Everything You Need to Know About the Ethereum Fork Called Constantinople
Most Ethereum users need to do nothing for the Ethereum Constantinople / St. Petersburg upgrade planned at block number 7,280,000 (predicted to occur Thursday, February 28, 2019). The exact date is subject to change.
However, those running their own nodes do have to take some steps to update to both Constantinople and St. Petersburg (in general it should be a single update to the new version of the software, see below).
Specifically, you have to update your Ethereum client (literally, you must update, you can’t run the old chain once the new chain launches; this is a “hard fork“).
Download the latest version of your Ethereum client (these are official links, feel free to verify for yourself using the official blog post below):
- Latest geth client (v1.8.23)
- Latest Parity client (v2.2.10-stable)
- Latest Harmony client (v2.3 Build 74)
- Latest Pantheon client (v0.9.1)
- Latest EthereumJS VM client (v2.6.0)
- Latest version of Ethereum Wallet/Mist (v0.11.1)
For a full and detailed explanation, please see Ethereum.org’s Ethereum Constantinople/St. Petersburg Upgrade Announcement.
THIS FORK PRODUCES NO FREE COINS: This upgrade is a planned update to the Ethereum network as defined in the Ethereum road map, it is not the type of hard fork that is meant to create a new coin, it was not born from a bug or an argument, it is simply an expected upgrade. It is likely there will be some scams trying to profit off low information coiners, so don’t go downloading “Ethereum fork wallets” and importing your keys into any wallet (unless you know what you are doing).
