- It allows individuals and groups to work together without having to trust each other or establish authority. (Correct answer)
Correct answer: It allows individuals and groups to work together without having to trust each other or establish authority.
Blockchain is often called a 'trust layer' because its decentralized, immutable, and transparent nature allows parties to interact and transact without needing to trust a central authority or even each other. The cryptographic security and consensus mechanisms ensure that all transactions are verified and recorded accurately, creating a system where trust is built into the technology itself. This enables secure collaboration and value exchange in a trustless environment.
Question 7: What do you call the split in a blockchain?
- A division
- A merger
- A fork (Correct answer)
- None of above
Correct answer: A fork
A 'fork' in a blockchain refers to a divergence in the blockchain's history, typically occurring when there are changes to the protocol or when two miners find the next block at roughly the same time. This can result in two separate chains, either temporarily (soft fork) or permanently (hard fork), with different rules or transaction histories. Forks are a fundamental concept in blockchain evolution and governance.
Question 8: Blockchain is a particular kind of.......
- Database (Correct answer)
- Object
- Table
- View
Correct answer: Database
Blockchain is fundamentally a type of distributed database, but with unique characteristics. It stores data in chronological order in 'blocks' that are cryptographically linked together, forming an immutable chain. Unlike traditional databases, it is decentralized, meaning no single entity controls it, and its records are transparent and resistant to alteration.
Question 9: Data is stored in the form of on blockchains.
- Blocks (Correct answer)
- Circle
- lines
- None of above
Correct answer: Blocks
On blockchains, data is organized and stored in discrete units called 'blocks.' Each block contains a list of transactions, a timestamp, and a cryptographic hash of the previous block, linking them together in a continuous chain. This structure ensures the chronological order and integrity of the entire ledger, making it highly secure and immutable.
Question 10: In 2008,.................... created the blockchain.
- Satoshi Nakamoto (Correct answer)
- Bill Gates
- Alon Musk
- None of above
Correct answer: Satoshi Nakamoto
The concept of blockchain was first introduced in 2008 by an anonymous entity or group known as Satoshi Nakamoto. Nakamoto published a whitepaper titled 'Bitcoin: A Peer-to-Peer Electronic Cash System,' which detailed the design of Bitcoin and the underlying blockchain technology. This groundbreaking work laid the foundation for decentralized digital currencies and distributed ledger technology.
Question 11: The blockchain is regarded as a particular sort of.
- Payment Organisation
- Payment method
- Payment rail (Correct answer)
- None of above
Correct answer: Payment rail
Blockchain is regarded as a particular sort of 'payment rail' because it provides the underlying infrastructure and protocol for transferring value between parties. Similar to traditional payment rails like SWIFT or ACH, blockchain facilitates the movement of funds or assets. However, it does so in a decentralized, transparent, and often faster manner, bypassing traditional intermediaries.
Question 12: A hybrid blockchain combines a number of different features.
