Latest revision as of 00:38, 19 August 2026

💡 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.

🎯 In 20 seconds (scientific summary): The Bonding Curve is a transparent algorithm intended to convert funding support into Rewards: the earlier the support, the higher the multiplier (up to ×100, around ×30 at mid-stage). It is non-speculative, publicly documented, and revisable prospectively through Open Calls with mathematical experts.

Every new platform faces the same bootstrapping question: why would anyone support a project before it has proven itself? The first supporters carry the most uncertainty, so fairness suggests they should receive the most in return. The Bonding Curve is WikiDeal's answer: a public, verifiable formula that anyone can check, designed so that trust comes from transparency rather than from promises.

How the Bonding Curve is intended to work

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

For a supporter, the experience is simple: Anna supports with CHF 100 when the reserve is nearly empty and would receive far more Rewards per franc than Ben, who supports the same amount a year later when the platform is established. Both can verify their calculation themselves, because the formula is public.

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 the multiplier drops); R = current reserve level (total CHF in fund); e = Euler's number (≈ 2.718...). Example at R=0 (first supporter): 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 is intended to 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 Calls process. Updates would apply prospectively only: they would never reduce rights already attributed at the moment of a support.

Why a bonding curve?

The bonding curve addresses a fundamental bootstrapping problem: how to reward early supporters fairly without creating speculation or securities-law issues.

Early supporters take the highest risk (platform unproven) → highest multiplier
Later supporters take less risk (platform established) → 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

Who does what

Supporters choose when and how much to support, and can verify their Rewards independently.
Mathematical experts review the constants through Open Calls.
The community oversees any change to the formula, which keeps governance in citizens' hands rather than in a closed boardroom.

Relation to Rewards and Karma tokens

The bonding curve determines the total Rewards generated. The Need-Driven Funding mechanism and the donor's own choice at donation time then determine how many of those Rewards the donor keeps and how much is left to the project as pure support (see the Rewards FAQ for the formulas currently proposed). Karma tokens are a separate, non-convertible form of Rewards, documented on their own page; the bonding curve does not determine them.

Transparency commitment

WikiDeal intends to publish the full bonding curve formula, constants, and historical data. Community members would be able to verify their Reward calculations independently. The formula is defined, not opaque, and any change would go through an Open Call process with mathematical expert review. This reflects WikiDeal's broader aims of transparency, lower cost, flexibility and citizen participation.
