A revenue model is the deterministic, multi-scenario financial model that a Monte Carlo simulation stress-tests, with every revenue stream modeled explicitly per line of business rather than as a blended rate. It is the base case the stochastic simulation perturbs across a thousand paths.
A blended rate conceals which revenue stream is carrying the model and which is a drag. Model each stream separately or you will misstate both exposure and risk.
How it works
A revenue model is the structured, deterministic representation of all inflows and outflows, organized by individual line of business rather than collapsed into one blended rate. Each stream, whether creation fees, transaction fees, licensing revenue, or protocol-owned liquidity yield, is modeled separately with its own volume driver, fee rate, and cost allocation. The aggregate is the base-case projection the Monte Carlo then perturbs across a thousand randomized paths.
The model supports three scenario modes: conservative, base, and aggressive. One switch changes growth, fee assumptions, and cost allocations across all lines at once. Scenario switching is the deterministic layer of the analysis. The Monte Carlo adds the stochastic layer on top, generating a probability distribution over each scenario's outcomes.
Why it matters
Structuring by line of business is an auditing requirement as much as a modeling one. If creation fees are 80% of projected revenue and transaction fees 20%, a blended rate applied to total volume looks accurate in the base case but misstates risk. A collapse in creation volume is a catastrophic event, not a routine variance against an average.
Consider a protocol with creation fees, secondary-market transaction fees, and validator staking rewards. Creation fees front-load because they are charged once per asset. Transaction fees recur but track secondary market activity. Staking rewards depend on staked supply and emission. Blending all three is accurate only when they move in proportion, which protocols rarely do.
Common mistake
Building around the most optimistic scenario without calibrating the conservative case against real comparable data. Aggressive assumptions that are never tested against conservative inputs make the Monte Carlo a false-precision exercise: the distribution stays tight around the optimistic case because the model was built to show that case. The conservative scenario must be genuinely conservative, not a 10% haircut on an already optimistic projection.
