Thanks to the ideas of Vitalik Buterin and the contributions of experts such as Ansgar Dietrichs, Barnabe Monnot and Davide Crapis, we are becoming familiar with the concept of “multidimensional gas”. Traditionally, Ethereum has used a unit called “gas” to measure and value the computational efforts required for transactions and operations. This includes calculations such as addition and multiplication, managing data storage, bandwidth, and even complex processes such as generating cryptographic proofs.

Traditionally, Ethereum has used a unit called “gas” to measure and value the computational efforts required for transactions and operations. This includes calculations such as addition and multiplication, managing data storage, bandwidth, and even complex processes such as generating cryptographic proofs.
The recent proposal involves the transition from a one-dimensional to a multidimensional gas model, addressing the inefficiencies of treating different types of computational resources as equivalent. The current system, although simple, does not accurately reflect the different demands that different operations place on the network, which can lead to over- or under-utilization of resources.
Buterin uses a simple diagram to explain that while the gas limit might suggest that a block can safely handle a certain amount of calculations and data, the reality of what is safe can be quite different. This misalignment could potentially allow blocks that are either too safe and underutilized or too risky and overloaded.
With the introduction of multi-dimensional gas on Ethereum via EIP-4844, the network can now process different types of demands more efficiently. This change has already begun to show benefits. Blobs, for example, will allow these rollups to operate much more economically, tripling the transaction volume without significantly increasing the block size, thus maintaining the security of the network.
The update also anticipates future improvements, such as better support for “stateless clients,” a new type of Ethereum client that does not need to store a full copy of the blockchain. These customers rely heavily on testing systems, and the current shift toward multi-dimensional gas could facilitate a smoother rollout of these systems by allowing the network to handle testing more efficiently without compromising security or inflating costs for the users.
This multi-dimensional approach allows Ethereum to adjust how it manages different resources, potentially increasing performance without compromising security. It marks a sophisticated step forward in blockchain technology and promises to make Ethereum more scalable, efficient, and prepared for future demands.
