The Truth About Null Variables in Ethereum Storage Tries

Ethereum storage is a crucial part of its decentralized storage solution. When it comes to handling variables that are set to zero, the question arises: are they removed from storage? In this article, we’ll delve into the details and explore why storing zeros doesn’t always provide significant space savings.

Storage Tree Overview

A storage tree is a binary tree-like data structure that Ethereum uses to store and manage storage. Each node in the tree represents a variable or instruction, and each child node corresponds to a specific value associated with that variable. The root of the tree contains all variables, which are typically represented as key-value pairs.

Variables Set to Zero

In an Ethereum program, variables can have a variety of types, including integers, addresses, strings, and arrays. Setting a variable to zero does not immediately remove it from storage. Instead, its value is simply marked as 0.

Why are variables still used in storage attempts

So why don’t variables like “0x1234567890abcdef” or “hello world” simply disappear when they are saved? The reason is the way the Ethereum storage attempt architecture handles variable values.

When a variable is set to zero, its value is not directly saved as 0. Instead, the storage attempt maintains a mapping of variable keys to their corresponding node addresses. This mapping allows for efficient search and storage of variables.

Here are some key points that illustrate why saving zeros does not provide significant space savings:

Representation of variable values: In the Ethereum storage attempt, variable values are represented as binary representations (e.g. 0x1234567890abcdef). To store a zero value, the representation of that particular byte array would have to be changed.

Mapping and Lookup
: As mentioned above, the storage attempt maintains a mapping of variable keys to node addresses. This allows for efficient search and storage of variables. Since zeros do not have a unique address, they cannot be stored like other values.

Trie Node Structure

: Each node in the Ethereum storage attempt is associated with a specific value (or key). When a variable is set to zero, its value is not stored directly in that node, but is marked as 0.

Conclusion

In conclusion, storing zeros in the Ethereum storage attempt does not necessarily provide significant space savings. Using binary representations for variable values and implementing a mapping between variable keys and node addresses ensures that zeros are still an integral part of the storage trie architecture.

If you want to optimize storage usage, consider using variables with unique key-value pairs instead, or using other decentralized storage solutions that don’t rely on binary representations.
