Blockchain BTA Certified Blockchain Developer - Ethereum Sample Questions:
If you are starting a new ERC20 token:
- A. best is to start with an audited implementation, for example from OpenZeppelin, in order to reuse already existing code.
- B. it is beneficial to copy and paste the already existing code from the Ethereum wiki and modify this until you like it.
- C. it would be best to start from scratch, just looking at the required interface.
Correct Answer: A 🗳️
When considering smart contracts and the blockchain it's good:
- A. to move those parts to the blockchain that deal with Ether transfers. All other parts can remain in traditional database systems. This way only the value-transfer is on the blockchain.
- B. to move only those parts to the blockchain that really need the blockchain. This way smart contracts can be easier to read, easier to test and are not so complex.
- C. to move all existing logic to the blockchain, so everything runs on the same system. This way it might be more complex, but easier to maintain.
Correct Answer: B 🗳️
Why is Unit-Testing so important?
- A. It is a great way to spend time on something that you get paid for. But ultimately it will just slow down the development process.
- B. It helps you to find bugs, regression bugs and sometimes also helps you to understand your code from different angles.
Correct Answer: B 🗳️
Using truffle-contract over Web3.js:
- A. is a convenient way because Web3.js is currently still in beta and truffle-contract can handle transactions with JavaScript-promises.
- B. is a must for every developer, because Web3.js changes so often.
- C. they are both completely different things. Truffle-Contract is a framework while Web3.js is a library.
Correct Answer: A 🗳️
On a consortium network:
- A. everybody can become a miner, everybody can send transactions and everything is public.
- B. usually only a few selected nodes can be miners. Transactions can be further limited.
