BLOCKCHAIN TRANSACTION CLEAN-UP SERVICE

Resumen de: WO2025119607A1

Methods, devices, and data structures for processing large volumes of transactions in blockchain nodes. Solutions are provided for transaction clean-up following receipt of a block announcement from another node. In one example, transaction identifiers in a list matching the local candidate block are marked if they match transaction identifiers in the announced block and, once the block is validated, the block assembly service uses unmarked transaction identifiers to build the new candidate block. In other examples, a candidate database of transaction identifiers is built during the mining phase and TxIDs are marked with an array identifier or a node identifier as arrays are announced by other nodes on the network. This may speed clean-up once the block is announced and reduces memory footprint for carrying out the post-solution marking of TxIDs as being included in the solved block.

Latency and computational performance on a blockchain

Resumen de: AU2025203696A1

Blockchain latency is improved by unclogging a mempool, which frees up electronic memory and reduces CPU usage and network bandwidth. Mining data of one or more initial blocks of a blockchain is accessed. The mining data reveals, for each miner, the time delay between individual transactions mined by that miner. A subset of miners is then determined to have lower time delays than miners not in the subset. Thereafter, a different random number is generated for each new block of the blockchain system to be mined. Based on a comparison of this random number and a predefined threshold, either an exploitation phase or an exploration phase is entered for the mining of each new block. In the exploitation phase, mining tasks are assigned only to the subset of the miners. In the exploration phase, mining tasks are assigned to both miners within the subset and miners not in the subset.

The execution of the loop is influenced by the state of the blockchain. Each iteration of the loop that is executed by the computing resource is recorded in a transaction that is written to the blockchain. It is stored as a hash within the transaction's metadata. If the computing resource finds a transaction which contains a hash relating to the loop it accesses the relevant portion of code. The loop contains a conditional statement which enables the computing resource to decide which action to take. The condition may be dependent upon the state of the blockchain or any other data source. The action can be any type of action, on or off the blockchain. Thus, the combination of the computing resource and blockchain provide a solution which is (at least partially) Turing-complete.

UNIFIED IDENTITY REGISTRY

Resumen de: US2025182094A1

Techniques for generation of a unified identity registry are described that support integration and analysis of non-blockchain based user data and blockchain-based user data. A processing device, for instance, monitors an interaction between a client device associated with a user and a digital service provided by a digital service provider. Based on the interaction, the processing device determines a non-blockchain based identifier as well as a blockchain based identifier associated with the user and generates an association between the identifiers.

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.

본 발명에 따른 위임형 행운 증명 기반의 블록체인 합의 방법은 복수 개의 위임 노드를 선정하는 위임 단계; 및 상기 위임 노드가 블록을 생성하기 위한 합의 단계를 포함한다. 상기 위임 단계는, 각 노드가 난수를 생성하는 단계; 난수와 투표정보를 포함하는 투표 트랜잭션을 전파하는 단계; 상기 투표 트랜잭션을 검증하는 단계; 상기 각 노드별로 득표값의 크기를 기준으로 상위 N 개의 노드를 위임 노드로 선정하는 단계를 포함한다. 상기 합의 단계는, 제1 위임노드가 제1 블록을 생성하여 전파하는 단계; 및 다른 위임 노드가 상기 제1 블록의 유효성을 검증하는 단계를 포함한다. 상기 제1 블록에는 논스(nonce)와 행운(luck)의 연결 데이터를 암호화한 제1 증명이 추가되어 있고, 상기 행운은 상기 위임 단계에서 상기 제1 위임 노드가 생성한 상기 난수(이하, '제1 난수'라 함)를 포함한다. 상기 제1 블록의 유효성 검증은 상기 투표 트랜잭션에 포함된 상기 제1 난수를 이용하여 상기 제1 증명의 유효성을 검증하는 것을 포함한다.
