Introduction to Blockchain
Blockchain technology is a decentralized and transparent system t allows multiple parties to maintain a shared digital ledger without a central authority. It enables secure and immutable recording of transactions, making it suitable for various industries and use cases.
A real-life example of blockchain technology is Bitcoin, the first and most well-known cryptocurrency. Bitcoin uses blockchain as its underlying technology to enable peer-to-peer transactions without the need for intermediaries like banks. The blockchain serves as a public ledger that records all Bitcoin transactions in chronological order, which can be accessed and verified by anyone in the network.
With blockchain, each transaction is grouped into a block, and these blocks are linked together using cryptographic hashes, forming a chain of blocks. Once a block is added to the blockchain, altering or deleting the information within it becomes virtually impossible, providing high transparency and immutability.
Blockchain technology is also being explored and implemented in industries beyond cryptocurrencies. For instance, in supply chain management, companies like IBM have developed solutions like IBM Food Trust, which utilizes blockchain to enhance transparency and traceability in the food supply chain. It enables consumers, retailers, and producers to track the journey of food products from farm to table, reducing fraud, improving food safety, and increasing trust among stakeholders.
Blockchain technology provides a decentralized and secure method of recording and verifying transactions. Its applications extend beyond cryptocurrencies and can be used in various industries to enhance transparency, security, and efficiency in processes involving multiple parties.

What are the types of Enterprise Blockchains?
There are several enterprise blockchains, each with characteristics and suitability for different use cases. The main types of enterprise blockchains include:
Public blockchains are open and permissionless, allowing anyone to join the network, participate in consensus, and validate transactions. While not specifically designed for enterprise use, some organizations may leverage public blockchains for specific applications. Public blockchains, such as Bitcoin and Ethereum, provide a high level of decentralization and transparency but may have limitations regarding scalability and privacy.
A private blockchain, also known as a "permissioned blockchain," is restricted to a specific group of participants permitted to participate and operate the network. These participants are typically known and trusted entities, such as consortium members or employees within an organization. Private blockchains offer more privacy, scalability, and control than public ones. Examples of private blockchain platforms include Hyperledger Fabric and R3 Corda.
Consortium blockchains are a variant of private blockchains where multiple organizations come together to form a shared blockchain network. Consortium members jointly manage the network and participate in consensus mechanisms. Consortium blockchains are suitable for use cases where multiple entities must collaborate while maintaining a certain level of trust and control. They are often found in industries such as supply chain management and finance.
Hybrid blockchains combine properties of public and private blockchains. They provide a flexible architecture that allows certain parts of the blockchain to be public while others remain private. This allows for a balance between transparency and privacy, accommodating various use cases. Hybrid blockchains can enable interoperability between public and private networks or provide selective data sharing between participants.
Federated blockchains, or consortium blockchains with enhanced governance, are designed for situations where a limited number of pre-selected nodes or validators control the consensus process. This model provides higher scalability and faster transaction confirmation times than fully decentralized blockchains. Federated blockchains are commonly used in enterprise environments where efficiency and performance are crucial.
Permissioned vs. Permissionless
While not distinct types of blockchains, the permissioned vs. permissionless categorization refers to the level of access and participation in a blockchain network. Permissioned blockchains require participants to be granted explicit permission to join and operate the network, ensuring a controlled and trusted ecosystem. On the other hand, permissionless blockchains allow anyone to join and participate, emphasizing openness and decentralization.
It's important to note that the choice of blockchain type depends on the specific requirements, privacy needs, scalability concerns, and governance considerations of an enterprise use case. Enterprises may combine different types or customize existing blockchain frameworks to meet their unique needs.
