Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized storage systems are expensive and susceptible to unauthorized data manipulation, leading to inaccurate information storage due to their centralized nature and vulnerability to malicious access.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized storage system is used, then data access and management are simplified, but the system becomes vulnerable to unauthorized data manipulation and single points of failure
Solution Approach 1:
The patent divides the centralized storage system into multiple distributed nodes, each maintaining a copy of the ledger. This segmentation eliminates the single point of failure by distributing data across multiple independent entities, thereby improving reliability while the modular nature of distributed nodes keeps individual component complexity manageable
Solution Approach 2:
The patent introduces cryptographic hash functions and digital signatures as intermediaries that mediate between nodes and data. These mathematical intermediaries enable secure, trustless verification of data integrity without requiring complex interpersonal or inter-organizational trust relationships, thus improving reliability without proportionally increasing operational complexity
2Reliability
If a centralized repository is used, then transaction management is centralized and simple, but transaction fees are high and unauthorized access risk increases
Solution Approach 1:
The patent implements self-service validation through cryptographic proofs where each node independently verifies transactions using digital signatures and hash functions. The system serves itself by using mathematical properties of cryptography to automatically detect manipulation attempts without requiring complex external auditing mechanisms, thereby improving security while keeping validation complexity manageable through standardized algorithms
Solution Approach 2:
The patent incorporates feedback mechanisms where nodes continuously monitor the ledger state, verify new transactions against existing state, and propagate validation results across the network. This automated feedback loop provides continuous security verification without requiring complex manual oversight, improving reliability while maintaining manageable complexity through algorithmic automation
3Measurement precision
If clock synchronization is implemented across distributed nodes, then transaction ordering and timestamp accuracy are improved, but network latency and synchronization overhead increase
Solution Approach 1:
The patent performs clock synchronization as a preliminary action before transaction processing begins. Nodes establish synchronized time references in advance through protocols like NTP or blockchain-based time sources, so that when transactions occur, accurate timestamping can proceed without real-time synchronization delays, thus improving measurement precision while minimizing time loss during actual operations

AI summary
In various implementations, a method of managing transactions in a distributed ledger is performed by a first network node that is configured to maintain a distributed ledger in coordination with a plurality of network nodes. In various implementations, the first network node includes a processor, a non-transitory memory, and a network interface. In various implementations, the method includes synchronizing a first clock of the first network node with respective clocks maintained by one or more of the plurality of network nodes. In various implementations, the method includes obtaining a transaction indicator including respective transaction data. For example, in some implementations, the method includes receiving a transaction request from a client device. In various implementations, the method includes synthesizing, by the first network node, a timestamp for the transaction based on the first clock. In some implementations, the timestamp indicates a time that associates the first network node to the transaction.
