Tasknull turns a completed bounty into a cryptographic receipt. Reviewers confirm the work is real and the claim can't be spent twice — without ever learning which wallet did it.
Either your wallet is attached to the payout for everyone to trace, or your contribution can't be trusted. Tasknull adds a third path: provable completion, unlinkable identity.
Every claim carries a proof that the bounty's acceptance criteria were met. Reviewers check the math, not your reputation.
The payout wallet and the proof are cryptographically separated. A verifier learns "valid hunter," never which hunter.
Each claim emits a one-way nullifier. Reuse the same solution twice and the second nullifier collides — the chain rejects it.
Three steps, one CLI. The signing happens entirely on your machine — no coordinator, no custodian, no account.
Hash your work against the bounty's criteria and publish the commitment. Nothing about your identity leaves the machine.
$ tasknull commit --bounty zk-audit-114
The CLI derives a nullifier from your secret and signs the completion proof. Reveal it whenever you're ready to claim.
$ tasknull prove --reveal ./solution
Anyone can verify the proof and nullifier. Once it checks out, the reward releases to a fresh address you control.
$ tasknull claim --to 0x7E57…4A21
Each tile simulates a nullifier — a one-way mark used to prevent a bounty claim from being spent twice. Click one to test the interaction locally; no Arc transaction is submitted.
Claim a disclosure bounty without tying the patch — or the payout — to your real name or employer.
Build a track record through stable nullifiers while keeping every wallet address single-use and clean.
Let a treasury reward completed work on-chain without a public map of who did what for whom.
Planned for Arc Testnet. Reward pools are designed to use $TNULL and release to the payout address carried by a valid proof. The v0.1 flow remains a local reference until the Arc contracts launch.
