What is Blockchain Technology?


Every blockchain network has a ledger, whether public or private. A ledger is a digital record of transactions that are carried out over an internet network. Most blockchains have public ledgers, which are open to the public and allow people to audit transactions. Others have private leders, which allow third-parties to audit transactions. In this blog, we discuss blockchain technology and how it is revolutionizing the internet and businesses today. We also compare bitcoin with blockchain technology so that you can understand the difference between the two.

What is Blockchain Technology?

– Blockchain technology is a digital ledger of economic transactions that is distributed across peer-to-peer network of computers.

– It is a decentralized, distributed ledger that records the digital assets of two parties efficiently and accurately.

– The ledger technology underpins cryptocurrencies like Bitcoin, providing a strong line of security against hacking and manipulation due to its decentralized nature.

– It is widely used across various industries, such as banking and finance, healthcare, record-keeping, smart contracts, supply chains, and even voting.

– Blockchain technology is protected against double-spending attacks in payments and money transfers.

– It offers transparency and traceability of digital assets, making it an exciting alternative to the current database technology.

Blockchain technology has the potential to revolutionize many sectors of the economy and has the potential to impact lives in significant ways.

Bitcoin vs. Blockchain

– Bitcoin and blockchain are two different technologies. Bitcoin is a digital currency, while blockchain is a distributed ledger of transactions and records.

– Bitcoin is decentralized, meaning it doesn’t have a central authority or bank controlling its supply and transactions are anonymous.

– Ethereum, another cryptocurrency, has more capabilities than bitcoin and allows smart contracts and apps to be built on it.

– Blockchain is a database of transactions that have taken place between two parties, with blocks of data containing information about each transaction being added in chronological order to the chain.

– Blockchain technology was first used to track bitcoin transactions, but it has been adopted by many industries for applications such as digital ledger for e-commerce, digital ledger of proof of assets ownership, digital ledger of medical records, digital ledger of land titles and other uses.

– Bitcoin uses blockchain technology as its transaction ledger.

Types of Blockchain Networks

– Public blockchains are “permissionless” and allow anyone to read, submit transactions, or participate in the consensus process. These blockchains have no central authority and are managed by a network of blockchain validators.

– Semi-private blockchains are run by a single company and allow access to users who meet certain criteria, such as being an active user of the network or holding an authorized key. This type of blockchain offers features similar to both private and public blockchains, such as smart contract functionality, peer-to-peer transactions, and decentralized consensus.

– Private blockchains are also run by a single organization and offer features similar to both private and public blockchains, such as smart contract functionality, peer-to-peer transactions, and decentralized consensus. In addition to smart contracts and digital currencies like bitcoin, private blockchains can also support tokens issued by organizations of all kinds.

– Finally, hybrid blockchains are a combination of private and public blockchain networks. They use both a public blockchain as the ledger for digital assets like cryptocurrencies and digital currencies issued by institutions, while maintaining private blockchain technology for smart contract execution, peer-to-peer transactions, and decentralized consensus.

The main difference between these types of blockchain networks is the level of decentralization they use – public blockchains are more decentralized than semi-private blockchains but still centralized relative to private blockchains.

With so many blockchain options available today, it’s easy to become overwhelmed by the range of features offered. However, careful consideration of the different types of blockchain networks will help you better understand why each one is suitable for your particular use case.

Benefits of Public Blockchain Networks

Public blockchains are open and decentralized networks for anyone to join and verify transactions. They use consensus algorithms such as proof-of-work or proof-of-stake to validate transactions. This means that public blockchains help to reduce security risks and centralization issues. Instead, public blockchains enable data to be distributed across a peer-to-peer network. This makes them ideal for exchanging and mining cryptocurrencies like Bitcoin, Ethereum, and Litecoin.

Public blockchains are widely used in many industries due to their transparency and security benefits. They can be useful for a range of applications, from cryptocurrencies to smart contracts and digital currencies. In short, public blockchain technology provides a shared ledger that allows digital assets to be securely transferred between parties with minimal downtime or third-party verification.

Benefits of Private Blockchain Networks

Private blockchain networks offer many benefits over public blockchain networks, largely due to the governing organization controlling who is allowed to participate, execute a consensus protocol, and maintain the shared ledger. Because private blockchain networks can be run behind a corporate firewall and hosted on premises, they allow for greater control and security. Companies can use private blockchain networks to create digital collectibles or smart contracts, which are complex decentralized financial products that can handle peer-to-peer transactions with high smart contract functionality.

