Key Highlights
- In the latest post on X, Vitalik Buterin revealed his plan for the Ethereum blockchain to move away from a general “scaling everything” to “targeted optimization.”
- He has proposed a plan for Ethereum where the network’s gas limit is increased 5X, but simultaneously, the gas cost for computationally inefficient operations would also be raised by 5X
- In the next month, the blockchain is going to get a major upgrade, known as Fusaka
Vitalik Buterin, founder of the Ethereum blockchain, has shared a post on X (formerly Twitter), where he hinted at possible upcoming changes on the blockchain.
Expect continued growth but more targeted / less uniform growth for next year.
eg. one possible future is: 5x gas limit increase together with 5x gas cost increase for operations that are relatively inefficient to process
Potential targets for such increases (my current view):… https://t.co/FkiTxJnEAq

In his tweet, Vitalik mentioned a new direction for the blockchain network, where they planned to move away from a general “scaling everything” to “targeted optimization.”
Vitalik shared a plan to significantly increase the network’s capacity while deliberately making certain inefficient operations more expensive.
One of the major highlights of this tweet was his promise to boost the total number of transactions on the network. “One possible future is: 5x gas limit increase together with 5x gas cost increase for operations that are relatively inefficient to process,” he said.
In simple words, it will raise the cost for activities that require a lot of computational resources and slow the network for everyone.
To achieve this state, they will focus on specific technical functions that are known to cause congestion. These include operations that create new data storage, calls to overly large smart contracts, and complex mathematical calculations.
Buterin stated that the network should expect “continued growth but more targeted” in the coming year. The main purpose behind this plan is to encourage high-value transactions while cutting off high-value transactions while discouraging spam and poorly designed applications. It will ensure that the network stays decentralized for all users.
Vitalik Buterin Proposes Safe Scaling Approach
This is not the first time Vitalik has talked about this long-standing issue. Earlier this year, he supported a smaller increase to the network’s gas limit, calling it a safe scaling because it was enabled by key software upgrades. These upgrades drastically reduced the amount of data nodes needed to store to ensure that it could handle more load without compromising.
“Just a year after the community started pushing for higher gas limits, Ethereum is now running with a 60M block gas limit. That’s a 2× increase in a single year — and it’s only the beginning,” Toni Wahrstätter stated in a post on X.
The main part of his argument has been the need for a stronger base layer to support the ecosystem of Layer 2 networks like Arbitrum, which now handle the vast majority of activity.
Buterin has argued that the main Ethereum chain must be robust enough to allow millions of users to exit these Layer 2s quickly and affordably if needed.
Ethereum Prepares for Major Fusaka Upgrade in 2026
The biggest blockchain network is preparing for the next major upgrade, known as Fusaka, which is scheduled for early December 2025. This hard fork is the network’s largest single update in years and is designed to support Buterin’s plan.
This upgrade will allow nodes to sample small pieces of data instead of having to download and store everything, which can increase efficiency. As a result, the amount of data each block can carry is expected to increase by over 130%.
This will reduce congestion for Layer 2 networks and is expected to cause a major drop in user transaction fees. Major financial analysts called Fusaka an under-appreciated catalyst that could multiply the value captured by the Ethereum network.
The network is preparing for another major upgrade in mid-2026, which will introduce features to resist certain forms of market manipulation and enhance user privacy.
