Real-name electronic bills on blockchain

Glossary

Term DefinitionsBlockchain is a decentralized distributed ledger technology in which multiple computing devices participate in record keeping and jointly maintain a complete distributed database. Electronic Bill is a bill stored and transmitted in electronic form, such as an electronic invoice. Real-name Obtaining is to associate an electronic bill with the user's identity information to ensure that only the real user can obtain their electronic bill. Bill Management Terminal is a terminal device used by users to obtain, query and print electronic bills in real name. User Identity Information is information used to identify the user's identity, such as name, ID number, physiological characteristics, etc. Association Operation is an operation in which a user uses a bill management terminal to associate an electronic bill with his or her identity information. Association Transaction is a transaction that contains a target electronic bill identifier and is used to initiate an association operation on the blockchain. Network Node is a computing device that is connected to a blockchain network and participates in blockchain data processing and maintenance. Smart Contract is an executable code contract deployed on the blockchain, which can be triggered by transactions on the blockchain. Encryption is the process of converting information into an unreadable format to protect information security. Decryption is the process of converting encrypted information back to a readable format using a decryption key. Key Management Platform is a platform for storing and managing electronic bill decryption keys.

Test answer

Blockchain is a decentralized distributed ledger technology in which multiple computing devices participate in record keeping and jointly maintain a complete database. Its characteristics include decentralization, openness, transparency, and immutability. Its application in electronic bill storage can improve data security and credibility.

The decentralized storage method of blockchain can avoid single point failures and improve data security. At the same time, the data records of blockchain are open, transparent and immutable, which can effectively prevent electronic bills from being tampered with and improve data credibility.

Real-name acquisition of electronic bills refers to associating electronic bills with users' identity information to ensure that only real users can obtain their electronic bills to prevent others from impersonating or stealing them.

The bill management terminal is a terminal device for users to perform operations such as real-name acquisition, query and printing of electronic bills. Users can initiate association operations, enter identity information, query electronic bills, and print electronic bills through the bill management terminal.

Users can initiate association operations through the bill management terminal to associate electronic bills with their identity information. The bill management terminal will send the association request to the blockchain network node. After the network node verifies it, the association relationship will be written into the blockchain.

The network node can query the relevant information stored on the blockchain for comparison and verification based on the identity information provided by the user. For example, the user's ID number can be matched and verified with the payer's identity information on the electronic bill.

Encrypting electronic bills stored on the blockchain can protect user privacy and data security and prevent unauthorized access and information leakage.

Users can enter their identity information through the bill management terminal, and the blockchain network node will query the electronic bill associated with it based on the user's identity information and return the query results to the user.

After the user prints the electronic bill, the bill management terminal will associate the number of the paper bill with the identifier of the electronic bill and publish the association relationship to the blockchain for storage. This can prevent users from using the same electronic bill for multiple reimbursements.

The real-name electronic bill acquisition method based on blockchain can effectively improve the security and credibility of electronic bills, facilitate users to manage and use electronic bills, and effectively prevent problems such as fraudulent use and repeated reimbursement of electronic bills.
