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 solidity is compiled then also Metadata is generated:
- A. the ABI array and the Metadata are not generated when solidity is compiled to bytecode, its generated by a migration software which deploys the smart contract on the blockchain.
- B. metadata contains the address, and the size of the smart contract. The ABI Array is generated externally upon deploying the smart contract.
- C. the Metadata contains the ABI Array, which defines the Interface to interact with the Smart Contract. Metadata can also contain the address of the smart contract when it gets deployed.
Correct Answer: C 🗳️
When defining a new datatype:
- A. it's best to use a struct, which is cheaper than deploying a new contract.
- B. its best to use a contract with public storage variables, so it can be used like a class.
- C. it's not possible to generate new datatypes in Solidity.

DApps are:
- A. a new way of applying logical operations for banks and big financial institutions. This way they can reduce the staff while operating at increased security.

- C. great, because they cut the middle man, run on a trusted platform, apply logic to the blockchain where already economic assets are running and thus allow peer to peer trade.
Correct Answer: B 🗳️
Proof of Work (PoW) vs. Proof of Stake.
- A. PoS is mining with specialized new hardware that has to be purchased with a stack of Ether in the network. Hence the Name: Proof of Stake, which derives from Stack.
- B. PoW is computationally intensive which requires lots of energy. On the other hand, miners earn straightforward a reward for mining a block and incorporating transactions.
- C. PoW is better than PoS, because with PoS we increase the amount of energy spent on the network.
