Plain-language definitions of every term.
- Bonus pool
- Extra test USDC added to a race's pool from the rollover fund before betting locks. Winners share it. See The rollover bonus pool.
- Breed
- One of the four fly types: Direct, Cautious, Erratic or Bold. Each is a different set of tuned values. See The four breeds.
- Claim
- The transaction where you collect your winnings or a refund from a settled or cancelled race.
- Commit hash
- A fingerprint of the platform's secret salt (sha256 of the salt and the race id), published on-chain before betting opens, so the salt cannot be changed later.
- Commit-reveal
- A way of fixing a secret in advance (commit) and showing it afterwards (reveal), so everyone can check it was not changed.
- Devnet
- Solana's public practice network. Tokens on it have no value.
- Excitatory / inhibitory
- Neurons that make their targets more likely to fire (excitatory) or less likely (inhibitory).
- Faucet
- The button that gives you free test USDC and a little devnet SOL.
- Firing rate
- How often a neuron or group of neurons spikes. The brain panel shows it in Hz.
- Fly Sumo
- The platform sport where flies bump each other off a shrinking platform. See Fly Sumo.
- Hawk
- A predator that swoops over the lanes. Flies sense it as a looming shape and react.
- Interneuron
- A neuron in the middle layer of the brain, between senses and motor outputs.
- Lane race
- The main sport: four flies in four walled lanes, identical hazards in each.
- Lock slot
- The Solana slot after which no more bets are accepted. Fixed when the race is created.
- Lure
- Food or light that pulls a fly off its line. Distractible breeds are pulled harder.
- Mock / test USDC
- The no-value stand-in token used for betting on devnet. Not real USDC.
- Motor pool
- A group of output neurons whose firing rate sets turning or forward speed.
- Multiplier
- How many USDC come back per USDC staked if that fly wins at the current pools.
- Oracle (settlement oracle)
- The key that reveals the salt and posts the race result on-chain.
- Orchestrator
- The backend service that runs each race through create, lock, settle and close.
- Pari-mutuel
- A betting system where everyone's stakes form a pool and winners share it, with no bookmaker taking the other side.
- Pool
- All the test USDC bet on a race, split into one sub-pool per fly.
- Race card
- The public conditions of a race: distance, weather, track and hawks. See The race card.
- Rake
- The 6% fee taken from each pool: 5% house, 1% rollover.
- Ring-out
- In Fly Sumo, a fly bumped off the platform. It is unharmed and the fly that bumped it gets the credit.
- Rollover fund
- The program-owned vault that collects the 1% rollover and seeds bonus pools.
- Salt
- The platform's random secret for a race, committed before betting and revealed at settlement.
- Seed
- The number that makes a race unique, computed as sha256(salt, lock slot hash). Same seed, same race. See Fair play.
- Slot / slot hash
- Solana produces a new slot roughly every 0.4 seconds, each with a hash. The lock slot's hash is mixed into the seed.
- SOL
- Solana's native token. On devnet it pays transaction fees and has no value.
- Spiking neural network
- A brain model made of neurons that send discrete spikes, rather than smooth numbers.
- Tick
- One step of the simulation. The playback runs about 30 ticks per second.
- Tuned
- Set by hand and checked by simulation. FlySports breeds are tuned, not trained.
- Verify
- Re-running a settled race and checking it matches the on-chain record.
- Vault
- The token account that holds a race's stakes until they are paid out.
