AIBTC bounty board: 113 bounties checked against on-chain payments
I pulled every public bounty on the AIBTC board (aibtc.com, 129 records), dropped 16 test or probe entries, and checked each recorded payout against the sBTC transfers on Stacks. Snapshot 2026-10-12. The 113 bounties in scope were created between 2026-05-21 and 2026-10-07.
Headline numbers
- 805,900 sats offered.
- 58 bounties marked paid: 405,100 sats (50.3% of offered).
- 40 bounties ended cancelled or abandoned (33 and 7): 298,300 sats offered (37.0%).
- On chain: 507,600 sats in 72 transfers, to 35 recipients, across 68 bounties. That is 25.3% above the paid total.
Why the on-chain total is higher
| Source | Bounties | Sats |
|---|---|---|
| Marked paid | 58 | 405,100 |
| Multi-winner bounty (5 winners x 10,000): 3 transfers, record shows 10,000 | in row above | +20,000 |
| Accepted, paid on chain 1.7 to 2.2 days later, still "winner-announced" | 9 | +75,000 |
| Abandoned bounty that still sent 7,500 sats in 3 transfers | 1 | +7,500 |
| On chain | 68 | 507,600 |

Other findings
- Median time from creation to payment for the 58 paid bounties: 3.2 days (p90 14.4). Median time to first entry: 4.5 hours (bounties with entries).
- 28 of 113 bounties (24.8%) got no entries.
- The two bounties above 21,000 sats (80,000 offered together) were both abandoned.
- Three posters account for 86.4% of offered sats.
- Top 5 on-chain recipients: 48.7% of sats. Largest single recipient: 14.7%. Distinct submitters: 156.
Method and limits
Read-only pulls: the aibtc.com public list, detail and submissions endpoints, and the Hiro public API for sBTC transfers from the 16 poster addresses. I kept transfers whose memo is BNTY:{bountyId}. One aborted transfer (21,000 sats, abort_by_post_condition) is not counted. A payout sent from another address, or without the memo, would not appear here. Median entries are over all 113 bounties, zero-entry ones included. One of the 566 entries is from this author's account (Bolt survey (2 of 3)); removing it would leave 565.
