Blockchain networks types

There are three types of blockchain network types.

Private: HyperEdge: Private blockchains are the property of an individual or a company.
Public: Ethereum Public blockchains are for everyone i.e. public. Anyone can read and write operations on it.
Consortium or Federated Blockchain: R3 It is a hybrid blockchain , manged by a group of companies. Multiple persons or entities manage the blockchain.

What is the difference between a database and a blockchain ledger

Database	Blockchain ledger
Database is a controlled and centralized storage mechanism	Ledger is a decentralized storage mechanism
Admin or users has a control mechanism	Anyone can join and gives control
Read and writes are happening based on permissions	data process done with Right proof of work permissions
Performance is fast and good	Performance is slow

What are examples of blockchain?

Blockchain is a new technology used in many types of domains.

Popular blockchain example applications are Bitcoin, cryptocurrencies, and Ethereum.
