Blockchain P2P Content Sharing Illegal Content Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blockchain-based P2P content sharing networks face challenges in managing and deleting illegal or bad content due to their distributed nature, making it difficult to block or remove such content effectively.
Innovation Solution
A user device and an administrator device are configured within the blockchain network to generate, verify, and block illegal content through P2P communication, using block information and an artificial intelligence model to identify and manage reported content, ensuring that illegal content is deleted and its distribution is halted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content is distributed and stored in multiple electronic apparatuses in a blockchain network, then content sharing capability is improved, but the ability to delete or modify illegal content deteriorates
Solution Approach 1:
The system segments content management into two distinct parts: (1) immutable blockchain storage for verification and tracking, and (2) mutable local storage on user devices for deletion. When illegal content is identified, the system generates deletion instructions that are stored on the blockchain, while actual deletion occurs locally on each user's device. This segmentation allows content to be widely distributed for sharing while maintaining the ability to delete it from individual devices.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of deletion instructions and verification codes. Instead of directly modifying distributed content, the system uses blockchain-stored deletion instructions as intermediaries that trigger local deletion actions. These intermediaries bridge the gap between the immutable blockchain ledger and the mutable local content storage, enabling centralized deletion control in a distributed system.
2Extent of automation
If a blockchain network operates without a central administrator for P2P content sharing, then system autonomy and decentralization are improved, but the ability to manage and block illegal content deteriorates
Solution Approach 1:
The patent implements multi-functionality by enabling regular user devices to perform administrator-like functions. Users can report illegal content, and their reports are verified and processed by the decentralized network. The system universally allows any participant to contribute to content moderation through reporting mechanisms, while maintaining system autonomy without requiring a dedicated central administrator for every operation.
Solution Approach 2:
The system establishes feedback loops where users report illegal content, the network verifies these reports through blockchain consensus, and deletion instructions are generated and distributed back to relevant devices. This feedback mechanism enables autonomous content management by continuously cycling through detection, verification, and correction actions without central intervention, while still achieving effective illegal content blocking.
3Reliability
If content verification and blocking mechanisms are added to a blockchain P2P network, then illegal content blocking capability is improved, but system complexity increases
Solution Approach 1:
The patent extracts complex verification and blocking logic from individual user devices and places it in the decentralized blockchain network itself. Instead of requiring each device to independently analyze and block illegal content, the system extracts these functions to the network level where consensus mechanisms handle verification. Individual devices only need to implement simple reporting and instruction-following capabilities, significantly reducing device complexity while maintaining strong blocking capability at the network level.

AI summary
A user device configured to operate in a blockchain network includes a communicator; a memory; and a processor configured to: based on a peer-to-peer communication based content being received from at least one of a plurality of external apparatuses constituting the blockchain network, generate, through the communicator, block information related to the received content, store the generated block information in the memory, and transmit, through the communicator, the generated block information to the blockchain network; based on a user command for reporting the received content being received, transmit information on the reported content to the blockchain network; identify, based on verification on the reported content performed by at least one administrator device from among the plurality of external apparatuses, whether or not the reported content corresponds to an illegal content; and based on the reported content corresponding to the illegal content, block distribution of the received content.
