Probabilistic Blockchain With Confidence Ratings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional blockchain systems are deterministic and lack the ability to handle probabilistic consensus, making them unsuitable for decision-making applications in multi-trust domains where entities have differing opinions or imperfect information, leading to inefficiencies and security vulnerabilities.
Innovation Solution
The implementation of probabilistic blockchains that allow for the generation and verification of blocks with confidence ratings, enabling probabilistic consensus decisions by summarizing transactions and transmitting them across nodes for verification, thereby eliminating the need for centralized trusted authorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional deterministic blockchain systems are used, then the system structure is simple and well-defined, but the system cannot handle probabilistic consensus or make decisions with imperfect information
Solution Approach 1:
The patent extends the traditional deterministic blockchain by introducing probabilistic parameters (confidence ratings, probability distributions) into the block structure and consensus mechanism. This allows the system to represent and process uncertain information while maintaining the underlying blockchain framework.
Solution Approach 2:
The patent separates the deterministic consensus verification from the probabilistic decision-making process. The blockchain structure remains deterministic for security, while probabilistic elements are handled in the application layer through confidence ratings and summary statistics.
2Reliability
If centralized trusted authorities are used for decision-making, then decision-making is efficient and simple, but security vulnerabilities arise and trust is required in a single point
Solution Approach 1:
The patent introduces a probabilistic summary layer that acts as an intermediary between individual transactions and the final consensus decision. This summary layer aggregates confidence ratings and provides a simplified view of the distributed consensus state, reducing the complexity of direct peer-to-peer verification.
Solution Approach 2:
The system incorporates feedback loops where confidence ratings from multiple nodes are aggregated, verified, and used to update the probabilistic state. This continuous feedback mechanism allows the system to converge on reliable decisions while maintaining distributed security.
3Adaptability or versatility
If deterministic blockchain consensus is used, then verification is straightforward and fast, but the system cannot accommodate entities with differing opinions or imperfect information
Solution Approach 1:
The patent implements a configurable confidence threshold that allows the system to accept decisions with partial consensus rather than requiring complete agreement. This enables faster decision-making by accepting a sufficient level of confidence without demanding unanimous agreement from all nodes.
Solution Approach 2:
The system dynamically adjusts the probabilistic state based on incoming transactions and confidence ratings. The consensus threshold and confidence requirements can be adapted based on the specific application needs, allowing flexible trade-offs between decision speed and confidence level.
Data Source
AI summary
A method for constructing blocks to a probabilistic blockchain is provided. The method includes receiving a plurality of transactions from a plurality of agents. Each transaction of the plurality of transactions includes a confidence rating. The method also includes generating a summary based on the plurality of confidence ratings associated with the plurality of transactions. The method further includes generating a block based on the summary and the plurality of transactions. Moreover, the method includes transmitting the block to a plurality of nodes for verification. If the block is verified, the method also includes adding the block to the probabilistic blockchain.
