Understanding from main.cpp and the calculation of ‘log2_workin Ethereum
As a developer who works on Ethereum, it is important to understand how the network works and which different parameters are involved. In this article we will go down in the calculation oflog2_Workand examine what it represents.
What isLog2_Work?
In Ethereum, "Log2_Work" is a parameter used in the consensus salgorithm of the Proof of Stek (POS). Based on the overall work that is necessary to validate new blocks and solve complex mathematical problems, which are referred to as an elliptical curve of digital signature algorithm (ECDSA).
Log2_Workrepresents the Logarithm base 2 of the number of operations that are required to achieve a certain level of safety. Imagine this like a "work rate" that must be fulfilled to ensure the integrity of the network.
Calculation inmain.cpp
The calculation oflog2_Workis implemented in the" Ethereum :: Proofstake "class, especially in the" Calculatelog2work "method:
CPP
Double limestone older () {
// ... calculation ...
Return the work rate / log (2.0);
}
Here is what happens:
- The variable “Workrat” is calculated based on the number of operations that are necessary to achieve a certain level of safety (e.g. 8 million).
- The result is shared by the logarithm base 2 (
log (2.0)), which represents the work rate in relation to bits.
- The result is then returned as "double" so that it can be used in different calculations.
What does->show?
The->>priest, also referred to as the "forward derocence", is a C ++ function with which you can access it from outside of its scope or on functions of an object. In this case, the ->>operator with the member functionTIP ()and the variablesnchainworkis used.
The following means:
- The methodtip ()
returns a "tip" values, which is probably a structure or list that represents different aspects of the blockchain.
- The ->
operator indicates that we want to access the "tip" value from the field of external function (main.cpp).
- By usingTIP () -> nchainwork.GetoUpl ()
we access thetip ()method and then call a "double value from the resulting object.
Example application
To illustrate how this works, we assume that you have a variablelog2_workthat contains the calculated result:
CPP
Ethereum :: Proofstake :: Result log2work;
// ... calculate log2_work ...
You can then use the value log2_work in different calculations by accessing it via the->> operator like this:
`CPP
Double work = 8e6; // sample value
Double Log2Workvalue = Log2Work.GetDouble ();
// Now you can calculate other values based on Log2Workvalue
If you understand how to access and manipulate the “Log2_Work” parameter in your Ethereum code, you can optimize your implementation of proof-of-stake implementations and improve the overall performance of the network.
