Digital Certificate Processing Reducing Blockchain Storage Burden
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of digital certificates stored in a blockchain leads to a significant burden on storage and computing resources for verification nodes, affecting their operation and user experience.
Innovation Solution
A method and apparatus for processing digital certificates that do not include validity period information, where the digital certificate is recorded to the blockchain only when its effective time is reached, reducing data storage and computational resources needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all historical digital certificates are stored in the blockchain, then the completeness and traceability of certificate records is improved, but the storage resources and computing resources of verification nodes increase significantly
Solution Approach 1:
The patent extracts and removes the validity period information from digital certificates before storing them in the blockchain. This extraction principle reduces the storage size of each certificate while maintaining the essential identity and public key information, thereby resolving the contradiction between record completeness and storage resource consumption.
Solution Approach 2:
The patent applies the discarding principle by eliminating redundant validity period data from certificates during the storage process. The verification system then recovers the necessary verification capability through cryptographic validation, achieving both storage reduction and verification reliability without requiring the original complete certificate data.
2Reliability
If all historical digital certificates are stored in the blockchain, then the traceability of certificate lifecycle is improved, but the computing resources required for verification increase
Solution Approach 1:
By extracting and removing validity period information from certificates before blockchain storage, the patent reduces the computational burden on verification nodes. The verification process only needs to validate the essential certificate components and check against the immutable blockchain record, rather than processing complete certificate data with validity periods.
Solution Approach 2:
The patent performs preliminary processing of certificate data by removing validity period information before storage. This preliminary action reduces the data size that needs to be stored and subsequently verified, thereby reducing the computing resources and energy consumption required for verification operations while maintaining traceability through the blockchain's immutable record.
3Measurement precision
If digital certificates with validity period information are stored, then the accuracy of certificate status verification is improved, but the amount of data stored in the blockchain increases
Solution Approach 1:
The patent extracts validity period information from digital certificates before storing them in the blockchain, reducing the storage amount while maintaining verification accuracy through cryptographic validation of the essential certificate components.

AI summary
A digital certificate processing method includes: receiving a distribution request for a digital certificate, wherein the digital certificate does not contain validity period information; acquiring a verification result for the digital certificate; and according to the verification result, recording the digital certificate which has passed verification to a blockchain.
