1. Introduction to Blockchain App

1.1. What is Blockchain?

A blockchain is a distributed database that maintains a continuously growing list of ordered records, called blocks. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data.

The blocks are linked together using cryptography, and each block can only be changed if all subsequent blocks are also changed. This makes it very difficult to change or hack the data in a blockchain.

1.2. What is Blockchain App Development?

Blockchain app development is the process of creating applications that use blockchain technology. Blockchain apps are typically decentralised, for that reason, they do not rely on a central authority to operate. This makes them more secure and transparent than traditional applications.

Here is how a blockchain app works:

  • A user initiates a transaction
  • The transaction is broadcast to the blockchain network
  • The nodes in the blockchain network verify the transaction
  • If the transaction is verified, it is added to a block 
  • The block is added to the blockchain
  • The transaction is completed

When adding the transaction to the blockchain, you cannot change or delete it. As a result, this makes blockchain apps very secure and reliable.

1.3. Types of Blockchain Apps

There are many different types of blockchain apps, each with its own unique purpose. Here are some of the most common types:

Financial apps

These apps use blockchain to facilitate financial transactions, such as payments, trading, and lending. Some popular examples of financial blockchain apps include Bitcoin, Ethereum, and Ripple.

Supply chain management apps

These apps use blockchain to track the movement of goods and materials through a supply chain. This can help to improve transparency and efficiency. For example, some popular supply chain management blockchain apps include IBM Food Trust and TradeLens.

Healthcare apps

These apps use blockchain to store and share medical records and other sensitive data. This can obviously help to improve security and privacy. Some popular examples of healthcare blockchain apps include MedRec and Patientory.

Intellectual property apps

These apps use blockchain to register and track intellectual property, such as patents and copyrights. This can help to prevent counterfeiting and fraud. Some popular examples of intellectual property blockchain apps include Everledger andProvenance.

Voting apps
