Blockchain is a public distributed peer-to-peer ledger which keeps the records in chronological order that are immutable and secure.
It is not any crypto-currency or a bitcoin, rather a distributed collection of immutable infrastructure code which is linked and secured with some fingerprint (crypto-hash) and is made accessible to the public on the internet. Real estate, health care services, financial transactions, and many other sectors use this tech structure to avoid any pitfall by using blockchain development .
High-end security features of blockchain technology
Hash cryptography: A hash is a fixed size alpha-numeric string which acts as a digital fingerprint for assembling data. It’s like algorithms that use the input data and produce a fixed-length output representing the fingerprint of the data.
Immutable ledger: Immutable in terms of blockchain means that once the data has been recorded in a public ledger, non can alter it. If a hacker tries to change anything in the block then the hash will not match the previous hash, and the hacker will have to change block after block. Thus, this practice helps to keep data secure.
Distributed p2p network: In this network, data is not stored in one centralized point, which makes data difficult to being hacked or exploited. As there is no dominant force, so the owner becomes the true owner of their personal data.
Mining: It is a practice of adding transactions in the distributed public ledger. It helps in creating a hash of block for transactions which cannot be forged easily. Therefore, mining is the system that allows the blockchain to be a decentralized security.
