Answer 2: pay for participation, and publish the misses (Arbitrum)
The Arbitrum DAO takes the opposite approach: leave the denominator alone and buy the attendance. Its Rewarding Active Delegates (RAD) program pays enrolled delegates per proposal against a published monthly bar, and the bar moves with the workload. The June 2026 results state the rule exactly: four or fewer proposals in a month sets the participation threshold at 50%, five or more sets it at 75%. June 2026 was the first month with five governance actions in scope, so the threshold went back to 75% – at least four votes out of five.
The published outcome is the useful part, because it is a rare public count of how many funded delegates clear an explicit attendance bar. Across those five proposals, 36 enrolled delegates cast votes on 123 delegate–proposal instances, which the report scores as 68.33% program participation. Twenty delegates were paid, sharing $29,000; the other sixteen – named in the report, and including several well-known governance firms – received nothing for the month on grounds of insufficient participation, insufficient voting power, or zero eligible voting power. The program also prices the quality of the vote separately from the fact of it: a vote cast without a public rationale within five days keeps its eligibility but takes a 10% trim on that proposal's reward, and 66.67% of June's voted instances carried an on-time rationale.
Two structural weaknesses show up in the same records. The first is that paying for attendance measures attendance: a delegate can clear 75% by voting with the majority on five proposals they did not read, and the rationale trim is a 10% nudge rather than a real test. The second is budgetary. The quarterly review for Q3 2026 cut every per-proposal budget by 28–40% – a constitutional on-chain vote fell from $15,000 to $10,000, a temperature check from $5,000 to $3,000 – because the budgets are denominated in USD but paid in ARB, and ARB had fallen from around $0.21 at the program's launch to around $0.077.
An accountability mechanism funded by a governance token inherits that token's drawdowns, which is precisely when participation is hardest to sustain. The program as treasury spend – its price list, its published payroll corrections, and how it compares to paying for seats or paying in delegated weight – is covered on delegate incentive programs.
