Block Keeper

System requirements

Configuration	CPU (cores)	RAM (GiB)	Storage	Network
Minimum	8c/16t	64	1 TB NVMe	1 Gbit synchronous unmetered Internet connection
Recommended	12c/24t	128	2 TB NVMe	1 Gbit synchronous unmetered Internet connection

Steps

1. Deploy Block Keeper Wallet
2. Create ansible inventory for Block Keeper node deployment
3. Run ansible playbook against inventory to deploy Block Keeper node
4. Run staking script

Block Keeper Wallet deployment

Prerequisites

• tvm-cli command line tool installed
• Sponsor Wallet with enough NACKL tokens deployed

See this guide explaining how to install CLI and deploy Sponsor Wallet

Configure tvm-cli

To set appropriate network use next command

tvm-cli config --url shellnet.ackinacki.org/graphql

In this case we are using Shellnet network

Deploy

To deploy Block Keeper Wallet use Shell script scripts/create_block_keeper_wallet.sh You have to provide necessary arguments:

• Sponsor Wallet address from where NACKL tokens will be sent
• Wallet keys file. File with the owner's keys of Sponsor Wallet
• Master keys file output path. Path to the file with keys for Block Keeper Wallet, which will be created
• Service keys file output path. Path to the file with Service Keys for Block Keeper Wallet, which will be created

cd scripts
create_block_keeper_wallet --help

After successful script completion save you node id and master key file path It will be used in ansible playbook

Ansible

Prerequisites

• SSH access to servers
• Docker with compose plugin must be installed

Prepare you inventory

Here is basic inventory for shellnet node deployment

all:
  vars:
    ansible_port: 22
    ansible_user: ubuntu
    #Path to store deployment files
    ROOT_DIR: /home/user/deployment
    #Path to store data
    MNT_DATA: /home/user/data
    BIND_PORT: 8500
    BIND_API_PORT: 8600
    BIND_MESSAGE_ROUTER_PORT: 8700
    BIND_GOSSIP_PORT: 10000
    NODE_IMAGE: teamgosh/ackinacki-node
    GQL_IMAGE: teamgosh/ackinacki-gql-server
    REVPROXY_IMAGE: teamgosh/ackinacki-live
    BK_DIR: "{{ ROOT_DIR }}/block-keeper"
    BK_DATA_DIR: "{{ MNT_DATA }}/block-keeper"
    BK_LOGS_DIR: "{{ MNT_DATA }}/logs-block-keeper"
    GOSSIP_SEEDS:
      - shellnet-0.ackinacki.org:10000
      - shellnet-1.ackinacki.org:10000
      - shellnet-2.ackinacki.org:10000
      - shellnet-3.ackinacki.org:10000
      - shellnet-4.ackinacki.org:10000
      - YOUR-NODE-ADDRESS:10000
    NODE_STORAGE_LIST:
      - http://shellnet-0.ackinacki.org/storage/node/
      - http://shellnet-1.ackinacki.org/storage/node/
      - http://shellnet-2.ackinacki.org/storage/node/
      - http://shellnet-3.ackinacki.org/storage/node/
      - http://shellnet-4.ackinacki.org/storage/node/
      - http://YOUR-NODE-ADDRESS/storage/node/
    MASTER_KEY: PATH_TO_MASTER_KEY
    NODE_CONFIGS:
      - "zerostate"
      - "blockchain.conf.json"

block_keepers:
  hosts:

    YOUR-NODE-ADDRESS:
      NODE_ID: NODE_ID
      HOST_PUBLIC_IP: YOUR-NODE-PUBLIC-ADDRESS
      HOST_PRIVATE_IP: YOUR-NODE-PRIVATE-ADDRESS

Put your configuration data to inventory and be ready to run playbook

In case of testing you can use ansible-playbook dry run

ansible-playbook -i test-inventory.yaml ansible/node-deployment.yaml --check --diff

If all is good you could run ansible

ansible-playbook -i test-inventory.yaml ansible/node-deployment.yaml --check --diff

Check docker containers

docker ps
#OR
docker compose ps

Check node logs

tail -f $MNT_DATA/logs-block-keeper/node.log

Staking

Prerequisites

• Master keys file
• BLS keys file

BLS keys file could be found at {{ BK_DIR }}/bk-configs/ folder. BK_DIR is a variable from the ansible inventory BLS keys file format - bk{{ NODE_ID }}_bls.keys.json

Run the script

staking path/to/master-keys-file path/to/bls-keys-file
