What do you mean by blocks in Blockchain technology?

Blockchain is a distributed database of immutable records called blocks, which are secured using cryptography. Refer to the video to see the various attributes of a block.

There are a previous hash, transaction details, nonce, and target hash value. A block is like a record of the transaction. Each time a block is verified, it gets recorded in chronological order in the main Blockchain. Once the data is recorded, it cannot be modified.
