“…10, the vINCI platform uses blockchain-a proven technology for healthcare applications (Kuo et al 2017)-in order to ensure privacy while preserving provenance and openness. Blockchain technologies have demonstrated adequate scalability (Leal et al 2020) and an intrinsic ability to support dynamic source reputation (Hirtan et al 2020) and consistent quality of service (Leal et al 2021) in complex sensor networks. Within the vINCI platform, patients are recognised as owners of their own data, with full control over it.…”

One of the most important lifestyle risk factors for many chronic conditions in the older age, low physical activity has shown to have significant impact on the sustainability of national welfare in many developed countries. Technology-based assisted living solutions can effectively be used to enable older adults to optimise their health-related quality of life, as well as to promote an active and healthy longevity. This paper describes vINCI—an interdisciplinary research project to actively support assisted living for older adults via state-of-the-art assistive technologies—which seamlessly deploys an ambient intelligence environment to integrate wearable devices, networking, software, and personalised services. It entails clinical validation and feedback at home and residential care facilities via a cloud microservices platform. Underpinned by blockchain technologies, multiple wearable devices, apps, and cameras securely capture the anonymised facets of different life events, whilst machine learning models create individualised user profiles to analyse any decrease in the perceived health-related quality of life typically associated with old age. Two controlled pilots are being conducted with 80 participants at older adult facilities in Romania and Cyprus. By incorporating clinical validation and feedback from specialised practitioners, the vINCI technologies enable older adults not only to self-evaluate their physical activity level, but also to change their behaviours and lifestyle in the long-term.

Blockchain-Based Decentralized Virtual Power Plants of Small Prosumers

et al. 2021

The deployment of small-scale renewable energy sources will transform the management of energy grids towards more decentralized solutions in which the prosumers will have a more active role. Regulatory and market barriers are driving the implementation of virtual aggregation models in which the small-scale prosumers work together on a larger scale to gain benefits that could not be obtained on an individual basis. In this paper, we propose to use public blockchain and self-enforcing smart contracts to construct Virtual Power Plants (VPPs) of prosumers to provide energy services. A model has been defined for capturing the prosumer level constraints in terms of available energy profiles and energy service requirements enabling their optimal aggregation in hierarchical structures. A lightweight decentralized solution for VPPs construction is implemented using smart contracts enabling its efficient running on the public blockchain. Smart contracts are encoding the model constraints and are defining functionalities for prosumers to initiate or join a VPP implementing the complete chain of Offer-Operate-Measure-Remunerate actions. The VPP will be managed on top of a distributed ledger technology offering decentralized functionality for tracking and validating the delivery of energy based on the blockchain transactions and for energy and financial settlement, the remuneration being done according to the amount of energy provided by individual prosumers. Experimental results show that the proposed solution runs successfully on the public blockchain with good execution time and can address Balancing Responsible Party requests for additional generation. The overhead in terms of gas consumption and transactional throughput stays within reasonable boundaries.

“…The authors then compared the performance of two different versions of HLF v0.6.0 and v1.0.0 [9]. Rouhani and Deters [10] investigated Ethereum's performance on a private blockchain by examining two of the most popular Ethereum clients: PoW-based Geth and PoAbased Parity. According to the results, Parity is faster than Geth in terms of transaction processing under various workloads.…”

Permissionless or public Distributed Ledger Technologies (DLTs) provide full decentralization and transparency. The performance evaluation of permissionless Distributed Ledger Technologies is difficult due to their dynamic nature. This paper focuses on the performance evaluation of permissionless Ethereum DLT. Public test networks highly resemble the main network and capture the dynamic nature of permissionless DLTs. The paper proposes the BloodTrace application to trace the donated blood from the donor to the patient. The performance is evaluated by deploying the BloodTrace smart contract on the public test network Ropsten. The data collection for the calculation of the performance parameters can be performed in two ways: i) RPC based method ii) Log-based method. RPC based method involves polling the blockchain for each transaction data. The log-based method involves the collection of logs and fewer RPC calls to the Blockchain. The probabilistic nature of transaction confirmation is also taken into consideration while calculating the Latency (Finality) by analysing the effect of block confirmations on the latency. The evaluation results are then compared with the results obtained by the Hyperledger Caliper Benchmarking tool as it is using RPC based approach for calculation of performance parameters.
