The Ethereum community has phased out the terms "Eth1" and "Eth2" since 2022, adopting "execution layer" and "consensus layer" instead to describe the upcoming network upgrade. While this terminology shift hasn't sparked significant discussion in domestic crypto circles, it signals Ethereum's core team finalizing preparations for its most ambitious overhaul yet.
Why This Upgrade Matters
Two pivotal factors underscore the importance of this upgrade:
- Technical Milestone: Following EIP-1559, this represents Ethereum's next major evolution—merging the existing chain with the Beacon Chain while phasing out PoW miners via the difficulty bomb. This transition may disrupt GPU manufacturers, potentially alleviating global chip shortages. The difficulty bomb refers to a sudden spike in mining difficulty at specific block heights, preventing PoW mining post-transition.
- Ecosystem Influence: As the leading smart contract platform and second-largest cryptocurrency, Ethereum's upgrade will reshape the crypto landscape.
Key questions emerge:
- What necessitates this urgent upgrade?
- When will it occur?
- How will it impact the broader industry?

1. The Urgency Behind Ethereum's Upgrade
Examining why Ethereum "must upgrade now" reveals four critical pain points:
A. Exorbitant Gas Fees
Despite competition from Solana, Avalanche, and other high-performance chains, Ethereum maintains prohibitively high transaction costs. Imagine if Alipay charged $1,000 per transaction—it would never have disrupted traditional finance. On Ethereum, users bid for limited block space, creating a "pay-to-play" environment where fees sometimes exceed transaction values (e.g., purchasing low-cost NFTs).
B. Energy Inefficiency
PoW consensus consumes vast electricity—a growing liability amid global sustainability efforts. As Ethereum scales, historical data accumulation also raises node operation costs, hindering decentralization.
C. Performance Bottlenecks
Slow execution speeds limit complex dApp functionality, constraining developer innovation.
D. GPU Market Strain
PoW mining has caused GPU shortages, inflating prices 3-5x above MSRP on platforms like eBay. This impacts gamers, multimedia professionals, and hardware enthusiasts.
2. Four Industry-Wide Impacts
Impact #1: ETH Scarcity
The merge activates EIP-1559's burn mechanism alongside PoS, transitioning ETH to deflationary. Since August 2021, 1.797M ETH were burned vs. 2.524M minted—a net reduction of 712K ETH. Post-upgrade, eliminated miner rewards will accelerate scarcity.
Impact #2: High-Performance Chains
Contrary to assumptions, PoS won't boost throughput. Vitalik Buterin notes PoS blocks require thousands of signatures per validation, possibly lengthening confirmation times beyond PoW's ~13-second average. This preserves opportunities for competing L1 chains.
Impact #3: ETHash-Based Projects
Displaced PoW miners may migrate to other ETHash-algorithm networks, potentially boosting projects like Ethereum Classic.
Impact #4: Market Sentiment
Historical precedent exists: The August 2021 EIP-1559 upgrade catalyzed a market rebound, with BTC later hitting $69K. A successful merge could similarly buoy crypto valuations.

FAQs
Q1: When will the Ethereum merge occur?
A: Currently slated for June 2022, following the difficulty bomb delay from October 2021.
Q2: Will PoS reduce gas fees?
A: Not directly. Layer-2 solutions like rollups remain essential for fee reduction.
Q3: How might the upgrade affect GPU prices?
A: Post-merge, reduced mining demand could stabilize GPU costs over time.
Q4: What happens to staked ETH after the merge?
A: Staked ETH becomes withdrawable, though phased releases may prevent market flooding.
Q5: Could the merge be delayed again?
A: Possible, but core developers emphasize 2022 as the target year.
In summary, Ethereum's upgrade will amplify its dual roles as sound money and a robust dApp platform—setting the stage for Web3's next phase.
