In Ethereum or EOS, concept of Accounts make it important to keep track of 'current state'. (e.g.) current balance of Account A is 300 EOS. Especially in Ethereum, roothash of state tree is stored in every block.
Bitcoin, on the other hand, doesn't care nor store information of current state. I know wallet applications gather block data and derive current balance of the user.
But my question is, do Bitcoin miners keep track of current 'state' of bitcoin blockchain?
