Eth2’s Altair upgrade now shuts down smoothly with the 98.7% node upgrade

The Ethereum 2.0 Altair Beacon Chain update got off to a successful start, with 98.7% of the nodes already upgraded.

October 27, Ethereum 2.0 developer Preston Vanloon Tweeted that Altair upgrade “successfully activated”

Altair is the first upgrade of the beacon chain since it went online in December 2020 and is likely to be completed before the integration with Ethereum Mainnet and the proof-of-stake change.

The upgrade brings light-client support to the original consent, clears Beacon State Incentive accounting, resolves some issues with validator incentives, and increases punitive parameters (penalties for offline validators) in accordance with EIP-2982.

Paul Hauner is the chief developer and reviewer of Lighthouse’s Altair Code, an Ethereum 2.0 implementation. Hauner told the Quintelegraph:

“Altair introduced two early changes. First, it added support for light clients, which are low-resource nodes that follow chains with fewer features and slightly weaker security assumptions. Think of a light node on your phone or your browser. Second, It increased the penalties for staying offline and slashing. These penalties were set lower than Genesis so we didn’t penalize users who were just learning the ropes. Combining these penalties would increase. In addition to these two initial changes, there were a handful of skills and neatness. “

The Altair upgrade was a tough thorn, meaning that any of the 250,000 or more verifiers who didn’t upgrade are now offline, and their ETH share is slowly declining at a rate of about 10% per year.

To be compatible with Altair upgrades, Beacon Node operators need to update their client version, a process that takes about 10 minutes.

Although participation dropped to 93.3% in the first period after the upgrade, it has grown rapidly to about 95% and has since risen to about 98.7%, with only one percent going.

“It looks like we have virtually all verifiers online and now running Altair. It’s hard to say about these privacy-protection systems, but I would say we don’t have more than 1-2% offline yet,” Hauner said.

According to Beacon Chain, it has about 247,400 active verifiers and 3,000 inactive verifiers.

Ethereum 2.0 developer Jeff Coleman Tweets, “If they don’t fix it, they will cross a threshold and be expelled.”

“I believe there will be a complete emission if they go below 16 ETH, which will still take quite a long time since the network is finalized,” Coleman said.

“The protocol does not see any difference between a validator who has not upgraded and is temporarily offline due to a power or network problem. Those who have not updated just need to update and then restart their nodes. Caught up with the Altair chain, ”Hauner explained.

Ethereum devs will breathe a sigh of relief because a successful upgrade means the goal is to fully assemble the steam and be ready to “shut down proof of work forever” by February 2022.

Developer Ben Easington outlined the significance of the upgrade in a blog post earlier this month:

“This is our only and only real-life practice to upgrade the beacon chain before it is assembled. If it goes badly (probably because many stackers haven’t upgraded their clients in time), it will definitely delay the merger date. “

“Proof of the steak upgrade, known as The Merge, will be the biggest upgrade in Ethereum’s history.”

“The Altair upgrade will give us a valuable experience so that the merge will go smoothly when it is ready for deployment in 2022,” Agenton said.

The Beacon Chain is the first phase of Ethereum’s new proof-of-stack blockchain, which will integrate with the current mainnet as part of the Ethereum 2.0 implementation.

PoS is 99% more energy-efficient than PoW, a method used by Bitcoin (BTC) miners and relies on stackers and legitimizers instead of miners.

The final upgrade of Ethereum 2.0 is scheduled for early 2022.
