Types of Blockchains – Explained

There are many types of blockchains, each with its own unique characteristics. Each type of blockchain has its own advantages and disadvantages. Here’s a quick rundown of the most popular blockchain types:

  • Permission-less or Public Blockchains: A public blockchain is a decentralized network that anyone can join and participate in. Bitcoin and Ethereum are examples of public blockchains.
  • Permissioned or Private Blockchains: A private blockchain is a network that is restricted to only certain users. A company or organization may create a private blockchain for internal use.
  • Federated or Consortium Blockchains: A consortium blockchain is a semi-decentralized network that is governed by a group of organizations. R3 Corda is an example of a consortium blockchain.
  • Hybrid Blockchains: A hybrid blockchain is a network that combines the features of both public and private blockchains. Dragonchain is an example of a hybrid blockchain.
  • Sidechains: A sidechain is a blockchain that runs in parallel to another blockchain. It is used to extend the functionality of a main blockchain. The Liquid Network by Blockstream is an example of a sidechain.

Benefits of Blockchains:

Blockchains have many potential benefits, including:

  • Decentralization: Blockchains are decentralized networks, which means there is no central authority or middleman. This allows for more peer-to-peer transactions and reduces the need for intermediaries.
  • Immutability: Once data is stored on a blockchain, it cannot be changed or deleted. This makes blockchains ideal for storing immutable data, such as financial transactions.
  • Transparency: Blockchains are transparent networks, which means all transactions are public and anyone can view them. This can help to increase transparency and trust in a system.
  • Security: Blockchains are secure networks, thanks to their decentralized nature and cryptographic hashing. This makes them ideal for storing sensitive data.
  • Speed: Blockchains can help to speed up transactions, due to their decentralized nature and lack of intermediaries.
  • Scalability: Blockchains are scalable networks, which means they can handle a large number of transactions. This is thanks to their distributed ledger technology.

Which type of blockchain is right for your project?

The answer to this question depends on your project’s needs. If you need a blockchain that is secure and immutable, then a public blockchain like Bitcoin or Ethereum may be a good choice. If you need a blockchain that is scalable and fast, then a sidechain or hybrid blockchain may be a better option.
