The Merge marks one of the most significant upgrades in Ethereum’s history — a long-anticipated shift from Proof-of-Work (PoW) to Proof-of-Stake (PoS). After nearly eight years of development and testing, Ethereum has successfully transitioned to a more efficient, secure, and environmentally sustainable consensus mechanism. This transformation brings profound changes to Ethereum’s inflation rate, gas fee dynamics, and energy consumption.
In this article, we’ll explore how The Merge reshapes the economic and technical foundations of the Ethereum network, clarify common misconceptions, and highlight what users can realistically expect in the post-Merge era.
Understanding the Shift: From PoW to PoS
Before The Merge, Ethereum operated on a Proof-of-Work (PoW) consensus model, similar to Bitcoin. In PoW, miners compete to solve complex mathematical puzzles using high-powered computing hardware. The first miner to solve the puzzle gets the right to add a new block to the blockchain and is rewarded with newly minted ETH — approximately 16,000 ETH per day.
This process was not only energy-intensive but also contributed to continuous ETH inflation due to high issuance rates.
With The Merge, Ethereum transitioned to Proof-of-Stake (PoS), where block validation is handled by validators who stake their own ETH as collateral. Instead of miners, these validators are randomly selected to propose and attest to new blocks. As a result, daily ETH issuance dropped by about 90%, now averaging around 1,600 ETH per day.

This dramatic reduction in issuance is a cornerstone of Ethereum’s new economic model — setting the stage for potential deflationary behavior.
Ethereum’s Path to Deflation: EIP-1559 and Burn Mechanics
While reduced issuance helps control inflation, it doesn’t automatically make ETH deflationary. That’s where EIP-1559 comes into play — a critical upgrade implemented in August 2021 that fundamentally changed how transaction fees work.
Under EIP-1559:
- A portion of every gas fee is permanently burned (destroyed).
- Only the "priority fee" (or tip) goes to validators.
- Base fees adjust dynamically based on network congestion.
Since its launch, over 2.6 million ETH have been burned through this mechanism — averaging around 6,400 ETH per day.
Now, combine this with The Merge’s reduced issuance:
- Pre-Merge: 16,000 new ETH issued daily vs. ~6,400 burned = high net inflation
- Post-Merge: ~1,600 new ETH issued daily vs. ~6,400 burned = net deflation
At average network usage (around 16 gwei gas price), more ETH is burned than created. This means Ethereum has become a deflationary asset under normal conditions — a powerful shift for long-term value accrual.
Gas Fees: Why They Won’t Drop After The Merge
A common misconception is that The Merge would reduce gas fees. Unfortunately, it does not.
Gas prices are determined by supply and demand:
- Supply: Block space (how many transactions fit in a block)
- Demand: Number of pending transactions on the network
Think of each Ethereum block as a bus with fixed seating capacity. Every transaction is a passenger trying to get on. If too many people want to board, those willing to pay extra (higher gas fees) get priority.

The Merge did not increase block size or frequency — blocks still arrive roughly every 12 seconds and hold about the same amount of data. Therefore, during periods of high demand (e.g., NFT mints or DeFi surges), gas prices remain volatile.
Interestingly, low gas fees are often misinterpreted as network failure ("NFTs are dead"), when in reality they simply reflect low network activity — fewer people trying to board the bus.
So when will gas fees drop sustainably?
The Road to Scalability: Layer 2s and Danksharding
True scalability — and lower fees — won’t come from The Merge alone. It requires expanding Ethereum’s capacity to process more transactions without sacrificing decentralization or security.
Originally, Ethereum planned to use sharding — splitting the blockchain into smaller chains (shards) to distribute load. However, the roadmap has evolved. Now, the focus is on Layer 2 scaling solutions, particularly Rollups, combined with an advanced sharding design called Danksharding.
Here’s how it works:
- Most transactions occur off-chain via Rollups (like Optimism or Arbitrum).
- These Rollups batch thousands of transactions and submit compressed data to Ethereum’s main chain.
- Danksharding allows even more data to be processed efficiently through “data blobs,” reducing main chain congestion.
This combination could scale Ethereum to handle up to 100,000 transactions per second — a massive leap from today’s ~24 TPS.
This next phase is expected to roll out starting in 2025 and represents the next major milestone after The Merge.
Environmental Impact: 99% Reduction in Energy Use
One of the most immediate and measurable impacts of The Merge is its environmental benefit.
Under PoW, Ethereum consumed an estimated 78 terawatt-hours (TWh) per year — comparable to the energy usage of entire countries like Chile or Austria.
With PoS:
- No more energy-hungry mining rigs
- Validators run lightweight software on consumer-grade hardware
- Total energy consumption drops by over 99%
This shift transforms Ethereum from one of the most criticized blockchains in terms of carbon footprint into one of the greenest major networks in crypto.
Frequently Asked Questions (FAQ)
Q: Does The Merge make Ethereum deflationary?
Yes — under normal network conditions. With daily issuance reduced to ~1,600 ETH and average burn rates at ~6,400 ETH (thanks to EIP-1559), more ETH is destroyed than created, resulting in deflation.
Q: Why haven’t my gas fees gone down after The Merge?
Because The Merge didn’t increase block size or reduce transaction demand. Gas prices depend on congestion, not consensus mechanism. Scalability solutions like Layer 2s will address this long-term.
Q: Is staking safer now than before?
Yes. In PoS, validators must stake 32 ETH and follow protocol rules. Misbehavior leads to penalties (“slashing”), making attacks costly and unlikely.
Q: Can I still mine Ethereum after The Merge?
No. Mining no longer exists on Ethereum. All new blocks are validated by stakers. Former miners have either upgraded to become validators or moved to other PoW chains.
Q: What comes after The Merge?
The next major upgrades include Proto-Danksharding and full Danksharding, aimed at boosting scalability through Layer 2 integration and data availability improvements — expected from 2025 onward.
Q: How does reduced issuance affect ETH price?
Lower supply growth increases scarcity, especially when combined with burning. Historically, assets with controlled or negative issuance tend to show stronger long-term value retention.

Conclusion
The Merge is not just a technical upgrade — it’s a paradigm shift for Ethereum. By slashing energy consumption by 99%, reducing inflation, and laying the foundation for future scalability, it positions Ethereum as a more sustainable, secure, and economically sound platform for decentralized applications.
While gas fees remain unchanged for now, the roadmap ahead promises transformative improvements through Layer 2 innovation and data layer advancements.
As Ethereum evolves, so too does its role in shaping the future of digital ownership, finance, and trustless systems.
