Project “Bletchley” Vision Microsoft Architectural approach to building an Enterprise Consortium Blockchain Ecosystem

Horizontal SaaS & Adapters Professional Services & Support Our three part Project Bletchley strategy 1 - Build and learn from key partner-driven POCs built on top various blockchain technologies POCs Healthcare Retail & CPG Public Sector Manufacturing Financial Services Media Distributed Ledger Stacks Azure Horizontal SaaS & Adapters 3rd Party 3rd Party DL stack A 1st Party DL Stack 1st Party Ethereum Virtual Machine Adapters Smart Contract-based UTXO + others Middleware Base Platform 3rd Party DL stack B… 3rd Party DL stack C… ….. Industry Solutions Blockchain Resource Provider CryptoDelegate & Cryptlet architecture (secure containers, attestation, etc.) Professional Services & Support Identity & Key Services Crypto Services ML & BI Services Distributed Ledger Gateway Services Blockchain Tools ISVs & Customers Blockchain Marketplace 2 - Grow the blockchain marketplace ecosystem & artifacts together with our partners & customers 3 - Develop key Azure blockchain middleware services to ensure the infrastructure is enterprise ready

Distributed Ledger Stacks 1 – Create a tight feedback loop between POCs & MS engineering to enable quick iterations on our offerings POCs POCs will enable Microsoft to learn quickly, discover customer needs, and galvanize our partners… …influencing BaaS product design and long-term value delivery while saving rework for everyone Blockchain Platform Distributed Ledger Stacks Azure Engineering

2 – Grow a robust set of blockchain offerings in Marketplace 3rd party solutions are already being integrated into our marketplace, we will continue to grow those offerings Everything from fully SaaSified partner solutions, to tiny secured cryptlets, to smart contracts and other blockchain components will be added as they become enterprise ready Organizations and users will be able to add their own or purchase these components from others Allowing Smart Contracts and other blockchain components to be part of the Azure Marketplace will help reduce friction of using blockchain and create incentive to develop on our platform Azure Marketplace with 3rd party solutions, smart contracts, and other blockchain components cryptlet cryplet
