Bor node

Requirements for Polygon network

• memory: 64Gb (minimum)
• disk: 3Tb SSD (require periodically prune state) - you can use less if you prune more often, but you still need at least 2TB.

Installation

Set in the .env file:

• DOMAIN= - the domain name to be used in traefik;
• HEIMDALL_ETH_RPC_URL= - your Ethereum RPC.

You can also set a list of allowed IP addresses there and addresses to treat as local. Rename example.env to .env:

mv example.env .env

Start node (If you do not use traefik, specify the compose file with the -f docker-compose.no-proxy.yml):

docker-compose build
docker-compose up -d rabbitmq heimdalld heimdallr bor

To see the sync status run: curl -X POST --data '{"jsonrpc": "2.0", "id": 1, "method": "eth_syncing"}' -H 'Content-Type: application/json' -s https://${DOMAIN}/bor-http/

• currentBlock - your node current height;
• highestBlock - network height.

Upgrade

Periodically check for new versions. if there is a release, then you need to update the tag (BOR_TAG) in the environment file.

docker-compose build
docker-compose pull
docker-compose up -d rabbitmq heimdalld heimdallr bor

Pruning

Use it if the size is approaching 1.7Tb. At least 150 GB must be free for successful pruning.

docker-compose stop bor
docker-compose up prune-bor
docker-compose rm prune-bor 
docker-compose up -d bor
