There are now four different kinds of blockchain networks. These are _______ .

Correct! Wrong!

There are four main types of blockchain networks:
Public Blockchains: These are open and decentralized networks where anyone can participate and view transactions. They are often permissionless and provide high decentralization.
Private Blockchains: Private blockchains are controlled by a single entity or a select group. They are used for internal purposes, offering more control but sacrificing some decentralization.
Consortium Blockchains: Consortium blockchains are operated by a group of organizations with shared interests. They strike a balance between decentralization and control.
Hybrid Blockchains: Hybrid blockchains combine features of both public and private blockchains, aiming to achieve a flexible balance between decentralization and control.
Each type has its own strengths and weaknesses, making them suitable for various use cases depending on the specific requirements of the application.

The blockchain is regarded as a particular sort of.

Correct! Wrong!

The blockchain is not typically regarded as a "payment rail." A payment rail refers to a specific method or system for transmitting payments between individuals, businesses, or entities. Examples of payment rails include credit card networks, bank transfers, and payment processors like PayPal.

What advantages can blockchain technology provide the insurance sector?

Correct! Wrong!

Insurance firms may now add more value to their existing relationships thanks to blockchain technology.

How can blockchain technology support the preservation of IP?

Correct! Wrong!

IP is based on the idea of fairness, "who did what when," and the idea that the first person to take action should be entitled to the financial reward for their actions. It is feasible to prove that something existed at a specific time using blockchain, and third parties can confirm that information.

Blockchain is a particular kind of.......

Correct! Wrong!

A blockchain is a particular kind of database. It's a distributed and decentralized digital ledger that stores data in a series of blocks, where each block contains a set of transactions or information. These blocks are linked together using cryptographic hashes, creating a chronological and tamper-resistant chain of data. This structure provides transparency, security, and immutability, making it suitable for various applications beyond just cryptocurrencies, such as supply chain management, voting systems, and more.

Which government is aggressively supporting the usage of blockchain, for instance?

Correct! Wrong!

The MAS is using DLT to create central bank digital currency. In the project's initial phase, which began in 2016, they demonstrated how to carry out a domestic inter-bank transaction using a central bank-issued token with an equivalent value to the Singapore Dollar (SGD).

Some of the biggest and best-known public blockchains include the __________ .

Correct! Wrong!

These two blockchains have a significant impact on the blockchain and cryptocurrency space, with Bitcoin pioneering the concept of a digital currency and Ethereum introducing programmable blockchain capabilities.

Who is a blockchain miner?

Correct! Wrong!

Blockchain miners are individuals or entities that use computational power to validate, process, and add transactions to a blockchain. They play a crucial role in maintaining the security and integrity of the blockchain network by ensuring that transactions are legitimate and following the consensus rules.

In 2008,.................... created the blockchain.

Correct! Wrong!

In 2008, Satoshi Nakamoto is credited with creating the blockchain. He (or she, or they) is the pseudonymous individual or group behind the creation of Bitcoin, the first cryptocurrency, and its underlying technology, which includes the concept of the blockchain. Satoshi Nakamoto's whitepaper titled "Bitcoin: A Peer-to-Peer Electronic Cash System" was published in October 2008, outlining the principles of a decentralized digital currency and the innovative blockchain technology that supports it.

A hybrid blockchain combines a number of different features.

Correct! Wrong!

A hybrid blockchain combines features of both centralized and decentralized systems. In a hybrid blockchain, certain elements of the network are controlled by a centralized entity, while other aspects remain decentralized. This approach allows organizations to find a balance between the benefits of decentralization, like transparency and security, and the control that centralized systems can offer.

Which blockchain claim is accurate?

Correct! Wrong!

All three statements are true about blockchain:
Blockchain has been described as a value-exchange protocol: Blockchain technology enables the exchange of value, often in the form of cryptocurrencies, through secure and transparent transactions.
Blockchain database is managed autonomously using a peer-to-peer network: Blockchain operates on a network of nodes (computers) that work together to maintain and validate the database without the need for a central authority.
Blockchain is a decentralized, distributed, and oftentimes public, digital ledger: Blockchain is decentralized because it lacks a central control point, distributed because multiple copies of the ledger are maintained across the network, and it's often public, meaning that anyone can access and participate in the network.

What did they accomplish jointly?

Correct! Wrong!

The first interbank transactions using blockchain technology were carried out in 2016 by The Monetary Authority of Singapore in collaboration with the blockchain firm R3. The project demonstrated that banks were no longer constrained by time zones and office hours and could transact and settle at any time.

Data is stored in the form of on blockchains.

Correct! Wrong!

Data is stored in the form of blocks on a blockchain. Each block contains a collection of transactions or information that is added to the blockchain's chain in a sequential order. These blocks are linked together using cryptographic hashes, forming a secure and tamper-resistant record of data. The data within a block can vary depending on the type of blockchain and its specific use case, but it typically includes information about transactions, timestamps, and references to the previous block's hash.

What exactly is digital fiat money?

Correct! Wrong!

Digital fiat money, which is issued and governed by the nation's competent monetary authority, is described as the representation of a particular nation's currency in a digital format.

What do you call the split in a blockchain?

Correct! Wrong!

The term for when a blockchain splits into two separate chains due to a divergence in consensus rules or protocol changes is called a "fork." There are two main types of forks: hard forks and soft forks.

Why is blockchain referred to as the technology that gives the internet an extra layer of trust?

Correct! Wrong!

It makes it possible for people, organizations, and governments to collaborate in a fair and transparent way without previously establishing trust, ownership, or authority.
