Cost estimator

The Linear Leios (CIP-164) cost estimator tool estimates operating costs for running a Leios node. It integrates resource usage data — CPU, disk, network egress, and IOPS — to translate confirmed transaction throughput (TxkB/s) into projected monthly expenses for stake pool operators. See the detailed cost analysis for methodology.

How it works​

The primary input is confirmed throughput in TxkB/s (transaction kilobytes per second reaching the ledger). The tool computes per-node resource requirements using the CIP-164 protocol parameters (active slot coefficient, voting window, votes per EB) and benchmark data (validation times from db-analyser and cryptography prototypes). Cloud cost presets let you compare hyperscale providers against discount providers.

Example use cases​

  1. Stake pool budgeting: Operators can evaluate whether their fee revenue will cover a projected monthly cloud invoice at different throughput levels.

  2. Protocol parameter exploration: Adjusting the voting window, vote committee size, or fetch multiplicity shows how these parameters affect CPU overhead and network egress.

  3. Provider comparison: The cost presets for hyperscale and discount providers highlight where egress-heavy workloads benefit from providers with generous included transfer.
