# Blockchain Quick Overview

Blockchain Technology is also addressed as

* **The Next Stage of Internet**
    
* **The Trustless system of Values** (wherein TRUST is injected by crptography, game theory and other technologies; rather than human being)
    
* Technology quite *bigger and broader* than Bitcon
    

A Blockchain is

* A *Transparent*, Cryptographically *Trusted* Dapp/dApp (Decentralized application) system used for **management & exchange** of *Digital assets* like Ownership title, Medical Datasets, CryptoCurrency without the need of any external human/other wise driven system for TRUST.
    
* A **cryptographic database** maintained by a network of computers, each of which **stores a copy of the most up-to-date version of Ledger**. It uses *Blockchain Protocol* for TRUST in *Transaction and Ledger management*.
    
* A **Blockchain protocol** is a set of rules that dictate how the computers in the network, called nodes, should
    
    * *verify new transactions* and
        
    * *add them to the database*\*.
        
* The *Blockchain protocol* offers *Consensus building mechanism* by employing
    
    * **Cryptography**,
        
    * **Game theory**, and
        
    * **Economics**
        

to create incentives for the nodes to work toward securing the network instead of attacking it for personal gain.

* If the Blcokchain is set up correctly, this system can make it extremely difficult and expensive to add false transactions but relatively easy to verify valid ones.
    
* Blcokchain comes baked in with *Data Provenance* by offering
    
    * immutable and
        
    * cryptographically verifiable record of transactions
