Validators

This guide will instruct you on how to set up a validator node on the AI Network.
​⚠
 Warning: You may earn rewards by running validators, but if you get slashed by your mistake, you can lose your money and reputation.
Validator Parameters
Annual reward rate: ~8% + transaction fees (varies)
Unbonding period: 7 days
Payout frequency: Every block (~20 seconds)
Initial Set-up
Requirements
Minimum stake requirements
None for validators without proposal rights. If you'd like to run a proposer node, contact us at [email protected].
Hardware requirements
16 CPUs
64GB Memory
2TB Disk (SSD preferably)
Example GCP Instance: c2-standard-16
Networking requirements
Reserve a static, publicly routable IPv4 IP address for your node.
Your firewalls should expose TCP/5000 and TCP/8080
OS requirements
Ubuntu 18.04 or above
Running a Validator
While AI Network is in beta testing mode, we're only allowing whitelisted nodes to participate as validators. Please contact [email protected] if you're interested.
1. Git clone & install dependencies
git clone https://github.com/ainblockchain/ain-blockchain.git
cd ain-blockchain
yarn install
2. Start a node
Using a keystore file
BLOCKCHAIN_CONFIGS_DIR=blockchain-configs/mainnet-prod \
    STAKE=10000 \
    ACCOUNT_INJECTION_OPTION=keystore \
    KEYSTORE_FILE_PATH=/path/to/keystore/file \
    nohup node --max-old-space-size=55000 client/index.js >/dev/null 2>error_logs.txt &
Using a mnemonic phrase
BLOCKCHAIN_CONFIGS_DIR=blockchain-configs/mainnet-prod \
    STAKE=10000 \
    ACCOUNT_INJECTION_OPTION=mnemonic \
    nohup node --max-old-space-size=55000 client/index.js >/dev/null 2>error_logs.txt &
​
3. Inject your account into your node
Using a Keystore file
The following command requires two inputs: the path of your Keystore file and its password.
node inject_account_gcp.js <NODE_ENDPOINT_URL> --keystore
Using a mnemonic phrase
The following command requires two inputs: a mnemonic phrase and an account index. If you do not enter an account index, it is set to the default value of 0.
node inject_account_gcp.js <NODE_ENDPOINT_URL> --mnemonic
4. Check out your node on the blockchain explorer!

Running a Validator with Docker
Instead of starting from a git clone, you can use a pre-built docker image from Docker Hub.
1. Pull Docker image from Docker Hub
docker pull ainblockchain/ain-blockchain:latest
2. Run Docker image
Using a Keystore file
docker run -e ACCOUNT_INJECTION_OPTION=keystore \
    -e SYNC_MODE=peer -e STAKE=10000 -e SEASON=mainnet \
    --network="host" -d ainblockchain/ain-blockchain:latest
Using a mnemonic phrase
If you executed the second command, you don't need to manually inject your account into your node.
docker run -e ACCOUNT_INJECTION_OPTION=mnemonic \
    -e SYNC_MODE=peer -e STAKE=10000 -e SEASON=mainnet \
    --network="host" -d ainblockchain/ain-blockchain:latest
    
docker run -e ACCOUNT_INJECTION_OPTION=mnemonic -e MNEMONIC="your mnemonic" \
    -e SYNC_MODE=peer -e STAKE=10000 -e SEASON=mainnet \
    --network="host" -d ainblockchain/ain-blockchain:latest
3. Inject your account into your node
Using a Keystore file
The following command requires two inputs: the path of your Keystore file and its password.
node inject_account_gcp.js <NODE_ENDPOINT_URL> --keystore
Using a mnemonic phrase
The following command requires two inputs: a mnemonic phrase and an account index. If you do not enter an account index, it is set to the default value of 0.
node inject_account_gcp.js <NODE_ENDPOINT_URL> --mnnemonic
