Ethereum Cat Herders

Welcome to the Ethereum cat Herders’ website, the go-to place to get the latest news on upcoming Network Upgrades (Hard Forks), EIP’s, announcements and overall core developer and community coordination efforts.


The Ethereum Cat Herders are a group of independent contributors serving the Ethereum community. We are here to support Ethereum developer teams by coordinating Hard Forks, monitoring EIPs, creating PM processes and retroactive reports, relaying information between teams, taking notes during All Core Devs calls and much more.

Our aim is to bring the minumum amount of order that chaos needs to move Ethereum forward.

Upcoming Network Upgrade

On 16 January 2019, a decision was taken to postpone the upgrade of the Ethereum Network, the upgrade named “Constantinople”, scheduled to complete on 17 December 2019.

The next network upgrade “Constantinople 2” is targeted at 27 February 2019, block number 7.280.000.

All major clients have already implemented these changes. Progress can be tracked here.
