Public blockchain networks
A public blockchain network is a decentralized network that is open for anyone to join and participate. In a public blockchain, anyone can read, write, and audit the transaction history, and all participants have equal power and authority within the network.
Some examples of public blockchain networks are the Bitcoin and Ethereum networks.
Private blockchain networks
In a private blockchain, only authorized users can join and participate in the network, and access to the transaction history may be restricted to certain users.
Private blockchains are often used by organizations that want to utilize blockchain technology's benefits, such as increased transparency and security while retaining control over network access and the data within it.
Permissioned blockchain networks
A permissioned blockchain network is a type of private blockchain network that requires participants to obtain permission to join and access the network. Access is usually limited to a particular group of individuals or organizations, and participants must be authorized by a central authority or a group of authorized users before they can join the network.
A consortium blockchain network is a type of private blockchain network owned and operated by a group of organizations, rather than a single entity.
Compared to public blockchain networks, consortium blockchains can be more efficient and faster since the number of participants is usually smaller, and the need for consensus may be reduced. At the same time, they can offer a higher level of security and trust than fully private blockchain networks as they involve multiple organizations working together.
Types of blockchain networks

What does Blockchain mean?
A blockchain is a decentralized digital ledger that records transactions on multiple computers. The term blockchain refers to the ledger's structure, which involves creating a list of all transactions and sharing it with various computers worldwide.
One of the key benefits of blockchain is enabling multiple parties to reach a consensus on a shared database's state without the need for a central authority. This makes it a useful tool for securely tracking and verifying transactions and creating trust among parties who may not have a direct relationship.
Blockchain technology can help increase trust among network members by providing accurate and timely data that is only shared with those who have been granted access by the user. As a member-only network, blockchain ensures that confidential records are kept secure and only shared with those who have been authorized.
In a blockchain network, all members must agree on the accuracy of the data, and once transactions are validated, they are recorded permanently and cannot be altered or deleted. This ensures the integrity and immutability of the blockchain record.
By eliminating the need for a central authority or intermediary, blockchain allows for peer-to-peer transactions that can be processed more quickly and cheaply.
Some benefits of using blockchains
Blockchain is important because...
It has a wide range of potential uses and applications, including tracking digital currency transactions, managing supply chains, creating secure digital identities, enabling smart contracts, storing and managing electronic health records, and facilitating the buying and selling of real estate. As technology continues to evolve, new applications are likely to emerge.

Blockchains are widely used in cryptocurrency systems because they can securely and transparently maintain a decentralized record of transactions. They provide a way to verify the integrity and security of data without the need for a central authority. In this way, blockchains help create trust among parties involved in a transaction or exchange.
How are Blockchains used?
Banking and Finance
Blockchain never sleeps, so if you deposit a check on Friday at 6 pm, you don't have to wait until Monday morning to see the money in your account.
The blockchain can store medical records to provide patients with a tamper-proof record of their health information. By encoding the records with a private key, only authorized individuals can access the information.
Blockchain technology can streamline the process of verifying and recording property ownership by eliminating the need for physical documents and record-keeping. This can be particularly useful in areas with limited government infrastructure or affected by conflict, where proving ownership of property through traditional means can be difficult.
Smart contracts involve self-executing contracts where the terms of the agreement between buyer and seller are directly written into lines of code. The code and agreed-upon terms are stored and replicated on a blockchain network. Smart contracts allow for the automation of the contract execution process, reducing the need for intermediaries and potentially increasing efficiency and speed.
The food industry is increasingly using blockchain technology to trace the journey of food from the farm to the consumer, ensuring the safety and quality of the product. Suppliers can use blockchain to record the origins of materials, which allows companies to verify the authenticity of their products, such as whether they are "organic," "local," or "fair trade." This helps increase transparency and build trust with consumers.
Blockchain technology has the potential to improve the security and transparency of voting systems. By using blockchain to facilitate the voting process, it would be nearly impossible to tamper with votes due to the transparency and immutability of the blockchain. This could help increase confidence in the electoral process and ensure that the results accurately reflect the voters' will.
Retail loyalty rewards programs
By using tokens that are stored on the blockchain to reward consumers for their loyalty, retailers can incentivize customers to shop at their store or chain. This can revolutionize the way retailers approach customer loyalty and retention.
