Solution Overview

Problem

There is a lack of centralized platforms for individuals to facilitate and track bartering of services and goods, making it difficult for people to exchange services and goods effectively.

Innovation Solution

A distributed ledger system, such as a blockchain, is used to create a marketplace for bartering by allowing users to offer and counteroffer services and goods, with the system storing data on these exchanges and confirming their completion, utilizing APIs and smart contracts for secure and immutable tracking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a centralized platform is used for bartering, then tracking and facilitation of exchanges is improved, but system complexity and cost increase

Engineering Contradiction:

Improvetracking reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a distributed ledger network as an intermediary that enables direct peer-to-peer bartering between users without requiring a centralized platform. The ledger stores and verifies exchange data across multiple nodes, providing reliable tracking while eliminating the need for complex centralized infrastructure and intermediaries.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system enables users to independently create, share, and track their own bartering offers and exchanges through the distributed ledger. Each user's device autonomously records transactions and verifies exchanges without requiring centralized management, reducing system complexity while maintaining reliable tracking through cryptographic verification.

Inventive Principle:

Principle #25Self-service

2Loss of information

If a centralized repository is used for tracking bartering, then exchange tracking is improved, but security and trust issues arise

Engineering Contradiction:

Improvetracking accuracyVSAvoidtrust reliability

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The patent divides the centralized tracking function into multiple independent nodes in a distributed ledger network. Each node maintains a copy of the exchange data, eliminating single points of failure and trust. The segmentation of trust across multiple participants ensures that no single entity can compromise the entire system, while maintaining complete and accurate tracking of all bartering exchanges.

Inventive Principle:

Principle #1Segmentation

3Reliability

If distributed ledger techniques are used, then security and trust are improved, but processing time increases

Engineering Contradiction:

Improvetrust reliabilityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by having users pre-register their bartering offers and exchange preferences in the distributed ledger before actual exchanges occur. This advance registration allows the network to pre-validate data formats and establish trust relationships, reducing the time required for verification during actual exchanges while maintaining security and reliability.

Inventive Principle:

Principle #10Preliminary action

AI summary

Systems and methods described herein track bartering using distributed ledger techniques to, for example, facilitate the establishment of a bartering marketplace that enables users to barter for, and ultimately exchange, services and/or goods with each other. In certain embodiments, a monetary value may be assigned to each service and/or good to be bartered to establish appropriate bartering baselines. In addition, in certain embodiments, additional monetary value exchanges may be tracked for particular exchanges to make sure that the exchanges are fair.
