What is TRUE about Go-Ethereum and Ganache

Ganache provides an in-memory blockchain simulation, whereas Go-Ethereum provides a genuine blockchain node that allows you to build your own local private network, connect to test networks, and access the main network.

With Ganache, you can connect to the Test-Networks Rinkeby and Ropsten using a genuine blockchain node.

Both are identical and are merely being expressed in different languages.

Correct! Wrong!

Which eth2 client does Chainsafe support?

Lodestar

Trinity

Lighthouse

Teku

Correct! Wrong!

Which is TRUE about Ethereum Nodes?

Must implement the Ethereum protocol, and only the exclusive Ethereum Libraries like Web3.js can be used for external access.

To connect with websites, you must use Web3.js.

Must implement a JSON-RPC for communication with clients and the Ethereum Protocol.

Correct! Wrong!

4) Which is TRUE about Block Timestamp?

The timestamp is always independent of the time zone, but it can be slightly modified by a miner.

The timestamp is widely regarded as secure to use for randomness on the blockchain because it cannot be tampered with by a miner.

Because the timestamp is based on the miner's time zone, the difficulty is constantly changing to account for network latency.

Correct! Wrong!

What is a Private Network?

A network that only operates in a private area, and prohibits public access

A virtual machine that may be launched in the Azure Cloud that is an exact replica of the Rinkeby Test-Network.

The Ethereum Main Net has a side channel that uses less gas to operate smart contracts.

Correct! Wrong!

What exactly are Ethereum Nodes?

A decentralized framework for deploying and managing smart contracts

A Java-Script library for assembling and executing Solidity Code

Software applications that use the Ethereum Protocol to communicate with one another and JSON-RPC interfaces to communicate with external systems.

Correct! Wrong!

Which is correct about Blockchain node?

May at any time turn into a mining node

Can become a mining node if the capability is included in the implementation.

Can never turn into a mining node.

Correct! Wrong!

Which is TRUE about Block Diffficulty?

The Block Difficulty rises when there are less than 10 seconds between mined blocks and falls when there are more than 20 seconds between mined blocks.

The Block Difficulty rises when there are fewer than 20 seconds between mined blocks and falls when there are more than 60 seconds between them.

The Ethereum Committee sets the Block Difficulty every two weeks to match the typical volume of transactions, and the network itself is unable to change it.

Correct! Wrong!

After a new block has been mined,

The block includes a list of the transactions and uncles. The balance of the miners is increased by the amount of gas spent during such transactions. Additionally, the miner receives the block reward. The network then achieves consensus by repeating the same transactions on all participating nodes.

That block includes a list of transactions. While the block reward is automatically distributed across the mining pool to ensure a fair distribution, the gas utilized during the execution is tied to the contracts that are actually being executed. By using a unique kind of hash code, consensus is achieved.

None of the above
