BABY paired vs efficiency
Each row is a different BABY amount paired against the same BTC, shown as a % of the optimal (20,000 × BTC). Weight caps at your BTC amount — extra BABY past 100% adds nothing further. Your selected value is highlighted.

The min() that decides who gets the bonus
Babylon's base BTC and BABY staking already pay their own yields. Co-staking is a third, separate pot — funded by 2.35% of annual BABY inflation — reserved for stakers who pair both assets from the same address in the right ratio. The mechanism is deliberately simple and deliberately punishing for mismatched pairs: your co-staking weight is w = min(BABY staked ÷ 20,000, BTC staked). Every 20,000 BABY you stake unlocks 1 BTC-equivalent of weight, but the moment your BABY runs out relative to your BTC, the min() clamps your weight at whatever BABY can cover — the rest of your BTC sits there, fully staked, fully exposed to finality-provider slashing risk, earning zero co-staking bonus. There is no partial credit curve and no soft cap; it is a hard ratio gate. This calculator prices that gate directly: your exact efficiency percentage, how much BTC weight you're leaving on the table, and — using your own assumptions for how contested the pool is — roughly what the bonus is worth in dollars. If you haven't already, size the base BABY yield itself with the Babylon BTC staking calculator, or compare the whole native-BTC-staking path against running infrastructure yourself with the validateur vs calculateur de pool.
Les mathématiques
Laisser B be BTC staked to an active finality provider and Y be BABY staked from the same address. The protocol's co-staking factor is a fixed constant R = 20,000 — every 20,000 BABY makes 1 BTC eligible. Your co-staking weight est w = min(Y⁄R, B), expressed in BTC-equivalent units. Your efficiency est w⁄B × 100: 100% means every BTC you staked is earning the bonus, 50% means half of it is dead weight. The BABY amount needed for full efficiency is simply B × R; any BABY beyond that is not wasted (it still earns Babylon's normal BABY staking yield) but adds nothing further to w, since the min() is already pinned at B.
Rewards are distributed as your reward = pool × (w ⁄ total weight of all co-stakers). Ce calculateur vous demande d'estimer les deux éléments que vous ne pouvez pas rechercher à l'avance sur la chaîne – le poids combiné de tous les autres co-stakers et la valeur annuelle en USD du pool – afin qu'il puisse transformer votre part en une récompense annuelle projetée et un TAEG implicite sur la valeur en dollars de votre BTC misé. Étant donné que la participation à l'échelle du réseau n'est pas fixée par le protocole, considérez cette estimation de récompense comme une vérification de sensibilité selon vos hypothèses déclarées, et non comme un nombre garanti ; le pourcentage d’efficacité au-dessus, en revanche, est exact et découle directement de la formule publiée, indépendamment de l’enjeu des autres.
