Your Sneak Peek into the NV25 Upgrade

The Upload V54

March 31, 2025

The Network version 25 "Teep" upgrade introduces improvements that make Filecoin more efficient and adaptable, simplifying storage provider economics and enhancing developer tooling. Overall these changes make the network more flexible, adaptable and dynamic for builders, storage providers, and storage clients alike. Here’s what to expect when it lands on April 11: 

Key improvements include: 

  • Transient storage via EIP-1153 in the FEVM (FIP-0097); 

  • A simplified fixed-percentage sector termination fee (FIP-0098); 

  • Streamlined data onboarding with the removal of the Batch Balancer and gas constraints (FIP-0100), alongside mainnet activation of F3 parameters.

Keep reading for more details on what these improvements mean.

Support for EIP-1153 (Transient Storage) on Filecoin improves efficiency and security for Filecoin Smart Contract Developers

Support for EIP-1153 on the Filecoin Ethereum Virtual Machine (FEVM) enables compatibility with Ethereum standards — simplifying the process to port contracts from Ethereum to Filecoin. 

By keeping Filecoin in alignment with Ethereum's evolving capabilities, developers can more easily support dual deployment across multiple networks. 

Simplified termination fee calculation to a fixed percentage of the initial pledge makes DeFi applications more efficient and user-friendly on Filecoin

This feature makes DeFi applications more efficient on Filecoin by simplifying how termination fees are calculated for storage providers on the network. Currently, calculating termination fees is computationally expensive and complex. This upgrade replaces this calculation with a predictable percentage that scales linearly for sectors under 140-days-old before stabilizing at an 8.5% fixed fee using a “percentage of pledge” method. 

By giving storage providers better tools to contribute useful storage to the network and manage sectors, network volatility will decrease, improving DeFi developers' ability to more accurately assess the collateral value of a sector when building applications. 

FIP0100 simplifies Filecoin's economic model by implementing a straightforward per-sector fee and removing outdated gas constraints

FIP0100 addresses three interconnected challenges in the Filecoin protocol. First, it eliminates the Batch Balancer fee, which historically introduced variability and unpredictability to onboarding costs. In place of the Batch Balancer, this FIP introduces a new daily fee structure that provides more predictable and proportional economic incentives to storage providers, including reduced onboarding gas usage by up to 30% and more predictable expense models. And lastly, it removes outdated technical limits on batch sizing, which removes limitations on network growth. 

Together, these changes create a more efficient onboarding process and ensure sustainable economics that align incentives for both the network and its participants.

F3 Mainnet activation means 450x faster transaction confirmations

Fast Finality in Filecoin (F3) will speed up finality on the network by up to 450X, making the future of Filecoin fast, secure, and accessible to a wider range of applications. This change is achieved by introducing a new component called GossiPBFT, which works alongside the existing system to rapidly finalize transactions and allows Filecoin to improve its usability across a wider variety of applications while opening the door for new use cases. Fast Finality will be activated following the NV25 Upgrade. For more information about F3’s development, read FilOz's series: The F3 Journey.

Up Next 

NV25 will arrive on Mainnet on April 11, representing the latest step in bolstering the network's storage capabilities and establishing Filecoin as a leading platform in the decentralized web and a broader distribution layer for decentralized services.
