Electronic Bulletin Board Information Management System

Electronic Bulletin Board Information Management System

Quiz

Describe the information registration process in an electronic bulletin board information management system.

The information registrant creates an information registration request transaction on their device, which contains a product keyword, bulletin board information, an electronic signature, and a public key.

The transaction is then broadcast to all nodes in the peer-to-peer network.

What validations do nodes perform after receiving an information registration request transaction?

Nodes verify the validity of the electronic signature to ensure that the information is from a legitimate source.

They then check whether the product keyword or code has been used to prevent fraudulent registrations.

What happens if the electronic signature is found to be invalid?

The node will reject the information registration request transaction and broadcast a transaction error to the network.

This prevents transactions containing invalid information or from unauthorized sources from being added to the blockchain.

Explain the role of blockchain in an electronic bulletin board information management system.

The blockchain acts as a secure and immutable database for storing all bulletin board information and related transactions.

Its decentralized nature ensures data integrity and prevents single points of failure.

How does an information registrant associate its public key with a specific product keyword or code?

The information registrant includes its public key along with the product keyword or code in its information registration request transaction.

The recording of this information in the blockchain establishes an association between the registrant and the product.

Describe how an information exploiter accesses information in an electronic bulletin board information management system.

An information exploiter broadcasts an information exploitation request transaction to the peer-to-peer network, specifying the product keyword for the desired information.

Nodes process the request based on their local copy of the blockchain and provide the relevant bulletin board information.

How are nodes rewarded for their contributions to the electronic bulletin board information management system?

Nodes are rewarded by successfully adding new blocks to the blockchain, which involves validating transactions and solving computational puzzles.

This incentive mechanism encourages participation and network growth.

Discuss the benefits of using public and private key cryptography in an electronic bulletin board information management system.

Public and private key cryptography ensures the authenticity and integrity of transactions.

It allows for secure information transfer and protection against unauthorized modifications.

How does an electronic bulletin board information management system solve the scalability issues present in traditional bulletin board systems?

The decentralized nature of peer-to-peer networks allows for the distribution of computational and storage loads across multiple nodes.

This scalability ensures that the system can handle a large number of information registration and exploitation requests.

Outline the key advantages of an electronic bulletin board information management system over traditional bulletin board systems.

Enhanced security, data integrity, and censorship resistance.

Improved scalability, reliability, and fault tolerance.

Reduced administrative costs and increased transparency.
