Dear Ethereum Classic stakeholders,

The Ethereum Classic (ETC) network will be undergoing a planned hard-fork at block 9,573,000 mil or around January 12, 2020.

The Ethereum Classic test networks (Morden, Mordor, and Kotti) have successfully implemented the Agharta hard-fork.

To ensure a successful fork, we ask users to upgrade their clients to a fork-compatible version if they have not already done so. The specification proposed for the hard fork is being implemented in the following clients:

🛑 Classic Geth will reach END OF LIFE on January 12th, 2020. The Agharta hard-fork will be the last hard-fork supported by Classic Geth. If you are a Classic Geth user, then migrate to Besu, Multi-Geth, or Parity now.

🛑 Parity recently announced, “We have investigated reports of some Parity Ethereum nodes not syncing and believe there may be an attack underway. New releases v2.6.8-beta & v2.5.13-stable protect against this.”

The hard-fork can be watched at the hard-fork dashboard located here.

📡 If you are an exchange, wallet provider, infrastructure provider, developer, or anyone else operating Ethereum Classic nodes, then please sign-up to be coordinated with hard-fork alerts and related events here.

A hard fork is a change to the underlying Ethereum Classic protocol, creating new rules to improve the system. The protocol changes are activated at a specific block number. All Ethereum Classic clients need to upgrade, otherwise, they will be stuck on an incompatible chain following the old rules.

Agharta is a planned Ethereum Classic protocol upgrade. Agharta is occurring at block number 9,573,000 mil. Agharta implements Ethereum’s Constantinople upgrades to the Ethereum Classic network and has been adopted as an accepted Ethereum Classic Improvement specification which can be found at ECIP-1056.

Enable the following three hard fork features:

In the event that a critical bug is discovered, the following communication channels will be utilized:

A big thanks to the Ethereum Classic development community across all clients and platforms who came together to provide input, thoughts, and contributions for this upgrade.
