A method includes sending, by a consensus node of a blockchain network, current state information and one or more transactions associated with a current block of a blockchain to one or more shared storage nodes of the blockchain network, wherein the consensus node stores block header associated with every block of the blockchain and the current state information, the one or more shared storage nodes store block body and historic state information associated with every block of the blockchain, and wherein the historic state information is stored as key-value pairs (KVPs) of a historic state tree with values being account states of accounts associated with the blockchain network and keys being hash values of the corresponding account states; verifying that the one or more transactions are stored by the one or more shared storage nodes; and receiving a notification of a transaction associated with the consensus node.
