Ethereum: Operation is not valid with the current bundle size
Ethereum Virtual Machine (EVM) is a fundamental engine that runs Ethereum blockchain. One of his fundamental concepts is the operation, which is a way to perform the instructions on Blockchain. However, as stated in [1], the current EVM bundle size may not be sufficient to handle certain operations.
BIP65 and Ble size EVM
The BIP-0065 specification defines the maximum number of bytes that can fit into a beam for surgery. According to this standard, the size of the bundle is 256 bytes. However, in practice, the actual size of the bundle may differ depending on the implementation and the specific case of use.
Example scripts: Operation is not valid
Here’s a simple example of a script that shows what is happening when trying to perform surgery with insufficient space for a bundle:
`c
Pragma Solidity ^0.8.0;
The Simpleoperation {contract
Bytes Memory Data = “Hi, World!”;
function myfunction () public pure refund (bytes) {
IF
// Check that the data size is less than 256 bytes
Hash160
// If true, perform surgery and return the result
Iche
Iche
Iche
`
In this example, we are trying to perform surgery that checks thatdata.length ‘smaller than half of its size. However, since `data.length ‘is currently 32 bytes (a series of” Greetings, the World! “), This operation will not be performed.
What is next?
In order to overcome this restriction, developers can consider using techniques such as:
- Buffering : Store the information to the clipboard before checking its size.
- Dynamic beam distribution : Arrange more memory for each execution to adjust to larger operations.
- Paging : Divide an EVM 8 -page bundle and move between them based on the requirement of the operation.
Conclusion
Although the current size of the Ethereum virtual machine beam may be sufficient for many cases of use, it is crucial to consider these limitations when designing and implementing the blockchain application. Understanding how EVM works and finding ways to optimize their performance, developers can build more effective and scalable blockchain solutions.
