A SYSTEM AND METHOD FOR PROVIDING DATA PRIVACY IN A BLOCKCHAIN NETWORK

Resumen de: US2025165970A1

The present invention discloses a system (100) for providing data privacy in a blockchain network (20). The network (20) comprises a plurality of participating nodes and a clear-ing-house node. A data logging module (102) of a source node receives a request to conduct a transaction with a destination node, the request comprising transaction details. The data logging module (102) stores the transaction details in an off-chain database (30). An encryptor module (104) receives and encrypts the transaction details to generate a unique identifier. A broadcasting module (106) stores the unique identifier in a ledger and broadcasts the identifier to all the participating nodes in the network (100). A data sharing module (108) receives a private call from the destination node to request access to the transaction details. The data sharing module (108) shares the transaction details with the destination node upon successful validation of the identity of the destination node.

CARBON EMISSIONS TRACKING AND TRADING USING BLOCKCHAIN

Resumen de: US2025166067A1

Climate change poses a significant threat to human well-being, the planet's sustainability, and the global economy, mainly caused by excessive greenhouse gas emissions, particularly CO2. To combat this phenomenon, various tools have been adopted, with the most effective being the carbon emission trading scheme established by the United Nations which created a system that monetizes and reduces CO2 emissions. However, the current system faces multiple challenges, such as manipulation, complexity, and a lack of integrity, preventing it from achieving its ultimate objectives. To tackle these issues, blockchain technology has been proposed due to its distinguishing characteristics of security, traceability, decentralization, and trust. However, blockchain frameworks existing in the literature have been inefficient and inadequate. This research aims to design and develop a practical blockchain system that employs smart contracts and Internet of Things (IoTs) with the use of oracles to solve the problems facing the present carbon emission trading scheme and elevate its operations. The developed smart contracts automate the participating entities' registration and suspension processes and emitters released CO2 measurements as well as carbon credit assignment and trading operations. Our smart contracts were simulated, tested and analyzed where results proved the efficiency, integrity, traceability and security of all processes under the carbon trading market at a reduced cost.
