Istanbul activation on CORE

POA Core Network Updates
#1

Dear @poa-validators

We are going to activate Istanbul hard fork on Core network at block 12598600 (Thursday, 19-Dec-2019 07:00 UTC).

For that, we need to update both Parity (to v2.6.5) and spec.json. The spec file of Core network is updated for the HF.

Please follow the steps below:

  1. ssh login to your node
  2. stop parity service
sudo systemctl stop poa-parity
  1. switch to home directory (NOTE: if you’re updating a bootnode, path is /home/bootnode)
cd /home/validator
pwd

output should be

/home/validator
  1. remove older backups
sudo rm -rf backups-version
  1. create a new backup
sudo mkdir backups-version
sudo touch backups-version/BEFORE-2.6.5
BKPFLDR="backups-version/$(date '+%Y%m%dT%H%M%S' -u)"
sudo mkdir -p "$BKPFLDR"
sudo mv parity spec.json "$BKPFLDR"
  1. switch to validator user (NOTE: if you’re updating a bootnode, username should be bootnode)
sudo -i -u validator
  1. download new parity binary
curl -LO 'https://releases.parity.io/ethereum/v2.6.5/x86_64-unknown-linux-gnu/parity'
  1. check binary integrity
echo '62762f424ffcc9ea939f3e09904d64600c4966045a865cfd94f23cf967213a0d parity' | sha256sum -c

output should be

parity: OK
  1. set permission to execute the binary
chmod +x parity
  1. download new spec file
curl -LO 'https://raw.githubusercontent.com/poanetwork/poa-chain-spec/core/spec.json'
  1. check that new spec contains a transition block set to 12598600
grep 12598600 spec.json

output should be

    "eip1283Transition": 12598600,
    "eip1344Transition": 12598600,
    "eip1706Transition": 12598600,
    "eip1884Transition": 12598600,
    "eip2028Transition": 12598600
          "12598600": {
          "12598600": {
          "12598600": {
          "12598600": {
  1. login back to sudo-enabled user
exit
  1. restart services
sudo systemctl start poa-parity && sleep 10 && sudo systemctl restart poa-netstats
  1. check that your node is “green” in netstats https://core-netstat.poa.network (this may take a couple of minutes)
  2. wait to see if your node produces new blocks https://blockscout.com/poa/core

Istanbul activation on POA Core was successful! The testing contract shows 800 gas consumption for SLOAD opcode as expected. The two validators (John D. Storey and Oxana Kunets) are out of consensus since they are not updated.

Please update your nodes @johndangerstorey @oxanakunets

After you update, please check your node’s logs. If you see any errors there, follow the same procedure as above, but after step 11 before step 12 additionally run

./parity --config node.toml db kill

It will clear the blockchain database and start a resync which can take some time, so steps 14, 15 will not work immediately.

John D. Storey and Oxana Kunets POA Core Validator nodes are updated as seen on Netstats page. Congratulations, Istnabul activion on POA Core is complete and a success!
