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.

She sends her data to a storage provider, Bob, while retaining her sample(s) and the resulting Merkle root value(s). Alice does not tell Bob which sample(s) she has chosen, or the operations she has used in the variations, or any inputs to the operations. Alice can delete her original copy of the data. At a later date, Alice can verify that Bob still has her complete data and in its original state by requiring him to perform the same operation on the same data sample, calculate the root value of the resulting Merkle tree and send it to her. If Bob's root value matches Alice's root value, then Bob must have an original and complete copy of Alice's data otherwise he would not be able to calculate the correct Merkle root value.

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. The designed signature chain structure records the block forwarding path and ensures that the path information is not tampered with. 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.

A network-based service creates a smart contract on a blockchain on behalf of a user who has a loan or a subscription that requires installment payments be collected by a provider from the user and provided to creditor of the loan or subscription. The smart contract associates a default account of the user with a first access token and non-default registered other accounts of the user with a second access token. The smart contract when presented with the access tokens from a provider determines whether the payment due can be satisfied from a current balance of the default account and if so, transfers the payment from the default account to the provider. If the default lacks sufficient funds for the payment, the smart contract proportions the amounts taken from each of the accounts to reach the amount due and transfers the amount due to the provider.

This invention presents a structured framework for developing and refining smart contracts essential for B2B blockchain ecosystems. It harnesses computational resources, including processing units and memory, to optimize the adaptability and robustness of smart contract generation processes. Central to this system is the Modular Asset Lifecycle Descriptor (ALD), facilitating a direct, state-transition methodology that simplifies the smart contract generation process, diverging from traditional code parsing approaches. A unique feedback loop, drawing inspiration from aviation industry strategies, enables continuous improvement and refinement, enhancing the system's resilience and integrity. The utilization of modular printer units further augments the system's flexibility, allowing for the seamless integration of community-driven enhancements and iterative updates. This architecture heralds a transformative approach in smart contract generation, championing enhanced clarity, efficiency, and resilience in the dynamic realm of blockchain technologies.

Methods, devices, and a data structure for processing large volumes of transactions in blockchain nodes without using a mempool. Incoming transactions are validated and added to a candidate block. Transaction identifiers are added to an ordered set of transaction identifiers in an array until complete. The completed array and its Merkle root are propagated to other nodes. A placeholder transaction may be used in the first array in place of a coinbase transaction and its Merkle path may be determined to enable replacement of the placeholder transaction by the coinbase transaction during mining. Subsequent arrays are appended to the consolidated list of transaction identifiers are they are completed to continuously build a growing candidate block for mining.

The present invention discloses a method for optimizing a consensus mechanimn of a blockchain based on a trust degree and relates to the technical field of blockchains. The method includes: constructing a trust degree data set of each consensus node according to attributes of each consensus node in the blockchain; classifying and evaluating the trust degree data set through a trained C4.5 classification model to determine the trust degree level of each consensus node; endowing each consensus node with a corresponding voting weight according to the trust degree level, and managing and controlling the Byzantine problem emerging in a running process of the master node by a smart contract; sending a block reguest log of the consensus node to a Kafka message queue and completing‘ a checkpoint protocol based, on an FIFO characteristic; and detecting the consensus performance of a blockchain system by means of a Hyperledger Fabric alliance chain.
