A sovereign cell is a full economy - its own chain, its own currency, its own validators, and its own law written directly into consensus. Cells are the building blocks of the JIL Federation, and JIL.ai is what you spend to stand one up.
The word "sovereign" is doing real work here. A sovereign cell is not a smart contract, a subaccount, or a rollup that inherits someone else's rules. It is a self-governing chain that controls its own money and its own law. To understand the JIL Federation, start with the cell.
Four things belong to the cell and to no one else:
That last point is the heart of it. When policy lives in consensus, a regulated institution can run a chain whose rules are structural, not optional. Gas inside a cell is paid in ujil; the higher-level federation services a cell uses are paid in JIL.ai.
Not every operator needs the same degree of control, so cells come in three tiers - a spectrum from turnkey to fully self-run:
The turnkey tier. The operator gets a cell without having to run the underlying infrastructure themselves - the fastest way to stand up an economy on the federation. Good for teams that want the capability without the operational burden.
The compliance-forward tier, built for entities that must operate inside a regulatory perimeter. Compliance policy is wired into the cell, so KYC, screening, and Financial-DNA checks are enforced at the consensus layer. This is the tier that fits licensed financial activity.
The maximum-control tier. The operator runs their own infrastructure and holds the fullest degree of sovereignty over the cell - its validators, its keys, its law. Suited to national-scale or institution-scale deployments that need to own the whole stack.
A cell is not a walled garden for one language. Cells can run Ethereum-native transactions - you can deploy Solidity contracts the way you would on Ethereum, with familiar contract addresses and an Ethereum-style RPC interface. That means the enormous existing world of EVM tooling and contracts can target a JIL cell directly, while still living under the cell's sovereign law.
Sovereignty would be isolating if cells could not transact with one another. They do, through trust-minimized corridors: one cell's light client verifies another cell's actual consensus - the real validator signatures - with no central hub in the middle. Value and proofs move across sovereign borders without a trusted intermediary. Opening and running those corridors is metered in JIL.ai, which is why the token's usefulness grows as the federation adds cells.
Standing up or licensing a cell - at any of the three tiers - is paid in JIL.ai, through the cell provisioner and its certification gate. Cell provisioning is the first of JIL.ai's five live utilities, and it is the one that seeds all the others: every new cell is new demand for corridors, proofs, and compliance metering, all of which are also paid in JIL.ai.
