Blockchain Technology – The main application of the blockchain is to carry out transactions on a secure network. It is the reason why people are using blockchain and ledger technology in different scenarios. Anyone can set up multiple networks to prevent unauthorized access to sensitive data. It is not publicly available and may only be accessed by authorized entities within the organization. It depends on the organization as to what type it needs to operate.
How Does Blockchain Technology Work?
The purpose of the blockchain is to allow digital information to be recorded and distributed, but not published. As such, blockchain is the basis of an immutable ledger or transaction record that cannot be modified, deleted, or destroyed. It is the cause why Blockchain is also known as Distributed Ledger Technology (DLT).

Is the Blockchain Secure?
Blockchain technology provides decentralized safety and trust in several ways. First, new blocks are always stored linearly and chronologically. In other words, they are constantly added to the “end” of the blockchain. Hash codes are generated by a mathematical purpose that converts numeric information into a string of numbers and letters. If this information is changed in any way, the hash code also changes.

Types of Blockchain Technology Networks
Public Blockchain Network
A community blockchain is a blockchain that anyone can join and participate in, like Bitcoin. Disadvantages include the need for significant computing power, little or no privacy for transactions, and little security, which are essential considerations for enterprise blockchain use cases.
Private Blockchain Network
Like a public blockchain network, a private blockchain network is a decentralized peer-to-peer network. However, the organization controls the network, controls who can participate, implements the consensus protocol, and maintains a shared registry. Depending on the use circumstance, this can significantly increase trust between participants. The private blockchain can be run behind a corporate firewall and even hosted on-premises
Certified Blockchain Network
Companies that establish private blockchains typically establish a network of licensed blockchains. It is vital to note that public blockchain networks can also be authorized—set limits on who can participate on the web and what transactions. Participants must receive an invitation or consent to join.
Multiple organizations can share maintenance responsibilities for a blockchain, and these predefined organizations determine who can submit transactions or access data. A consortium is ideal for a blockchain business when all participants request authorization and share responsibility for the blockchain.

Benefits of Blockchain Technology
- Experts cite several vital benefits of using blockchain.
- Security is probably the most crucial benefit. Corrupting a blockchain is nearly impossible because thousands, if not millions, of computers, are constantly sharing and collating information. There is no single point of failure in the blockchain.
- Transactions can be more efficient than non-DLT-based transaction systems, although public blockchains can sometimes suffer from slowness and inefficiency.
- It is flexible: if one node goes down, there is no problem because all other nodes have a copy of the registry.
- It ensures trust among the participants in a network. Compromised blocks are tough to reverse, so deleting or modifying data is difficult.
- It can be profitable because it often reduces transaction expenses by eliminating intermediaries and third parties.

Disadvantages of Blockchain Technology
- Experts say that blockchain also has probable drawbacks, risks and tasks.
- Public blockchains have queries about ownership and who is accountable if something goes wrong.
- There are also queries about whether organizations are able or willing to invest in the
- infrastructure needed to build, participate and maintain a blockchain-based network.
- Changing data on a blockchain is usually a lot of work.
- Users should keep an eye on their private keys to avoid losing money.
- The storage can become very large over time, leading to node loss if the log is too large for users to download.
- The blockchain is susceptible to 51% attacks, a specific attack designed to overwhelm other network participants and change blocks.

Blockchain Technology Privacy and Security
Security is considered one of the main advantages of blockchain. Blocks are always kept chronologically, and it is challenging to change blocks once they are added to the end of the blockchain. Each block has its hash code and the hash code of the previous block. If a hacker tries to modify a partnership, the block’s hash will change, meaning that the hacker will have to change the hash of the next block in the chain, and so on. So to replace one block, a hacker would have to replace all the other blocks that followed it, which would require a lot of computing power.

With many practical applications of the technology already implemented and explored, blockchain is finally making a name for itself, thanks partly to Bitcoin and the cryptocurrency itself. As the voice of all investors in the country, Blockchain makes business and government processes more accurate, efficient, secure and affordable with fewer intermediaries.
