Solution Overview

Problem

Verifying amendments to a set of data, particularly in contract negotiation between parties with no direct communication, is inefficient and time-consuming, especially in Employer of Record (EOR)/Agent of Record (AOR) situations where third-party communication is involved.

Innovation Solution

A method and system utilizing a cryptographically immutable database to process amendments, generate event data items, and synchronize them to maintain a chronological history, combined with artificial intelligence for evaluation and clause generation, ensuring compliance with governing laws.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If amendments are verified through traditional back-and-forth communication between parties, then both parties can reach agreement on contract amendments, but the process takes significant time especially when parties have no direct communication and must communicate via third parties

Engineering Contradiction:
Improveverification of amendmentsVSAvoidtime for communication and verification
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent introduces a blockchain-based intermediary system that acts as a trusted mediator between parties. Amendments are recorded as transactions on the blockchain, creating an immutable and transparent verification mechanism. This eliminates the need for lengthy back-and-forth communication while maintaining reliability, as all parties can independently verify amendments through the blockchain ledger without requiring direct communication or third-party intervention.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical communication system (emails, letters, third-party intermediaries) with a cryptographic system based on blockchain technology. Instead of relying on physical or electronic communication channels that require sequential interaction, the system uses cryptographic hashing and distributed ledger technology to enable instant, trustless verification of amendments, dramatically reducing the time required while maintaining or improving reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If traditional communication channels are used for contract amendment verification, then parties can negotiate and agree on amendments, but the process becomes inefficient particularly in Employer of Record/Agent of Record situations involving third parties

Engineering Contradiction:
Improvecontract amendment processVSAvoidefficiency of verification process
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The blockchain system serves as a neutral intermediary that simplifies the amendment process by providing a single source of truth accessible to all parties. In EOR/AOR situations, the blockchain ledger automatically records and verifies amendments without requiring coordination between multiple third parties, making the process easier to operate while significantly improving efficiency through automated, transparent verification.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a universal blockchain-based verification system that can handle various contract amendment scenarios including direct party negotiations and complex EOR/AOR situations. The same blockchain infrastructure serves multiple functions: recording amendments, verifying authenticity, maintaining audit trails, and enabling independent verification by all parties regardless of their relationship structure, thereby improving both ease of operation and productivity across different contract types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If zero trust parties with no direct communication verify amendments through traditional methods, then they can reach agreement, but the process requires extensive third-party communication and time

Engineering Contradiction:
Improvetrust between partiesVSAvoidcommunication time via third party
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces trust-based mechanical communication systems with a cryptographic verification system based on blockchain technology. Zero-trust parties can independently verify amendments through cryptographic proof embedded in the blockchain ledger, eliminating the need for third-party intermediaries and lengthy communication cycles. The system maintains or enhances trust through mathematical cryptography rather than interpersonal or institutional trust, while dramatically reducing verification time.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Systems and methods for verifying one or more amendments to a set of data include: processing, in connection with a cryptographically immutable database, an amendment to the set of data to produce an event data item characterizing the amendment; storing the event data item in the cryptographically immutable database as a first stored event data item or as a new stored event data item appended to one or more previously stored event data items; synchronizing all stored event data items to produce a current status of the set of data; and outputting the current status of the set of data on a display.
