Blockchain is a simple term in the world of cryptocurrency and the use of blockchain networks in crypto is very common, like an example on Crypto Shiba Inu which launches layer 2 solution blockchain named Shibarium.
In this article, we will give all the information about Blockchain technology in very simple words, What is Blockchain and how Blockchain technology works and what are the types of Blockchain and what are the advantages and disadvantages of Blockchain technology.
What is blockchain Technology?
Blockchain forms the foundation for digital currencies such as Bitcoin, operating as a decentralized ledger technology. It’s a growing collection of records, or blocks, interconnected through cryptography. Every block includes a cryptographic hash of the block before it, a timestamp, and transaction data. Once a block is added to the chain, it becomes unchangeable and requires network consensus to modify.
Decentralization is a fundamental aspect of blockchain technology. Unlike the conventional databases that reside on centralized servers, blockchain is spread out across a network of computers, or nodes. With no single point of failure, the system is extremely safe and resistant to hacking or data tampering.
Being transparent is a key feature of blockchain technology. Since the ledger is accessible to all participants in the network, transactions are permanently recorded and easily verifiable. Blockchain is a perfect fit for industries that value transparency and accountability, like finance, supply chain management, and healthcare.
Blockchain technology also allows for smart contracts, which are contracts that self-execute based on code. These contracts automatically trigger upon meeting specific requirements, removing the necessity for middlemen and lowering the chances of fraud.
Overall, blockchain could completely transform how transactions are carried out and information is exchanged. The decentralized and transparent nature provides a secure and efficient method for conducting business, leading to its growing popularity across different industries.
How does blockchain technology works?
Blockchain technology creates a secure and decentralized digital ledger which records transactions in the computers of a network. A blockchain network is a place where each transaction is recorded, and verified by a variety of participants (known by the name of nodes) within the network.
When a transaction is confirmed then it is incorporated into the block of transactions which is later linked to the prior block of transactions in chronological order, which is why it’s the term “blockchain.”
The main advantages of blockchain technology are transparency security, security, immutability and decentralization. Blockchain transactions are accessible to anyone within the network, making it an open system.
The security of blockchain is due to using cryptographic algorithm that protect the information and prevent tampering or unauthorised access. When a transaction is included in the blockchain it can’t be edited or erased, which ensures the integrity of the blockchain.
Decentralization is an essential aspect of blockchain technology because there isn’t a central authority to oversee the network. Instead the network is managed and protected by everyone within the network, which makes it invulnerable to censorship and manipulation.
This implies that there isn’t a single point of failure on the blockchain network, which makes it highly secure and reliable method of keeping track of transactions and recording them.
How many types of blockchain?
Blockchain technology has been rapidly evolving over the past decade and has given rise to various types of blockchain networks. In this article, we will discuss four main types of blockchain – public blockchain, private blockchain, consortium blockchain, and hybrid blockchain.
1. Public blockchain:
Public blockchain is a decentralized network where anyone can participate in, view, or validate transactions. It is an open and permissionless system that allows anyone to become a node in the network.
One of the key features of a public blockchain is transparency, as all transactions are publicly viewable and cannot be changed once they are added to the chain. Bitcoin and Ethereum are popular examples of public blockchains that are used for cryptocurrency transactions, smart contracts, and other decentralized applications.
2. Private blockchain:
Private blockchain, also known as permissioned blockchain, is a closed network where access and participation is restricted to a specific group of users. In a private blockchain, permission to join the network, validating transactions, and accessing data is controlled by a central entity or group of trusted nodes.
This type of blockchain is often used by enterprises and organizations that need greater control over their network and data privacy. Private blockchains are faster, more efficient, and have higher scalability than public blockchains.
3. Consortium blockchain:
Consortium blockchain is a combination of public and private blockchains, where a group of organizations come together to form a network and share authority over the blockchain. In a consortium blockchain, the participants are known entities that operate and validate the network, but the network is not completely decentralized like a public blockchain.
This type of blockchain is suitable for industries that require collaboration between multiple stakeholders, such as supply chain management, healthcare or finance. Consortium blockchains provide improved efficiency, security, and trust between participating organizations.
4. Hybrid blockchain:
Hybrid blockchains combine the features of both public and private blockchains, providing a flexible and customizable solution for different use cases. In hybrid blockchains, some parts of the network are public and decentralized, while other parts are private and permissioned.
This allows organizations to take advantage of the benefits of public blockchains such as transparency and security while maintaining control over sensitive data and operations. Hybrid blockchains are increasingly being used in areas such as healthcare, voting systems, and identity management.
Finally, blockchain technology is constantly evolving and offering innovative solutions to various industries. Understanding the different types of blockchain networks can help organizations choose the right platform that meets their specific needs and requirements.
Be it public, private, consortium or hybrid blockchain, each type has its own unique advantages and applications in the changing digital landscape.
