  1. We us truffle console when we already have an ethereum client, we want to migrate our contract to the mainnet or testnet or when we have to use specific account list.
  2. So that we can easily deploy our smart contracts easily.
  3. A list of accounts, their private keys and the mnemonic phrase.
  4. It runs migartion files to deploy contracts.

1. What is the difference between Truffle Console and Truffle Develop?
Console accesses existing clients or you are working with real-world external systems and data.
Develop is a way in which to do the same actions though in a sandbox type environment.

2. Why is it important to know how to use them?
Because they each have their own use cases and are valuable in those different domains.

3. What is printed in the console when launching Truffle Develop?
This shows you the addresses, private keys, and mnemonic for this particular blockchain.

4. What does the migrate command do?
This allows the contract to be deployed to a testnet or the Ethereum mainnet.

  1. The Truffle Console provides basic interactive console access to any Ethereum client. Truffle Develop provides the console as well as a local development blockchain to test contracts.

  2. Truffle Console and Develop allow you to stand up a quick local blockchain instance to quickly test projects. The Truffle Console also allows you to connect to other Ethereum clients like Ganache (I like this method) as well as enabling contract migrations to the testnet. If you want to quickly test a contract it’s quick with Truffle Develop, however if you want to develop a more complex dapp and simulate real world, you would use the Truffle Console connected to an Ethereum client like Ganache and metamask for testing and then you could migrate locally tested contracts to testnet…

  3. The default connection for the Truffle Console is development. Unless you override to connect to local Ganache, Geth or testnet, the console will display “truffle(development)” to indicate you are connected to local Truffle Develop environment.

  4. The migrate command deploys the configured contracts to the network the console is connected to. Once deployed, you can use the Truffle Console to interact with the contracts.

  1. What is the difference between Truffle Console and Truffle Develop?
    Console enables you to connect to any Ethereum network while Develop provides an isolated local network to test your contract.
  2. Why is it important to know how to use them?
    They are tools the make it easy for you to test, deploy and interact with your contract before spending the time and money to deploy to the production network.
  3. What is printed in the console when launching Truffle Develop?
    The command is truffle develop. When it spins up the URL of the node, a list of test account address are displayed (first public keys then secret keys) and finaly the menomic of the node is displayed.
  4. What does the migrate command do?
    Truffle migrate will deploy all compiled contracts in your project (based on the scripts in the migrations folder) are deployed to the target network.

  1. What is the difference between Truffle Console and Truffle Develop?
    The console will let you interact with any ethereum client and the develop also lets you access a development blockchain locally.

  2. Why is it important to know how to use them?
    It will help you with testing the contracts you make on a local blockchain without having to deploy them on testnet or mainnet

  3. What is printed in the console when launching Truffle Develop?
    The addresses you can use + private keys that belongs to there addresses + mnemonic words

  4. What does the migrate command do?
    I launches the last version (highest migration nr) of the contract on the blockchain.

1. What is the difference between Truffle Console and Truffle Develop?
The console connects to an existing client. Develop creates it’s own development blockchain.

2. Why is it important to know how to use them?
It will be helpful for development and testing of smart contracts. You can use develop to test contracts on your own blockchain without having to use the testnet or mainnet.

3. What is printed in the console when launching Truffle Develop?
The addresses, private keys and mnemonic words for the account

4. What does the migrate command do?
It deploys all of the compiled contracts on the blockchain you are connected to
