One year after The Merge, Ethereum’s historic transition from proof-of-work (PoW) to proof-of-stake (PoS), the blockchain has made significant strides in sustainability and economic design. While the shift was primarily aimed at slashing energy consumption and introducing deflationary mechanics, the long-term implications for scalability, decentralization, and market value remain nuanced. This article explores whether Ethereum has fulfilled its core objectives—and what lies ahead.
A Greener Blockchain: Environmental Impact After The Merge
The most immediate and measurable success of The Merge has been its dramatic reduction in energy consumption.
Prior to September 2022, Ethereum operated on a PoW consensus mechanism, similar to Bitcoin, where miners competed using high-powered hardware to validate transactions. This process consumed vast amounts of electricity—raising environmental concerns as global awareness of climate change intensified.
Post-Merge, Ethereum now relies entirely on staking, where validators lock up ETH to participate in block production. This change eliminated the need for energy-intensive mining rigs.
According to the Cambridge Bitcoin Electricity Consumption Index (CBECI), Ethereum's annual electricity usage dropped by over 99.9%, from an estimated 78.85 TWh pre-Merge to just 0.00731 TWh today. To put this into perspective:
- Ethereum now uses less power than PayPal or Netflix.
- Its annual carbon footprint has fallen by over 99%, down to approximately 2,659 tons of CO₂, per data from the Crypto Carbon Ratings Institute.

This transformation positions Ethereum as one of the most environmentally responsible layer-1 blockchains, potentially attracting institutional investors wary of ESG (Environmental, Social, and Governance) risks associated with PoW assets like Bitcoin.
Ethereum Turns Deflationary: Supply Dynamics Shift
Beyond sustainability, The Merge introduced a critical economic upgrade: deflationary pressure on ETH supply.
Before the transition, Ethereum had an inflationary model. Miners were rewarded with newly minted ETH for securing the network—approximately 13,000 ETH per day were issued. This led to a projected annual inflation rate of around 3.16%, increasing the total supply over time.
After switching to PoS, two key mechanisms reshaped supply dynamics:
- Reduced issuance: Staking rewards are significantly lower than mining rewards.
- EIP-1559 fee-burning mechanism: A portion of transaction fees (the base fee) is permanently burned with every transaction.
As a result, Ethereum has entered a net deflationary state. According to ultrason.money, more than 300,000 ETH have been removed from circulation since The Merge—a net contraction of supply at an annualized rate of 0.248%.
Without the transition, Ethereum’s total supply would have grown by over 3.8 million ETH by now. Instead, it’s on track to stabilize.
Long-term projections suggest that ETH supply will hover near 120 million by August 2024 before beginning a gradual decline. This shift could enhance scarcity and support upward price pressure—if demand keeps pace.
Why Deflation Matters
A shrinking supply can create bullish fundamentals, especially if adoption grows. Scarce assets with rising utility often appreciate in value over time—assuming market sentiment aligns with these fundamentals.
However, so far, ETH’s price performance post-Merge tells a more complex story.
Price Performance vs. Technological Progress
Despite major technical achievements, Ethereum’s market value has seen only modest gains since The Merge.
According to CoinMarketCap data, ETH’s price has risen approximately 11% in the 12 months following the upgrade. While this reflects some positive momentum, it pales in comparison to the hype surrounding the event.
This disconnect highlights a crucial reality: crypto markets are driven more by sentiment and macroeconomic factors than by technological upgrades alone.
Even transformative changes like eliminating energy waste or turning deflationary don’t guarantee immediate price rallies—especially in bearish or uncertain macro environments.
Yet, long-term investors may view this as a sign of resilience rather than failure. The foundation is being strengthened for future growth phases.
Staking Adoption Reaches New Heights
One of the clearest signs of confidence in Ethereum’s new model is the surge in staking activity.
Before April 2023’s Shapella upgrade, staked ETH was locked and illiquid—discouraging participation. Once Shapella enabled withdrawals, users gained full control over their assets, boosting trust and engagement.
Since then, staking has exploded in popularity:
- Total staked ETH reached a record 29.06 million, according to Glassnode.
- That represents a 58% increase post-Shapella.
- Over 23% of all ETH in circulation is now staked.
Higher staking participation improves network security—more validators mean greater resistance to attacks. It also signals growing belief in Ethereum’s long-term viability.

Lingering Concerns: Decentralization at Risk?
Despite progress, challenges remain—particularly around decentralization, a core principle of blockchain technology.
Matt Cutler, CEO and co-founder of blockchain infrastructure provider Blocknative, raised alarms about centralization trends in block production:
“Over the past 14 days, roughly 75% of Ethereum blocks were built by just three entities—two of which are widely seen as vertically integrated searcher-builder operations.”
This concentration undermines the ideal of a distributed network. If a small number of players dominate block construction (even if thousands validate), it opens doors to censorship risks and MEV (Maximal Extractable Value) manipulation.
While staking itself is highly decentralized—with thousands of individual validators—the backend infrastructure for block building is increasingly centralized among a few sophisticated players.
Ethereum developers are actively working on solutions like Proposer-Builder Separation (PBS) and distributed builders to mitigate these risks. But for now, this remains a valid concern.
Frequently Asked Questions (FAQ)
Q: What was the main goal of The Merge?
A: The primary goals were to drastically reduce Ethereum’s energy consumption by moving from proof-of-work to proof-of-stake and to lay the groundwork for improved scalability and security.
Q: Did Ethereum become more energy-efficient after The Merge?
A: Yes—energy usage dropped by over 99.9%, making Ethereum one of the most eco-friendly major blockchains today.
Q: Is Ethereum truly deflationary now?
A: Yes, due to reduced issuance and ongoing ETH burns via EIP-1559, Ethereum has experienced net deflation since The Merge, though the rate is currently slow.
Q: Has ETH price gone up significantly since The Merge?
A: Not dramatically—ETH gained about 11% in the year following the upgrade, indicating that market sentiment and macro factors still outweigh technical improvements in the short term.
Q: How does staking work after The Merge?
A: Validators lock up 32 ETH to run a node and earn rewards for proposing and attesting blocks. Smaller holders can use liquid staking services like Lido or Rocket Pool.
Q: Are there risks to Ethereum’s decentralization post-Merge?
A: Yes—while validation is decentralized, block-building concentration among a few entities poses potential centralization risks that developers are actively addressing.
Final Thoughts: A Foundation Built for the Future
One year after The Merge, Ethereum has undeniably achieved its core technical objectives: becoming vastly more sustainable and introducing deflationary supply mechanics.
But true success isn’t measured solely by engineering milestones—it’s also about adoption, economic resilience, and staying true to decentralization principles.
While price gains have been muted and structural concerns linger, the long-term trajectory looks promising. With continued upgrades like Proto-Danksharding and full danksharding on the horizon, Ethereum is laying the groundwork for mass adoption.
For those watching closely, now might be the time to deepen understanding—and consider positioning for what comes next.
