About Project Ubin – A multiphase journey Project Ubin is a collaborative project between the Monetary Authority of Singapore (MAS) and the industry to explore the use of Distributed Ledger Technologies (DLT) for clearing and settlement of payments and securities.

  8. 8. And why Amazon Managed Blockchain? Ease of creating and managing scalable business networks Quickly create blockchain networks that span multiple AWS accounts. Easily add or remove members and monitor the network Fully managed Choice of Hyperledger Fabric or Ethereum (coming soon) Improves ReliabilityScalable and secure Easily scale your blockchain network as the usage grows. Also, Managed Blockchain secures your network certificates with KMS Choose the right framework for your needs, whether you are building a permissioned or public network Managed Blockchain improves the reliability of the “ordering service,” by replacing the default technology with QLDB. This improves durability. Jointly Presented by:

Instituting key designs for Laws and Regulations  Time Boundaries  Account Controls with multiple-signatures  Contract locks with secure secrets 1 2 3  Smart contracts between buyer and seller are created with time-boundaries  Contracts must be discharged within those specified time boundaries  If contracts are not discharged within time-boundary, design allows to protect investors interest (arbitration and recovery)  Multi-signature conditions starting with 2-of-3 to enable the Exchange (e.g. Securities Arbitrator or Cash Arbitrator) to safe keep Escrow Private Keys  ‘Off-chain’ and ‘out-of-band’ secure Secrets for enhanced security  Enhances security with blockchain-independent transfer of secret Jointly Presented by:

  13. 13. Our Conclusions “Higher Investor Confidence” Design for Arbitrator Role • Designing for arbitrator’s role provide avenue for recourse for disputed transactions • Maintains a central role to monitor and facilitate market functionalities Potential for Round-the-Clock Operations Underlying DvP Design can be further explored for cross-border transactions where time-zone differences could mean a delay in settlement time, exposing participants to unnecessary FX fluctuations and principal risks. • Smart contracts can be used to apply obligations and rights consistently and coherently • Compliance enforcement through smart contracts reduces costs “Flexibility to Reduce Settlement time” • Tokenized currency coupled with smart contracts allows for significant reduction in settlement time on trade by trade basis 1 2 3 4 5 6 • Distributed control prevents account compromise • Layered security with blockchain- independent transfer of secret Enhances investors’ security Multi-Sig, off-chain, out-of-band secure Secrets Project DvP’s underlying design, architecture & benefits can be scaled for other asset classes beyond central bank- issued digital currencies including securities, corporate bonds, commodities etc. and other investor types such as retail etc. Potential broadening of asset classes & investor types “Consistently” applied Rights & Obligations Jointly Presented by:
