A Block
is a single link in the chain that is Ethereum. Each Block
contains
a Header
and zero or more transactions. Each Header
contains associated
metadata like the block number, parent block hash, and how much gas was
consumed by its transactions.
Together, these blocks form a cryptographically secure journal recording the history of all state transitions that have happened since the genesis of the chain.
Header
Header portion of a block on the chain.
