Types Of Blockchain

Blockchain technology has been around for decades, but only recently has it become popularized. The technology behind Bitcoin and other cryptocurrencies is now being used in many different industries, including healthcare. Blockchain allows users to maintain anonymous and secure data transmission through public key encryption, which provides users with a public key to receive transactions and a private key to send them. Blockchain technology, a distributed ledger that records and verifies every transaction, can be an effective tool for governments and institutions to secure transactions, automate processes, and build public trust.

Here's what you need to know about each type: 

These are the main types of blockchain: public, private, consortium and hybrid.

Public blockchains are open networks where anyone can participate.

Private blockchains are closed networks with permissioned participants.

Consortium blockchains are hybrid models that combine elements of both public and private blockchains. 

Public Blockchain Or Permissionless Blockchain:

In a public blockchain architecture, you can download the protocol at any time, and the blockchain is permissionless, which means you don't need any permission from anyone to enter and interact with the network; anyone can read, write or participate in the blockchain. A public blockchain is one that everyone in the world can view, submit transactions and expect those transactions to be enabled if they are valid and participate in a consensus process that determines which blocks are added to the chain and what the current status is. Since anyone from anywhere in the world can become a node, verify other nodes, and trade bitcoin, this form of blockchain network is a public network.

Private Blockchain Or Permissioned Blockchain:

A private blockchain is used by a group of people who share a common interest. They use the blockchain to keep track of transactions among themselves. Authorized blockchains restrict access to the blockchain network to certain nodes, and can also limit the permissions of those nodes in the network.

The speed of private blockchains makes them ideal for situations where the blockchain needs to be cryptographically secure but regulators do not want the public to have access to information and information that needs to be cryptographically secure but not open to the public (such as census health records) and companies that utilize blockchain technology without exposing their trade choice secret to the public and competitors. Private blockchains are also centralized in nature, meaning that companies can control the network without opening it to the public.

Consortium Blockchain:

In a consortium blockchain, some aspects of an organization are public, while others remain private. Private and consortium blockchains are commonly used by businesses seeking to use blockchain architecture but want to ensure that specific information remains private for regulatory or competitive reasons. It is different in that it involves different members of an organization working together in a decentralized network. Consortium blockchains are distributed ledgers controlled by multiple entities, each of which controls a network node, participates in consensus, and has rights to view certain types of data.

Hybrid Blockchain:

Businesses can use a hybrid blockchain to operate systems privately but show certain information, such as advertisements, to the public. In private data chains, data is closed to the public, but in hybrid data chains, the organization can decide what data is public and control who can access the data. Members of the hybrid blockchain can choose the members of the blockchain or decide which transactions can be made public.

As a rule, transactions and records in the hybrid block chain are not published, but if necessary, they can be verified, for example, by granting access through a smart contract. Hybrid blockchain allows for private but verifiable transactions that an organization cannot change. The biggest advantage of a hybrid blockchain is that it runs in a closed system. It uses the properties of both blockchains, allowing you to have a permission-based private system and a permission-free public system.

Which one is better:

Within these boundaries, private and public blockchains differ in scalability, transaction speed, openness, and security. The main difference between public and private blockchains is who can join the network, run consensus protocols that determine mining rights and rewards, and maintain a shared ledger.
