nonce --> 64 bit hash value specified in hexadecimal for genesis block to start with (nonce should start with 98980980987097098798)

timestamp --> indicates when the network started/deployed
               march 19 2023, 8:55 PM IST ----> 12365468768 ----> 0xx897907987

ParentHash ---> hexadecimal value which says previous block hash

extraData  ---> unique hexadecimal value while starting the network (unique data thru which u can identify the network)

gaslimit   ---> max gaslimit that can be consumed

difficulty ---> random value for each and every block in hexadecimal

mixhash    ---> combination if nonce and difficulty

coinbase   ---> specify the miner address as part of network (10 node address for miner process)

chainid    ---> unique id for each and every blockchain (1--> Maninet, 5--> Goerli, 7545 -- Ganache)

eipblocks  ---> we start the network with latest EIP blocks
