SUPPORTED PLATFORMS

We support running a full node on Ubuntu 22.04 LTS.

MINIMUM HARDWARE REQUIREMENTS

  • 8 cores of CPU and 16 gigabytes of memory (RAM).
  • fixed size hard disk, 2TB or elastic volumes, 1TB.

SOFTWARE PREREQUISITES

  • install docker

https://docs.docker.com/engine/install/#server

  • install docker compose-plugin

https://docs.docker.com/compose/install/compose-plugin/#installing-compose-on-linux-systems

STORE THE NODE DATA IN A DIFFERENT DIRECTORY(optional)

The default node data directory(./node-data) is in the same directory as the docker-compose.yml file. Mount a new host folder,replace the path "./node-data" in docker-compose.yml with new directory.

RUNNING FULL NODE

  • Build docker image locally(optional)
make build
  • Run node(If the docker image does not exist, pull the image from Docker Hub automaticlly.)
docker-compose up -d
  • Stop the full node
docker-compose down
  • Download the latest node data archive file(recommend, Default automatic snapshot time is 03:00 UTC)
nohup sudo curl -SL https://dl.caduceus.foundation/downloads/node-data-$(date -u +'%Y%m%d').tar.gz -O ./node-data.tar.gz &

or
 
nohup sudo curl -SL https://dl.caduceus.foundation/downloads/node-data-$(date  -u -d yesterday  +'%Y%m%d').tar.gz -O ./node-data.tar.gz &



sudo tar -xzvf ./node-data-${YYYYMMDD}.tar.gz 

replace the YYYYMMDD with the date in the downloaded file name.

docker-compose down

sudo cp -r ./node-data/node0 ./node-data/node0.bak

mv ./node-data/node0/data  ./node-data/node0/data.bak
mv ./data/ ./node-data/node0/
sudo cp ./node-data/node0/data.bak/priv_validator_state.json ./node-data/node0/data 

docker-compose up -d

CHECK THE LAST SYNCED BLOCK NUMBER

If you change the default data directory for node, replace the path "./node-data" with your new directory. or run the command in the same directory as the docker-compose.yml file. You maybe need to wait about serval minutes, and then the node will sync blocks and generate committed logs.

tail ./node-data/node0/stdout-cmpd.txt -f | grep Committed

TEST RPC

curl -X POST -H 'Content-Type: application/json' --data '{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["latest", true],"id":1}' http://127.0.0.1:26658
