Resumen de: WO2026022208A1
Smart contracts are self-executable programs that run when certain predetermined conditions are met. The advent of blockchain technologies has provided the means to execute smart contracts in a decentralized manner without the need to trust a central authority: the proper execution of the smart contract is ensured by the agreement protocol of the blockchain on which it is deployed. Blockchain smart contracts, properties of trustless execution, make them an attractive technology for IoT. However, IoT applications often require the processing of large amounts of data that are often difficult to manage in a blockchain environment. In fact, traditional blockchains can only process a few transactions per second, making them unsuitable for the needs of many IoT applications. Additionally, traditional public blockchains require users to pay fees for each piece of data committed to the chain, which makes the use of blockchains too expensive in many IoT case scenarios, as they often involve IoT devices exchanging large amounts of messages. In this thesis, a solution for the execution of smart contracts that improves scalability on blockchain in terms of throughput and cost is presented. The solution is particularly suitable for the IoT, but its generality makes it possible to use it in a variety of scenarios not necessarily related to the Internet of Things.

A system for “tagging” funds identified on a blockchain and associating a weight value therewith. The tagging profile is developed into a propagation profile wherein weight values are inherited from the tagging profile s. Propagation profile funds may be diluted by combining with non-tagged funds, similar to how ink dilutes through water. A spending history of funds of interest is developed based on replaying the funds of interest against the global transaction history of the blockchain. It is determined whether the spending history intersects with the propagation profile, thus determining how closely the two sources of funds are economically to one another. Intersection triggers actions including alert notifications or transfer of funds on the blockchain.

Systems and computer-implemented methods for generating, propagating and handling alert messages on a blockchain network. The alert messages may be generated and sent by an alert administration service to instruct mining nodes to take certain actions, including freezing a transaction outpoint, banning a peer node, invalidating a block, or implementing a confiscation transaction to move assets from a transaction outpoint to another address. An alert handler within the node software at the mining nodes manages the parsing and processing of alerts. Alerts may be sent in P2P message that includes a serialized alert transaction that itself includes the alert message in an output field. A processed alert message results in the alert transaction being included in the mempool and, eventually, the blockchain.

Disclosed are systems and methods for a hybrid cloud-edge computing platform using decentralized networks for solving resource-intensive computation tasks such as machine learning and video processing tasks. In some respects, the cloud-edge computing platform comprises a coordinator cluster and worker nodes partitioned into shards, which include cloud-based networks and edge networks, and which cater to a wide range of computation requirements. The coordinator cluster manages workloads by selecting the appropriate shard and worker nodes to execute tasks based on computed efficiency scores. Worker nodes may be incentivized with rewards such as cryptocurrency tokens for successful completion of tasks. The disclosed architecture also supports the pipelining of multiple tasks in a workload, where the output of one task is used as input for another task. In some respects, the computing architecture includes a blockchain-supported edge network, which enables verifying compute tasks and managing reward distribution for worker nodes using smart contracts.

A user operating an endpoint app chooses to obtain a blockchain-based asset on a target blockchain. The user does not have blockchain transaction credentials for the target blockchain, but does have blockchain transaction credentials for a source blockchain. The endpoint app hierarchically creates target blockchain transaction credentials for the user, using an initial seed of entropy that was used to create the user's source blockchain transaction credentials. A backend component automatically obtains an amount of target blockchain cryptocurrency sufficient to obtain the blockchain-based asset on the target blockchain, in exchange for source blockchain cryptocurrency of the user. The obtained target blockchain cryptocurrency and the hierarchically created target blockchain transaction credentials are used to automatically obtain the blockchain-based asset on the target blockchain, such that once the transaction is completed, the obtained blockchain-based asset is registered to the address of the user's hierarchically created target blockchain transaction credentials.

Techniques are described through which groups of individuals and/or other entities may interface with a data cloud blockchain network and/or cloud-based platform to collectively share data in a secure, controlled manner. Decentralized groups that are connected to the data cloud network may be registered and listed in a searchable directory. Entities that are interested in accessing data associated with a group may browse the directory, execute smart contracts within a blockchain, and track online content interactions of a group in a manner that does not compromise the anonymity of individual group members. Data usage and performance metrics may be tracked on the blockchain network using data cloud services, and the metrics may be written to distributed ledgers within the blockchain network. Smart contracts and chaincode within the network may initiate blockchain transactions based on performance metrics and/or other aspects associated with accessing information about a group.

A permissioned blockchain, using off-chain storage, provides advantages over blockchains that rely on consensus and/or store information within the blockchain. Advantages include enhanced viability, compactness, and the ability to register material with distribution limitations (e.g., military classified). Examples create an immutable public record of data signatures that confirm when data is intact, without distributing the data itself, so that widespread availability of the blockchain (beyond those privileged to see the data) advantageously increases the size of the community that is able to detect spoofing or forgery attempts. A permissioning entity limits submissions to manage blockchain growth, foreclosing problematic material that may risk long-term viability. Examples render blockchain operations resistant to advanced persistent threats (APTs), leverage digital signatures as additional trust elements for high-risk data, link records to track pedigree and enable identification of superseded (obsolete) data, and leverage out-of-band date proof to enable independent verification of integrity and no-later-than data-of-existence.
