Release date: 2021-03-20 UTC Docker TAG: iconloop/prep-node: 20210314.0, 2021-03-20 18:00:00 UTC

The following updates describe the latest improvements in each software package, which uses the following version sequence: loopchain 2.7.8, icon-service 1.8.10, icon-rpc-server 1.6.2, and rewardcalculator 1.2.6. See upgrades and fixes for information about updating to the latest release of ICON blockchain-related implementations in the package.

To upgrade your docker, set your docker tag to iconloop/prep-node in your docker-compose.yml. For this upgrade, it is necessary to bring the node down and up, due to changes. Each node needs to be careful not to cause problems in the consensus process:

docker-compose pull
docker-compose down
docker-compose up -d

ICON Service 1.8.10

  • Added a function to implement rate limit based on 'from address'

}

# resetTime: gathering tx for 5 second (default: 5)
# threshold: blocking the address if the same address is sending more than 200 txs
# banTime: the address will be banned for 300 secs
