Hybrid Cloud-Edge Computing Architecture for Decentralized Computing Platform

Resumen de: US20260030077A1

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.

PROCESS FOR THE EXECUTION OF SMART CONTRACTS

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.

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 consensus protocol of the blockchain on which it is deployed.
