Blockchain Project Management Token Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current project management systems lack effective enforcement of work order and authorization, often relying on simple communication and outdated document management tools, which can lead to inefficiencies and errors in large projects.
Innovation Solution
A blockchain-based system that generates digital tokens for project contributors, ensuring only authorized users can contribute in the correct order, with contributions verified and stored immutably on a blockchain for accountability and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional document management tools and simple communication methods are used for project management, then the system is easy to operate and understand, but the enforcement of work order and authorization is weak, leading to potential errors and inefficiencies
Solution Approach 1:
The patent introduces a blockchain-based intermediary system that mediates between project contributors and the work order enforcement mechanism. Digital tokens act as intermediaries to control access and verify contributions, while smart contracts serve as automated intermediaries that enforce the work order without requiring complex manual oversight. This intermediary layer provides reliable enforcement while maintaining relative operational simplicity.
Solution Approach 2:
The system implements self-service through automated smart contracts that automatically verify contributions, validate work order compliance, and distribute digital tokens without human intervention. The blockchain network itself performs the enforcement of authorization rules, eliminating the need for complex manual approval processes while ensuring reliable work order adherence.
2Reliability
If digital tokens and blockchain verification are implemented to enforce work order and authorization, then the reliability and security of project contributions are improved, but the system complexity and operational overhead increase
Solution Approach 1:
The patent uses digital tokens as cryptographic copies that represent authorization rights. Instead of complex permission management systems, the system creates and distributes token copies that automatically grant or revoke access based on work order compliance. Each contribution is verified against these token copies, providing security through cryptographic verification rather than complex operational procedures.
Solution Approach 2:
The system replaces manual mechanical verification processes with automated cryptographic verification. Smart contracts automatically verify digital signatures and validate contributions against the work order, substituting human-operated mechanical approval processes with automated algorithmic verification that is both secure and operationally simple for users.
3Reliability
If a blockchain network is used to store and verify project contributions, then the immutability and auditability of the project history are improved, but the processing time and computational resources increase
Solution Approach 1:
The patent extracts only the essential verification data (digital signatures, token validation results, and contribution metadata) to the blockchain, while storing the actual project contributions locally or in distributed storage. This extraction approach provides immutability for the critical verification chain without requiring the entire project dataset to be processed and stored on the blockchain, significantly reducing processing time and computational overhead.

AI summary
A method for project management using a blockchain includes: receiving a project request including a project stream comprised of a plurality of role assignments and an ordering for the role assignments, wherein each role assignment indicates a corresponding public key; generating a first digital token; transmitting the first digital token to a first computing device associated with a public key corresponding to a first role assignment based on the ordering; receiving data from the first computing device including a data file, return token, and digital signature; validating the return token based on the first digital token; validating the digital signature using the public key corresponding to the first role assignment; transmitting the data file to a node in a blockchain network; and transmitting a second digital token to a second computing device associated with a public key corresponding to a second role assignment based on the ordering.
