*5.1. Peer Node*

As mentioned in Section 3, a peer node of HLF performs the following operations:


The "Generating snapshot" operation is modified to transmit the blocks to the remote DB server and delete the blocks from its local file system. The "Responding query requests" operation is also modified by adding verification process after the blocks and transactions are retrieved from the remote DB server. The communications between peers and the remote DB server are realized by way of a GRPC protocol [44]. The "Endorsing" and "Committing" operations remain unmodified.
