Dear @kovan-validators,
Recently, Ethereum Mainnet miners increased block gas limit up to 12.5M gas/block (https://ethstats.net/). To keep smart contracts functionality of Kovan compatible with ETH, we propose to increase block gas limits in Kovan as well.
You can follow these steps to update the limit on your Kovan validator node.
-
Connect to your Kovan validator node.
-
Create a backup copy of current version of parity config
sudo cp -a /home/validator/node.toml /home/validator/node.toml.bkp
- Check that backup is created
ls /home/validator
you should see node.toml.bkp
in the list.
- Open config file in your favorite text editor (I use
nano
here as an example)
sudo nano /home/validator/node.toml
- Look for
gas_floor_target
configuration option, it should be in themining
section of the file:
...
[mining]
...
gas_floor_target = "10000000"
...
-
Change the value from
"10000000"
to"12500000"
-
Save the file and exit (in
nano
: press CTRL+X and confirm YENTER) -
Restart parity service and netstat agent
sudo systemctl restart poa-parity && sleep 10 && sudo systemctl restart poa-netstats
-
Check in netstats (https://kovan-netstat.poa.network) that your node is “green” and in sync with others.
-
In case something goes wrong you should be able to rollback by restoring original configuration file from the backup
sudo cp -a /home/validator/node.toml.bkp /home/validator/node.toml
sudo systemctl restart poa-parity && sleep 10 && sudo systemctl restart poa-netstats
