Efficient storage and verification of data

Efficient storage and verification of data

Background and purpose:

An innovative solution is proposed to address the challenges of data storage and verification on blockchain.

It aims to achieve efficient and secure storage and verification of data and its metadata by combining DLT and cloud computing environment.

System architecture:

The system is deployed in a cloud computing environment and contains at least one processor and memory.

Operate the blockchain interface on behalf of multiple tenants, each of which accesses the blockchain as a participating node.

Transaction processing flow:

Receive transaction requests on the blockchain, which update the value of one or more data elements in the data record.

Verify the updated value in the transaction by executing smart contracts to ensure the consistency and integrity of the data.

If the verification is successful, the transaction is added to a new block of the blockchain to update the data record.

Role of smart contracts:

As an automatically executed program, smart contracts are responsible for verifying the updated value in the transaction.

Prevent unauthorized or erroneous modifications to ensure the security and credibility of data on the blockchain.

Combination of blockchain and cloud computing:

Use the decentralized, transparent and tamper-proof characteristics of blockchain.

Combined with the scalability and flexibility of the cloud computing environment to improve the efficiency of data processing and storage.

Multi-tenant support:

The system supports multiple tenants to access and operate the blockchain at the same time.

Each tenant's data and transactions are independently verified and stored on the blockchain to ensure data isolation and security.

Application areas:

The system can be widely used in areas that require high data security and integrity, such as finance, supply chain management, healthcare, etc.

Technical advantages:

Improve the efficiency of data storage and verification and reduce operating costs.

Enhance the credibility of data through the immutability of blockchain.

Use the scalability of cloud computing to support large-scale data processing and storage needs.

Patent protection:

The patent describes the specific implementation method, technical details and operation steps of the system in detail.

Provides inventors with extensive intellectual property protection to prevent others from using or copying the technology without authorization.

Summary of short answer questions:

What is the core technology?

The core technology is to use distributed ledger technology (DLT) to efficiently store and verify data and its metadata on the blockchain, combined with cloud computing environment to provide scalability and flexibility.

How does the system verify transactions on the blockchain?

The system verifies transactions on the blockchain by executing smart contracts. Smart contracts automatically check the updated values ​​in transactions to ensure that they comply with predefined rules and conditions, thereby ensuring data consistency and integrity.

What are the advantages of combining blockchain with cloud computing?

The decentralization, transparency and immutability of blockchain combined with the scalability and flexibility of cloud computing can significantly improve the efficiency of data processing and storage while ensuring data security.

How does multi-tenant architecture work?

Multi-tenant architecture allows different organizations or users to access and operate the same blockchain network as participating nodes. Each tenant's data and transactions are independently verified and stored on the blockchain to ensure data isolation and security.

What fields are suitable for?

Applicable to fields that require high data security and integrity, such as finance, supply chain management, healthcare, etc., which have strict requirements for the secure storage and verification of data.

What role do smart contracts play in the system?

Smart contracts play a key role in the system. As automatically executed programs, they are responsible for verifying transactions on the blockchain, ensuring that only transactions that comply with the rules are added to the blockchain, thereby maintaining data consistency and security.

What is the main innovation?

The main innovation is to propose an efficient and secure blockchain data storage and verification solution that combines DLT and cloud computing environment, supports multi-tenant architecture, and ensures data integrity and credibility through smart contracts.

How does the system ensure data security?

The system ensures data security through the immutability of blockchain, the verification mechanism of smart contracts, and the data isolation measures of multi-tenant architecture. Any unauthorized or non-compliant modifications will be rejected, thereby protecting the integrity and credibility of the data.
