Abstract
A system and method are disclosed in which a node of a peer-to-peer (P2P) network supporting a blockchain is able to restart following network or power disruption (or is able to initially join the blockchain network) by bootstrapping information from one or more peer nodes in the P2P network. The bootstrapping operation involves communication between the Trusted Execution Environments (TEEs) of the two or more nodes. The system and method ensure that the retrieval of data related to the blockchain state are not from untrusted parts of the peer node(s) and the data has not been tampered with (avoidance of replay attacks).
