How to Participate

1. Pick a bounty from the table above
2. Comment on that issue to claim it (first-come, first-served for 2 weeks, then opens up)
3. Submit your PR or report
4. Earn RTC + climb the Contributor Ladder

Season Rules

• Quality over speed — thorough work earns more than rushed submissions
• Partial credit available — if you find something valuable but don't complete the full bounty, you still earn proportional RTC
• Collaboration encouraged — teams can split bounties (declare upfront)
• All merged PRs from this season count toward your Contributor Ladder tier

Seasons give focus. Instead of 50 scattered bounties, we concentrate community energy on one theme at a time. This is how we build a secure, battle-tested blockchain.

我可以来做这个（如果确实是有偿/悬赏任务的话）。为了对齐预期并尽快开始，麻烦确认几件事：

1. 悬赏/报酬金额与结算方式（是 GitHub Sponsors / Bounty 平台 / 直接转账？）
2. 验收标准（通过哪些测试/功能点算完成？）
3. 期望交付形式（PR 合并即算？还是需要 release/文档/示例？）

你补充以上信息后，我可以先给出实现方案与预计工期，然后直接开 PR 推进。

@Fred-Zhang83 — This is an automated bounty-hunting template comment. These bounties require actual deliverables (code, content, testing), not claim requests. Please read the bounty requirements and submit actual work.

[nicepopo86-lang]

I can take one of the Season 1 security bounties next.\n\nI’ve already started/advanced the other two top candidates (#21, #89 in their repos).\nFor #400, please confirm the current active Rustchain issue IDs for Season 1 (the table links appear to reference old/closed IDs), and I will pick the first unassigned medium bounty immediately and submit a PR.

🚨 New Hardening Bounty Trio Is Live

We just opened three focused security/reliability bounties with reduced payouts and strict acceptance criteria:

1. #474 — Epoch Determinism Simulator + Cross-Node Replay (113 RTC)
2. #475 — Attestation Fuzz Harness + Crash Regression Corpus (98 RTC)
3. #476 — Sybil/Farming Risk Scorer for Bounty Claims (83 RTC)

Total pool: 294 RTC

These are designed for high-signal contributors who can ship runnable code, tests, and reproducible verification artifacts.

If you claim, include:

• your wallet/miner ID
• your implementation plan
• expected delivery timeline

First high-quality valid submission per bounty wins.

[Scottcjn]

Status update on the new hardening trio:

• [BOUNTY] Epoch Determinism Simulator + Cross-Node Replay (113 RTC) #474 is still open. No fully qualified claimant yet.
• [BOUNTY] Attestation Fuzz Harness + Crash Regression Corpus (98 RTC) #475 has an early claim, but maintainer is awaiting the full required template details.
• [BOUNTY] Sybil/Farming Risk Scorer for Bounty Claims (83 RTC) #476 has an early claim, but maintainer is awaiting the full required template details.

Reminder: a claim is not considered secure unless the claimant posts wallet/miner ID, implementation plan, test plan, and ETA. Claim window rules remain in effect.

#400 진행 상태 동기화 요청
오너님이 2026-03-01 기준으로 공유해주신 Hardening Trio(#474~#476) 업데이트를 반영해, 우리 claim(#400 API 검증/인증 하드닝 항목)과 정합성 체크 중입니다.

확인 요청드립니다:

1. 현재 #400에서 추가/변경된 필수 요건이 있다면 (범위·검증 기준·산출물 형식) 우선순위순으로 알려주실 수 있을까요?
2. 기존 claim에서 빠진 항목이 있다면 어디가 부족한지 1차로 지정해주시면 바로 보완하겠습니다.

오너님 기준대로 즉시 트래킹/산출물 정렬 후 업데이트하겠습니다.
