Short answer questions

Please briefly describe the basic process of the proposed transaction method for the blockchain system.

What key information is included in the transaction request? How do the two parties to the transaction sign the transaction information?

How does the central node verify the validity of the transaction request?

How is the transaction confirmation process carried out?

What is the role of the list of transactions to be uploaded? When are transaction records written to the blockchain?

What is the difference between the small transaction blockchain and the main transaction blockchain?

How do users open accounts and recharge?

What role does the transaction amount threshold play in the transaction process?

What information is stored in the account information list of the central node?

Under what circumstances will the transaction be revoked?

Test question answer

The proposed transaction method first receives the transaction request, and then uses the public keys of the two parties to the transaction to verify the transaction information. If the verification is successful, the account balances of the two parties to the transaction are updated, and a transaction confirmation request is sent to the recipient. Finally, the transaction is completed after the recipient returns the confirmation instruction.

The transaction request contains key information such as the account number and transaction amount of the two parties to the transaction. The two parties to the transaction use their own private keys to sign the transaction information to ensure the authenticity and non-repudiation of the transaction information.

The central node uses the public keys of the two parties to the transaction to decrypt the transaction information. If the decryption is successful and the transaction information is consistent, the verification is passed, proving that the transaction request comes from the legitimate two parties to the transaction.

The central node sends a transaction confirmation request to the transaction recipient, and the recipient chooses to confirm or reject the transaction according to his own wishes. If the recipient confirms the transaction, a transaction confirmation instruction is generated and returned to the central node, and the central node finally confirms that the transaction is completed.

The list of transactions to be uploaded is used to temporarily store completed transaction records, waiting to be written to the blockchain. The central node can write transaction records to the blockchain in batches according to preset writing conditions, such as time, quantity or storage space, to improve efficiency.

The small transaction blockchain is specifically used to record small transaction data, while the main transaction blockchain records all types of transaction data. This distinction can effectively reduce the burden on the main transaction blockchain and improve the efficiency of small transaction processing.

Users can open an account by sending an account opening request to the central node and providing identity information. After the account is successfully opened, the user can send a recharge request to the central node to transfer funds to the blockchain account.

The transaction amount threshold is used to distinguish between small transactions and large transactions. If the transaction amount is lower than the threshold, the transaction can be completed quickly without writing to the main transaction blockchain, improving efficiency.

The account information list of the central node stores the user's account number, account balance, public key and other information. The central node uses this information to verify transaction requests, update account balances, and manage user accounts.

If the transaction recipient rejects the transaction or does not confirm the transaction within the set time, the transaction will be revoked. In addition, if the transaction recipient sends a transaction revocation instruction and the transaction record has not been written to the blockchain, the transaction will also be revoked.
