Binary
This guide shows how to run a TomoChain masternode in testnet and
mainnet without the need of using Docker and tmn
.
Install Golang¶
- Reference: https://golang.org/doc/install
- Set environment variables
- Supports Go 1.10, 1.11, 1.12
export GOROOT=$HOME/usr/local/go export GOPATH=$HOME/go
Prepare tomo client software¶
Build from source code¶
Create new directory for the project
mkdir -p $GOPATH/src/github.com/ethereum/ cd $GOPATH/src/github.com/ethereum/
- Download source code and build
git clone https://github.com/tomochain/tomochain.git go-ethereum
cd go-ethereum
- Checkout the latest version (e.g v1.5.4)
git pull origin --tags git checkout v1.4.1
- Build the project
make all
- Binary file should be generated in build folder
$GOPATH/src/github.com/ethereum/go-ethereum/build/bin
alias tomo=$GOPATH/src/github.com/ethereum/go-ethereum/build/bin/tomo
Download TomoChain binary from Github release page¶
Download tomo binary from our releases page
alias tomo=path/to/tomo/binary
Download genesis block¶
$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/tomochain/tomochain/master/genesis/testnet.json -o $GENESIS_PATH
- Mainnet
curl -L https://raw.githubusercontent.com/tomochain/tomochain/master/genesis/mainnet.json -o $GENESIS_PATH
Create datadir¶
- create a folder to store tomochain data on your machine
export DATA_DIR=/path/to/your/data/folder mkdir -p $DATA_DIR/tomo
Initialize the chain from genesis¶
tomo 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¶
tomo account new \ --password [YOUR_PASSWORD_FILE_TO_LOCK_YOUR_ACCOUNT] \ --keystore $KEYSTORE_DIR
Import accounts¶
tomo account import [PRIVATE_KEY_FILE_OF_YOUR_ACCOUNT] \ --keystore $KEYSTORE_DIR \ --password [YOUR_PASSWORD_FILE_TO_LOCK_YOUR_ACCOUNT]
List all available accounts in keystore folder¶
tomo account list --datadir $DATA_DIR --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: 88. 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¶
tomo --syncmode "full" \ --datadir $DATA_DIR --networkid $NETWORK_ID --port 30303 \ --keystore $KEYSTORE_DIR --password $PASSWORD \ --identity $IDENTITY \ --mine --gasprice 250000000 \ --bootnodes $BOOTNODES \ --ethstats $IDENTITY:$WS_SECRET@$NETSTATS_HOST:$NETSTATS_PORT
If you are a dapp developer, you should open RPC and WS apis:
tomo --syncmode "full" \ --datadir $DATA_DIR --networkid $NETWORK_ID --port 30303 \ --keystore $KEYSTORE_DIR --password $PASSWORD \ --rpc --rpccorsdomain "*" --rpcaddr 0.0.0.0 --rpcport 8545 --rpcvhosts "*" \ --rpcapi "db,eth,net,web3,personal,debug" \ --gcmode "archive" \ --ws --wsaddr 0.0.0.0 --wsport 8546 --wsorigins "*" --unlock "$YOUR_COINBASE_ADDRESS" \ --identity $IDENTITY \ --mine --gasprice 250000000 \ --bootnodes $BOOTNODES \ --ethstats $IDENTITY:$WS_SECRET@$NETSTATS_HOST:$NETSTATS_PORT
Some explanations on the flags¶
--verbosity: log level from 1 to 5. Here we're using 4 for debug messages --datadir: path to your data directory created above. --keystore: path to your account's keystore created above. --identity: your full-node's name. --password: your account's password. --networkid: our network ID. --port: your full-node's listening port (default to 30303) --rpc, --rpccorsdomain, --rpcaddr, --rpcport, --rpcvhosts: your full-node will accept RPC requests at 8545 TCP. --ws, --wsaddr, --wsport, --wsorigins: your full-node will accept Websocket requests at 8546 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: https://github.com/tomochain/tomochain/blob/master/eth/downloader/modes.go#L24) --ethstats: send data to stats website --tomo-testnet: required when the networkid is testnet(89) --store-reward: store reward report

Troubleshoot¶
If your node seems run smooth with no error logs but still get slash frequently. You need to check system time on your node, your system time have to be synced from NTP server
E.g:
$ timedatectl Local time: Fri 2019-07-26 05:57:40 CEST Universal time: Fri 2019-07-26 03:57:40 UTC RTC time: Fri 2019-07-26 03:58:01 Time zone: Europe/Berlin (CEST, +0200) Network time on: yes NTP synchronized: no RTC in local TZ: no
NTP synchronized: no
means your node does not use NTP, you have to enable it.
