Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blockchain systems face challenges in efficiently processing transactions related to worker timecards due to high computational costs and latency, particularly in consortium blockchains, which require secure and instant approval mechanisms for payroll calculations.
Innovation Solution
A unique timecard identifier is generated, incorporating an onboarding identifier and check-in/check-out data, which is processed through edge networks to trigger authorization, utilizing a consortium blockchain with smart contracts and distributed private keys for secure and instant payment approval, reducing computational load on the blockchain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain processes payroll transactions directly, then security and immutability are improved, but computational cost and latency increase
Solution Approach 1:
The system divides the payroll processing function into two segments: (1) blockchain nodes verify the unique timecard identifier and smart contract conditions to ensure security and immutability, and (2) edge network devices perform the actual payroll calculation and parameter processing. This segmentation allows the blockchain to maintain security while reducing computational burden on the network.
Solution Approach 2:
The patent introduces an edge network as an intermediary between workers and the blockchain. The edge network device receives the unique timecard identifier, processes payroll parameters, calculates payments, and returns results to the blockchain. This intermediary handles computationally intensive tasks, reducing energy consumption and latency while the blockchain maintains security through verification.
2Reliability
If consortium blockchain verifies all transactions, then security is improved, but processing speed decreases
Solution Approach 1:
The system performs preliminary verification by embedding the unique timecard identifier with cryptographic signatures during worker onboarding. When payroll transactions occur, blockchain nodes can quickly verify the pre-established identity and authorization without performing complex consensus algorithms, thus improving processing speed while maintaining security.
Solution Approach 2:
The edge network acts as a trusted intermediary that pre-processes and validates payroll parameters before submitting to the blockchain. This reduces the verification burden on consortium blockchain nodes, enabling faster transaction processing while maintaining security through the edge network's validation role.
3Measurement precision
If payroll calculations are performed on blockchain, then accuracy is improved, but latency increases
Solution Approach 1:
The edge network device serves as a computational intermediary that performs payroll calculations using pre-validated worker data from the unique timecard identifier. This approach achieves accurate payroll processing by leveraging the cryptographic guarantees of the blockchain identity system, while completing calculations off-chain to minimize latency.
Solution Approach 2:
The system replaces the mechanical process of on-chain computational verification with cryptographic verification of pre-computed values. The unique timecard identifier contains embedded cryptographic proofs that allow blockchain nodes to verify payroll accuracy without performing intensive calculations, thus reducing latency while maintaining precision.

AI summary
Apparatuses, systems, and methods described include receiving by a node in a blockchain, a unique timecard identifier including an onboarding identifier and check-in or check-out data. If the unique timecard notifier includes check-out data, the transaction value includes at least an authorization value calculated based on the onboarding identifier and the check-in and the check-out data. The action may further include contacting an oracle to verify the worker's identity and location to authorize an instant transfer of value.
