Ethereum: What is the maximum size of a transaction?

Ethereum transaction size restrictions: Understanding the limits of script

As one of the most popular and widely used blockchain platforms, Etheraum has introduced various features to optimize productivity and provide scalability. One such characteristic is the limitation of the script that limits the maximum size of the transaction to prevent attacks with one transaction (STB).

Script limit: breakdown

In the Ethereum source code, more special in Script.cpp, you will find a order that sets the maximum script size:

`cp

const Uint64_t max_script_size = 1 << 128; // approximately 2^28 bytes

This value represents the upper limit for the total size of all scripts combined within one transaction.

Why is there an upper limit?

The reason for this limitation of the script is to prevent the attacks of STB that occur when a malicious actor tries to force multiple transactions to fail due to the high size of the transaction. If a transaction was too big, it could potentially block other smaller transactions than performance.

In essence, the limitation of the script serves as a precaution against such scenarios, ensuring that even if one transaction is significantly larger than another, they cannot prevent others from completing their transactions.

Other limits on script size

Ethereum also has additional restrictions on certain types of scripts:

* event scripts : These are special types of scripts used to activate events. Their maximum size is limited to 1 byte (8 characters).

* Functional calls : The maximum size limit for functional calls is also limited in the limitation of the script.

Conclusion

In conclusion, the limitation of the Ethereum script serves as a critical security measure to prevent STB attacks and to guarantee scale. Understanding these boundaries, developers and users can work in them to build effective, scale and secure blockchain applications.

An example of using cases:

• Optimization of the intelligent contract code for improved efficiency

• Create limited size scripts to reduce transaction fees or network overload

• Development of decentralized applications (DAPP) that requires low fees transactions

By using these limits of scripts, developers can create healthier, efficient and scales-based Ethereum based systems.
