FirinWhen AI gives you confident nonsense.
Firin connects you with a verified human engineer who staked money on getting your answer right. No profiles, no credentials, no AI slop. Just the best solution, evaluated by a jury of peers with skin in the game.

Four properties that are impossible to fake — because they're enforced by cryptography and economic stake, not platform policy.
Verified human. No exceptions.
Every solver passed a zero-knowledge proof-of-personhood check. One biometric identity, one wallet — no bot farms, no AI submission pipelines, no agency fronts. When you get an answer on Firin, a real person wrote it.
The answer wins. Not the profile.
Solvers are wallet addresses. There are no credentials, no seniority titles, no follower counts, no LinkedIn bios. Eight anonymous peers judge the quality of the work itself. Pure meritocracy — your 20-year CV is irrelevant here; so is your age, your employer, and whether anyone has heard of you.
Your track record, quietly verifiable.
Every accepted submission writes to an on-chain reputation record anchored to your biometrically unique identity. It doesn't follow you around as a badge to farm or a score to game. It exists as proof, readable by anyone who wants to check — and meaningless to everyone who doesn't.
Everyone has money on the outcome.
Solvers stake to submit. Judges stake to vote. The minority side of a jury loses their stake. Nobody can phone it in — a careless answer or a lazy vote costs real money. The incentive to take the work seriously is baked into the protocol.
The floor is intentional. You're not paying for a guess — you're paying for a verified human who can't be a bot, can't run an alt account, and staked their own money on the quality of their answer. Serious problems deserve solvers who are taking it seriously.
The minimum also filters the request queue. Solvers on Firin are real engineers who could be billing elsewhere. A 1 SOL floor keeps the work worth their time — and keeps your request visible to them.
How it works.
Post a request
Describe your bug or the code you want reviewed. Lock a SOL bounty in an on-chain escrow. No payment processor, no middleman — the program holds it.
A verified solver submits
A human who passed proof-of-personhood submits their solution, staking SOL alongside it. The submission is encrypted — only you, the solver, and active judges can read it.
Eight judges reach consensus
Eight reputation-gated engineers each stake SOL to vote. Six of eight in agreement finalises immediately. The minority loses their stake. Careless judging costs money.
Payout settles on-chain
You review the consensus result and make the final call. On acceptance, the bounty releases directly to the solver's wallet in seconds. No invoice. No clearing period.
