Blockchain architecture, system and method

Blockchain architecture, system and method

It mainly describes a hybrid public-private iteration technology that combines distributed ledgers and micro-identifier chains, aiming to achieve secure data collection and controlled data distribution while complying with global data privacy regulations. Here are the key points of the document:

Blockchain architecture:

Distributed ledger: The system contains a distributed ledger or blockchain for recording and managing transaction data.

Micro-identifier chain (MIDC): Each user has a dedicated MIDC for storing personal identification information and transaction data to ensure data security and privacy.

Hybrid public-private iteration: The system combines the characteristics of public and private blockchains to achieve efficient data processing and privacy protection.

Transaction process:

Transaction request: The user device sends a transaction request, generates a pending transaction object, and publishes it as a pending transaction block on the MIDC of each relevant user.

Execution and verification: The pending transaction object is transmitted to the notarization engine for execution, including terms such as fund transfer. After successful execution, a transaction completion block is generated on the notarization blockchain and transmitted to the MIDC.

Error handling: If a transaction attempt fails, a transaction failure block is generated, indicating that the transaction cannot be completed, and transmitted to MIDC.

Data security and privacy:

Data encryption: The user's personal information and transaction data are stored on MIDC through encryption and can only be accessed by authorized users.

Anonymity: On the notarized blockchain, user data is stored in the form of encoded identifiers to ensure user anonymity.

Anti-chain poisoning mechanism: The system implements an anti-chain poisoning module to prevent malicious transaction blocks from being recorded on the blockchain.

Compliance:

Privacy regulations compliance: The system automatically complies with global data privacy regulations such as GDPR and CCPA to ensure the security and compliance of user data.

Data retention and deletion: According to regulatory requirements, the system can automatically delete or retain user data to ensure compliance.

Health data monitoring:

Medical status module: The system includes a medical status module that allows users to securely submit and verify medical test results, such as COVID-19 test results.

Status display: Users can access and display their medical status, including expiration dates, to prove their health status when needed.

Contact tracing: The system can automatically send possible exposure notifications to the user's contacts while protecting user privacy.

Token ecosystem:

Platform tokens: The system introduces platform tokens, and users can use tokens to purchase services, participate in the staking of data verification nodes (DV nodes), etc.

Governance and voting: Token holders can submit proposals, vote and participate in platform governance, affecting the operation and development of the platform.

Reward mechanism: Users who participate in DV node verification by staking tokens can receive rewards, which motivates users to participate in the ecosystem.

Technical implementation:

Partitioned RAFT replication: The system adopts the partitioned RAFT replication protocol to improve transaction throughput and processing speed.

Smart contracts: Use smart contracts to automatically execute and record transactions to ensure the security and immutability of transactions.

Cross-chain interaction: The system supports cross-chain interaction, and realizes asset transfer and data sharing between different blockchains through side chains and bridging mechanisms.

Describes an innovative blockchain architecture and system that aims to address the shortcomings of existing blockchain technology and achieve efficient, secure and compliant data processing and distribution. By combining key technologies such as distributed ledger, micro-identifier chain, anti-chain poisoning mechanism, privacy regulation compliance and token ecosystem, the system has broad application prospects in multiple fields, especially in healthcare, financial transactions and supply chain management.
