Question:- Why are SSL certificates used in Chef?
Answer:- SSL certificates are required between the client and the Chef server to ensure that the right data is accessible by each node. When an SSL certificate is sent to the server, the public key pair of each node is stored at the Chef server. The server then compares this against the public key for the identification of the node and gives it access to the required data.
Question:- How can Docker containers be shared with different nodes?
Answer:- Docker containers can be shared on different nodes with the help of the Docker Swarm. IT developers and administrators use this tool for the creation and management of a cluster of swarm nodes within the Docker platform. A swarm consists of a worker node and a manager node.
Question:- What is Blockchain technology?
Answer:- The blockchain is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value.
Question:- What is Blockchain Wallet and How Does It Work?
Answer:- A blockchain wallet is a piece of digital software that stores private and public keys, as well as tracks and records all transactions involving those keys on the blockchain. A blockchain wallet, in theory, does not store cryptocurrency; instead, all records belonging to these keys are stored on the blockchain on which the wallet is hosted. Blockchain wallets have public and private keys. A public key and a private key are used in a similar way in blockchain wallets. A public key is similar to an email address in that it can be shared with others. When your wallet is created, a public key is created as well, which you can share with others to obtain funds. The private key is a closely guarded secret. It’s similar to your password in that it shouldn’t be compromised, and you shouldn’t share it.

Answer:- Ethereum is an open-source software platform based on Blockchain technology that enables developers to build and deploy decentralized applications (i.e., applications that are not controlled by a single entity). You may construct a decentralized application in which the participants are the ones who make the decisions.
Question:- What is the difference between Bitcoin blockchain and Ethereum?
Answer:- Although bitcoin and ether are both digital currencies, the Ethereum blockchain differs significantly from the Bitcoin Blockchain. Bitcoin was created solely for the purpose of being a digital currency. whereas Ethereum blockchain is a broader version of blockchain technology. And it is a distributed ledger technology that organizations are using to create new services, however, Ethereum is much more stable than bitcoin.
Question:- What are Smart Contracts and how do they work?
Answer:- A smart contract is a computer code-based agreement between two individuals. They are stored on a public ledger and cannot be modified because they run on the blockchain. A smart contract’s transactions are handled by the blockchain, which means they can be submitted automatically without the involvement of a third party. The Smart contracts are secure, transparent, third-party-free, autonomous, and accurate. Let me use an example to demonstrate how smart contracts work. If Alex decides to sell his home to Bob. Then they would pay a slew of fees to third parties such as real estate agents, banks, attorneys, and others. However, with a smart contract, they can simply write a statement stating that if Bob pays this amount of money, he will be given ownership of the property. Hence, smart contracts can cut down the actual process and give us trustable options for transactions.
Question:- What Is Cryptocurrency Mining and how Bitcoin mining works?
Answer:- The word “crypto mining” refers to the process of obtaining cryptocurrencies by the use of computers to solve cryptographic equations. Validating data blocks and applying transaction records to a public record (ledger) is also a part of this method. Bitcoin mining is not just the process of putting new bitcoins into circulation, but it is also an important part of the blockchain ledger’s upkeep and growth. It is carried out with the assistance of highly advanced computers that solve extremely difficult computational math problems.
Question:- What is a Blockchain Explorer?
Answer:- A Blockchain Explorer is a piece of software that draws data from a blockchain using an API and a blockchain node, then uses a database to organize the data and present it to the user in a searchable format.
Question:- What Is Hashing in Blockchain?
Answer:- The process of making an input item of any length represents an output item of a fixed length is referred to as hashing in the blockchain. Take, for example, the use of blockchain in cryptocurrencies, where transactions of varying lengths are run through a given hashing algorithm and all produce a fixed-length performance.
Question:- What are the different types of Blockchain?
Answer:- The blockchain is classified into four types • Public Blockchains • Private Blockchains • Consortium Blockchains • Hybrid Blockchains.
Question:- What are the benefits of Blockchain Technology?
Answer:- Blockchain technology has the following benefits: • Blockchain technology employs advanced security compared to other networks or record-keeping systems. Prior to being recorded, all transactions must be agreed upon. A transaction is encrypted and connected to the previous transaction after it has been authorized. • Blockchain offers transparency. As one of the major problems in the new industry is transparency. An organization may use blockchain to create a completely decentralized network that eliminates the need for a centralized authority, increasing the system’s transparency. • Blockchain helps in reducing costs. Organizations will save a lot of money by using the blockchain instead of paying third-party vendors. • Blockchain automates time-consuming processes in order to increase performance. With the aid of automation, it also eliminates human errors. As a result, blockchain increases efficiency and speed. • The blockchain allows for immediate traceability. It generates an audit trail that records an asset’s provenance at each stage of its journey which prevents fraud.
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.
