With reference to “Blockchain Technology” consider the following statements:
- It is a public ledger that everyone can inspect, but which no single user controls.
- The structure and design of blockchain is such that all the data in it are about cryptocurrency only
- Applications that depend on basic features of blockchain can be developed without anybody’s permission.
Which of the statements given above is/are correct?
Explanation:
- Statement 1 is correct: Blockchain technology is a structure that stores transactional records, also known as the block, of the public in several databases, known as the “chain,” in a network connected through peer-to-peer nodes. Typically, this storage is referred to as a ‘digital ledger.’ In simpler words, the digital ledger is like a Google spreadsheet shared among numerous computers in a network, in which, the transactional records are stored based on actual purchases. The fascinating angle is that anybody can see the data, but they can’t corrupt it.
- Statement 2 is incorrect: Blockchain is a shared, trusted, public ledger of transactions, that everyone can inspect but which no single user controls. Not all cryptocurrencies operate on a blockchain, and not all blockchains utilize cryptocurrencies as part of their design. Bitcoin relies on a public blockchain, a system of recording transactions that allows anyone to read or write transactions. Anyone can aggregate and publish those transactions. Moreover, Blockchain can be used for a variety of purposes of which cryptocurrency is only one of them.
- Statement 3 is correct: The great advantage to an open, permissionless, or public, blockchain network is that guarding against bad actors is not required and no access control is needed. This means that applications can be added to the network without the approval or trust of others, using the blockchain as a transport layer.
Hence option 4th is correct.

As an expert in information technology and blockchain technology, I can provide a detailed analysis of the concepts used in the provided article related to "Blockchain Technology" and the multiple-choice questions (MCQs) associated with it.
-
Blockchain Technology Overview:
- Blockchain is described as a public ledger that is open for inspection but not controlled by a single user.
- It stores transactional records (blocks) in a chain of databases through a peer-to-peer network.
- The digital ledger ensures transparency, and anyone can view the data without the ability to corrupt it.
-
MCQs Analysis:
-
Statement 1 (Correct): Blockchain is a public ledger where everyone can inspect transactions, and no single user controls it. This aligns with the basic principles of blockchain technology.
-
Statement 2 (Incorrect): The statement is incorrect as not all cryptocurrencies operate on a blockchain, and blockchain itself can be used for various purposes beyond cryptocurrencies. Bitcoin, however, relies on a public blockchain.
-
Statement 3 (Correct): Permissionless or public blockchains allow applications to be added without the need for approval or trust of others. Blockchain serves as a transport layer for various applications.
-
Explanation: The provided explanation correctly interprets each statement. It reinforces the fundamental characteristics of blockchain, its transparency, and its potential for various applications beyond cryptocurrencies.
-
-
Additional Information:
- The article refers to a link () for building a blockchain architecture, indicating a practical guide for implementing blockchain.
-
Conclusion:
- The article provides a comprehensive understanding of blockchain technology, covering its structure, transparency, and potential applications.
- The MCQs test the reader's knowledge of blockchain principles, and the explanations demonstrate a deep understanding of the technology.
For further details or specific questions about blockchain technology, feel free to ask.
