Using Blockchain in University Management Systems

Using Blockchain and smart contracts for secure data provenance management

Blockchain technology has evolved from being an immutable ledger of transactions for cryptocurrencies to a programmable interactive environment for building distributed reliable applications. Although, blockchain technology has been used to address various challenges, to our knowledge none of the previous work focused on using blockchain to develop a secure and immutable scientific data provena...

Untangling Blockchain: A Data Processing View of Blockchain Systems

Blockchain technologies are gaining massive momentum in the last few years. Blockchains are distributed ledgers that enable parties who do not fully trust each other to maintain a set of global states. The parties agree on the existence, values and histories of the states. As the technology landscape is expanding rapidly, it is both important and challenging to have a firm grasp of what the cor...

Threshold Signatures for Blockchain Systems

Blockchain, introduced as the backbone of the Bitcoin cryptocurrency, is an emerging technology. Abstracting the currency logic away opens Blockchain to endless applications from finance to healthcare and Internet of Things. Asymmetric cryptography and more specifically digital signatures are a key component of the blockchain system. In this work, we introduce threshold signatures for the Hyper...

Risks and Opportunities for Systems Using Blockchain and Smart Contracts

Blockchain-Assisted Crowdsourced Energy Systems

Crowdsourcing relies on people’s contributions to meet productor system-level objectives. Crowdsourcing-based methods have been implemented in various cyber-physical systems and realtime markets. This paper explores a framework for Crowdsourced Energy Systems (CES), where small-scale energy generation or energy trading is crowdsourced from distributed energy resources, electric vehicles, and sh...
