Data is stored in blocks and how the proof of work is achieved and the immutability of data are the new concepts of blockchain.

Blockchain is a decentralized database distributed across the network
Blockchain always only stores the hashes of the data.

Answer 2

The distributed ledger database is spread across several nodes (devices) on a peer-to-peer network, where each replicates and saves an identical copy of the ledger and updates itself independently. The primary advantage is the lack of central authority.

Answer 3

What does a block contain??

Field	Description	Size
Magic no	value always 0xD9B4BEF9	4 bytes
Blocksize	number of bytes following up to end of block	4 bytes
Blockheader	consists of 6 items	80 bytes
Transaction counter	positive integer VI = VarInt	1 - 9 bytes
transactions	the (non empty) list of transactions
