A Node is a member of a decentralised blockchain which connects to the network.
A node can have different roles within a network. For XODEX, there are three node types:
A validator node has the authority to propose new blocks on the blockchain.
A validator must also verify other validator block proposals for the network to reach consensus.
A member is a standard node that typically replicates and stores the blockchain's ledger.
A Remote Procedure Call (RPC) node is a software server that enables users to read data and send transactions on a blockchain. RPC nodes allow the various components that make up a decentralised app (DApp).
