Research Guide for Private Blockchain Services

Glossary

Term DefinitionsPrivate blockchainA blockchain that is accessible and controlled only by a single user and is used to record usage of that user's device.Blockchain applicationA software running on a user's device that is responsible for collecting usage information, applying privacy settings, and recording data to the blockchain.Usage informationAny data associated with a user's device activity, such as the content of text messages, email addresses, website URLs, social media posts, or media files.Privacy parametersA setting or tag that a user applies to their usage information to indicate whether it should be kept private or can be disclosed publicly.Blockchain data layerA blockchain database maintained by a third-party service that contains private and public data records.Private data recordsRecords in the blockchain data layer that correspond to usage information marked as private.Public data recordsRecords in the blockchain data layer that correspond to usage information that is not marked as private.Public blockchainA decentralized public ledger that records cryptographically hashed proofs of blockchain data layer records.Cryptographic hashesA unique and tamper-proof digital fingerprint created from data using a hashing algorithm.Device identifierData that uniquely identifies a user's device, such as a mobile phone number, IP address, or hardware serial number.User identifiers that uniquely identify a user's credentials, such as a username, email address, or account ID.

Short Answer Question

What is the primary function of a private blockchain?

A private blockchain acts as a private and tamper-proof record of a user's device usage. It allows users to securely store and manage information related to their digital activities while controlling what information can be disclosed publicly.

How do users apply privacy parameters to their usage information?

Users can indicate the level of privacy of their usage information using settings, tags, or options provided by the blockchain application. For example, a user can mark a text message as "private" to prevent it from being included in the public blockchain record.

What is the role of the blockchain data layer in private blockchain services?

The blockchain data layer acts as a central repository for private and public data records. It receives usage information from user devices and organizes it according to the privacy settings of the application. Public data records can then be published and verified on the public blockchain using cryptographic proofs while private data records are kept private.

Explain the purpose of cryptographic hashes in private blockchains.

Cryptographic hashes are used to create tamper-proof digital fingerprints of blocks of data. By hashing usage information and privacy parameters, unique identifiers can be generated that can be included in the blockchain as proof of data integrity and authenticity.

How are device identifiers and user identifiers used in private blockchain services?

Device identifiers, such as mobile phone numbers, are used to distinguish different user devices, while user identifiers, such as usernames, link multiple devices to a single user. These identifiers are used to organize and manage data records in the blockchain data layer and allow users to control usage information for all devices associated with their account.

How do users choose which usage information is recorded to the blockchain?

Users can choose which usage information to record through the blockchain application's interface. They can choose to manually record specific usage instances, such as sending important text messages or visiting sensitive websites, or they can set rules to automatically record all usage information while applying global privacy settings.

How do private blockchains ensure the tamper-proof nature of user usage information?

Private blockchains use cryptographic hash functions and distributed ledger technology to ensure data integrity. Each data block is linked to the previous block, forming a tamper-proof data chain. Any change to any block in the chain will require changing all subsequent blocks, which is virtually impossible.

What is the role of third-party services in private blockchain services?

Third-party services provide the infrastructure to manage and maintain the blockchain data layer and public blockchains. They collect usage information from user devices, process it, and record it to the corresponding blockchain while ensuring that privacy settings are adhered to.

How do private blockchain services benefit users?

Private blockchain services offer users greater control and security over their digital information. They allow users to create tamper-proof records of their device usage, manage their privacy settings, and potentially benefit from sharing their data while maintaining control over their information.

What are the potential applications of private blockchains?

Private blockchains can be used for a variety of applications, including personal data management, identity verification, supply chain management, and digital rights protection. They provide a secure and reliable way to track and verify information while ensuring privacy and control.
