Blockchain On Azure
- 1. 21st April 2018 - Global Azure Bootcamp - Malta Blockchain On Azure Johan Zammit j.zammit@smartstudios.io
- 2. Agenda - What Is Blockchain? - Why Blockchain? - My Favourite Top 10 Uses Of Blockchain - Example : Supply Chain - How Does It Work? Consortium, Mining - Why Azure? - Ethereum + Smart Contracts - Demo – Blockchain in the Azure Marketplace -> Ethereum On Azure - Solution Architecture = On Chain + Off Chain - Blockchain 3.0 with Cryplets + Coco Framework Note : Some of the slides and images are from Microsoft presentations about blockchain
- 3. What Is Blockchain? A distributed ledger that is Transparent Immutable Secure
- 4. What Is So Special About Blockchain? Trustless Trade. Distributed Trustless Consensus. It’s all about trust. Trust built on mathematics. For the very first time in history we can safely transact without a middleman, remove possibility of double spending, and have immutability in open systems. I do not trust you or any middleman – you do not trust me or any middleman – but I can still safely transact with you.
- 5. Blockchain Establishes A Secure, Shared Source Of Truth
- 6. Why Blockchain? - No middleman. Think of p2p file torrents. - Less fraud through transparency and immutability - Faster transactions – T+0 (settled same day) - Reduce costs through automation + no middlemen - Possible new revenue streams. New business models

- 8. PRODUCER SMART CONTRACT The package has to be maintained at Temperature < 10º C Humidity < 65% FOOD PROCESSOR WAREHOUSE CARRIER 1 CARRIER 2 SMART CONTRACT UPDATED Origin 8ºC 60% SHARED LEDGER The conditions of the contract have been violated. Carrier 2 is liable for penalty as the temperature of the package when it reached the retail store was above the prescribed limit RETAIL STORE 11ºC 66% Milk producer supplies Milk to Food Processing Company The milk product is sealed in an IoT enabled package for shipping The terms of shipping are registered using a smart contract on the Blockchain Warehouse 9ºC 64% Carrier 2 9ºC 64% Store 11ºC 66% Carrier 1 delivers milk to Warehouse 1. The temperature of the package is within prescribed limits on arrival. The package is still within prescribed temperature limits when Carrier 2 arrives to retrieve it for delivery to Retail Store. Example : Supply Chain
- 9. Blockchain – Network Types
- 10. Blockchain – Network Types
- 11. What Is Mining? Proof Of Work : miners will work for next block reward Example : Find a nonce that produces a hash that starts with 5 zeros New Block = Nonce + Hash Of Prev Block + New Transactions
- 12. Fast deployment through templates Tools & ecosystem that you know Scalability of nodes Why Azure? … and there is an even bigger more important reason …
- 13. Ledgers Partners Dev Tools Why Azure? - Multiple blockchains to mix and match - Key partners like Consensys
- 15. Why Ethereum? - Largest decentralised software platform - 75% of ICOs are tokens on Ethereum - Smart Contracts in Solidity As opposed to Bitcoin, Ethereum has a “state database” of accounts which hold a balance External accounts – users – receive and send ether …. Execute contracts … can have a balance in Ether Contract accounts – instance of a contract template – each time a smart contract is deployed a new account is create. A smart contract too can hold a balance.
