The core value unit on the Guardians of Earth platform, representing proof of a biocultural connection to a Nature Realm. Total supply is capped at one million BCUs forever. Scarcity increases exponentially: the BioScore required to harvest a BCU rises over time. BCUs can be acquired through harvesting (raising a Realm’s BioScore by contributing data or knowledge), staking, or buying via the BCU marketplace. Purchase money is distributed to harvesters, with 10 percent to verifiers on the Oracle of Life.
