Smart Contracts

Smart Contracts utilize computer technology to automate an agreement

The term "smart contract" is used in different ways according to context: as originally envisaged in the mid 1990s by Szabo, the term "smart contract" embraced automation at many different levels during the lifecycle of an agreement; yet since 2013 it has also been used to describe computer code developed for a scripting functionality provided by some distributed ledger systems (e.g. Ethereum).

Since much of our work is interdisciplinary, and brings together researchers from different groups who use the term "smart contract" in subtly different ways, we use the above (now widely cited) portmanteau definition

Further notes on terminology.

Our research interests are listed below and include (inter alia): legal drafting and legal specification languages (Computable Contracts), privacy, semantics and analysis, Smart Derivatives Contracts, Smart Contract Templates, smart contract code and associated system architectures.

Research

Our research interests are very broad and we interact with a large number of other groups. Our interests currently include:

  • Smart Contract Technology
    • languages and representations for Smart Contracts
    • privacy aspects of smart contracts and smart contract code
  • Smart Derivatives Contracts
    • Smart Contract Templates
    • Institutional workflow
    • ISDA legal document architecture and workflow
    • ISDA Common Domain Model CDM)
  • Smart legal contracts
    • computable contracts
    • legal specification languages
    • legal drafting languages
    • parameterised contracts
    • analysis (e.g. "what-if" analysis, and analysis of contract (in)consistency and coverage)
    • performance (i.e. the discharging of the rights and obligations defined in the smart legal contract)
    • blockchain-enabled contract negotiation
    • engineering smart financial products
    • semantics of smart legal contracts - to enable (i) validation and (ii) computable contracts
  • Validating smart contract code
    • semantics of smart contract code
    • manual validation: validation cases
    • automatic validation: checking semantic models
  • Regulation of smart contracts, and smart contracts to enable regulation (Compliance by Design)
