Most tokens reward whoever turns up with the most money. Kairo doesn't. It rewards the wallets that have actually used Solana — the ones with real history, real trades, real conviction.

When you connect, Kairo reads your public on-chain history and turns it into a single number: your hashrate. The higher it is, the faster you mine $KAIRO. No GPUs, no ASICs, no staking your capital — your past activity is the rig.

It's “proof of activity”: you're not racing to win a block, you're sharing every block with everyone else, in proportion to your hashrate.

Your score is built from four things about your wallet, all read straight from the chain:

• Age — how long your wallet has been around
• Trades — how many real swaps you've made (dust under $10 doesn't count)
• Volume — the USD size of those swaps
• Hold time — how long you actually hold what you buy

Each one is capped and weighted, then mapped onto a hashrate between 100 and 10,000. A brand-new wallet still scores something; a long-lived, high-conviction trader lands near the top. The cap matters — it stops whales from running away with the whole pool.

A few deliberate choices keep it honest: trade count and volume scale logarithmically (so wash-trading hits a wall fast), only tokens you actually bought count toward hold time (airdrops don't), and we use the median hold, not the average, so one diamond-hand bag can't carry you.

The scoring is open-source and deterministic — same wallet, same inputs, same number, every time. Anyone can recompute yours and check it. Try it on the calculator.

$KAIRO is front-loaded: it pays out fast at the start and then tapers toward the cap. Day one mints 300,000 $KAIRO to the whole network; that eases to around 50,000 a day by day ten, then rides down from there (base half-life 1 year) — about 97% mined by year 5.

• Day 1 — ~300,000 / day
• Day 10 — ~50,000 / day
• Year 1 — ~18,000 / day (≈52% mined)
• Year 3 — ~4,500 / day (≈88% mined)

It's the sum of two halving curves — a sharp early “spike” plus a slow “base” — which together approach but never quite reach the 21,000,000 ceiling. Earliest miners earn the most, but there's still meaningful $KAIRO left to mine for a very long time.

Whatever the network emits in a given moment is split across all active miners by hashrate share. More miners (or a bigger network hashrate) means a thinner slice each.

Once you're in, you mine continuously — nothing to keep open, no process to run. The program tracks everyone's hashrate and credits your share every moment, using the same accumulator pattern staking contracts use (so it costs the same whether there are 10 miners or 10,000).

But mining isn't set-and-forget. Your hashrate halves every 36 hours — so to keep earning at full power you top off (a small 0.02 SOL fee) to reset it to your full score. Let it slide and you simply mine less; top off and you're back to 100%. It keeps Kairo for people who actually stick around, and lets abandoned wallets fade out instead of diluting everyone forever.

Your rewards pile up on-chain until you claim — mints the $KAIRO straight to your wallet, whenever you like. Accrued rewards never expire; only your hashrate decays.

Costs: a one-time 0.1 SOL entry fee, then 0.02 SOLper top-off to stay at full hashrate. Anyone can also “poke” a dormant miner to apply its decay — that's how ghosts get pruned from the pool.

• Standard SPL token, 6 decimals
• Hard cap — 21,000,000, enforced on-chain
• 1,000,000 at genesis (the launch supply); everything else is mined
• Mint authority is held by the program — no one can mint outside the rules

The launch supply seeds a Dynamic Bonding Curve so $KAIRO is tradeable from day one. After that, the only new $KAIRO that can ever exist is what gets mined — and that's bounded by the curve above and capped forever at 21M.

Mining isn't free. Starting a rig costs 0.1 SOL, and keeping your hashrate at full costs a 0.02 SOL top-off every so often. Those fees don't just disappear — they pool in the treasury and get put to work.

On a schedule, an automated keeper checks the treasury balance. A fixed reserve always stays put. Anything above that is split in two: half funds operations, and the other half is used to buy $KAIRO back off the open market (through Jupiter) and immediately burn it — gone, supply permanently reduced.

So the more the network is used, the more fees accumulate, the more $KAIRO gets bought and burned. Activity on the chain becomes constant, structural deflation on the token. That's the flywheel: usage → fees → buybacks → burns → tighter supply.

Every buyback and burn is on-chain and verifiable. The running totals — SOL spent buying back and $KAIRO destroyed — are shown live on the home page.

Short version: connecting can't lose you anything. Kairo is fully non-custodial. Connecting only lets the site read your public address and ask you to sign transactions you can see and reject. We can never move, spend, or touch your assets.

Mining is a single transaction you approve in your own wallet — the 0.1 SOL fee and nothing else. The program mints rewards through its own authority based on the math; that minting can't be triggered to exceed the cap or sent anywhere but the claimer.

Your score is signed off-chain and verified on-chain, so you can't fake a higher number — and even if our signing key were ever compromised, the worst case is a wrong hashrate (bounded by the cap), never stolen funds or extra supply.

Everything — the program, the scorer, and this site — is open source. Read it, run it, check it: github.com/KairoMine/kairo.

Do I have to keep my computer on to mine?

No. Once you've initialized, you mine 24/7 on-chain. Close the tab — your rewards keep accruing.

Why is my score lower than I expected?

Usually hold time. If you trade fast and flip quickly, that factor stays low by design — Kairo rewards conviction. Trades and volume also flatten out past their caps, so being extremely active doesn't push the number much higher.

Does my hashrate really halve every 36 hours?

Yes — your effective hashrate halves every 36h until you top off (0.02 SOL), which resets it to your full score. Your base score itself doesn't change; only the effective rate decays. It's what keeps mining tied to staying active.

What does it cost to mine?

A one-time 0.1 SOL to start (anti-spam), then 0.02 SOLper top-off whenever you want to restore full hashrate. Skip top-offs and you just earn less — you're never forced to pay.

Is this live on mainnet?

The program is deployed and verified on mainnet — anyone can confirm the on-chain bytecode matches this repo. Mining unlocks when the $KAIRO mint authority is handed to the program at token launch; until then your hashrate preview is live and scored from real mainnet history.
