The present invention may also include reading the trusted node blockchain by the non-trusted node. The present invention may then include creating, by the non-trusted node, a new block on a temporary blockchain based on the read trusted node blockchain. The present invention may further include transmitting, by the non-trusted node, the created new block to the trusted node, wherein transmitting the created new block causes the created new block to be added to the trusted node blockchain.
