Federated Cost Settlement Layer

Meter every inference.
Split costs by real usage.

Deploy a cost-sharing system for federated AI models where each consortium member pays their proportional share of inference costs based on verified usage. The Escrow and Conditional Settlement, External Data Oracles, and Audit Logs modules meter each member's consumption and allocate costs automatically, replacing the end-of-month manual calculation.

The Foundation

The Execution Mechanics

Turn a monthly manual cost allocation into an automatic split driven by verified inference usage.

01.

Inference Metering

Count usage at the source. External Data Oracles feed verified inference counts per member into the contract, so cost allocation rests on measured consumption rather than estimates.

02.

Proportional Allocation

Split by real share. The contract computes each member's portion of total inference costs from their verified usage, so heavier users carry proportionally more of the bill.

03.

Escrow Settlement

Collect and clear automatically. The Escrow and Conditional Settlement module holds member contributions and settles each period's shares without a treasurer running spreadsheets.

04.

Verified Consumption

Remove disputes over the numbers. Because usage is oracle-verified, no member can contest their share against the shared, tamper-evident record.

05.

Audit Logs

Keep a reconciled cost trail. The Audit Logs module records each period's usage and allocation, giving every member the same auditable statement.

06.

Consortium Transparency

Give all members one view. Every participant sees total costs, their usage, and their share in real time, ending the opacity of a single member computing the split.

The Cost-Sharing Lifecycle

Follow a billing period from metered inference through proportional allocation to automatic member settlement.

Smart Contract Anatomy

Cerulea decomposes federated cost-sharing into modular contracts. Each layer onboards members, meters usage, allocates cost, and settles without any single member controlling the calculation.

Applicability Across the Spectrum

Usage-based cost-sharing is a horizontal capability. Here is how different federated actors put the settlement layer to work.

Federated Learning Consortiums

Share the running costs of a jointly operated model by verified inference usage, so members settle proportionally each period without a treasurer reconstructing the split by hand.

Healthcare Data Alliances

Operate shared diagnostic models across institutions and allocate compute cost by each member's real inference volume, keeping cost fair as usage shifts between partners.

Finance & Audit Teams

Read the audit log to reconcile each period's usage and cost allocation, replacing a single member's spreadsheet with an authoritative, member-verifiable record.

Network & Execution Architecture

Whether you are bridging inference-serving infrastructure or reporting usage from member-operated nodes, Cerulea routes both into one cost record.

Track A: Serving Infrastructure Bridging

For consortiums on shared model-serving infrastructure. Verified inference counts are translated into on-chain usage records through the API gateway automatically.

Technical Methodology

The legacy timeline reflects distributed-systems and billing integration benchmarks. Building usage metering across serving infrastructure, encoding allocation logic, and wiring escrow settlement for an average consortium takes a baseline of 6 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your metering and allocation rules into pre-audited WebAssembly binaries and provisions the cost pool and audit layer instantly.
