The Java SDK for interacting with Hedera Hashgraph: the official distributed consensus platform built using the hashgraph consensus algorithm for fast, fair and secure transactions. Hedera enables and empowers developers to build an entirely new class of decentralized applications.
Hedera Hashgraph communicates using gRPC; the Protobufs definitions for the protocol are available in the hashgraph/hedera-protobuf repository.
