Understanding the differences between “inicitizeemint” and `inicitizeemint2 in Solana

In Solan, during the initialization of mint accounts for a new program or contract, developers can choose from two methods: `Initizezemint and `inicitizeemint2 ‘. Both methods provide similar functionality, but there are key differences between them.

Initizezemint method

The "Initizezemint" method is a senior API interface that was introduced in Solana in version 1.6. Creates a new MINT account for the program or contract using the pre -defined sequence value. This method is less safe compared to the "Initizezemint2 because it does not require any additional validation or verification.

Here is an example of using the “IniTiSemint” method in Solan:

`Solana

Use Solana_program :: Conct_info;

Use Solana_program :: Ententa_function;

Entry_function! {

program_id = "mint";

initialize_Mint (

Mint_name: conct_info :: Conctinfo :: :: new ("mint_name"),

public_key: account_info :: Pubkey,

Amount: U64

) -> () {

// Mint Account using the pre -defined sequence value

Account_info :: Mintkey :: new (& public_key and conct_info :: Mintvalue :: New (0));

}

}

Initizezemint2 method

The "Initizezemint2 method is a newer API interface introduced in Solana in version 1.7. This method creates a new MINT account for the program or contract and provides additional validation and verification compared to the “initiitizeemint” method.

Here is an example of using the “Inicizezezemint2” method in Solan:

`Solana

Use Solana_program :: Conct_info;

Use Solana_program :: Ententa_function;

Entry_function! {

program_id = "mint";

initialize_Mint2 (

Mint_name: conct_info :: Conctinfo :: :: new ("mint_name"),

public_key: account_info :: Pubkey,

Amount: U64

) -> () {

// His account using the pre -defined sequence value and confirm the public key of the contract

Let Mut Mint = Account_info :: Mintkey :: New (& public_key and conct_info :: Mintvalue :: New (0));

If let err (_) = mint.prc_key.verify (& conct_info :: Pubkey :: new_for_program (program_id) and program_id) {

// Service of verification failure

} otherwise {

// successfully beat the account

Account_info :: Mintkey :: new (& public_key and conct_info :: Mintvalue :: New (0));

}

}

}

key differences

Here are the key differences between “Initizezemint” and “Initizeizeemint2”:

* Safety : The “Initizezemintmethod is less safe due to the lack of additional validation and verification compared to the" initiitizeemint2 "method.

* Validation : The "Initizezemint2 method performs additional validation in the public key of the contract using the” verification “method, which ensures that the program or contract has been implemented in the Solana network. This can help prevent attacks such as phishing and manipulating the code.

* Program identifier

: The “Initizezemint” method requires the transmission of a permanent program identifier in the “Program_id” argument in the macro “.

In summary, programmers should choose the “Initizezemint2` method when creating mint accounts for their programs or Solana contracts. This approach provides additional safety and checking controls that are not available in the older “IniTiSemint” method.
