FORTH is Ampleforth’s (AMPL) governance token. FORTH holders can vote on proposed changes to the Ampleforth protocol or delegate their votes to representatives who vote on their behalf.

AMPL is the first ever rebasing cryptocurrency. Like Bitcoin, AMPL is non-dillutive. Unlike Bitcoin AMPL can be used to denominate contracts of predictable value. Where AMPL represents an independent currency that functions as a unit of account, FORTH is the governing mechanism that oversees its evolution.

FORTH was launched by the Ampleforth team as a "Day One launch" in conjunction with Coinbase in April of 2021.
