Blockchain database tutorial

Now let's examine how blockchain functions like a database. Each node on the network maintains a copy of the data on the blockchain. For example, they all know how much money Alice has in her account. Instead of a bank storing all this data inside a central database, the blockchain stores it redundantly on each node in the network Intellipaat Blockchain course: https://intellipaat.com/blockchain-training-course/ This tutorial on Blockchain throws light on the database it uses to record..

What is Blockchain Database - Difference between

  1. Blockchain Definition. Blockchain can be defined as a continuously growing chain of blocks, which is a decentralized, distributed, and immutable database that records the derivations of digital assets. Every user of the network can reach consensus without trusting each other
  2. Blockchain is a shared database store continuously growing list of records, called blocks. Each block contains a hash of the previous block and a timestamp. In this tutorial, you will learn
  3. A Blockchain database consists of two kinds of records: blocks and transactions. Blocks hold batches of valid transactions that are hashed and encoded into a hash tree (a hash tree is a tree in which every leaf node is labeled with a data block, and every non-leaf node is labeled with the cryptographic hash of the labels of its child nodes)
