//Block Header

Block Header

The header of each block consists of three items which are• Chainnumber: the unique chain number is assigned sequentially startingfrom zero. The first chain is a special chain and it’s MainChain.• Blocknumber: the unique block number. the structure of Block number is:BlockMainChainNumber – BlockNumber. The first block in a chain is special and is called genesis block which gets zero as its number. So, the genesis block of a private chain generating by the second block of MainChain will have Blocknumber 2-0• PreviousHash:hash of the previous block’s header. The PreviousHash of the genesis blocks is set to nULL. the PreviousHash of the next block holds SHa256 hash of BlockHeader of the previous block.• DataHash: hash of the data segment of the current block. the DataHash holds SHa256 hash of BlockData of the current block.• MainBlockHash: hash of the block in MainChain generating the private chain.​https://ift.tt/2FfJs57

The header of each block consists of three items which are

• Chainnumber: the unique chain number is assigned sequentially starting

from zero. The first chain is a special chain and it’s MainChain.

• Blocknumber: the unique block number. the structure of Block number is:

BlockMainChainNumber – BlockNumber. The first block in a chain is special and is called genesis block which gets zero as its number. So, the genesis block of a private chain generating by the second block of MainChain will have Blocknumber 2-0

• PreviousHash:hash of the previous block’s header. The PreviousHash of the genesis blocks is set to nULL. the PreviousHash of the next block holds SHa256 hash of BlockHeader of the previous block.

• DataHash: hash of the data segment of the current block. the DataHash holds SHa256 hash of BlockData of the current block.

• MainBlockHash: hash of the block in MainChain generating the private chain.
