Short Answer Questions

Blockchain technology enhances data security and trust by distributing data across multiple nodes and linking blocks using hash functions. Any tampering with the data will change the hash value, making the tampering easy to detect.

Public blockchains are open to all users, and anyone can join the network and access the data. Private blockchains are limited to authorized users and are usually used within enterprises. Hybrid blockchains combine the characteristics of public and private blockchains, allowing some data to be public while other data remains private.

Blocks are the basic unit of blockchain and contain transaction data, timestamps, and the hash value of the previous block. Blocks are linked to each other by the hash value of the previous block to form an immutable chain.

Access levels define the user's access rights to different parts of the data in the blockchain transaction. Common access levels include public, private, and permissioned.

Customized views refer to displaying only the parts of the data in the blockchain transaction that the user has access to based on the user's access level.

Blockchain technology can be applied to industries such as supply chain management, healthcare, and financial services.

In parking management systems, blockchain can record parking space availability, parking time, and payment information.

In hotel room reservation systems, blockchain can track room reservation status, payments, and customer information.

Blockchain can be used to track the location, status, and maintenance records of autonomous vehicles, as well as manage fleet operations and payments.

Users can use passwords, biometrics, or multi-factor authentication to verify their identity and access blockchain data.

Key Glossary

Term Definitions Blockchain A decentralized, distributed database that records transaction data and creates an immutable record. Block The basic unit of a blockchain, containing transaction data, a timestamp, and a hash of the previous block. Hash function An algorithm that converts data of any length into a fixed-length string, used to ensure the integrity of blockchain data. Access level defines the user's access rights to different parts of data in a blockchain transaction, such as public, private, and permissioned. Customized Views Display only the parts of data in a blockchain transaction that a user has access to, based on the user's access level. Smart Contract A self-executing contract stored on a blockchain that automatically executes when preset conditions are met. Distributed network A network of multiple nodes with no central server control between nodes, and data is stored on all nodes. Encryption The process of converting data into an unreadable format that can only be accessed by users with a decryption key. Immutability refers to the property that data on a blockchain cannot be changed once written, ensuring the integrity and credibility of the data. Hopefully, this guide will help you better understand blockchain-based business inventory systems and methods.
