Description

This update introduces Fixed Constantinople (St.Petersfork) hard fork at block 8582254 in Core network.

Solution

1. Update Parity node to 2.3.2 using the guide.
2. Update poa-chain-spec/spec.json - add Constantinople's transitions to engine.params section.
3. Organize the HF on block 8582254.

Instructions

Follow this guide first to upgrade parity to version 2.3.2: https://github.com/poanetwork/poa-devops/blob/master/docs/Update-parity-version.md

Then follow this instruction that will replace spec.json on your validator node: https://github.com/poanetwork/poa-devops/blob/master/docs/Spec-hardfork.md

• on STEP 2 (create group_vars/all...) use the following parameters:

MAIN_REPO_FETCH: "poanetwork"
GENESIS_BRANCH: "core"

• on STEP 3 (create/edit hosts file...) please double-check that you're using your CORE node's IP address

• on STEP 6 (connect to the node...) after you've done all the checks, also verify HF block number:

grep -n -A2 8582254 spec.json

You should see:

39:    "eip145Transition": 8582254,
40:    "eip1014Transition": 8582254,
41:    "eip1052Transition": 8582254
