🎉🎉 Lighthouse produced its first #Eth1 & #Eth2 merge transaction 🎉🎉

This is an ETH tx using *only* proof-of-stake validators. A step towards a 99.98% drop in Ethereum energy consumption 🌏🌲🌄

Credits to @gballet, @mkalinin2 & @Teku_ConsenSys!

Important qualifications 👇

This is exciting, but it doesn't mean that we're ready for production. This is a prototype and there's still a lot of questions to answer and work to do.

Primarily, you should take this is a signal that Eth1 and Eth2 developers are actively working together on the merge. 🧑‍🤝‍🧑

They got a shout-out earlier, but don't forget that Teku also achieved the same thing in the initial prototype.

This prototype uses a fork of Geth called "Catalyst". This is maintained by @gballet who has been great help throughout the process.

Lighthouse and Geth talk via an RPC; Lighthouse does the proof-of-stake work and Geth manages the account state.

Moving Ethereum to proof-of-stake is part of the Eth2 effort. Learn more about Eth2 here:

At @sigp_io, we're dedicated to helping Ethereum transition to proof-of-stake.

The energy consumption reductions are imperative for success in a world that's becoming more and more climate-conscious.

We owe it to Ethereum and we owe it to future generations.