Another benefit of private blockchain networks is that they allow users to keep their personal information private and secure while still allowing public access to digital currency. By allowing users to transact private currencies instantly, private blockchains increase the efficiency of digital payments. This technology is especially useful for financial institutions looking to reduce costs and speed up transaction times by making smart contracts run on a private blockchain network instead of a public one.

What is a Permissioned Blockchain Network?

A private blockchain network is a permissioned blockchain that enables special access to authorized individuals. By allowing only certain participants to join the network, a private blockchain can provide organizations with more control over who can participate in the network and in what transactions. A private chain requires approval from each node before it can join the network. Public blockchains are open and permissionless, meaning anyone can join and establish a node. These networks typically use cryptography and a consensus system such as proof of work (PoW) to secure their network.

A private blockchain network is often limited to a specific group of users with special permissions, so it can be useful for businesses looking to maintain strict control over access and data. However, public blockchain technology is more flexible and can be used by any party without requiring permission. For this reason, public blockchain tends to be more dynamic and versatile than private blockchain technology.

What is a Consortium Blockchain Network?

A consortium blockchain network is a distributed database or ledger shared among multiple organizations. It is permissioned and the consensus process is determined by a pre-selected group of corporations. A consortium blockchain network is an optimal method for collaboration between multiple organizations, offering improved security and transparency.

Unlike a typical database in which information is stored in individual nodes,information in a consortium blockchain network is stored in groups of blocks known as chains. Each block stores specific data such as transaction hash or data about the previous block in the chain, which forms a chain of data. This unique structure makes it suitable for use in real-world applications where data must be validated but privacy must be guaranteed.

However, consortium blockchain networks are not suitable for actual production as they are 100% centralized. They work best when multiple organizations work together to process and validate transactions and store their records in the distributed ledger.

Benefits of Consortium Blockchain Networks

A consortium blockchain network is a blockchain network that involves multiple organizations working together to create a distributed ledger technology (DLT) that provides improved security and cost-efficiency over other blockchain networks.

By involving multiple entities in blockchain technology development, consortium blockchains reduce the cost of trust between companies involved in the network. This can help improve business processes between companies and enable them to move faster and more efficiently.

consortium blockchains offer scalability and efficiency of digital assets, making them ideal for businesses looking to streamline operations and increase efficiency. Overall, consortium blockchains provide an efficient way for organizations to work together and develop new technology quickly and effectively.

Challenges of Public Blockchain Networks

Public blockchains are public, decentralized networks that allow anyone to participate. However, public blockchain networks face security challenges due to centralization. Public blockchains use consensus algorithms such as proof of stake (PoS) and proof of work (PoW) to verify information authenticity. However, these consensus algorithms can be vulnerable to attacks. The lack of access restrictions and computational power required by public blockchain networks makes them prone to security flaws and other challenges.

Public blockchains also have little or no privacy for transactions, which makes them weak targets for hackers. Instead, public blockchain networks require substantial computational power and offer limited privacy, making them less attractive as a technology for financial transactions. In addition, public blockchains are generally not able to scale to handle high-volume transactions, making them less viable for use in financial services applications.

By eliminating certain security challenges and issues public blockchains can be more secure and efficient than private blockchain networks. However, public blockchain networks still have their own set of challenges and must continue evolving to meet the ever-growing demand for digital services and technology.

Challenges of Private Blockchain Networks

Private blockchain networks require one organization to manage access and authorization preferences, parameters to the network, and other important security options. This can be a challenge in private blockchain networks as there is only one entity responsible for granting access to the network. In private blockchain networks, users must comply with specific rules and requirements to participate in the network. Additionally, private blockchain networks require additional security measures such as firewall technology or encryption to ensure data confidentiality and privacy.

Private blockchain networks may lack the trust and confidence of public networks due to their single-entity management model. This can make it difficult for public blockchain networks to scale rapidly. Also, public blockchain networks are more easily accessible and more open for use by third party applications and services. Therefore, private blockchain networks may have limitations that public blockchain networks do not face. Overall, private blockchains offer a unique set of benefits and challenges that make them best suited for private use cases.


Blockchain technology is an exciting new technology that is still evolving. It promises to revolutionize many aspects of digital transactions, ranging from financial services and digital assets transfer to contract verification and e-voting. With blockchain technology, organizations can reduce transaction costs, strengthen security, and improve transparency while also ensuring data integrity. Besides, blockchain technology allows for peer-to-peer transactions without the need of third-party verification. Many industries are already exploring blockchain technology applications to improve transparency, security, and efficiency.
