Blockchain and the blockchain - lesson 1&2

What was the primary motivation behind the creation of the EOS blockchain?

• To increase the decentralization of blockchain networks

• To provide a more user-friendly interface for cryptocurrency wallets

• To overcome the limitations of transaction speed and costs in existing blockchains

• To create a blockchain specifically designed for virtual item trading

How does the DPoS (Delegated Proof of Stake) consensus mechanism used by EOS differ from the mining process in Bitcoin and Ethereum?

• DPoS allows for faster transaction validation through elected validators

• DPoS requires users to stake their tokens to participate in the consensus

• DPoS is more energy-efficient than traditional mining

• All of the above

According to the passage, what is the main drawback of the "scatter" wallet mentioned for the EOS platform?

• It has high transaction fees

• It is not compatible with the EOS network

• It is too complicated for the average user to use

• It is not secure enough for storing EOS tokens

Which of the following statements best summarizes the key advantage of the EOS platform over Ethereum, as discussed in the passage?

• EOS has a higher transaction throughput capacity

• EOS has lower transaction costs for users

• EOS has a more decentralized network structure

• EOS has a larger number of dApps built on its platform

What is the primary purpose of the "staking" feature mentioned in the context of the EOS blockchain?

• To earn rewards for holding EOS tokens

• To reserve system resources on the EOS network

• To participate in the DPoS consensus mechanism

• Both B and C

How does the "wax protocol" mentioned at the end of the passage aim to address the issues faced by the EOS platform?

• By improving the scalability and usability of the EOS network

• By creating a new blockchain specifically designed for virtual item trading

• By providing a better user interface for creating and managing blockchain accounts

• All of the above

Based on the information provided in the passage, which of the following can be considered a potential limitation of the EOS platform?

• Lack of decentralization

• Slow transaction speed

• High transaction costs

• Complicated user onboarding process

According to the text, what is the primary purpose of using a distributed ledger technology?

• To increase transparency and accountability in record-keeping.

• To replace traditional banking and financial systems.

• To provide a secure and immutable storage for cryptocurrency.

• To reduce the risk of hacking and data manipulation.

The text states that distributed ledgers are "immutable," meaning that once data is added, it cannot be deleted. What is the main benefit of this feature?

• It prevents unauthorized changes to the ledger.

• It ensures the chronological order of transactions.

• It enhances the overall security of the network.

• It makes the ledger more transparent and accessible.

The text compares a distributed ledger to a traditional ledger controlled by a single entity. What is one potential drawback of a traditional ledger mentioned in the passage?

• It is more vulnerable to hacking and data breaches.

• It lacks transparency and public accessibility.

• It is less efficient and slower in processing transactions.

• It is more prone to human error and internal manipulation.
