Ethereum Fusaka Upgrade: Gas Limit to 6000 Million!

Table of Contents

Hi, I'm John. Let's sort through the latest Ethereum upgrades together.

Hi, I'm John. For those of you who are interested in the world of blockchain and cryptocurrencies, today I'll be explaining Ethereum's Fusaka upgrade in an easy-to-understand manner for beginners and intermediate users. This upgrade significantly improves Ethereum's processing power and has been getting a lot of attention in the news recently.

The reason why this topic is important now is that Ethereum, as one of the world's largest blockchains, supports applications such as DeFi (decentralized finance) and NFTs (non-fungible tokens). Fusaka has the potential to increase the scalability of the network and improve transaction speed and costs. Let's start with the basics. For those who are new to cryptocurrencies, choosing an exchange is important. Here is an easy-to-understand explanation of the key points to compare major services:How to Choose and Compare Cryptocurrency Exchanges for Beginners.

Fusaka Upgrade Basics

Fusaka refers to Ethereum's upcoming hard fork (a network-wide update). In the past, Ethereum has periodically enhanced its functionality, such as with the Dencun upgrade. Currently, plans are underway to increase the gas limit (a unit of transaction processing capacity per block) through Fusaka, which is expected to improve the efficiency of the network in the future.

Gas is a unit of fee required to execute transactions and smart contracts (automated programs) on Ethereum. As the gas limit increases, the amount of transactions that can be packed into one block increases, improving overall throughput (processing capacity). For beginners, it's easy to understand if you think of gas as "gasoline."

Gas limit increase: increased to 60 million

According to the latest information, Ethereum developers have approved increasing the gas limit from the current 45 million to 60 million with the Fusaka upgrade. This decision was made at the All Core Devs Execution (ACDE) meeting on September 25, 2025. For the past 3.5 years, the gas limit has remained stable at 30 million, but after the recent increase to 45 million, it is set to expand further.

This change is expected to significantly improve Ethereum's transaction processing capacity and reduce congestion during peak times. Preparations are currently underway on the testnet (a simulation of the production environment), and it is planned to be applied to the mainnet (the production network) in the future.

Latest Updates and Schedule

As of September 26, 2025, Fusaka's first public testnet is scheduled to be activated on October 1, with a default gas limit of 60 million. A shadow fork on the Holesky testnet is also planned.

The mainnet is targeted for launch on December 3, 2025, and is expected to include 11 EIPs (Ethereum Improvement Proposals), including scaling features like PeerDAS (Peer Data Availability Sampling), part of a roadmap to eventually process over 12,000 transactions per second.

Fusaka Benefits and Use Cases

Fusaka will increase Ethereum's scalability and enable users to transact more smoothly. For example, lending and borrowing in DeFi applications, as well as the creation and trading of NFTs, may become faster and have lower fees (gas fees). These improvements will make it easier for beginners to participate.

Specific use cases include:

High-speed transactions on DeFi platforms: Increased gas limits will reduce delays during busy periods and make it easier to manage assets in real time.
Expansion of the NFT market: Creators will be able to efficiently issue and sell large amounts of tokens.
Strengthened integration with Layer 2 solutions (Ethereum's supporting network): Fusaka improvements will support the entire ecosystem.

Risks and Cautions

While upgrades improve network stability, they may require temporary bugs or adjustments during implementation. Security checks have also been important in past hard forks. While the developer community is currently conducting careful testing, users should check for official announcements.

As a note about investing, please note that cryptocurrency prices are prone to volatility, so please make your decisions at your own risk. In terms of regulations, in Japan, please abide by the Financial Services Agency's regulations and remember to take security measures (e.g., use two-factor authentication). We do not provide investment advice, so we recommend that you do your own research.

Tips for using it: Advice for beginners

To benefit from Fusaka, first create an Ethereum wallet (e.g., MetaMask) and try out small transactions. Currently, you can practice on the testnet, so feel free to try it out. Going forward, observe the changes after the upgrade and pay close attention to fluctuations in gas fees.
