What is Blockchain ?
Blockchain is a distributed ledger technology that allows records of transactions across several computers in a safe and clear manner. As it does not require any central authority to tamper with the data, the block is immutable and tamper-proof. The generalized application of this technology is seen in cryptocurrencies, smart contracts, and other industries for safe data management.
How Blockchain Works ?
A blockchain stores data in blocks, which are collected together in a chronological chain. Each block contains a cryptographic hash of the previous block; hence, if any alteration is done in the previous block, it can be recognized easily due to the change in the hash. Transactions are validated by a decentralized network of computers, and hence the system is secure and resistant to the entry of malware.
