What is Delegator?

A delegator is a type of node that is often employed by Proof-of-Stake (PoS) blockchain networks. Delegators have a diverse range of purposes depending on the specific blockchain protocol they operate on, but they are generally used to help full nodes or validator nodes, which are the primary nodes responsible for carrying out network consensus. Those who wish to participate in consensus, but don't wish to operate a full node, may become a delegator node and stake their coins/tokens with a public validator node — through a process called delegation — to share in a portion of block rewards.
