Blockchain

Blockchain is an immutable, distributed public ledger and peer-to-peer (P2P network).

Features of Blockchain

SHA256 Hash Function: a one-way cryptographic function to generate a fixed size for any size of source text. The encrypted value cannot be decrypted back to the original text.
Public Key Cryptography: creating a set of keys referred as Public key and Private key.
Distributed Leger: a digital system in which transaction and their details are recorded in multiple places at the same time.
Peer to Peer Network: one in which two or more PCs shares files and access to devices such as printers without require a separate server computer.
Consensus Algorithm: a process in computer science used to achieve agreement on a single data value among distributed systems. Proof-of-Work is the original consensus algorithm in a Blockchain network.
Incentives for Validation: giving a reward for validating the transactions and maintaining the Blockchain

The two common types are the Public Blockchain and the Private Blockchain.

A public blockchain allows any node that has internet connection to access the blockchain by issuing either a write a read request. Some of the popular public blockchain available today are Bitcoins, Ethereum, Factom, Blockstream, and so on.
A private blockchain allows nodes to issue similar requests but these nodes must be predefined and authorized.
