 ## Introduction
 
-Janus Facing Architecture — named for the Roman god who looks in two directions at once, just as every economic participant faces demands for both production and consumption — allows communities to address the economic reality of prosumership. Every member of an economy is not just a consumer, but a prosumer (Toffler, 1980), simultaneously producing something of value even if all they have to offer is time. It also provides an option to transform the issuance model from exogenous, chartal money (issued by an authority outside the community) to endogenous mutual credit (issued by members to one another as they transact).
+Every member of an economy is a **prosumer** — not only a consumer, but at the same time a producer of something of value, even if all they have to offer is time (Toffler, 1980). Nobody stands on only one side of a trade; the two faces are the same person.

+Janus Facing Architecture is named for the Roman god who looks in two directions at once, because that is what every prosumer does: each faces demands for both production and consumption, at the same time. It allows communities to address the economic reality of prosumership, and provides an option to transform the issuance model from exogenous, chartal money (issued by an authority outside the community) to endogenous mutual credit (issued by members to one another as they transact).
 
 The name's second face is political. Acemoglu and Robinson (2019) show that liberty survives only inside a narrow corridor where a capable state — the Leviathan — is matched by a society equally capable of checking it. Outside the corridor the Leviathan takes its other forms: absent, and coordination fails; despotic, and the coordinator dominates the coordinated; paper, and the checks exist in writing but not in effect. Staying inside the corridor demands what they call the Red Queen effect: state and society running together, each growing capacity because the other does. Every economic platform is a Leviathan in miniature — it coordinates, enforces and records — and today's dominant platforms are despotic by construction, evolving at network speed while the institutions meant to check them move at the speed of meetings.
