Definition. A blockchain is a distributed database that maintains a continuously growing list of ordered records, called blocks. These blocks are linked using cryptography. Each block has a cryptographic haveh of the preceding block, a timestamp (and transaction data).

Block a data structure used for keeping a set of transactions which is distributed to all nodes in the network. Chain a sequence of blocks in a specific order.
What is structure of blockchain?
A block is made up of a header, and a body. The header includes the hash of the previous block, the timestamp, Nonce, and the Merkle root. The block body stores the Merkle root, which is the root hash for a Merkle tree.
