** Ethereum: Does the precompile address affects the root of the state?
When building a layer 2 stack (L2), it is not uncommon to meet ISSUSUS with the generation of state roots. One of the most common problems is that the pre-filled addresses used by Ethereum EIP-1559 and other intelligent contract standards can affect the behavior of the state root.
In this article, we will deepen the reason why precompile addresses could have an impact on the state root and we will explore how to optimize the L2 stack for better results.
** What is a state root?
Before immersing yourself in the problem, we quickly examine what is a state root. The state root is a structure of abstract data that contains all the information necessary for the Ethereum Blockchain to perform intelligent contracts. It is essentially a compact representation of the entire state of the blockchain at a certain moment.
Because pre -fillers addresses the state root
When using a pre -filled address, it means that a compiled contract is used that contains logic for your specific application. These pre -filled addresses are essential functions that return the balance of an Ethereum account or other relevant data. When these accounts interact with the blockchain, their state is updated in State_root.
The problem arises when the precompile address is used to calculate thestate_rootor a contract.State_root ‘is generated using the output of the compiled function and the input parameters from the signature of the contract. However, if you use a pre -filled address that depends on the sales or data of the other accounts, the root of the resulting state may not carefully reflect the current state of the blockchain.
Impact on the L2 stack
In an L2 stack, multiple contracts are performed on several blocks of space on the main chain. State_root 'is used to calculate the status of the new block by connecting it to the state of the previous block. However, if a contract uses a pre -filled address that depends on the sales or data of the other accounts, the resulting state root can be influenced.
For example, consider a simple L2 stack with two contracts:
The contract to use the contract B 'as input.

When contract is carried out on a new block, calculate the state root by connecting to the state of the previous block, use the pre -filled address from 'Contract A'. However, ifcontracts B 'depends on the sales of other accounts (for example,` contracts there is) for its calculations, the root of the resulting state may not carefully reflect the current state of the blockchain.
Optimization of the generation of state roots
To optimize the L2 stack and minimize problems with pre -fillers that affect the root of the state:
- Use deterministic contracts : instead of using pre -filled addresses that defend on the sales or data of other accounts, opt for more deterministic contracts that can directly calculate their outputs.
- Avoid the functions dependent on promoting
: if possible, avoid the functions of Promommio that depend on the sales or data of other accounts. This will reduce the probability of errors and guarantee an accurate generation of the state’s roots.
3 This can help to minimize errors and prevent problems caused by pre -filled addresses.
By following the best thesis practices, you can optimize your L2 Stack and improve the performance and accuracy of your intelligent contract applications on the main Ethereum chain.
Conclusion
In this article, we have explored because pre -fillers addresses on the root of the state of contracts in an L2 stack. We also discussed strategies to optimize the generation of state roots to minimize problems with deep functions or balances of accounts. By applying these best practices, it is possible to create more reliable and efficient intelligent contract applications on the main Ethereum chain.
