Filecoin has integrated Ethereum's improved EIP-1559 mechanism, a significant upgrade originally designed for the Ethereum network. This implementation introduces a base fee for each unit of Gas, which fluctuates based on network congestion. By dynamically adjusting costs, the system effectively manages traffic flow, pushing it toward an optimal target level and enhancing overall network efficiency.
Core Benefits of EIP-1559 for Filecoin
EIP-1559 brings several compelling advantages that align well with Filecoin’s operational requirements and long-term goals.
Improved Efficiency
The new model offers a more effective way to set and compute Gas fees, reducing wastage and optimizing resource allocation across the network.
Enhanced User Experience
Users now benefit from a simpler fee estimation process. Instead of engaging in complex first-price auctions, they can rely on a structured system that predicts costs more accurately.
Critical Message Throughput
WindowPost messages in Filecoin are time-sensitive. EIP-1559 ensures these messages are processed reliably even during high congestion, maintaining essential network operations.
Fair Compensation
Since the entire network shares the burden of processing transactions, EIP-1559 helps ensure fair compensation for the resources consumed.
These benefits made EIP-1559 a natural fit for Filecoin. With only minor modifications, it was incorporated into Filecoin’s core protocol. One key adaptation is the requirement for users to provide an estimated gas limit for transactions before they are executed.
Outcomes and Observations Since Implementation
EIP-1559 is now live on the Filecoin mainnet. Current data indicates that between 100,000 to 150,000 FIL is consumed daily due to network transactions. This adoption has led to two major successes:
Fast Lane for High-Value Transactions
In the past, standard storage messages could sometimes delay urgent WindowPost messages due to fee competition. EIP-1559 provides a straightforward mechanism for participants to prioritize time-sensitive operations without consistently paying premium fees.
Effective Network Capacity Management
The base fee mechanism has excelled at maintaining network capacity near 100% of its target. Over time, users have also improved their accuracy in estimating gas requirements, leading to a reduction in overestimation and burned fees.
Despite these gains, there is still room for refinement. The base fee has shown volatility, with steep rate changes during periods of high demand—often caused by large volumes of new storage deployments. This has occasionally led to critical WindowPost messages being priced out.
Proposed Solutions for Gas Fee Challenges
The Filecoin community is exploring multiple strategies to address pricing instability and congestion.
Dedicated Gas Channels
One proposal is to create a dedicated gas supply for control plane transactions. This would reserve a portion of each block for messages critical to blockchain functionality, ensuring they are never delayed.
Message-Type Fee Structures
Another approach involves adjusting fees based on message type. For example, reducing the cost of WindowPost messages or increasing fees for less urgent operations like PreCommit or ProveCommit messages.
Smoother Base Fee Transitions
The current model sometimes experiences sharp fee spikes. Optimizing the rate of change for the base fee could lead to more predictable and stable transaction pricing.
Advanced Gas Model Improvements
Looking further ahead, several advanced techniques may help alleviate congestion and improve scalability.
Proof Scaling
Innovations such as SNARK batch verification and slashing-based validation could reduce the amount of verification required, lightening the load on the network.
Consensus Scaling
Given current congestion rates, sharding may become a necessary solution. This would split the network into smaller, more manageable pieces, improving throughput and reducing delays.

Future Research and Development
The implementation of EIP-1559 has opened numerous avenues for research and collaboration. There is strong potential for deeper data analysis on network performance and opportunities to partner with other blockchain communities.
Areas of interest include integrating queuing theory into gas models to address inefficiencies, guaranteeing quality of service for certain messages, and exploring methods for introducing cryptographic transactions to the chain.
Frequently Asked Questions
What is EIP-1559?
EIP-1559 is an Ethereum improvement proposal that changes how transaction fees are calculated. It introduces a base fee that adjusts based on network demand, improving user experience and network efficiency.
How does EIP-1559 benefit Filecoin users?
It simplifies fee estimation, reduces delays for critical operations, and helps maintain stable network capacity. Users can submit transactions with greater confidence and lower cost uncertainty.
Why does Filecoin require gas estimation from users?
Because transactions are executed after being included in a block, actual gas usage isn’t known in advance. Users must provide an estimate to ensure sufficient coverage for transaction processing.
Can EIP-1559 eliminate network congestion?
While it significantly improves traffic management, it may not fully eliminate congestion. Additional solutions like dedicated message channels or proof scaling may be needed for optimal performance.
What are WindowPost messages?
These are time-critical messages in Filecoin related to proof-of-spacetime. They must be processed quickly to avoid penalties, making them a high priority for the network.
Is sharding being considered for Filecoin?
Yes, due to increasing transaction volumes, sharding is one of the scaling solutions under evaluation to enhance network capacity and speed.
