The structure of the Ether blockchain is very similar to Bitcoin, as it is a shared record of the entire transaction history. Each node on the network stores a copy of this history.
The major difference between Ether and Bitcoin is that in addition to all Ether transactions, its nodes store the latest status of each smart contract. For each Ether application, the network needs to keep tracking the "state" or the current information of all these applications, including the balance of each user, all smart contract codes, and their storage locations.
