Gov/en/Portal:R&D/Innovations:Bonding Curve

💡 In simple words: Think of the very first people who chip in to build something new: they take the biggest chance, so they get the best reward. The Bonding Curve is the clear, public math rule that gives early supporters more Rewards per franc, with no guessing and no secret deals.

The bonding curve is the core algorithm that converts funding contributions into Rewards. It is a transparent, defined algorithm, not frozen (it can be updated through Open Calls with mathematical experts). Updates apply prospectively only: they never reduce rights already attributed at the moment of a contribution, but consistent and publicly documented. It ensures that early funders are rewarded for taking on the highest risk.

The bonding curve ensures early funders receive more Rewards per CHF, recognizing the risk they take when the platform is unproven.

How the Bonding Curve Works

The bonding curve relates the current funding reserve level to the Rewards generated per CHF contributed. The key principle: as the reserve grows, each CHF generates fewer Rewards. This rewards early participants and creates a natural, non-speculative incentive to fund early.

The Mathematical Formula

Rewards(CHF) = CHF × multiplier(R) Where multiplier(R) is a decreasing function of Reserve R: multiplier(R) = M_max × e^(-k × R) M_max = maximum multiplier (at R=0, e.g. ×100) k = decay constant (determines how fast multiplier drops) R = current reserve level (total CHF in fund) e = Euler's number (≈ 2.718...) Example at R=0 (first funder): CHF 1 → 100 Rewards Example at R=50,000 CHF (mid-stage): CHF 1 → ~30 Rewards Example at R=500,000 CHF (growth stage): CHF 1 → ~5 to 8 Rewards

⚠️ This calculation will be discussed in Open Calls by mathematical experts. The exact constants (M_max, k) are subject to community review and may be adjusted through the Open Call process.

Why a Bonding Curve?

The bonding curve solves a fundamental bootstrapping problem: how do you reward early funders fairly without creating speculation or securities law issues?

Early funders take the highest risk (platform unproven) → receive highest multiplier
Later funders take less risk (platform established) → receive lower multiplier
No external market price needed: the algorithm is self-contained
No speculation: Rewards are not tradeable on open markets
Transparent: everyone can see the curve and calculate their Rewards

Relation to Rewards and Karma tokens

The bonding curve determines the total Rewards generated. The Need-Driven Funding then determines how those Rewards are split between personal Rewards (P2) and the community pool. The bonding curve itself does not determine the Cash/Karma-token ratio: that is the Need-Driven Funding mechanism's job.

Transparency Commitment

WikiDeal commits to publishing the full bonding curve formula, constants, and historical data. Community members can verify their Reward calculations independently. The formula is defined, not opaque, and any changes must go through an Open Call process with mathematical expert review.
