Decentralized Ledger Patents in Digital Technology

A distributed ledger-based real estate transaction platform that aims to simplify and streamline the process of transferring ownership of real estate properties. The platform uses a distributed ledger, like a blockchain, to store and share property data in a secure and decentralized way. It allows multiple actors like owners, governments, and service providers to access and update the property data using smart contracts. This eliminates redundant document requests and reduces the time and complexity of property transfers by enabling secure, auditable, and permissioned sharing of official data.

Convenient, secure, and reliable payment settlement method for supply chain participants using blockchain. It involves generating digital credit certificates based on trade data between enterprises. These certificates are sent to suppliers to discount payments from downstream suppliers. They can also obtain financing discounts from financial institutions. The updated certificates are sent back to the blockchain node to record transfers and payments. This allows convenient, blockchain-verified payment settlement between supply chain participants.

A post-loan fair processing system using blockchain to improve efficiency, security, and transparency in managing loan risks after disbursement. The system has modules for account management, transaction processing, risk assessment, collaborative work, compliance supervision, and monitoring analysis. Data like loan records, identities, and items are stored on a blockchain ledger. This provides immutability, transparency, and prevent tampering. The modules interact via the ledger to automate, share, and analyze post-loan processes.

Using oracles to access external data like supplier evaluations from third-party platforms and bring it onto blockchain-based supply chain networks. The method involves using a smart contract to call an oracle machine that can access external APIs. The oracle authenticates user identities, decrypts data, and returns it to the smart contract. The smart contract processes and saves the external data alongside blockchain data for comprehensive evaluation. This allows obtaining more complete and objective evaluation data compared to just internal user inputs.

A balanced and available alliance blockchain organization system with improved load balancing and availability compared to existing systems. The system has multiple accounting nodes, backup nodes, private and public gateways. The accounting nodes reach consensus and store the ledger. Backup nodes synchronize the ledger. Private gateways receive client requests from outside the alliance and send them to accounting nodes. Public gateways do the same for client requests from inside the alliance. The private gateway allows fewer business types than the public gateway. This balances load by separating external client requests from internal ones.

A blockchain-based data management system framework to enable secure and efficient sharing of large-scale databases across multiple domains. The framework involves integrating diverse databases with different structures into a unified format suitable for blockchain, cleaning and converting the data, hashing it for integrity, and then recording the hashed transactions on the blockchain. This allows consistent and auditable access to shared data across domains. It addresses challenges like data integrity, query performance, scalability, consistency, and version control for authorized database sharing.

Blockchain-based system for secure and tamper-proof storage and aggregation of asset management records. The system uses smart contracts on a blockchain network to collect and track asset management records like usage history, warranties, etc. A creator publishes a smart contract for the asset containing authorization and write functions. The creator sets their own address as holder initially, then transfers it when delivering the asset. The holder authorizes a writer to write the asset's first certificate value. The writer calculates and writes the value based on the asset's digital file. Verifiers can access the smart contract to calculate and compare their own values against the stored ones.

Product-based intellectual property blockchain network transaction system for facilitating efficient and transparent intellectual property transactions related to products. The system allows buyers and sellers to search, match, negotiate, and transact intellectual property rights associated with specific products. It uses blockchain to provide a secure, immutable, and auditable platform for tracking product-related IP. The system allows buyers to search for products based on IP, and sellers to list products with associated IP. It facilitates IP matching, negotiation, and transaction. The system calculates product-IP value and distributes benefits based on IP contributions.

Shared data storage and copyright protection traceability system using IPFS and blockchain to enable secure and trustworthy data sharing with traceability and copyright protection. The system leverages IPFS for decentralized data storage, and uses a blockchain consensus module to create an immutable and tamper-proof traceability chain. This chain records the sharing process and forms a certificate to prove copyright ownership. The central server coordinates data requests and transfers using smart contracts. The IPFS-blockchain integration enables secure and verifiable data sharing with copyright protection.

Blockchain-based data warehouse system for financial services that allows secure and efficient provision of financial services like credit loans by extracting and verifying only the necessary user data from distributed ledgers. It involves storing user's financial and non-financial data in ledgers and IPFS, encrypting it, and using decrypted links and keys to extract and analyze the data for loan evaluation. This allows automatic verification without resubmitting documents and leverages blockchain for secure and stable credit services.

Blockchain-based data storage method that improves reliability by using continuous reference data to anchor the time of stored data. The method involves creating a genesis block with historical reference data, then generating certificate transaction records based on each certificate deposit using real-time reference data. When verifying the stored certificate, the real-time reference data is parsed and compared to chain data to find the certificate deposit time. This allows proving the certificate existed before storage, mitigating issues with node clock accuracy.

Using a multi-layered hybrid distributed ledger architecture to manage property records in a secure, immutable, and trustless way without overloading the blockchain. The architecture has three layers: a public layer for static property identification, a federated layer for dynamic ownership, and a private layer for sensitive transaction documents. This allows decentralized identification, federated ownership, and private transaction history for properties.

Blockchain-based investment certificate storage system to efficiently support small and micro enterprises by providing a system for tracking and managing investment certificates. The system uses blockchain technology to create a decentralized, transparent, and secure system for tracking investment certificates issued by small and micro enterprises. The certificates contain details like investor identity, investment amount, return rate, etc. This allows investors to make informed decisions and optimize investments. The certificates are deposited on the blockchain, intelligently generated, and stored in a transaction certificate storage module. The blockchain provides a tamper-proof and immutable record of the certificates.
