Blockchain is now known as the decentralized, digital ledger technology which helps over recording which is termed as transactions across multiple computers which is i built to be encrypted with that of a secured and transparent way, hence it is also designed to be immutable, and as much as to record that which is regarded as data which cannot be altered or deleted as it makes blockchain highly secured and trustworthy.
Hence the record, or "block," which is linked to the previous one has to do with forming that of a "chain" of blocks which is now known as the blockchain itself, hence as the case may be every block contains three key components which is known as the data which has to do with the formation about the transaction (e.g., sender, receiver, amount) and as much as it's Hash which has a unique digital fingerprint that identifies the block and along side with the previous block’s hash.
Hence how Blockchain works has to do with transaction Initiation, verification, Mechanism, proofvof Work (PoW)** or Proof of Stake (PoS), therefore the blockchain is revolutionizing industries which now makes transactions more secure, efficient, and as much as making it transparent, hence as the case may be the cryptocurrencies now has potential applications across various sectors, which is after ensuring trust and as much as efficiency in digital interactions.
