Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electronic signature methods are used, then the signing process is simple and quick, but the system is susceptible to fraud and tampering with no tamper-proof transaction history
Solution Approach 1:
The patent introduces a blockchain system as an intermediary layer between traditional electronic signature methods and the signing process. The blockchain records transaction information including document hashes, participant information, timestamps, and signature verification results, creating an immutable ledger that prevents tampering while maintaining the simplicity of electronic signing. This intermediary structure provides tamper-proof transaction histories without requiring participants to directly implement complex cryptographic protocols.
Solution Approach 2:
The patent replaces traditional centralized signature verification mechanisms with a distributed blockchain-based verification system. Instead of relying on a single trusted authority or centralized database that can be compromised, the system uses cryptographic hashing and distributed ledger technology to verify signatures and record transactions immutably across multiple nodes, enhancing security while maintaining operational efficiency.
2Reliability
If blockchain technology is implemented for document signing, then security and tamper-proof transaction history are improved, but transmission confirmation speed may be reduced
Solution Approach 1:
The patent segments the document verification process into distinct components: document hashing, signature collection, blockchain transaction creation, and confirmation recording. By processing these segments in parallel and using asynchronous communication between components, the system maintains high-speed document transmission while ensuring blockchain confirmations are recorded securely. The segmentation allows critical path operations to proceed without waiting for complete blockchain consensus for every minor operation.
Solution Approach 2:
The patent performs preliminary hashing of documents and pre-validation of participant identities before initiating the blockchain transaction process. By preparing cryptographic hashes and verifying participant credentials in advance, the system reduces the time required for blockchain confirmation, as the actual signing and recording processes can proceed with pre-computed data rather than requiring real-time computation during the critical transmission window.
3Ease of operation
If multiple participants sign documents through a centralized system, then coordination is straightforward, but the system lacks transparency and trust among participants
Solution Approach 1:
The patent implements a feedback mechanism where the blockchain system automatically records and broadcasts transaction status, signature verification results, and document hash confirmations to all participants in real-time. Each participant receives immediate feedback when their signature is recorded and when all required signatures are collected, maintaining ease of coordination through automated notifications while providing complete transparency of the transaction history on the immutable ledger accessible to all authorized participants.

AI summary
The systems and methods of the present disclosure can allow for uploading and signing of one or more electronic documents, e.g., by multiple users or participants. Information for each transaction (e.g., uploading, signing, verification, etc.) by the users/participants related to the uploaded and signed document further can be generated and provided to one or more blocks in a blockchain. In addition, the electronic information of the uploaded and signed document can be hashed and provided to one or more blocks in the blockchain. Accordingly, with embodiments of the present disclosure, an immutable transaction history can be provided for uploaded and electronically/digitally signed documents.
