There are four different types of blockchain - Public blockchain, Private blockchain, Consortium blockchain and Hybrid blockchain. This presentation gives a glimpse about blockchain technology and the different types of blockchain. Hope it helps!

1. Types of Blockchain

2. Introduction
• A blockchain is a distributed software network that functions
both as a digital ledger and a mechanism enabling the secure
transfer of assets without an intermediary.
• Just as the internet is a technology that facilitates the digital
flow of information, blockchain is a technology that facilitates
the digital exchange of units of value.
• Anything from currencies to land titles to votes can be
tokenized, stored, and exchanged on a blockchain network.

3. Types of Blockchain
There are 4 types of blockchain – Public blockchain, Private blockchain,
Hybrid Blockchain and Consortium Blockchain

4. Public Blockchain
• A public blockchain is a non-restrictive, permission-less distributed
ledger system.
• Anyone who has access to the internet can sign in on a blockchain
platform to become an authorized node and be a part of the
blockchain network.
• Examples – bitcoin, litecoin
Advantages:
1. Trustable
2. Secure
3. Open and Transparent

5. Private Blockchain
• A private blockchain is a restrictive or permission blockchain operative
only in a closed network.
• Private blockchains are usually used within an organization or
enterprises where only selected members are participants of a
blockchain network.
• Examples – Multichain and Hyperledger projects
Advantages:
1. Speed
2. Scalablity

6. Consortium Blockchain
• Consortium blockchain is a semi-decentralized type where more than
one organization manages a blockchain network.
• This is contrary to what we saw in a private blockchain, which is
managed by only a single organization.
• Examples – Energy Web Foundation, R3
Advantages:
1. Improve workflows
2. Accountability
3. transparency

7. Hybrid Blockchain
• A hybrid blockchain is a combination of the private and public
blockchain.
• It uses the features of both types of blockchains that is one can have a
private permission-based system as well as a public permission-less
system.
• Example – Dragonchain
Advantages:
1. Secure
2. Speed

8. Which one is better?
• We have understood two main types of blockchains i.e. private and
public blockchains.
• Both have certain distinctions from one another.
• However, the main differences lie in terms of security, scalability, and
transparency.
• On one hand, where a private network might not seem very
trustworthy, you can completely rely on a public network for its intact
consensus (proof-of-work) system.
