The upcoming Ethereum EIP-1559 upgrade has sparked intense debate across the blockchain community. While many anticipate a transformative shift in transaction pricing and network efficiency, others remain skeptical—especially given the real-world performance of similar mechanisms in other networks. One of the most telling precedents comes from Filecoin, which implemented an EIP-1559-like fee structure early in its mainnet launch. By analyzing Filecoin’s experience, we can gain valuable insights into what Ethereum might expect post-upgrade—both the opportunities and the overlooked challenges.
What Is EIP-1559?
Ethereum Improvement Proposal 1559 (EIP-1559) introduces a revolutionary change to how transaction fees—commonly known as gas fees—are calculated and distributed on the Ethereum network. Instead of relying solely on a competitive bidding system, EIP-1559 establishes a dynamic base fee that adjusts according to network congestion.
Here’s how it works:
- The base fee is automatically adjusted per block based on usage: if block occupancy exceeds 50%, the base fee increases; if below, it decreases.
- This base fee is burned, permanently removing ETH from circulation.
- Users can add a small priority fee (or "tip") to incentivize miners to include their transactions faster.
The goal? To make gas pricing more predictable, reduce volatility, and ultimately enhance user experience by shifting control from miners to users.

Filecoin’s Real-World Implementation of EIP-1559
Filecoin was one of the first major blockchains to adopt an EIP-1559-style mechanism at mainnet launch. According to Juan Benet, Filecoin’s founder, the implementation has delivered two key benefits: improved transaction prioritization and dynamic message capacity management.
However, real data paints a more complex picture.
Over recent weeks, Filecoin’s base fee has fluctuated between 1 to 6 nanofil, causing significant swings in total gas costs. For miners adding 1 terabyte of storage, this translates to 5–12 FIL per transaction—a substantial operational expense.
Even more striking is the distribution of fees:
- Over 99.99% of gas fees are burned
- Miners receive only a negligible portion as rewards
For example, on March 2, 2021, a standard FIL transfer incurred around 0.0017 FIL (~$0.40)** in fees, while critical operations like *ProveCommit Sector* cost up to **0.146 FIL (~$36). Despite these high costs, network congestion remains a persistent issue—especially during peak mining activity.
Key Observations from Filecoin’s Model
From months of live operation, several patterns emerge:
1. High Fee Volatility Persists
Despite dynamic adjustment, gas fees on Filecoin remain highly volatile due to sudden spikes in network usage—primarily driven by miner activity rather than end-user demand.
2. Miners Bear the Brunt
Unlike typical users, Filecoin miners actively bid up base fees to ensure their storage proofs are included in blocks quickly. This behavior is economically rational—they’re investing in future mining rewards—but it drives up overall network costs.
3. No Relief from Congestion
Contrary to expectations, EIP-1559 did not resolve message backlogs. In fact, periods of rapid network growth often coincide with severe congestion and soaring fees.
4. Deflationary Pressure Is Real
With daily burns reaching 100,000–150,000 FIL, the circulating supply has trended downward. This deflationary pressure enhances the scarcity and long-term value proposition of FIL.
Comparing Filecoin and Ethereum: Why Outcomes May Differ
While both networks use similar economic models, their use cases and user behaviors differ fundamentally.
| Factor | Filecoin | Ethereum |
|---|---|---|
| Primary Transaction Type | Miner-generated sector commitments | User-driven dApp interactions & transfers |
| Gas Fee Drivers | Storage expansion & proof submissions | DeFi trades, NFT mints, token swaps |
| Payment Motivation | Investment in future mining returns | Immediate execution needs |
On Filecoin, high gas payments are part of a capital investment strategy—miners pay more today to earn more tomorrow. On Ethereum, users pay gas for immediate utility, making them far more sensitive to cost fluctuations.
This distinction suggests that EIP-1559 may have different impacts:
- On Ethereum, where demand comes from diverse decentralized applications, base fee burns could lead to sustained deflationary pressure.
- However, during high-demand events (e.g., NFT drops), users may still face unpredictable costs—even with a dynamic base fee.
- Network congestion is unlikely to disappear overnight. Scalability will still depend heavily on Layer 2 solutions like rollups and sidechains.
What Ethereum Can Learn from Filecoin
Based on Filecoin’s experience, here are three realistic expectations for Ethereum post-EIP-1559:
1. Transition Toward Deflationary Supply
As more ETH is burned through transaction fees than issued as block rewards, the net supply could shrink—especially during high-usage periods. This enhances ETH’s store-of-value characteristics and supports long-term price appreciation.
2. Limited Short-Term Relief on Congestion
Just like Filecoin, Ethereum won’t see immediate congestion relief. If anything, increased predictability might attract even more usage, temporarily exacerbating bottlenecks until Layer 2 adoption accelerates.
3. Reduced Miner Revenue
Estimates suggest miner income could drop by 20–35% after EIP-1559, since the majority of fees are burned instead of being awarded to validators (in PoS) or miners (in PoW). This shift has already sparked resistance but aligns with Ethereum’s broader vision of decentralizing economic control.

Frequently Asked Questions (FAQ)
Q: Does EIP-1559 eliminate high gas fees?
A: No. It makes fees more predictable and reduces extreme volatility, but during peak demand, users still need to pay higher priority fees for fast confirmation.
Q: Will ETH become deflationary after EIP-1559?
A: Potentially yes. When the amount of ETH burned exceeds new issuance, the net supply decreases. This has occurred multiple times since EIP-1559’s activation.
Q: How does burning gas fees affect miners?
A: It significantly reduces their income. Miners only earn the small tip portion of the fee, which can lower profitability—especially on congested networks.
Q: Can EIP-1559 solve scalability issues?
A: Not directly. While it improves fee market efficiency, true scalability depends on Layer 2 technologies and future upgrades like sharding.
Q: Is Filecoin a perfect analogy for Ethereum?
A: Not entirely. Filecoin’s miner-dominated traffic skews fee dynamics. Ethereum sees more diverse usage, so outcomes may vary in degree and impact.
Q: What happens to burned ETH?
A: Burned ETH is permanently removed from circulation via a smart contract that sends it to an unspendable address. This reduces total supply and increases scarcity.
Final Thoughts
Filecoin’s implementation of an EIP-1559-style model offers a compelling case study: fee burning works, deflation is achievable, but network congestion and high costs persist under heavy load.
For Ethereum, EIP-1559 represents a pivotal step toward a more efficient and economically sustainable network. However, users should temper expectations—true scalability lies beyond a single upgrade. The path forward combines protocol-level reforms with growing Layer 2 ecosystems.
As Ethereum evolves, monitoring metrics like daily ETH burned, average base fee, and miner revenue share will be crucial for assessing real-world impact.
