Name: Understand EVM circuits and update states in advance: deep dive into Ethereum Evm
Annotation
Predposites are an essential concept of the Ethereum ecosystem, allowing developers to create and implement the Blockchain intellectual contracts without determining the entire knot or wallet. One of the most important aspects of PLOLED Treaties is how they renew their states. In this article, we will investigate how the EVM circuits update the states of predposites and provide insights on the consequences of decentralized programs (DAps) construction on the top of Ethereum.
** What is the preliminary part?
Predposites, also known as Prede Loy or Installing contracts, are special intellectual contracts that can be deployed without the entire node or wallet. They allow developers to create and control pre -processed data in a decentralized manner, which allows the development of complex ethreum programs. One of the main properties of predposites is their ability to dynamically update their states.
As EVM circuits update Predposit states
Ethereum virtual machine (EVM) has several mechanisms that allow you to update the state. The most relevant is the “call” instruction that allows the contract to perform another function in its chain.
When A contract calls another contract with EVM or ETH_CALL, it causes control transition to a call to the SIT contract (the one who initiated the call). This process involves updating the status of the updated contract by calling a new function that can be stored in memory.
Here’s an example of how to illustrate this concept:
Suppose we have a pre -established contract “base” with the following function:
`Solidarity
Pragma solidity ^0.8.0;
Contract l1blockkknum {
Uint256 public feature;
Apply to a public prospectus;
Constructor (address _proxyaddress) {
Proxyaddress = _proxyaddress;
}
Function Getproxy () Public Video Return (Address) {
Return proxyaddress;
}
}
To call GetProxy under a predetermined contract, we would use the following code:
`Solidarity
Pragma solidity ^0.8.0;
the base of the contract {
// ...
ProxyCall (address indexed caller);
}
Constructor (address _proxyaddress) {
BASE._PROXYADDRESS = _PROXYADDRESS;
EMIT PROXYCALL (Tai);
}
When we call Base.Geproxy (), the EVM circuit will update its status by calling the L1Blockknumber contracts on the Getproxy feature. This is done automatically without any manual updates.
Effect on decentralized programs
Understanding how predposites update their states in EVM circuits are very important in developing and implementing decentralized programs (DAps) Ethereum. As part of the Liversing Tesis mechanisms, developers can create more complex programs that are more modified, safe and maintained than traditional node -based solutions.
Some main effects include:
* Decentralized data control
: Predposites allow decentralized data storage solutions that can be updated in real time without required centralized management.
* Improved scaling : Dynamically updating the state, Presteposits can handle large quantities and flow of data, no need to expect gas taxes or total assembly.
* Improved safety
: EVM Call Mechanism provides additional protection against malicious characters who can try to manipulate or steal non -published data.
Conclusion
In conclusion, the EVM circuits update the states of predposits is an essential aspect of the Decentralized Program development and installation Ethereum. By execution of Liversing Tesis mechanisms, developers can create complex and interchangeable DAPP, which are more resistant to centralized control and safer than traditional solutions.
