Every dominant monetary system in history derives its value from a structural demand mechanism rather than from intrinsic properties of the medium itself. Commodity-backed currencies derive demand from the stored value of the commodity; fiat from legal tender mandates and tax obligations; the US dollar from its role as the mandatory settlement currency for global oil trade — the petrodollar mechanism. Yet no existing monetary model systematically links currency emission to investment in the productive domain that generates structural demand. This paper introduces the Domain-Value-Backed Currency (DVBC) model, in which (a) all commercial transactions in a defined high-value domain settle in the currency, (b) emission is mechanically linked to investment in that domain's productive capacity, and (c) the protocol is governed by token holders. The result is a self-reinforcing loop: emission funds research, research produces commercial outputs, commercial outputs require the currency for settlement, settlement demand attracts capital, and capital funds more research. We formalize the model, prove its theoretical superiority over the petrodollar in terms of emission–demand coherence, and demonstrate its implementation in Metha Biofund — an open-source Ethereum protocol deployed on Sepolia testnet with five interconnected smart contracts validated by 50 automated tests. Metha currently satisfies conditions (b) and (c) on-chain; condition (a) — mandatory METH settlement for biomedical IP — is established as a future governance decision with the on-chain infrastructure already live. We argue health is the ideal first DVBC domain, examine generalization to energy, education and software, and identify the cold-start problem and regulatory treatment of mandatory settlement as the primary open challenges.
