WO2015077378A1 - Block mining methods and apparatus - Google Patents

A blockchain, originally block chain, is a growing list of records, called blocks, that are linked using cryptography. What is the principle on which blockchain technology is based on? Ans: It enables the information to be distributed among the users without being copied. Ans: Blockchain can be trusted due to so many reasons. Its compatibility with other business applications due to its open-source nature.

Its security. As it was meant for online transactions, the developers have paid special attention to keeping up the pace when it comes to its security. Name the two types of records that are present in the blockchain database? Ans: These records are block records and transactional records. Both these records can easily be accessed, and the best thing is, it is possible to integrate them with each other without following the complex algorithms.

In Blockchain, blocks are linked in what series? Ans: In Blockchain Blocks are arranged within the Backward to the previous block series. How does a block is recognized in the Blockchain approach? Ans: Every block in this online ledger basically consists of a hash pointer which acts as a link to the block which is prior to it, transaction data and in fact a stamp of time.

Is it possible to modify the data once it is written in a block? In case any modification is required, the organization simply has to erase the information from all other blocks too. It is because of no other reason than this, data must be given the extreme care of while using this approach. Ans: In Blockchain, blocks can be identified by the block header hash and the block height.

Is it possible in Blockchain to remove one or more block from the networks? Ans: Yes, it can be done. There are times when only a specific portion of this online ledger is to be considered. With the help of default options and filters, this can easily be done without making a lot of efforts. What exactly do you know about the security of a block? Ans: Well, a block or the entire blockchain is protected by a strong cryptographic hash algorithm. Each block has a unique hash pointer.

Any modification in the block constituents will result in the change in the hash identifier of the block. Therefore, it offers an excellent level of security. Thus, one needs not to worry about the safety as well as the security of data that is present in a block. What is a ledger? Is Blockchain an incorruptible ledger? Ans: Blockchain is considered incorruptible. Any ill-intentioned individual acting alone is powerless. Should it happen, the individual would take every precaution to avoid being noticed.

How is a blockchain ledger different from an ordinary one? Ans: The first and in fact the prime difference is Blockchain is a digital ledger that can be decentralized very easily. The chances of error in this approach are far less than that in an ordinary ledger. An ordinary ledger is what that is prepared by hands or by human efforts while the Blockchain performs all its tasks automatically.

You just need to configure it in a proper manner and by following all the guidelines. What is the difference between Bitcoin blockchain and Ethereum blockchain? Ans: We can see the basic differences between Bitcoin blockchain and Ethereum blockchain in the below table.

A distributed digital ledger is used for recording transaction in Blockchain. What does the system rely on? Ans: The system relies on the network servicing protocol and the nodes of the network. Name some popular platforms for developing blockchain applications. Ans: After the development of bitcoin, various blockchain platforms started coming up.

Ethereum came right after the evolution of Bitcoins, and is one of the popular public platforms for building Blockchain based applications. Then there is a Hyperledger community for building enterprise-based solutions. What is Double Spending? Is it possible to double spend in a Blockchain system? It simply leads to inflation and organizations must bear a huge loss. One of the primary aims of Blockchain technology is to eliminate this approach up to the possible extent. Blockchain prevents double spending by confirming a transaction by multiple parties before the actual transaction is written to the ledger.

Each block of a Blockchain consists of which of the following? Which of the following is the first distributed blockchain implementation? Blockchain can be stored as which of the following? Ans: Backward to the previous block.

Hash identifying each block in the Blockchain is generated using which of the following cryptographic algorithms? A block in the blockchain can never have more than one parent block? Blockchain forks can result in which of the following? Which of the following is an asymmetric encryption Algorithm? Explain the significance of blind signature and how it is useful? Ans: It is a form of digital signature in which the content of a message is disguised blinded before it is signed. The resulting blind signature can be publicly verified against the original, unblinded message in the manner of a regular digital signature.

Blind signatures are typically employed in privacy-related protocols where the signer and message author are different parties. Examples include cryptographic election systems and digital cash schemes. What is Secret Sharing? Does it have any benefit in Blockchain technology? Ans: It is a well-known fact that security matters a lot in digital transactions.

Secret sharing is an approach meant for the same. In Blockchain technology it is an approach that divides secret or personal information into different units and sent them to the users on the network. The original information can only be combined when a participant to whom a share of the secret is allocated agrees to combine them together with others.

There are several security-related benefits it can offer in Blockchain technology. Can you explain what are off-chain transactions? Ans: An off-chain transaction is the movement of value outside of the blockchain. What exactly do you know about executive accounting? Does Blockchain support the same? Ans: Executive accounting is nothing but a special type of accounting which is designed exclusively for a business that offers services to the people.

There is no strict upper limit on services and a business can manage any through the executive accounting. Blockchain has algorithms that are specially meant to handle executive accounting. In fact, it cut down many problems that are associated with the same. What are the threats to the information you are familiar with? Ans: There are lots of threats to information in the present scenario. Due to increase in online transactions over the internet, many hackers have become active and are adopting new approaches to hack information and servers that contain financial information.

The major threat is software attack, identity theft, information extortion, as well as sabotage. In addition to this, Trojan horses, worms, and viruses are other trouble creators. How will you handle the risk management when it comes to securing the transactions records?

Ans: It is basically a process of finding the threats and all the vulnerabilities to the financial records of an organization. The best thing that can be done with this approach is to take the right countermeasures against them immediately. Another approach is to pay attention to a backup plan. Based on the value of information, more approaches such as buying new risk management software can simply be considered.

The prime risk to information is from black-hat hackers. It is Highly unlikely to be able to do that today but it is possible. What challenges information leak can impose on an organization? Ans: An information leak can cut down the reputation of an organization up to an excellent extent. In addition to this, it can be the reason for organizations bearing huge losses.

Many organizations who fail to implement security protocols to keep their data secure have already lost the trust of their customers and are struggling very hard to get the same reputation again. What is information processing according to you?

What are the key challenges that are associated with it? Ans: The information is often shared on a network.

What is timestamp server. We suggest you research available TSAs to find the best one for you. Timestamp servers cryptographically validate that a digital signature performing with a signing certificate took place at a specific time. My guess is that the log is updated after the transfer completes, with a timestamp for when it started, and probably by a different server thread.
