Transcript

1. Lightweight Smart Contract in Java Blockchain as a Service (BaaS)
2. Overview Part I Elements of Blockchain Smart Contracts Solution Part II Ardor Lightweight Contracts Development Tools and Environment Configuration, Deployment and Execution
3. What is a Blockchain? An immutable evidence trail
4. Blockchain is an immutable decentralized ledger where records are replicated on every computer that maintains a consistent state through a consensus algorithm.
5. Blockchain Elements - Actions (e.g. Transactions) - Blocks - Wallets (Accounts) - Mining/Forging (consensus)
6. A contract is a legal document between parties that spells out what is required of each party. What is a Contract?
7. Business Logic Programmability and Intelligence to the Blockchain What is a Smart Contract?
8. “A smart contract is a set of promises specified in digital form including protocols with which the parties perform on these promises.” — Nick Szabo, 1996
9. • Stores Rules • Verifies Rules • Executes the Rules Smart Contract allows for real world constrains to be realized in transfer of values.
10. Account Management Asset Management Identity Management Record Management etc etc Smart Contract Solutions
11. Voting Education Agriculture IoT (e.g. Smart Property) Insurance, Banking and Finance etc etc Use Cases
12. Contract Setup Parameters are configured Codes are Deployed & Stored as cloud data Contracts are associated with a contract reference Txn Ardor Lightweight Contracts
13. Automatic Message Manual Message {“contract”:“HelloWorld” } Contract Account Ardor Account 2
14. Ardor Client 2.2.2 IntelliJ (2018.3) Java (JDK 8) Development Tools and Enironments
15. 1. Install Java JDK and Ardor Client 2. Contract Configurations 3. Setup Development Environment 4. Contract Development 5. Contract Deployment (using Contract Manager Plug-in) 6. Contract Trigger Transaction Lightweight Contract Framework
16. Go to jelurida.com to download the Ardor Client
17. The Ardor Client Setup a minimum of Two Accounts

27. 1. 2 key components: • Contract Runner • Contract Manager 2. Open Ardor Installation folder and open conf. folder 3. Create a new file named nxt.properties Contract Configurations
28. nxt.properties File Contract Runner nxt.addOns = nxt.addons.ContractRunner addons.contractRunner.secretPhrase = [ ] addons.contractRunner.feeRateNQTPerFXT = 100000000 Contract Manager contract.manager.serverAddress = localhost contract.manager.userHttps = false contract.manager.secretPhrase = [ ]
29. File: nxt.properties
30. Sample Contract Development: HelloWorld
31. Contract Deployment: -> File -> settings -> Plug-ins -> Contract Manager
32. Cogwheel Menu -> Install Plug-ins form disk -> ContractManagerPlugin.zip file Restart IntelliJ IDE
33. ARDOR Start and Stop the Ardor Server
34. Edit Configuration to add Ardor Contract Manager Configuration
35. Ardor Contract Manager
36. Change Name to HelloWorld Change Contract Class to HelloWold
37. Run Configuration to deploy Contract HelloWorld Configuration
38. Contract Trigger: {“contract”:”HelloWorld”}
39. ARDOR Successfully Deployed and Invoked
