Unit 6 Q.1} What is hyperledger explorer? State its key features.                Hyperledger Explorer is an open source blockchain  utility module that allows users to create a user-friendly web-based application, with which a user can view, initiate, organize or query various artifacts and developments that form an integral part of the blockchain network.                Hyperledger Explorer is a tool for visualizing blockchain operations of the Hyperledger Fabric platform. It is the first ever blockchain explorer for permissioned ledgers, allowing anyone to explore the distributed ledger projects being created by Hyperledger’s members from the inside, without compromising their privacy. The project was contributed by DTCC, Intel, and IBM. The ability to visualize data is of critical importance, in order to extract business value from it. Hyperledger Explorer provides this much needed functi...

 Ethereum Q.1} State the different terms used in Ethereum statistics. Best Block is the heaviest block regarding the cummultative difficulty, or in simple words: the highest block number of the longest valid chain. Uncles are orphaned blocks, but in oposite to other blockchain systems, uncles are rewarded and included in the blockchain. Shows current bloc's uncle count and uncle count of last 50 blocks. Last Block shows the time since the last block was mined, usually in seconds. Average Block Time is, well, the average time between two blocks, excluding uncles, in seconds. Should be something around 15 seconds Average Network Hashrate is the number of hashes bruteforced by the network miners to find a new block. 5 TH/s means the network power is at five trillion hashes per second. Difficulty is the current mining difficulty to find a new block which basicly means how hard it is to find a matching hash. Active Nodes is the number of connected nodes to the Ethstats dashboard, (not ...

Unit 3   Q.1} Explain bitcoin wallet mining.                Bitcoin mining is done by specialized computers. The role of miners is to secure the network and to process every Bitcoin transaction. Miners achieve this by solving a computational problem which allows them to chain together blocks of transactions (hence Bitcoin’s famous “blockchain”). For this service, miners are rewarded with newly-created Bitcoins and transaction fees. Step #1:                 Get Bitcoin Wallet When earning bitcoins from mining, they go directly into a Bitcoin wallet. You can't mine without a wallet. Step #2:                  Find a Bitcoin Exchange When earning bitcoins from mining, you may need to sell the coins to pay for power costs. You may also need to buy coins on exchanges. Step #3:                  Ge...

 Unit 2 Q.1} What is digital token? State different types of digital tokens Digital Token                Digital tokens are either intrinsic or created by software and assigned a certain utility. Examples of intrinsic digital tokens are Bitcoin and Ether. The other type of digital token is asset-backed, which is issued to represent a claim on a redeemable asset such as legal tender or precious metals. Different types of digital token 1.Currency Token                Similar to how coins function, but more specific in their usage, payment tokens have the sole use of payment for services or goods. For example Bitcoin is a type of currency token meant to pay for goods and services. Bitcoin was, in fact, created to replace fiat (paper) money 2.Utility Token                Utility tokens are more than a means of payment. Specifically, they give users ...

Unit 1 Q.1 } What are the types of blockchain based on transfer capabilities and access capabilities? Explain with example. There are 3 type of blockchain 1.Public Blockchain               In a public blockchain a user can become a member of the blockchain network. This means they can store , send and receive data after downloading the required software on their device. Allowing anyone to read and write the data stored on the blockchain as it is accessible to everyone in the world.               A public blockchain is completely decentralised. The permissions to read and write data onto the blockchain are shred equally by all connected users, who come to a consensus before any data is stored on the database.               The most popular example of public blockchain is Bitcoin. the digital currency allows users to use a platform for making transaction directly between...

Distributed and Parallel Computing Q.1 } Explain Architectural styles of distributed System                There area four different architectural styles, plus the hybrid architecture, when it comes to distributed systems. The basic idea is to organize logically different components, and distribute those computer over the various machine. Layered Architecture Object Based Architecture Data - centered Architecture Event Based Architecture Hybrid Architecture 1. Layered Architecture                The layered architecture separates layers of components from each other, giving it a much more modular approach. A well known example for this is the OSI model that incorporates a layered architecture when interacting with each of the component . Each interaction is sequential where a layer will contact the adjacent layer and this process continues, until the request is been catered to....
