Definition: PoC

(1) (Proof Of Concept) See proof of concept, proof-of-concept virus and proof-of-concept exploit.

(2) (Proof-Of-Capacity) A blockchain consensus method. See proof-of-capacity algorithm.

(3) (Power Over Cable) Sending data and power over the same line. See PoE and HDBaseT.

(4) (Power Over Coax) Using coaxial cable to send PoE (Power over Ethernet) signals a distance of a half mile or more. The PoC device converts PoE to a coaxial-compatible signal that is transmitted to the PoC unit at the other end. See PoE.
