This question already has an answer here:
Ethereum uses Accounts instead of UTXO (Bitcoin). I would like to know how does the ledger keep the account state (technical details if possible)?
- Does it modify the ledger (accounts) by incrementing or decrementing the balances?
- Or does it use the cumulative (sum) of received amounts and send to verify users have a proper balance?
- Where does the Patricia-Tree used stand in all of this?
