The Jackpot
The jackpot is the headline prize. It is real, it is on chain, and it already pays.
How it grows
10% of every race pot feeds a single progressive pool. It carries from race to race and grows the longer it goes without popping. The bigger it gets, the more it pulls.
How it pays
At a race finish, a roll decides if the jackpot pops. When it pops:
- The entire pool goes to one winner. Not split. Not shared.
- The winner is drawn from the winning horse's top 40 holders, weighted by their holdings under the same 3% cap. More you hold, better your odds. A whale's odds are still capped at 3%.
- The pool resets to zero and starts building again.
So your odds scale with conviction, not with whale size.
It already happened
The first jackpot popped and paid 12.18 SOL to a single holder of the winning horse, in one transaction, verifiable on chain:

How the draw stays honest
The winner is computed deterministically from the race result and the frozen holder snapshot we publish. Same inputs always reproduce the same winner, so anyone can audit the draw after the fact. It is not a hidden roll behind a curtain.
The math, for the curious
Three formulas run the whole thing, and all of it is reproducible from the proof page.
1. It accrues. Every race, the jackpot slice of the pot is added to the pool, and the pool carries over until it pops.
pool_next = pool_now + (jackpot_share x race_pot) // jackpot_share = 10%
2. It gets more likely the longer it waits. This is the "progressive" part. At each race finish a chance decides if it pops. That chance starts low and rises with every race that passes without a hit (the drought), capped at 100%. A minimum pool floor stops it ever popping a tiny pot.
pop_chance = min( 100% , base + rise x races_since_last_pop )
it pops when: pool >= floor AND roll < pop_chance
A fat pool that has not paid in a while becomes very likely to pop. When it finally does, races_since_last_pop resets to 0 and the chance falls back down. The base, the rise and the floor are tunable parameters we announce.
3. The winner is a weighted draw. Among the winning horse's top 40 holders, your odds are your capped weight over the sum of all capped weights.
P(you win) = your_weight / sum(all_weights) // weight = min(your share, 3%)
The 3% cap is the whole anti whale trick. Hold 8% and hold 3% and your odds are identical, because both clamp to 3%. Holding more than 3% buys you no extra edge in the draw.
4. It is deterministic, so it is auditable. The draw does not use a hidden number. We derive a value in [0, 1) deterministically from the race result (the race id and the winning coin's mint), lay the eligible holders on that line in a fixed order with each holder's slice sized by their weight, and the winner is whoever's slice the value lands in.
roll = hash(race_id, winning_mint) -> a fixed value in [0, 1)
winner = the holder whose weighted slice contains roll
Same race result plus the same published snapshot always reproduce the same winner. Anyone can recompute it after the fact. Nothing behind a curtain.
