means A series of things—people, devices, exploits, favors—linked one after another so they act as a single connected sequence.

from From the literal child's craft of slitting daisy stems and threading flower through flower to make a linked garland or necklace—a known pastime by the 1800s. The phrase was transplanted into English figuratively for anything strung together in a line, then picked up by electricians and computer folk for wiring devices one into the next, and later by hackers for chaining exploits—each new sense keeping the original image of one flower's stem holding the next.
