Distributed Identity Reputation Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized identity and reputation systems in networked environments lead to power concentration, hinder trust relationships, and are not scalable or reliable in decentralized peer-to-peer networks, where no single node can maintain reputation information for all transactions.
Innovation Solution
A decentralized system that distributes and maintains identity and reputation information among nodes in a peer-to-peer network, allowing nodes to evaluate each other's reputation iteratively and adjust it based on transaction outcomes, using reputation functions and distributed storage of transaction information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized identity and reputation systems are used, then power and control are concentrated, but scalability and reliability deteriorate in decentralized peer-to-peer networks
Solution Approach 1:
The patent segments the centralized reputation system into distributed reputation information stored across multiple nodes in the peer-to-peer network. Each node maintains reputation data for entities it has interacted with, dividing the global reputation management function into local reputation assessments that collectively form the distributed system.
Solution Approach 2:
The patent implements nested reputation structures where reputation information is organized in hierarchical levels. Local reputation assessments are nested within regional or community reputation systems, which are in turn nested within the global reputation network, allowing multi-level trust verification without centralized control.
2Adaptability or versatility
If centralized repositories maintain identity information, then identity management is simplified, but trust relationships and fairness deteriorate
Solution Approach 1:
The patent enables entities to self-manage their own identity information and reputation data. Each entity maintains its own identity attributes and reputation records, which are then distributed to other nodes in the network that interact with it, eliminating the need for centralized identity management while enabling versatile trust relationships.
Solution Approach 2:
The patent introduces distributed identity resolution mechanisms that act as intermediaries between entities. Instead of direct centralized control, the system uses distributed identity resolution services that mediate trust relationships by verifying and propagating identity information across the peer-to-peer network.
3Reliability
If single nodes store all reputation information, then information availability is improved, but network load and single points of failure increase
Solution Approach 1:
The patent segments reputation information storage across multiple nodes rather than concentrating it at single points. Each node stores reputation data for entities within its local network or community, dividing the total reputation information load into manageable segments distributed throughout the peer-to-peer network.
Solution Approach 2:
The patent combines local reputation assessments from multiple nodes to form comprehensive reputation views. When an entity's reputation is queried, the system merges reputation information from multiple source nodes to provide a consolidated assessment, distributing both storage and processing load across the network.

AI summary
In a system and method for the distribution of identities and reputation on a network, identity and reputation information may be distributed among nodes on a network (e.g. nodes on a peer-to-peer network). Embodiments may allow nodes on the network to evaluate other nodes' reputation using the distributed reputation information. Embodiments may allow nodes to iteratively increase confidence in a determined reputation of a node by determining the reputation of nodes that provide reputation information corresponding to the node. Embodiments may allow nodes to adjust a reputation of other nodes using results of transactions and prior reputations. Determined or adjusted reputation information and/or transaction information may be distributed among the nodes on the network. In one embodiment, transaction information may be divided into segments and the segments may be distributed among the nodes on the network.
