As 2022 came to a close, one event stood out as a defining moment in the cryptocurrency landscape—the Ethereum Proof-of-Stake (PoS) merge. This pivotal upgrade marked the final phase of Ethereum 2.0’s long-anticipated evolution, transitioning the network from energy-intensive Proof-of-Work (PoW) mining to a more sustainable and efficient PoS consensus mechanism. Beyond this landmark shift, Ethereum’s ecosystem witnessed significant developments throughout the year, including economic fluctuations, reduced on-chain activity, and the continued rise of Layer 2 scaling solutions.
This article explores how Ethereum navigated a turbulent macroeconomic climate, transformed its monetary policy, and set the stage for future innovation—all while maintaining its position as a foundational pillar of decentralized applications.
Ethereum's Price Performance Amid Macroeconomic Headwinds
The global financial environment significantly influenced crypto markets in 2022, with the U.S. Federal Reserve's aggressive monetary tightening playing a central role. As inflation pressures mounted, then-Fed Chair Jerome Powell signaled potential rate hikes as early as January 2022, sparking widespread risk-off sentiment across digital assets.
Ethereum (ETH), like other cryptocurrencies, was not immune. On January 4, ETH reached a peak of $3,900.01 before plummeting nearly 25% by January 10, dropping to around $2,933. The downward trend intensified through May and June, with ETH hitting a low of approximately $881—representing a decline of over 75% from its previous highs.
By the second half of the year, ETH stabilized within a range of $1,200 to $1,800—levels reminiscent of early 2021, well below its all-time highs. Notably, ETH/BTC trading pairs fell from 0.072 to 0.054, indicating that Ethereum underperformed relative to Bitcoin during this bear market.

While 2023’s trajectory remains uncertain, it is clear that Ethereum’s price dynamics are increasingly intertwined with macroeconomic indicators, particularly U.S. monetary policy. Investors must remain vigilant and adapt risk management practices accordingly.
Declining On-Chain Activity Reflects Market Cool-Down
Beyond price movements, on-chain metrics reveal a broader contraction in Ethereum’s ecosystem activity in 2022:
- Daily transactions dropped from an average of 1.17 million at the start of the year to about 1.04 million by year-end—a decline of over 10%. Temporary spikes in July and December corresponded with periods of market panic or FOMO-driven activity.
- Gas fees, after declining mid-year, rebounded toward year-end due to increased smart contract deployments, signaling ongoing developer interest despite market conditions.
- Active addresses fell from 518,000 daily at the beginning of the year to 453,000 by December—a 12% decrease—reflecting reduced user engagement.
- Network revenue plummeted from over $25 million per day in early 2022 to under $4 million by mid-year, a drop exceeding 84%, driven by lower transaction volumes and reduced DeFi activity.
Additionally:
- Dapp count: As of late 2022, Ethereum hosted 3,598 decentralized applications (DApps), accounting for 27.8% of all DApps across blockchains.
- DeFi TVL: Total value locked (TVL) on Ethereum dropped from ~$90 billion in March to $23.4 billion by December—a staggering 74% decline. While still leading with 59.24% of total cross-chain DeFi TVL, this reflects a faster contraction compared to some competing chains.
These trends underscore a cooling in speculative activity but also highlight Ethereum’s enduring strength as a foundational platform for long-term builders.
From Inflation to Deflation: The Impact of the PoS Merge
The most transformative development of 2022 was the successful completion of the Ethereum PoS merge, executed in two phases:
- Bellatrix upgrade (September 6, HKT) – activated the consensus layer.
- Paris upgrade (September 15, HKT) – finalized the transition when the network reached terminal total difficulty (TTD).
With the merge, Ethereum eliminated energy-intensive mining, reducing annual ETH issuance from ~4.3% to just ~0.43%—a reduction of over 90%. This drastic cut turned Ethereum into a net-deflationary asset under certain conditions.
Post-merge data revealed that by December 21, only 2,212 new ETH were minted net—a stark contrast to pre-merge inflation rates. This deflationary pressure was further amplified by EIP-1559’s base fee burning mechanism.

Layer 2 Scaling: Innovation Amid Market Downturn
Despite broader market stagnation, Layer 2 (L2) solutions continued to evolve and gain traction. With Ethereum mainnet still facing scalability challenges post-merge, L2 networks such as Arbitrum, Optimism, zkSync, and StarkNet played a crucial role in maintaining ecosystem vitality.
As of late 2022:
- Total L2 TVL stood at $4.24 billion.
- Arbitrum led with $2.3 billion (54.2% share).
- Optimism followed with $1.14 billion (26.9%).
- dYdX ranked third with $391 million.
Notable projects launched on L2s include The Beacon, a blockchain game released on Arbitrum by TreasureDAO, which attracted over 18,000 players and sold more than 17,000 NFTs within a week.
Moreover, cross-layer bridges improved liquidity and usability between L2s and the Ethereum mainnet. Given their advantages in speed and cost-efficiency, L2s are expected to remain critical until full Ethereum 2.0 deployment.

Looking ahead, once Ethereum implements sharding and full scalability via 2.0, L2s will operate across multiple shards—enabling unprecedented throughput and synergy between layers.
What’s Next? The Road Beyond the Merge
The upcoming Shanghai upgrade, expected in Q1 2023, will unlock critical functionalities:
- EIP-4895: Enable withdrawals of staked ETH and rewards.
- EIP-3655 / EIP-3860: Enhance EVM efficiency and security.
- Potential gas optimizations via EIPs targeting contract execution costs.
These upgrades will improve staker flexibility and encourage wider participation in network validation.
However, major enhancements like sharding may still be years away due to the need for extreme caution—any flaw could jeopardize billions in value secured on Ethereum.
Frequently Asked Questions (FAQ)
Q: Did Ethereum become deflationary after the PoS merge?
A: Yes. With drastically reduced issuance and ongoing fee burning via EIP-1559, Ethereum entered a net-deflationary state under normal usage conditions post-merge.
Q: How did the PoS merge affect ETH supply?
A: Annual ETH issuance dropped by over 90%, from ~4.3% to ~0.43%. This reduction significantly slowed inflation and enabled deflation when transaction volume is high enough to burn more than is issued.
Q: What are Layer 2 solutions and why do they matter?
A: Layer 2s are secondary protocols built on top of Ethereum (like Arbitrum or Optimism) that process transactions off-chain and settle them on the mainnet. They reduce congestion and fees while preserving security.
Q: Will Ethereum scale better after the Shanghai upgrade?
A: The Shanghai upgrade primarily enables staked ETH withdrawals and minor improvements. Major scalability gains will come later with full sharding and danksharding implementations.
Q: Is Ethereum still dominant in DeFi despite falling TVL?
A: Yes. Despite a significant TVL drop—from $90B to $23B—Ethereum still holds nearly 60% of total DeFi value locked, far surpassing any competitor.
Q: Can Ethereum maintain its lead against competing blockchains?
A: Despite setbacks faced by rivals like Solana and Terra/Luna in 2022, competition remains fierce. Ethereum’s lead stems from robust security, developer adoption, and network effects—factors likely to sustain its position if upgrades progress steadily.
Final Outlook: A Foundation for the Future
The PoS merge was not an endpoint but a new beginning for Ethereum. It laid the groundwork for greater sustainability, economic efficiency, and long-term scalability.
While market conditions dampened activity in 2022, core fundamentals remain strong:
