Description

This update introduces Constantinople fork at block 6464300 in Sokol network.

Solution

1. Update Parity node to 2.2.5-beta using the guide.
2. Update poa-chain-spec/spec.json - add Constantinople's transitions to engine.params section.
3. Organize the HF on block 6464300.

Instructions

You should be running parity version >= 2.2.5-beta. If you're still running 2.2.1 (or older), please follow this guide first to upgrade: https://github.com/poanetwork/poa-devops/blob/master/docs/Update-parity-version.md

To complete the hardfork you should follow this instruction that will replace spec.json on your 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: "sokol"

• on STEP 3 (create/edit hosts file...) please double-check that you're using your SOKOL 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 6464300 spec.json

You should see:
