The University of Exeter’s College of Engineering, Mathematics and Physical Sciences is inviting applications for a fully-funded PhD studentship to commence in January 2022 or as soon as possible thereafter. The studentship will cover Home tuition fees plus an annual tax-free stipend of at least £15,609 for 3.5 years full-time, or pro rata for part-time study.
This College studentship is open to UK and Irish nationals, who if successful in their application will receive a full studentship including payment of university tuition fees at the home fees rate.
With the emergence of cryptocurrencies, blockchain technologies have become more and more important. Since then, the technology found applications in several domains, such as financial, healthcare, land management, business process management, or even identity management. Smart contract is code which is deployed to a blockchain and which can be executed by sending special transactions to it. As of now, smart contracts are mainly used to automatize financial transactions. However, they have also potential to be used for other domains, such as healthcare.
Since smart contracts are deployed to the blockchain they are visible to everyone and subject to attacks. In June 17 in 2016, for example, a vulnerability in an Ethereum smart contract was exploited resulting in a loss of approximately 3:5 billions of Ether (at that time corresponding to roughly $50 billion). In the healthcare sector, the impact of bugs in smart contracts may be even worse since it may threaten the live of patients.
To address this problem, attempts have been made to support the verification of smart contracts developed in a programming language, such as Solidity. To this end, a security property can be specified for the smart contract and the implementation of the contract in Solidity is then verified against the property. If the verification is successful, the smart contract is guaranteed to satisfy the original property.
Most of the work so far focuses on the verification of single smart contracts. However, modern smart contract applications consist of several smart contracts which often depend on one another. The aim of this project is to investigate how to verify such applications using an interactive theorem prover such as Isabelle and in particular how to apply compositional techniques to minimize the verification effort.
For the purpose of this project, we are looking for enthusiastic and outstanding Computer Science or Mathematics students with a strong background in some of the following topics:
• formal modelling or formal reasoning/verification,
• program analysis or program verification,
• semantics of programming languages,
• theorem proving,
• distributed systems and blockchain
This studentship is open to UK and Irish nationals, who if successful in their application will receive a full studentship including payment of university tuition fees at the home fees rate.
Applicants for this studentship must have obtained, or be about to obtain, a First or Upper Second Class UK Honours degree, or the equivalent qualifications gained outside the UK, in an appropriate area of science or technology.
If English is not your first language you will need to have achieved at least 6.0 in IELTS and no less than 6.0 in any section by the start of the project.
Alternative tests may be acceptable (see http://www.exeter.ac.uk/postgraduate/apply/english/).
