RSK Node Updates

Sign up for our RSK Node update notifications. We will use your email only for the purpose of keeping your application connected to the most recent version of the node.

How to update

1. Download rskj

Download the latest release from the Github repo.

2. Update jar file

Note that PREVIOUS and NEW refer to version numbers.

cd /usr/share/rsk
sudo service rsk stop
sudo mv rsk.jar rsk-PREVIOUS.jar
sudo mv rskj-core-NEW-all.jar rsk.jar

3. Clean up log directory

This step is optional.

sudo mkdir /var/log/rsk/PREVIOUS/
sudo mv /var/log/rsk/rsk* /var/log/rsk/PREVIOUS/
sudo service rsk start

4. Validate service is running normally

Check logs:

tail -f /var/log/rsk/rsk.log

Check that Blockchain is moving forward, and adding blocks:

curl -s -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"eth_blockNumber", "params": {},  "id":123}' http://127.0.0.1:4444 | jq .result | tr -d '"' | awk '{print "printf \"%d\\n\" "$0}' | sh

If you run this command a few times and the block number is increasing, it means it is syncing correctly too.
