1. Internal Team in Barclays Accelerator – January to April 2016 Introduction Demo Day Complex challenge – each bank maintains it own Aim – showcase a vision of the future: the lifecycle of a separate ledgers and systems, huge duplication of “smart” standardised financial product effort and cost Software demo – prototype web application to edit Solution – shared ledgers and smart contracts templates, edit agreements, enter trades, affirm trades, Piece in jigsaw puzzle – smart contract templates and view trades Our focus – legal document templates to facilitate History in the making – first public demo of prototype smart contracts application on R3’s prototype Corda platform • connect legal text to business logic, simplify Venue – The O2 in London, audience of 800, largest legal documentation processes FinTech demo day ever anywhere • drive standards adoption via reusable Collaboration – Barclays Investment bank, R3, University templates College London, ISDA, Société Générale, Techstars • mutualise costs via common components General benefits – cost reductions, efficiency improvements, risk reductions UNRESTRICTED 9

2. First summit The R3 Smart Contract Templates Summit • held in London and New York in June 2016 • presentations by R3, Barclays, ISDA, University College London and Norton Rose Fulbright • over 60 participants from over 20 organisations UNRESTRICTED 11

3. First research paper Smart Contract Templates: foundations, design landscape and research directions • position paper presenting vision • foundations (terminology, automation, enforceability, semantics), e.g.: “A smart contract is an agreement whose execution is both automatable and enforceable. Automatable by computer, although some parts may require human input and control. Enforceable by either legal enforcement of rights and obligations or tamper-proof execution.” • design landscape (parameter sophistication, code commonality, long-term research) • joint Barclays-UCL authorship • publicly released in August 2016 ert UNRESTRICTED 12
