Ethereum Deflation
In the Ethereum ecosystem, deflation refers to the phenomenon where the total supply of its native token, Ether (ETH), decreases due to specific mechanisms. Unlike traditional inflation (where supply increases), deflationary mechanisms make ETH relatively scarcer, potentially influencing its market value. Below is a detailed analysis of Ethereum's deflation:
I. Core Mechanisms of Ethereum Deflation: EIP-1559 and the Burning Mechanism
The key to Ethereum's deflation stems from the upgrade proposal EIP-1559, implemented in August 2021, which altered the distribution of transaction fees (Gas fees) on the Ethereum network:
Burning of the "Base Fee" in Transaction Fees
Each transaction's Gas fee is divided into two parts:
Base Fee: Dynamically adjusted based on network congestion, and this portion is directly destroyed (burned), no longer going to miners or validators.
Priority Fee (Tip): A voluntary tip paid to validators (formerly miners) to expedite transaction confirmation.
Example: If a transaction's Gas fee is 100 Gwei (1 Gwei = 10⁻⁹ ETH), with 80 Gwei as the base fee and 20 Gwei as the priority fee, 80 Gwei will be burned, and 20 Gwei will go to the validator.
Mathematical Logic of Deflation
When the network is highly active, the base fee rises, increasing the amount of ETH burned. If the burn volume exceeds the new issuance (e.g., block rewards), the total ETH supply decreases, leading to deflation.
II. The Difference Between Ethereum's "Deflation" and "Net Deflation"
Issuance: Continuously New ETH
After the Ethereum Merge, the consensus mechanism shifted from Proof of Work (PoW) to Proof of Stake (PoS). Block rewards transitioned from "miner mining rewards" to "validator staking rewards," with the current issuance rate at approximately 160,000 ETH per year (validators staking 32 ETH earn an annual yield of about 4%–5%).
Burn Volume: A Dynamic Deflationary Factor
The burn volume depends on network activity:
During bull markets or periods of high Gas fees (e.g., the 2021 DeFi boom, the 2022 NFT craze), daily burn volumes can reach tens of thousands of ETH (e.g., over 100,000 ETH burned in a single day in September 2021).
During bear markets or low-activity periods, burn volumes may fall below issuance, keeping ETH in an inflationary state.
Conditions for Net Deflation
When burn volume > issuance, ETH enters a net deflationary state. For example, if 20,000 ETH are burned in a day and 5,000 ETH are issued, the total supply decreases by 15,000 ETH.
III. Specific Cases and Data on Ethereum Deflation
Historical Deflation Scenarios
As of the end of 2023, more than 3 million ETH had been burned (accounting for about 2.5% of the total supply), while approximately 2 million ETH were newly issued during the same period, resulting in an overall net deflation.
Typical Scenario: In December 2021, the daily Gas fee on the Ethereum network peaked at over 1,000 Gwei, with daily burn volumes exceeding 150,000 ETH—far exceeding the daily issuance (approximately 4,000 ETH)—significantly demonstrating deflationary effects.
Impact of Deflation on Supply
The total Ethereum supply was approximately 118 million before August 2021. As of July 2025, due to deflationary mechanisms, the total supply had dropped to approximately 115 million (assuming burn volumes consistently exceed issuance).
IV. Effects of Deflation on Ethereum and Investors
Potential Impact on ETH Value
Scarcity Logic: Deflation reduces ETH circulation. If demand remains stable or increases, it may drive prices up (similar to Bitcoin's "halving" deflationary effect).
Market Expectation Impact: If investors expect deflation to continue, they may increase holdings, forming a positive feedback loop of "deflation-price increase."
Impact on the Ecosystem
Network Usage Costs: While high Gas fees accelerate deflation, they may deter ordinary users (e.g., small transactions become uneconomical), pushing the development of Layer 2 solutions (such as Arbitrum, Optimism) to reduce mainnet pressure.
Staking Economy: Deflation enhances ETH scarcity, potentially attracting more users to stake ETH (for rewards), strengthening the security of the PoS consensus.
Risks and Controversies
Non-Guaranteed Sustained Deflation: If network activity declines, burn volumes may fall below issuance, halting deflation (e.g., during the 2023 bear market, ETH remained inflationary in some periods).
Fairness Controversy: Higher Gas fees burn more ETH, essentially meaning "the wealthy bear more deflationary costs," which may exacerbate holding disparities.
V. Differences Between Ethereum and Bitcoin Deflation
Deflation Mechanism
Dynamically burns transaction fees, linked to network activity
Halves block rewards every 4 years (e.g., block reward reduced from 6.25 BTC to 3.125 BTC in 2024), fixed cycle
Supply Change
May be inflationary (burn < issuance) or deflationary (burn > issuance)
Sustained deflation, final total supply fixed at 21 million coins
Impact on Price
Deflationary effect depends on network use cases (e.g., DeFi, NFT)
Clear deflationary cycles, more regular market expectations
Economic Model Goal
Balance network fees, reduce miner income volatility, introduce deflationary expectations
Strengthen the "digital gold" attribute through scarcity
VI. How to View Ethereum Deflation Data?
Common Tools and Websites
Ultrasound.money: Displays real-time data on ETH burn volume, issuance, net deflation rate, etc.
Etherscan: Queries base fee burn records in blocks.
Key Indicators
24-Hour Burn Volume: Reflects recent network activity and deflation intensity.
Deflation Rate: (Burn Volume - Issuance) / Total Supply × 100%. A positive number indicates deflation, a negative number indicates inflation.
Conclusion
Ethereum's deflation is not a fixed mechanism but is achieved through the dynamic balance of "burning + issuance" in EIP-1559: when the network is active, burned ETH exceeds new issuance, forming net deflation, which may enhance ETH scarcity and market value. For investors, deflation is one of the important logics for ETH value capture, but it should be noted that it relies on the continuous prosperity of the network ecosystem. For ordinary users, high Gas fees under the deflation mechanism may prompt more people to switch to Layer 2 solutions, promoting the hierarchical development of the Ethereum ecosystem.
