Skills: Implementing Business Network in Blockchain using HyperLedger Fabric

 BlockChain are centralized as well as decentralized as opposed to the popular belief that BlockChains are decentralized. Private or centralized BlockChain mechanism has restricted entry to make changes to the ledger whereas in public or decentralized BlockChain anybody can have access to the ledger(Bitcoin, Ripple etc.)

Merkle Tree is used to verify the transaction in the quickest time and less space complexity.

When a transaction occurs in a BlockChain the first step is to hash each transaction in the memory pool using SHA256.These hashes are then placed into a Merkle Tree (hash tree).The hashes of transactions are grouped into two and then concatenated result is hashed again until the tree is formed.

Hash at the top of the tree is called the Merkle root.The Merkle Root of this hash tree is placed into the block’s header along with the hash of the previous block and a random number called a nonce.The block’s header is then hashed with SHA256 producing an output that will serve as the block’s identifier.

 ECDSA is a cryptographic algorithm used by Bitcoin to ensure that the legitimacy of the transaction.It works on the principle of ECCDLP (elliptic curve cryptography discrete logarithmic problem) which means it is easy to go from A–>B but almost impossible to go from B–>A i.e ECC is a trapdoor function.

 ECC and RSA both algorithms work on the principle of asymmetric encryption.In asymmetric encryption, there is a public key for encryption and private key for decryption. ECC is better than RSA because it provides equivalent security for a much lesser key size which makes ECC faster and more secure.As for equal key size, ECC would be more secure than RSA.

A ledger is typically a database.The blockchain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the blockchain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender.

Ledgers can be centralized or decentralized depending on public or private BlockChain.

A distributed ledger is a database that is spread across several nodes or computing devices which are in layman terms the miners who run the algorithm on their computing devices. Every node copy and saves an identical copy of the ledger. Each participating node of the network updates itself independently.

The most striking feature of distributed ledger technology is that the ledger is not maintained by any central authority. Updates to the ledger are independent and done by each node. The nodes then vote on the update(transaction) to ensure that the majority agrees with the conclusion. This voting and agreement on one copy of the ledger is called consensus and is executed by a consensus algorithm.

BlockChains are only a form of distributed ledger technology. Every distributed ledger doesn’t use a chain of blocks to provide a secure and valid distributed confidence.

A BlockChain is distributed and is managed by peer-to-peer networks. Since it is a distributed ledger, it can exist without a centralized authority or server managing it, and its data quality can be maintained by database replication and computational trust.

The structure of the BlockChain makes it distinct from other kinds of distributed ledgers. Data on a BlockChain is grouped together and organized in blocks. The blocks are then linked to one another and secured using  ECC cryptography.

A quorum is the number of nodes required to reach agreement within a system. FBAs instead use ‘quorum slices’. A quorum slice is a subset of a quorum, which can convince another specific node to agree.

Segment Tree is a basically a binary tree used for storing the intervals or segments. The underlying principle behind this data structure is to store certain values of ranges as a balanced binary tree and hence query and update can be performed efficiently.

Diffie-Hellman is an algorithm used to exchange a secret key between two parties. It is used in symmetric encryption algorithms like AES.

Boxes are linked backward to the previous block in BlockChain.Genesis block is the first block of the BlockChain.A block can never have more than one parent block.
