What is blockchain technology?

Blockchain technology is widely applied and has been around for a while. But, common people's interest in this technology was created mainly after the invention of cryptocurrency named Bitcoin. Blockchain is, in theory, a publicly accessible distributed ledger.

A piece of data is nearly impossible to remove once it is added to the blockchain's blocks or to alter in any way. You must first understand what these blocks contain. Three components make up each block in a fully operating blockchain: data, hash, and the hash of the block in the chain that came before it. Meaning that every block on the blockchain contains hashes of previous blocks in addition to personal data.

What are some real-world applications of blockchain technology?

Blockchain, in technical terms, is an open distributed ledger. Blockchains exhibit remarkable resistance against manipulation and censorship because to their lack of reliance on a centralized authority or single point of control.

Blockchain enables secure and interoperable sharing of medical data between parties that have adopted blockchain in the healthcare sector. It enhances patient care, reduces fraud, reduces errors and maintains the privacy of sensitive information.
Peer-to-peer networks and digital signatures are combined. A number of individuals who act as authorities use digital signatures to reach consensus on transactions, among other things. So, to summarize, blockchain users use cryptography keys to perform various types of digital interactions through a peer-to-peer network.

What are the key differences between public and private blockchains?

• A private blockchain allows only selected and verified participants; The operator has the right to override, edit or delete entries in the blockchain.A public blockchain is accessible to everyone and is decentralized. It works in a permissionless manner, meaning anyone can join, validate transactions, and even participate in the consensus process in exchange for rewards. Its transparency and security are supported by a wide and diverse network of nodes. Because of their open, immutable, and censorship-resistant characteristics, public blockchains are transforming confidence in direct online transactions.

• Enterprises, groups, and governmental entities frequently employ private blockchains to provide transparent and safe documentation processes. Sensitive data can benefit from extra protection and control over who can access network data thanks to private blockchains. In addition, a private blockchain is more centralized because a single authority maintains the network.
