Finalized, rebranding the blog

If you've read my recent writings or listened to me speak about Ethereum and this grand upgrade that's in the works, you've perhaps noticed that I'm not only shying away from discussing "phases" (instead, referring to a series of independent upgrades), but that I've also been attempting to put the terms "eth1" and "eth2" to rest. I've spoken about these being terrible terms and wrote about it again in January's "The State of Eth2".

What we call "eth2" is a series of major upgrades to Ethereum's consensus-layer -- to ensure the protocol is secure, sustainable, and scalable -- while "eth2 clients" are implementations of this proof-of-stake consensus.

And, what we call "eth1" in this context is Ethereum's rich application-layer, and similarly, "eth1 clients" (after the upgrade to proof-of-stake) are the software that does the heavy lifting in this layer. Ethereum's application-layer is currently driven by a proof-of-work consensus algorithm but will soon be driven by the beacon chain -- the proof-of-stake consensus mechanism that is currently in production and secured by ~3.5M ETH.

Now to follow through on my campaign, I'm rebranding this blog series. From here on out, this series will be known as "Finalized: the Ethereum consensus-layer", where the name is an homage to the most critical function of the proof-of-stake consensus-layer -- finality.

Stakers: Upgrade your nodes

To stay connected, you must be Berlin compatible

The Ethereum PoW chain is undergoing a mainnet upgrade, called Berlin, on April 14, 2021. This is a backwards incompatible fork and thus requires updating your software to continue to follow mainnet. You can read more about this in the EF's Ethereum Berlin Upgrade Announcement.

As a beacon chain staker, you need an Ethereum PoW endpoint to successfully perform all of your various duties as a validator. This functionality serves as the uni-directional link between the components of the system to allow for new validator deposits.

It follows that, to successfully maintain this link, stakers must upgrade their Ethereum PoW nodes! If you run the Pyrmont testnet, you must upgrade your Goerli nodes before March 17, 2021, and if you validate on mainnet, you must upgrade your mainnet PoW nodes before April 14, 2021.

Also, a good time to upgrade your beacon node

In addition to upgrading your PoW nodes, I highly recommend upgrading your beacon nodes too. There have been many juicy optimizations recently to all mainnet clients. To ensure your validators run with optimal performance (and profitability), pull down the latest release and give it a whirl.
