CARBON EMISSIONS TRACKING AND TRADING USING BLOCKCHAIN

Absstract of: 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.

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.

IMPROVED GOSSIP-PROTOCOL-BASED METHOD, DEVICE, EQUIPMENT AND MEDIUM FOR INCENTIVIZING BLOCK PROPAGATION

Absstract of: US2025158981A1

An improved gossip-protocol-based method, a device, a piece of equipment and a medium for incentivizing block propagation. By improving the Gossip protocol and embedding block propagation rewards, the block forwarding process is accelerated.

By combining the signature chain structure with the block generation process, the rewards are ensured to be truly and reliably distributed. A block propagation reward distribution strategy is designed to prevent forwarding nodes from adding pseudonyms in the propagation path. Therefore, the method can reduce the blockchain stale rate and enhance the scalability and consensus performance of the blockchain by accelerating block propagation in the presence of selfish nodes, and addresses the problem that selfish nodes refuse to forward blocks to save communication consumptions in the current blockchain network.
