Blockchain Smart Contract Competency (Intermediate Level)

Topics covered

• access properties related to the next block to be added to the blockchain and the current transaction from within a smart contract
• build a smart contract and examine the outputs generated by the Solidity compiler
• connect the Remix IDE to the private Ganache network and deploy your smart contract to it
• create smart contracts with functions of varying visibility and recognize their access restrictions
• define a setter function to update the state variables of a smart contract
• demonstrate how to invoke a function to transmit Ether to a specified Ethereum account
• deploy a smart contract to the private network on Ganache via Metamask
• distinguish between while and do while loops
• invoke the selfdestruct function to remove the bank smart contract from the Ethereum network
• recognize the effect of using the "pure" access modifier for a function which does not access the contract state
• recognize the effects of provisioning variables in memory or storage during assignment operations
• use a struct to store and access composite data within one object
• use the deployed escrow smart contract to supply the required approvals for ether transfer and verify the behavior when the transfer is rejected
• use the selfdestruct function to delete a smart contract from the Ethereum network
• work with events and use them in smart contracts to log activities
