The Merge Nearing Buterin talks Surge

Ethereum's chief scientist says PoS will complete network halfway
The Merge is imminent. Rising hopes for a new, more powerful Ethereum have boosted DeFi in the recent week.

Ethereum will be halfway there after The Merge. The network will begin The Surge next.

Important

Vitalik Buterin, Ethereum's principal scientist and co-founder, presented this message July 21 in Paris.

Buterin claimed Ethereum's shift from Proof-of-Work to Proof-of-Stake will be "difficult" He revealed many future information.

Buterin: "The Ethereum protocol is undergoing a long and complicated transformation" After The Merge, Ethereum will have fulfilled 55% of its roadmap. The Merge will reduce Ether issuance by 90% and boost network energy efficiency by 99%.

Buterin claimed Proof of Stake will decrease fresh ETH issuance from 5M to 166 times annual deposits. Buterin says yearly issuance will be 166,000 if 1M ETH is pledged, and 1.66M if 100M ETH is staked.

Wisdom

Staking Rewards reports 13M Ether is staked on Eth2 Beacon Chain.
PoS will bring Data Availability Sampling (DAS), allowing the blockchain to run without a single node processing the full chain. Buterin calls the change "absolutely obvious sense" from a distributed systems perspective.

Nobody would construct a BitTorrent version where everyone downloads every movie. He stated that's how blockchains work today.
Buterin said DAS combines blockchain security with peer-to-peer network data delivery.

Buterin said the procedure is undergoing disruptive improvements that would result in "long-term rewards" but "short-term misery." After the modifications, he expects Ethereum will "calm down."
Buterin said decentralization is harder when protocols change quickly and the system is complex. "Decentralization is easier with simpler, slower-changing protocols.

Ethereum's Layer 1 may "optimize for safety," while Layer 2 will permit "fast iteration and action," he claimed.

The Surge will bring sharding and more data capacity to make rollups "up to 10 times cheaper" after The Merge. L2beat reports that top L2s Arbitrum and Optimism have received more than $3B in rollups. They bundle transactions on a quick, cheap second-layer chain before sending them to Ethereum's mainnet for batch verification.

Post-Merge Ethereum

Buterin predicts that Ethereum will be able to execute 100,000 transactions per second after the surge, including rollups and sharding.
The Verge will introduce verkle trees and stateless clients to make Ethereum lighter. Buterin said following The Verge, "you can verify Ethereum blocks and be a validator without hundreds of megabytes on your disc, which is excellent for decentralization."
The Purge will remove old network history to simplify Ethereum and reduce validators' hard drive space needs.  After the upgrade, Buterin expects nodes won't need to store blockchain history.

Validators

The Splurge will increase the network's operation and efficiency, according to Buterin.

Looking beyond the current plan, Buterin intends to make it easier for home stakers and smaller validator pools, as well as enabling users to run a full node on light hardware.

I still want mobile phone betting. Upgrades coming Buterin suggests optimizing for quantum resistance once quantum computing is a reality, increasing transaction space to allow zero-knowledge-based EVMs, and being open to future cryptographic upgrades that could increase efficiency or simplicity.
