr, --rpcport, --rpcvhosts: your full-node will accept RPC requests at 7050 TCP.
--ws, --wsaddr, --wsport, --wsorigins: your full-node will accept Websocket requests at 8050 TCP.
--mine: your full-node wants to register to be a candidate for masternode selection.
--gasprice: Minimal gas price to accept for mining a transaction.
--targetgaslimit: Target gas limit sets the artificial target gas floor for the blocks to mine (default: 4712388)
--bootnode: bootnode information to help to discover other nodes in the network
--gcmode: blockchain garbage collection mode ("full", "archive")
--synmode: blockchain sync mode ("fast", "full", or "light". More detail:           
--ethstats: send data to stats website
