+ A ZooBC release can ship a **release pin**, also called the spine pin: a small public file that names one block of the [[spine-chain|spine chain]] by its height and hash. At start-up a node compares its own spine with the pin and refuses to run on a spine that contradicts it. The pin gives an installation one trusted anchor that comes with the software itself, so a forged spine history is refused before the node builds anything on it.
