State Account Verification Solane: Access to Trust
Solana is a fast and replaced blockchain network that allows decentralized programs (DAPP) to operate in the central organs or mediators. One of the main features of Solana is its ability to store and upload data using a concept called Slot Hash. However, not only data must be stored for the inspection of the bill status before the bag; This requires a reliable approach that ensures the integrity and authenticity of the data.
Problem: Slot bag and check account states
In traditional blockchain networks such as Ethereum, accounts are usually stored in the form of « operations » or « block data ». This allows you to easily check and check your account activity. However, the Solan Nest bags are a new challenge. The nest bags are a unique identifier of the 64th granules that accumulate information on balance, deposits and account withdrawals.
The problem arises when trying to check the status of the account under the bag’s socket, without being able to load the factual data stored in blockchain. In other words, you cannot directly access your account data from the bag socket.
Solution of Trust: Admission Evidence
The solution to the confidence of this problem is the use of evidence of admission. Adoption evidence gives users the opportunity to prove that they have successfully performed a specific operation or actions, not in fact and without protecting the basic data « blockchain ». Evidence of receiving is essentially an indirect way to verify accounts before time.
Revenue evidence works by creating cryptographic implementation evidence (PoE) connecting the sender’s address to the recipient’s address and operation information. This evidence can be used to reconstruct the status of the account from the slots of the bag, allowing users to check their account balance without access to basic data.
Example of income evidence
Here is an example of rust implementation:
`Rūdys
Use STD :: Collection :: Hashmap;
Use Solan_Rogram :: {{
foreign
the entrance point,
Msg,
Program_Error :: Preyprogmerror,
};
Use Solan_Sdk :: Keypair :: KeyPAIR;
FN Main () {
// Create a model key and account
Let Public_Key = Keyboard :: New (Your_public_key_Here).
Flight Private_Key = Keyboard :: New (Your_private_Key_Here).
// Initialize proof of approval
Let Mut compraut_pore = water support :: New (public_key.clone (), & private_key);
// Create a model operation with an account ID and bag jack
Let « account_id = » some_account_id « .to_string ();
Let slot_hash = « some_lot_hash_here » .to_string ();
// Pull Account Data from Operation (this example is not listed)
// …
// Create verification evidence using the pulled data and a bag socket
Let the reception_provise_data = get durable:
// Verify that evidence of approval is valid and corresponds to primary data
Compliance acceptance_provizo_data.Verify () {) {
Ok (true) => Println! (“Successfully verified income evidence!”),
ERR (ERR) => Msg! (« {} », Err),
}
}
`
In this example, we will create evidence of confirmation using the « appropriate access library ». We will then use the evidence of approval to create account data from the bag socket.
Conclusion
The account of the account condition before the bag holds the Solane requires access to without reliability, which includes the provision of evidence of approval. Admission evidence is provided by an indirect way to verify the status of an account that allows users to reconstruct the basic data without direct access to it. After installing admission evidence, developers can form decentralized programs (DAPP), which depend on the unique features of Solana while maintaining safety and integrity.
