Abstract: An example operation may include one or more of retrieving, into a new node to be instantiated in a blockchain network, a state database checkpoint of a state database created at a block number of a blockchain of the blockchain network, retrieving, into the new node, blocks of the blockchain from the checkpoint block number to a current block number, constructing an initial state database from the received state database checkpoint, and executing, at the new node, the transactions of the retrieved blocks on the initial state database to generate a current state database.

Abstract: An example operation may include one or more of retrieving, into a corrupted node in a blockchain network that is at least one corrupted or forked, a state database checkpoint of a state database created at a block number of a blockchain of the blockchain network, wherein the retrieved state database checkpoint comprises a last known non-corrupted or non-forked checkpoint state, retrieving, into the corrupted node, blocks of the blockchain from the checkpoint block number to a current block number, constructing an initial state database from the retrieved state database checkpoint, and executing, at the corrupted node, the transactions of the retrieved blocks on the initial state database to generate a current state database.
