In order to participate in the Beacon Chain, a Beacon Chain client (or node) is required.

Beacon nodes

The beacon node is the primary link in the Beacon Chain that forms the central core of the Ethereum blockchain. The beacon node’s responsibilities include the synchronization of the Beacon Chain with other peers. It performs the attestation of blocks and runs an RPC server to provide critical information to the validators regarding assignments and block attestation. In addition, it also handles state transition and acts as a source of randomness for the validator assignment process.

Note that we use node and client interchangeably. However, there is a subtle difference between the terms client and node: when we say client, it actually means the software client that performs the functions of consensus or execution, whereas a node can be seen as a combination of client software and the hardware (computer) that it is running on. Generally, however, client and node are used interchangeably.
