the five petals
this is the heart of kobai. every coin is born with a flower, and every coin that blooms burns it — one petal a day.
the flower
at launch, 5% of the coin's supply is locked inside the coin's own contract. this is the flower.
- nobody owns it. not the creator, not the kobai team, not a multisig.
- it cannot be sold, transferred, lent or voted with.
- the contract can do exactly one thing with it: burn it, on schedule, after the bloom.
the flower has 5 petals. each petal is 1% of the initial supply.
the burn schedule
the moment a coin blooms, its clock starts. every 24 hours, one petal burns: 1% of the initial supply is sent to the burn address and removed from the supply forever.
| time after bloom | petals burned | supply left |
|---|---|---|
| 0 h | 0 | 100% |
| 24 h | 1 | 99% |
| 48 h | 2 | 98% |
| 72 h | 3 | 97% |
| 96 h | 4 | 96% |
| 120 h | 5 | 95% |
petals only — the flame fee burns more on top.
exact formulas
petals burned at time t
n(t) = min( 5, max( 0, ⌊ (t − t_bloom) ÷ 24h ⌋ ) )
supply at time t
S(t) = S₀ × (1 − 1% × n(t)) − B_flame(t)
your share at time t (you hold b tokens)
share(t) = b ÷ S(t)
share growth after the full bloom, flame fee ignored
S₀is the initial supply,t_bloomthe bloom block's timestamp.B_flame(t)is everything the flame fee has bought back and burned so far.- the burn uses the initial supply, so every petal is exactly the same size.
a worked example
a coin with 1,000,000,000 tokens blooms. you hold 10,000,000. you never buy or sell. here is your share, day by day.
| day | supply | your share | vs bloom |
|---|---|---|---|
| bloom | 1,000,000,000 | 1.0000% | — |
| day 1 | 990,000,000 | 1.0101% | +1.01% |
| day 2 | 980,000,000 | 1.0204% | +2.04% |
| day 3 | 970,000,000 | 1.0309% | +3.09% |
| day 4 | 960,000,000 | 1.0417% | +4.17% |
| day 5 | 950,000,000 | 1.0526% | +5.26% |
the holder never traded. the supply shrank under them. that is what lighter every day means.
who triggers a burn
the schedule is enforced by the contract, so a petal can only burn when its time has come — never early, never twice. the burn function is public: kobai runs a keeper that calls it on time, and anyone else can call it too if the keeper is late. any trade on the coin after the deadline also burns the pending petals first. in practice, petals burn on the minute.
what you see on the site
everywhere a blooming coin appears, its five-petal meter replaces a progress bar:
- glossy orchid petals are still on the flower,
- the flickering one is the next to burn,
- grey ash outlines have burned.
the coin page also shows a live countdown to the next petal and a burn history you can check against the explorer.
