Personal Blockchain Proof of Use Learning

Key Glossary

Term Definitions Blockchain A decentralized distributed ledger used to record transaction data, which is tamper-proof and transparent. Block The basic unit in the blockchain, containing verified transaction data. Hash algorithm An algorithm that converts data of any length into a fixed-length hash value to ensure data integrity. Hash value Fixed-length data generated by a hash algorithm that uniquely identifies specific data. Personal blockchain A blockchain generated and maintained by a personal device to record personal device usage. Usage information Data describing device usage, such as text message content, email address, website URL, etc. Blockchain command Instructions issued by the user to record specific usage information to the blockchain. Blockchain records the process of adding usage information to the blockchain. Third-party server A server that provides cloud blockchain services and is responsible for collecting, verifying, and publishing blockchain data. Blockchain data layer A database maintained by a third-party server that stores and organizes blockchain data. Cryptocurrency A digital currency that uses cryptography to secure transactions. Device identifier An alphanumeric combination used to uniquely identify a device, such as a mobile phone number, IP address, etc. User identifier An alphanumeric combination used to uniquely identify a user, such as a username, email address, etc. Short Answer Questions

Short Answer Questions

Personal blockchains prove device usage by creating blocks of hashed data containing usage information. These blocks are linked together in chronological order to form an immutable record that can serve as evidence of device usage.

Users can choose which usage information is recorded to the personal blockchain by issuing blockchain commands. For example, users can choose to record specific text messages, emails, or website visits.

The third-party server acts as a cloud blockchain service provider. It collects personal blockchain data from user devices, verifies the data, and publishes it to the public blockchain.

The blockchain data layer is a database used by third-party servers to store and organize blockchain data. It categorizes data based on timestamps and user/device identifiers for easy retrieval.

A hash algorithm is an algorithm that converts data of arbitrary length into a fixed-length hash value. In a personal blockchain system, a hash algorithm is used to generate a unique hash value for each usage information, ensuring the integrity of the data.

Third-party servers can receive cryptocurrency as a reward for providing cloud blockchain services. Cryptocurrency transactions can be recorded on the blockchain, allowing for transparent and secure payments.

Device identifiers are used to distinguish data from different devices, while user identifiers are used to associate multiple devices with a single user.

Personal blockchain systems can be accessed and configured through a web interface. Users can log in to a third-party server through a web browser to view their personal blockchain data and manage their account settings.

Personal blockchain systems can implement multi-layer cryptographic hashing by hashing personal blockchain data and then adding the hash value to the public blockchain. This hierarchical hashing structure enhances the security and immutability of data.

Personal blockchain systems can be applied to a variety of devices, such as smartphones, tablets, laptops, and desktop computers. They can also operate in various network environments such as cellular networks, Wi-Fi networks, and Ethernet.
