Title: Solana: Doubts about a get transaction count, not how intended work

Introduction

Solana is a popular blockchain platform known for its fast and safe transactions. When creating a program that interacts with the Solana network, it is important to understand how different functions work. In this article we will examine two important functions in Solana: “Get Transaction Count” and its use with “Slotsuntscribe”. We will also discuss some doubts that we have met when trying out these functions.

Receive root slit number

To get the main slot number in Solana, you can use the “Slotsubscript” function provided by the Solana SDK. Here is an example of how to use it:

`Rost

Use Solana Program :: {

Account_info :: {Next_Account_info, Accountinfo},

Entry point,

Entry point :: program result,

Program_error :: Printerror,

Pubkey :: pubkey,

};

Entry point! (Program);

fn main () -> program result {

// Get the main slot number from the account information

Let (slot_number, _) = Next_Account_info (& Accountinfo :: new_indexed ());

Println! (“Root slot number: {}”, slot_number);

OK(())

}

`

In this example, we subscribe to the “Slot” event on a certain slot (1). If an event occurs with slot number 1, we receive the corresponding account information. Leave us deeper into the use of “Get Transaction Count”.

Use Get Transaction Count

The “Get Transaction Count” function in Solana returns the total number of final transactions for a specific block. To use this function, you must first receive the blocking of the block and then call “Get Transaction Count”. Here is an example:

`Rost

Use Solana_Program :: {

Account_info :: {Next_Account_info, Accountinfo},

Entry point,

Entry point :: program result,

Program_error :: Printerror,

Pubkey :: pubkey,

};

Entry point! (Program);

fn main () -> program result {

// you get the index of the block (1 in this case)

Leave block_index = Next_Account_info (& Accountinfo :: New_indexed ()). Pubkey;

// Call the TRANSACTION COUNT with the block index

Be transaction_count = solana_program :: get_transaction_count (block_index)?;

Println! (“Number of transitions: {}”, transaction_count);

OK(())

}

`

In this example we receive the account information for the second slot (2). Then we call the “Get Transaction Count” with the block index. This function returns a U128 value that represents the total number of final transactions.

Doubt

After trying these functions in our sample programs, we met some doubts:

• Get transactioncount VS GetlotTransactions

  

  : We use Get Transaction Count, but do not receive any result because there are no transactions in Solana. In contrast, “Slotsunsubscribe” serves to work with the “Slot” event that triggers when a new slot is created or an existing updated.

• Block index : The block index returned by next_account_info does not always match the slit number. Instead, we have to use block_index to achieve the right result.

• Transaction number : As we have seen, Get Transaction Count can return zero because there are no transactions in Solana.

Diploma

In this article we examined two important functions in Solana: “Get Transaction Count” and its use with “Slotsubscribe”. We have discussed some doubts that we had met when trying out these functions and gave examples to demonstrate how they are used correctly. If you understand the basics of Solana programming and these functions, you will be on the best way to create powerful programs that interact with the Solana network.
