Decentralized On-Chain Publishing Platform and BEI Sovereign Semantic Ecosystem

Resumen de: US20260089019A1

The present invention provides a fully automated, modular publishing platform that seamlessly integrates with content management systems (e.g., WordPress) to capture user-generated content—text, images, and rich metadata—and anchor it immutably onto the InterPlanetary File System (IPFS) and a blockchain registry. Each submission is packaged as structured JSON, streamed to an IPFS node, and its Content Identifier (CID) is recorded in a single atomic smart contract transaction. Beyond simple publication, the system maps every entry to a dynamically versioned “Ecological Module Dictionary” of 1,800+ semantic domains, correlates to 365 industry codes and 999 demand tags, and persists a BEI (Behavior-Economy-Identity) knowledge graph off-chain for multi-dimensional retrieval, DAO-based governance, and tokenized incentives (TimeCoin, BehaviorToken, IdentityCredit). The invention also supports subscription-based module licensing, OEM white-label deployments, and a developer marketplace, forming a sovereign, extensible ecosystem for global-scale, tamper-proof archival and sovereign content trade.

Rendering Blockchain Operations Resistant to Advanced Persistent Threats (APTs)

Resumen de: US20260089004A1

A permissioned blockchain, using off-chain storage, provides advantages over blockchains that rely on consensus and/or store information within the blockchain. Advantages include enhanced viability, compactness, and the ability to register material with distribution limitations (e.g., military classified). Examples create an immutable public record of data signatures that confirm when data is intact, without distributing the data itself, so that widespread availability of the blockchain (beyond those privileged to see the data) advantageously increases the size of the community that is able to detect spoofing or forgery attempts. A permissioning entity limits submissions to manage blockchain growth, foreclosing problematic material that may risk long-term viability. Examples render blockchain operations resistant to advanced persistent threats (APTs), leverage digital signatures as additional trust elements for high-risk data, link records to track pedigree and enable identification of superseded (obsolete) data, and leverage out-of-band date proof to enable independent verification of integrity and no-later-than data-of-existence.
