# What is BlockMap?

The BlockMap NFT combines network block data, programming, and art.

The BlockMap is a next-generation NFT collection, where each piece contains the data of a network block. 

The NFT contains the following data:

* Power - NFT's Power property
* Class - NFT's Class property
* BlockHeight - The block height, which indicates the length of the blockchain, increases after the addition of the new block
* BlockSize - Network block size in bytes
* GasLimit - Total gas limit provided by all transactions in the block
* GasUsed - Total gas used in the block
* Timestamp - The date and time at which a block is validated
* Transactions - Number of transactions in the network block
* Explorer - Where the network block data can be viewed

The 'power' and 'class' properties are set during the NFT generation according to predefined rules.
