In 2020, Ethereum celebrated its fifth anniversary by stepping firmly into the spotlight. What began as a foundational smart contract platform has evolved into the beating heart of decentralized finance (DeFi), driving unprecedented network activity and user growth. This surge is reflected in key metrics: active addresses are up 137.93%, daily transactions have surged 170.39%, and average gas fees have skyrocketed 16-fold in USD terms. Behind these numbers lies a thriving ecosystem fueled by stablecoins, decentralized exchanges (DEXs), and yield-generating protocols.
Rising Network Activity: Users and Transactions Soar
Ethereum’s resurgence in 2020 isn’t just about price—it’s about usage. According to CoinMetrics, ETH rose from $130 at the start of the year to over $300 by late July, marking a 148.62% increase. But beyond market sentiment, on-chain data reveals a deeper story of adoption.
Daily transactions climbed from 466,500 in January to 1.26 million in July—an increase of 170.39%. A pivotal moment came on June 16, when Compound launched its COMP governance token, igniting the liquidity mining boom. Within a week, daily transactions crossed the 1 million threshold for the first time and have remained above that level ever since.

Similarly, daily active addresses jumped from 231,800 to 551,500, a 137.93% rise. Since July, the network has consistently hosted over 500,000 active users per day—a level previously reached on only six occasions before this year. This sustained user engagement signals strong organic growth, driven largely by DeFi applications offering yield, trading, and lending services.
Gas Fees Skyrocket: Network Congestion Reflects Demand
With increased usage comes congestion—and higher costs. The average gas price rose from 11.7 Gwei in January to 96.7 Gwei by July 27, an eightfold increase in native units. When converted to USD, the impact is even more dramatic: the average transaction fee jumped from $0.12 to $1.92, a staggering 16-fold rise.
At these levels, users paying the network average are already qualifying for “Fastest” confirmation speeds on ETH Gas Station, which required just 82 Gwei at the time. This suggests most participants are prioritizing speed due to competitive interactions within DeFi protocols, where timing can affect yield outcomes.
CoinMetrics data paints an even starker picture: average fees hit $1.90, up from $0.08—representing a 22x increase. More telling, over half of all transactions on July 27 paid more than $0.93 in gas fees, compared to just $0.04 earlier in the year—a near 25x jump.
DeFi Protocols Dominate Gas Consumption
The primary drivers of this fee surge? Decentralized finance applications.
According to ETH Gas Station, the top gas-consuming contracts over a 30-day period were dominated by DeFi platforms:
- USDT (ERC-20): ~$1.97 million in gas fees
- Uniswap V2: ~$649,000
- 1inch, IDEX, Synthetix: Each exceeding $100,000
These figures include not only trades but also contract interactions such as approvals, deposits, and withdrawals—core actions in yield farming and automated market making.
While legitimate DeFi projects lead the list, some high-gas users like SmartWay Forsage and MMM have been linked to Ponzi schemes, highlighting risks alongside innovation.
Miner Revenue Jumps 392% Amid Soaring Fees
Amid rising fees and network demand, Ethereum miners have seen explosive revenue growth. Daily miner income climbed from $1.34 million in January to $6.57 million by July—a 392% increase.
This growth far outpaces network hashrate expansion, which rose only 32.05% from 147.41 TH/s to 194.65 TH/s. The disparity indicates “excess profits” for miners, as block rewards remain fixed while transaction fees have surged.
Gas Fees Now Constitute Over One-Third of Income
Historically, Ethereum miner revenue came mostly from block subsidies (2 ETH per block). Today, transaction fees play a much larger role.
By July 27, gas fees accounted for 36.46% of total miner revenue—up from just 2.92% at the start of the year. This shift marks a structural change: Ethereum is transitioning from a subsidy-driven to a fee-driven mining economy.
Compare this to Bitcoin, where transaction fees made up only about 2.8% of miner income in 2019—highlighting how much more economically active Ethereum has become.
Mining Landscape: Concentration and Competition
Ethereum’s mining ecosystem shows both centralization at the top and long-tail fragmentation below.
Over the past three months:
- SparkPool held 30.48% of hashrate
- Ethermine controlled 21.21%
- Together, they commanded 51.69% of total network power
Other notable players include F2Pool, SpiderPool, and NanoPool—all holding over 5% share.
Yet beneath this concentration lies decentralization: 136 unique miners participated, with 47 mining only one block and 85 mining fewer than 100 blocks. This long tail suggests lower barriers to entry and a less mature mining landscape compared to Bitcoin.

Uncle Rates and Empty Blocks: Efficiency vs. Profitability
Two key performance indicators—uncle block rates and empty block rates—reveal strategic differences among pools.
- SparkPool: Uncle rate of 19.20%, empty block rate of 23.87%
- Ethermine: Uncle rate of 16.44%, empty block rate of 10.83%
High uncle rates suggest efficient propagation but also reflect competition; high empty block rates indicate pools may skip transaction inclusion to reduce latency and mine faster—a trade-off between gas income and block success probability.
Interestingly, SparkPool reduced its empty block rate from 23.87% (3-month avg) to 16.84% (last 3 days), possibly adapting to higher fee environments. Meanwhile, Ethermine’s empty block rate rose to 18.58%, suggesting divergent optimization strategies.
FAQ: Understanding Ethereum’s Surge in Activity and Costs
Q: Why did Ethereum’s gas fees increase so dramatically in 2020?
A: The surge was primarily driven by explosive growth in DeFi applications like Compound, Uniswap, and yield farming protocols. Increased user activity led to network congestion, pushing users to bid higher gas prices for faster transaction confirmations.
Q: Are high gas fees good or bad for Ethereum?
A: In the short term, high fees reflect strong demand and economic activity—positive signs for network health. However, sustained high costs can deter casual users and hinder scalability, underscoring the need for Layer 2 solutions and Ethereum 2.0 upgrades.
Q: How do DeFi apps contribute to gas consumption?
A: DeFi platforms require frequent smart contract interactions—such as swapping tokens, depositing collateral, or claiming rewards—all of which consume gas. Complex multi-step transactions common in yield farming further amplify usage.
Q: Is Ethereum mining still profitable in 2020?
A: Yes—miner revenue grew by nearly 400%, with gas fees now making up over a third of income. Despite moderate hashrate growth, rising ETH prices and transaction volumes created favorable conditions for profitability.
Q: What does the dominance of SparkPool and Ethermine mean for decentralization?
A: While two pools control over half the hashrate, the presence of many small miners maintains some decentralization. However, high uncle and empty block rates raise questions about fairness and efficiency in block propagation.
Q: Will Ethereum 2.0 solve the high fee problem?
A: Ethereum 2.0 aims to improve scalability through sharding and proof-of-stake, reducing congestion over time. Until full rollout, Layer 2 solutions like rollups offer immediate relief by processing transactions off-chain.