- 16. Less Costs Less Delays Less Risk Of Non Delivery Smart Contract Automation A smart contact is an application that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference
- 17. Demo
- 18. Blockchain on the Azure Marketplace https://azuremarketplace.microsoft.com/en-us/marketplace/apps/category/blockchain
- 20. Demo Setup We used a readily available template We’re using standard Azure compute, networking, and storage services Passphrase is used to encrypt your private key. Each consortium member is given a subnet with a set of mining nodes Mining nodes - Mine transactions into block, collect fees Transaction nodes - a set of load-balanced TNs with which an app can interact to submit transactions All nodes use Go Ethereum client (geth) client software Connect MetaMask to the load balancer in front of the transaction nodes to transfer Ether to and from blockchain
- 21. On Chain + Off Chain Architecture Client geth node Node.js Web Server Server 1 Client Mining geth node Server 2 MongoDB Basic Demo Architecture
- 22. Consuming Apps, Services & Systems Data Sources Apps Sensors Data Application InsightsAzure Key Vault Virtual NetworkingAzure AD API Ingestion Hub DLT Services (API, Hashing, Signing) Blockchain Ledger Off-Chain DB Off-Chain Storage Azure Functions Reference Data Power BI APIs Logic Apps Event Hub On Chain + Off Chain Architecture
- 24. Cryptlets Blockchains and smart contracts need a way to securely receive external data and access the execution of off-chain code. Cryptlets are off-chain code components that execute within a secure, isolated trusted container while maintaining the integrity of the blockchain. “Enterprise Smart Contracts” “Oracles”
- 25. Coco Framework Confidential consortium Foundation for protocols Launched Aug 17 Not for public blockchains Trusted Execution Environment - Speed + Scalability - Confidentiality - Governance
- 27. Take Aways 1. Before you do anything with blockchain – match your requirements with various ledgers and network types out there. 2. Microsoft’s blockchain strategy is that of building an enterprise grade environment which brings various blockchain initiatives closer to practical business scenarios. Templates on Azure + Coco Framework + Cryptlets
- 28. Johan Zammit j.zammit@smartstudios.io Take the leap. Deploy a blockchain on Azure.
Editor's Notes
- #9: https://www.bloomberg.com/news/articles/2016-05-22/fraud-in-4-trillion-trade-finance-turns-banks-to-digital-ledger https://www.bloomberg.com/news/articles/2016-05-22/stanchart-dbs-s-trade-finance-distributed-ledger-how-it-works At various points in the journey, the IoT device from the package sends the Temperature & Humidity data which are recorded on the blockchain
- #14: While we were working on our down digital transformation and doing all this extensive PoC work, we realized that Blockchain is definitely not a one-size-fits-all solution. Different customers require different ledgers for different purposes. Here at Microsoft, you can work with a number of great ledger technologies to ensure that, regardless of your use case, you can build on the right foundation. You can have a general-purpose ledger like Ethereum or Hyperledger Fabric, or you can have something more specialized like Corda or Chain, which both work really well in the financial services sector. We do this because our customers come to us all the time with different use-case-specific ledgers and we want to be ready to accommodate. We want to deliver the necessary tools to empower customers to get started on their own and experiment rapidly. That means being an open cloud platform for whichever ledger our customer wants to use. T: The Azure marketplace has become an open hub for developers to not only access tools and resources to accelerate blockchain evolution, but also contribute by publishing their own templates.
- #15: 2 years ago Microsoft came up with Project Bletchley and Blockchain as A Service.
- #23: A lot of times when people are developing blockchain solutions there's a bunch of scaffolding work that people have to go do. Scaffolding work here is connecting it to a lot of the middleware services that I just mentioned before. When we think about this, we've designed this app builder that sort of leverages this concept of some kind of ingestion hub like an event hub or a service bus, that's able to sort of be the entry point of information coming into the system. And the way we have it set up is the information comes into the ingestion hub and we have it syncing with the blockchain. So writing out transactions into the blockchain and then syncing that data back out to an off-chain data stores locations, so syncing your information to like a SQL database for example. And then at the same time being able to leverage integration points with other types of inputs, like IoT for example, with blockchain. So you have your sensor information coming in and participating in sort of your workflow and your blockchain network as well. And then once everything is into sort of an off-chain stores location you can imagine being able to easily pull that information out and start creating interesting analytics and machine learning based on the information that's being pushed into the system. T: So with that in mind I’m now going to show you guys a demo of a supply chain scenario.
