Release Status

Here are the software versions we use:

• MainNet: v0.5.0
• TestNet: v0.5.0-rc10

Join MainNet Alpha

1. Pull the docker image:

docker pull iotex/iotex-core:v0.5.0

Please check if the docker image digest is 28677428d15c858484176ca70b93dae5fd8d621a299a769706faaf669e2095e7.

2. Set the environment with the following commands:

mkdir -p ~/iotex-var
cd ~/iotex-var

export IOTEX_HOME=$PWD

mkdir -p $IOTEX_HOME/data
mkdir -p $IOTEX_HOME/log
mkdir -p $IOTEX_HOME/etc

curl https://raw.githubusercontent.com/iotexproject/iotex-bootstrap/master/config_mainnet.yaml > $IOTEX_HOME/etc/config.yaml
curl https://raw.githubusercontent.com/iotexproject/iotex-bootstrap/master/genesis_mainnet.yaml > $IOTEX_HOME/etc/genesis.yaml

3. Edit $IOTEX_HOME/etc/config.yaml, look for externalHost and producerPrivKey, uncomment the lines and fill in your external IP and private key.

4. (Optional) If you prefer to start from a snapshot, run the following commands:

curl -L https://t.iotex.me/mainnet-data-latest > $IOTEX_HOME/data.tar.gz
tar -xzf data.tar.gz

We will update the snapshot once a day. If you plan to run your node as a gateway, please use the snapshot with index data: https://t.iotex.me/mainnet-data-with-idx-latest.

5. Run the following command to start a node:

docker run -d --restart on-failure --name iotex \
        -p 4689:4689 \
        -p 8080:8080 \
        -v=$IOTEX_HOME/data:/var/data:rw \
        -v=$IOTEX_HOME/log:/var/log:rw \
        -v=$IOTEX_HOME/etc/config.yaml:/etc/iotex/config_override.yaml:ro \
        -v=$IOTEX_HOME/etc/genesis.yaml:/etc/iotex/genesis.yaml:ro \
        iotex/iotex-core:v0.5.0 \
        iotex-server \
        -config-path=/etc/iotex/config_override.yaml \
        -genesis-path=/etc/iotex/genesis.yaml

Now your node should be started successfully.

If you want to also make your node be a gateway, which could process API requests from users, use the following command instead:

docker run -d --restart on-failure --name iotex \
        -p 4689:4689 \
        -p 14014:14014 \
        -p 8080:8080 \
        -v=$IOTEX_HOME/data:/var/data:rw \
        -v=$IOTEX_HOME/log:/var/log:rw \
        -v=$IOTEX_HOME/etc/config.yaml:/etc/iotex/config_override.yaml:ro \
        -v=$IOTEX_HOME/etc/genesis.yaml:/etc/iotex/genesis.yaml:ro \
        iotex/iotex-core:v0.5.0 \
        iotex-server \
        -config-path=/etc/iotex/config_override.yaml \
        -genesis-path=/etc/iotex/genesis.yaml \
        -plugin=gateway

6. Make sure TCP ports 4689, 8080 (also 14014 if used) are open on your firewall and load balancer (if any).

Join TestNet

There's almost no difference to join TestNet, but in step 2, you need to use the config and genesis files for TestNet:

curl https://raw.githubusercontent.com/iotexproject/iotex-bootstrap/master/config_testnet.yaml > $IOTEX_HOME/etc/config.yaml
curl https://raw.githubusercontent.com/iotexproject/iotex-bootstrap/master/genesis_testnet.yaml > $IOTEX_HOME/etc/genesis.yaml

In step 4, you need to use the snapshot for TestNet: https://t.iotex.me/testnet-data-latest and https://t.iotex.me/testnet-data-with-idx-latest.

In step 5, you need to replace the docker image tag in the command with v0.5.0-rc10.

Interact with Blockchain

You can install ioctl (a command-line interface for interacting with IoTeX blockchain)

curl https://raw.githubusercontent.com/iotexproject/iotex-core/master/install-cli.sh | sh

You can point ioctl to your node (if you enable the gateway plugin):

ioctl config set endpoint localhost:14014 --insecure

Or you can point it to our nodes:

• MainNet secure: api.iotex.one:443
• MainNet insecure: api.iotex.one:80
• TestNet secure: api.testnet.iotex.one:443
• TestNet insecure: api.testnet.iotex.one:80

If you want to set an insecure endpoint, you need to add --insecure option.

Generate key:

ioctl account create

Get consensus delegates of current epoch:

ioctl node delegate

Refer to CLI document for more details.

Other Commonly Used Commands

Claim reward:

ioctl action claim ${amountInRau} -l 10000 -p 1 -n ${pendingNonce} -s ${ioAddress|alias}

Exchange to ERC20 on Ethereum via Faucet:

ioctl action invoke io1pcg2ja9krrhujpazswgz77ss46xgt88afqlk6y ${amountInRau} -s ${ioAddress|alias} -l 400000 -p 1 -b d0e30db0

Besides ioctl, we also provide a tool named "bookkeeper" to help calculate the reward distribution for voters by epoch. Refer to bookkeeper instruction for more details.

Operate Your Node

Checking Node log

Container logs can be accessed with the following command.

docker logs iotex

Content can be filtered with:

docker logs -f --tail 100 iotex |grep --color -E "epoch|height|error|rolldposctx"

Stop and remove container

When starting the container with --name=iotex, you must remove the old container before a new build.

docker stop iotex
docker rm iotex

Pause and Restarting container

Container can be "stopped" and "restarted" with:

docker stop iotex
docker start iotex
