The NFT contains the following data:

* BlockSize - Network block size in bytes

* 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

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