One year after The Merge, the most significant upgrade in Ethereum’s history, the blockchain has undergone a radical transformation—both environmentally and economically. Transitioning from a proof-of-work (PoW) to a proof-of-stake (PoS) consensus mechanism was never just a technical shift; it was a strategic repositioning of Ethereum’s long-term sustainability, security, and economic model. But has it delivered on its promises?
The answer, based on data and network behavior, is largely yes—though with nuances that matter.
A Greener Ethereum: Environmental Impact After The Merge
One of the primary goals of The Merge was to drastically reduce Ethereum’s energy consumption. Prior to September 2022, Ethereum relied on energy-intensive mining operations, similar to Bitcoin, where computational power determined network security. This model came at a high environmental cost.
After the transition to PoS, that model was replaced with one where validators "stake" ETH to secure the network—eliminating the need for power-hungry mining rigs.

According to data from the Cambridge Bitcoin Electricity Consumption Index (CBECI), Ethereum’s annual electricity usage dropped by 99.9%, now sitting at just 0.00731 TWh. To put this in perspective:
- Bitcoin consumes approximately 120.31 TWh per year.
- Ethereum now uses less power than major tech companies like PayPal and Netflix.
The environmental benefits extend beyond electricity. The Crypto Carbon Ratings Institute (CCRI) reports that Ethereum’s annual carbon emissions have fallen by over 99%, now estimated at only 2,659 metric tons of CO₂—comparable to the footprint of a small town.
This shift not only aligns Ethereum with global sustainability goals but also improves its appeal to institutional investors wary of funding carbon-heavy technologies.
Why This Matters for Adoption
As ESG (Environmental, Social, and Governance) criteria become central to investment decisions, Ethereum’s green transformation strengthens its position as a viable infrastructure for decentralized finance (DeFi), NFTs, and Web3 applications.
Developers, enterprises, and users can now build and transact on Ethereum without the ethical dilemma of contributing to excessive energy use.
Ethereum Turns Deflationary: A New Economic Era
Beyond sustainability, The Merge introduced a fundamental change in Ethereum’s monetary policy: deflationary pressure.
Before the upgrade, Ethereum had an inflationary supply model. Miners were rewarded with newly minted ETH for validating blocks, leading to a daily issuance of around 13,000 ETH. This contributed to a projected annual inflation rate of 3.16% if no changes were made.
Post-Merge, the issuance model shifted dramatically:
- Block rewards are now given to stakers instead of miners.
- The EIP-1559 fee-burning mechanism continues to destroy a portion of transaction fees.
- With fewer ETH issued and some permanently removed from circulation, the network has entered a net deflationary state.
As reported by ultrason.money, over 300,000 ETH have been removed from circulation since The Merge—a net supply reduction of approximately 0.248% per year.
👉 See how deflationary mechanics are reshaping digital asset value.
Without the transition, Ethereum’s total supply would have grown by more than 3.8 million ETH by now. Instead, it’s on track to stabilize.
Long-Term Supply Outlook
Projections suggest that Ethereum’s supply will hover around 120 million ETH by August 2024. After that point, continued fee burning could lead to a steady decline in circulating supply—assuming consistent transaction volume.
This deflationary trend could create upward price pressure over time, especially if demand grows alongside institutional adoption and ecosystem expansion.
The Rise of Staking: Security and Participation Surge
The success of PoS hinges on participation. The more ETH staked, the more secure and decentralized the network becomes.
While The Merge laid the foundation, full withdrawal functionality only became possible after the Shapella upgrade in April 2023. This allowed validators to unstake their ETH freely—boosting confidence and encouraging broader participation.
Since then, staking activity has surged:
- Total staked ETH reached a new high of 29.06 million, according to Glassnode.
- That represents a 58% increase post-Shapella.
Higher staking levels mean greater network security. With more economic value at stake, malicious actors face higher costs to attack the system.
Moreover, retail and institutional investors alike are increasingly viewing staking as a way to earn yield while supporting network integrity—further reinforcing Ethereum’s economic flywheel.
Lingering Concerns: Centralization Risks and Market Response
Despite the progress, challenges remain.
Centralization in Block Production
Matt Cutler, CEO and co-founder of blockchain infrastructure firm Blocknative, raised concerns about centralization in block construction:
“Over the past 14 days, about 75% of Ethereum blocks were built by just three block builders—two of which are widely seen as vertically integrated searcher-builder entities. That doesn’t look like the level of decentralization the ecosystem hopes for.”
While validator distribution remains relatively decentralized (with over 500,000 active validators), the concentration of block-building power introduces potential risks. If a small group controls transaction ordering, it could enable front-running or censorship under certain conditions.
Developers are aware of this issue and are working on solutions like Proposer-Builder Separation (PBS) and distributed builder networks to enhance fairness and resilience.
Price Performance: Innovation vs. Market Sentiment
Another point of debate is Ethereum’s price performance since The Merge.
According to CoinMarketCap, ETH has appreciated by only about 11% in the year following the upgrade. This modest gain contrasts with the magnitude of the technical achievement.
It underscores a key truth in crypto markets: price is often driven more by macro sentiment and speculation than by fundamentals alone.
Bullish cycles are influenced by factors like regulatory clarity, macroeconomic conditions (e.g., interest rates), and investor risk appetite—not just protocol improvements.
So while The Merge strengthened Ethereum’s foundation, its market value still moves in sync with broader crypto trends.
Frequently Asked Questions (FAQ)
Q: Did The Merge make Ethereum completely carbon neutral?
A: While Ethereum is not officially carbon neutral, its carbon footprint has dropped by over 99%. Ongoing efforts aim to offset remaining emissions through green initiatives and carbon credits.
Q: Can anyone participate in staking now?
A: Yes. After the Shapella upgrade, users can stake as little as 32 ETH independently or use liquid staking services (like Lido or Rocket Pool) to stake smaller amounts with flexibility.
Q: Is Ethereum deflationary all the time?
A: Not continuously. Deflation depends on transaction activity and fee levels. High network usage leads to more fee burning, increasing deflationary pressure. During low activity, inflation may briefly return due to staking rewards.
Q: How does staking affect ETH’s price?
A: Staking removes ETH from circulation temporarily, reducing selling pressure. As more ETH gets locked up, available supply decreases—potentially supporting price growth if demand remains strong.
Q: What’s next for Ethereum after The Merge?
A: Future upgrades focus on scalability and efficiency—such as Danksharding, rollups integration, and further enhancements to reduce fees and increase throughput.

Final Thoughts: A Foundation for the Future
One year after The Merge, Ethereum has undeniably achieved its core objectives:
- Drastically reduced energy consumption
- Improved environmental sustainability
- Introduced deflationary monetary policy
- Strengthened network security through increased staking
While concerns around centralization and short-term price performance persist, they reflect growing pains rather than systemic failures. Ethereum remains at the forefront of blockchain innovation—building a more sustainable, secure, and economically sound platform for the future of digital assets.
The Merge wasn’t the end goal—it was the beginning of Ethereum’s next chapter.
