The small set of primitives behind Foinse's payment, ledger, market, and native-inference spend paths.
Native keys and bearer compute value
A native provider key is provider-issued access. A payer may present a capped authorization around that key to a toll gate; the recipient never receives the key. Provider tokens are premetered, provider-denominated inference value. Once the charge settles, the transferable value is the bearer token balance recorded on Foinse's ledger. “Compute credit” or “claim” is optional ledger terminology, not another asset. See how it works.
FK1 and quota keys
FK1 is Foinse-issued access bound to one Foinse account. It permits account operations, ledger transfers, and native-inference spending through Foinse's spend path; it is not the rail, the money, or a native provider key. A quota key is only a capped authorization around a native key. See quota keys.
Door 1 and Door 2
Door 1 is historic: verify balance and custody before charging, then issue a signed, single-use, resource-bound qtt1 ticket. Door 2 is improved: make the exact charge as the measurement and use the committed movement event_id as the access grant. Both preserve backed value and exact accounting.
The toll
Initial processing tolls are provisional: 5% on compute-token movement, 5% for the Base USDC external-ramp family, and 5.5% for card. The seller receives the full listed subtotal; the buyer pays the disclosed toll on top. Foinse adds no separate software or account fee.
Exchange and pools
Available inventory pools within a provider-wide denomination, while reserve lots preserve provenance. Buyers acquire from the pool rather than selecting a named seller. Same-denomination transfer and native-inference spending are not exchange; exchange crosses provider denominations or enters and exits fiat and crypto.
Evidence grades
Proof surfaces use live, live-attested, attested, fixture-mechanism, and fixture labels. A label scopes what an artifact establishes; it does not imply product availability or an external audit. See the proof center.
Settlement
A settled movement satisfies payer debit = recipient credit + protocol fee. The ledger posts the complete conserved settlement or no settlement. See receipt verify.
