Ethereum: Understanding the maximum transaction gas limit
When building -based applications via Ethereum, it is important to effectively manage the transaction gas restriction. The gas limit is the maximum amount of computing resources (CPU cycles and memory) that the transaction can use before stopping the blockchain network.
In this article, we will go into the concept of the maximum transaction gas restriction in Ethereum and explore how it affects your bulk calculations in contracts.
** What is the maximum transaction gas limit?
The maximum transaction gas limit is determined by the Ethereum Virtual Machine (EVM) and is calculated based on several factors:
- Gas price : Gas price on Ethereum network.
- The complexity of the transaction : the number of input parameters, variables and operations in the transaction.

Memory Use
: The amount of memory assigned to the transaction.
EVM uses a formula to calculate the maximum gas limit based on these factors. The resulting value is divided by 2.6.8 (four main gas prices) to determine the maximum gas limit. This means that every time you call the function or fulfill the smart contract for Ethereum, you will pay the current gas price multiplied by the maximum permitted amount.
** How does it affect your bulk calculations?
If the bulk calculations require too long and consumes excessive gas, the network can reject the transaction. This can happen when:
1
Input parameters are large : If the function or smart contract has a lot of input parameters, it can quickly increase the maximum permitted amount.
- Actions are complicated : Performing multiple operations in one transaction can also lead to excessive use of gas.
To avoid this issue, you need to consider the following strategies:
Optimize your functions and contracts : Reduce the number of calculations needed using effective algorithms or data structures.
Use gas efficiency for optimized gas efficient programming languages
: languages such as solidity (official Ethereum language).
Avoid unnecessary calculations : Only the calcus needed to complete the transaction.
Code Example: Calculation of complex value
Let’s say your contract has a feature that calculates complex value:
`SOLIDITY
Function Calculate Value () Public Pure Return (UINT256) {
UINT256 sum = 0;
for (uint256 I = 1; I <10; I ++) {
amount += I * POW (I, 2);
}
The amount of return;
}
In this example, the function is the complexity of O (N), where n is the number of iterations. This means that it can require a significant amount of gas.
To optimize this feature, you could rewrite it using a more effective algorithm:
`SOLIDITY
Function Calculate Value () Public Pure Return (UINT256) {
UINT256 sum = 0;
for (uint256 I = 1; I <10; I ++) {
amount += POW (I, 2);
}
Return amount * I;
}
With the above optimization technique, you can reduce the use of gas and make the contract more efficient.
In conclusion, the understanding of the maximum transaction gas restriction on Ethereum is essential when the building’s circuit application applications. By optimizing features and contracts using gas -efficient programming languages and avoiding unnecessary calculations, you can make sure that bulk calculations are made efficiently and do not use excessive gas.
