Block chain

It works with Blocks, whereas spreadsheet works with “rows” and “columns”.

A block in a blockchain is a collection of data. The data is added to the block in the blockchain, by connecting it with other blocks in chronological others creating a chain of blocks linked together. The first block within the Blockchain is called Genesis Block. Blockchain is a distributed ledger, which simply means that a ledger is spread across the network among all peers in the network, and each peer holds a copy of the complete ledger.
