Question:- Name some popular Blockchain Platforms for Blockchain Applications?
Answer:- The following is the list of widely-used platforms for blockchain-based applications • IBM Blockchain • EOS • OpenLedger • Corda • Ripple Blockchain • Ethereum Blockchain • IOTA • Quorum • OpenChain • Hyperledger Sawtooth
Question:- What is the difference between Blockchain and Hyperledger?
Answer:- • Blockchain is a technology that allows us to build decentralized systems. When we break down blockchain, the “block” refers to information stored in a digital format, while the “chain” refers to the database where that information is stored. • Hyperledger is a type of blockchain platform. It’s a blockchain-based open-source network. These blockchains each have their own storage routines and consensus, as well as smart contracts, identity, and access management. • Since hyperledger is a product of the blockchain platform, they have a few in common. However, due to hyperledger’s unique features, both are different. • Mostly, blockchain is classified into public and private types. And Hyperledger Blockchain is an example of a private blockchain.
Question:- What are some of the popular Cryptocurrencies?
Answer:- The most popular Cryptocurrencies are: Bitcoin(BTC) Ethereum(ETH) Ripple(XRP) Litecoin(LTC) Bitcoin Cash(BCH)
Question:- What is a ledger? What is the difference between a distributed ledger and a traditional ledger?
Answer:- A ledger is a constantly growing file. It maintains a permanent record of all transactions between two parties on the blockchain network. A distributed ledger is a database of digital data that is replicated, exchanged, and synchronized across multiple sites in a network. Distributed ledgers, unlike traditional ledgers (think banks, governments, and accountants), provide a system of synchronized databases that have an auditable background of information that is accessible to everyone inside the network.
Question:- What is a 51% Attack?
Answer:- A miner or a group of miners attempting to control more than 50% of a network’s hashing capacity, processing power, or hash rate is known as a 51 percent attack on a blockchain network. The attacker may prevent new transactions from taking place or being verified in this attack. They can also reverse transactions that have already been verified while in charge of the network, resulting in a double-spending problem.
Question:- What do you mean by blocks in Blockchain technology?
Answer:- In the Blockchain, a block is simply a set of records. The term “blockchain” refers to the process of joining these lists together. For example, if a company has 100 ledger books, the total is known as Blockchain, and each ledger is referred to as a block.
Question:- How does a block is recognized in the Blockchain approach?
Answer:- Any block in this online ledger consists primarily of a hash pointer that serves as a connection to the previous block, transaction data, and a time stamp.
Question:- Are there any network-specific conditions for using Blockchain technology in an organization?
Answer:- No, there isn’t any such restriction on using it. However, under the worried protocols, the network must be a peer-to-peer network. It effectively validates the new block and assists businesses in keeping up with the pace in this area without relying on third-party applications.
Question:- Is it possible to modify the data once it is written in a block?
Answer:- No, it is not possible to do that. If any customization is needed, the company simply needs to delete the details from all other blocks as well. Data must be treated with extreme caution when using this system for no other reason than this.
Question:- No, it is not possible to do that. If any customization is needed, the company simply needs to delete the details from all other blocks as well. Data must be treated with extreme caution when using this system for no other reason than this.
Answer:- In the Blockchain method, there are no limitations on the number of records that can be held. It is important to remember that record keeping is not limited to these applications. The following are examples of the types of information that can be held on them: 1. Health transaction records 2. Managing your identity 3. Production of transactions 4. Organizational events and management tasks 5. Documentation is required.
Question:- How Does Blockchain Create Blocks?
Answer:- When the block size is reached, the blockchain creates blocks automatically. Since the block is a file, the transactions are saved until the file is complete. They are linked in such a way that the most recent block is connected to the previous one. A hash value is created using a mathematical function to identify a block. It also shows any modifications made to a block.
Question:- Can Anyone Remove Blocks from A Blockchain?
Answer:- The manner in which blocks are removed from a blockchain is entirely dependent on how they are treated. Manually removing a block is not possible. If it is destroyed, however, the blockchain may attempt to restore the database using other peers. They can be removed after they’ve been checked to reduce the blockchain’s size since they don’t need someone to perform regular operations. It can be re-downloaded if necessary. This process is called pruning.
Question:- What is encryption? What is its role in Blockchain?
Answer:- Encryption is a technique that is used to keep the data secure. The data is encoded to some level before being sent out of a network by the sender in this process. Only the receiver will be able to decode it. This approach is useful in Blockchain because it simply adds to the overall protection and validity of blocks, making them more stable.
Question:- What exactly do you know about the security of a block?
Answer:- Any users on a network cannot customize a block. As a result, it offers a high degree of security. Furthermore, every block is protected by cryptography, which is yet another vote in this case. As a result, there is no need to be concerned about the protection of data in a block.
