41. What is AVM?
• Algorand Virtual Machine
• The consensus network observes when a smart contract app
calls a transaction
• It sends it to the execution environment.
• The execution environment is commonly known as a virtual
machine
• It's a runtime within the consensus protocol.
• What does this mean?
• Smart contact program logic is executed and evaluated
• Either include that transaction in the next block
• Or discard it altogether if evaluation fails

42. Calls to get Address
• Java:
actual = Address.forApplication(appId);
• JavaScript
const actual = algosdk.getApplicationAddress(appID);
• Python
actual = logic.get_application_address(appID)
• Go
actual := GetApplicationAddress(appID)
