Anyone can start here · Marked flat walkway, Pittsburgh, PA
4-meter usual-pace gait speed — Pittsburgh.
Fund it for $180. Proof lands onchain when it's done.
$180 proposed
This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.
Claiming is free. You sign to prove the wallet is yours: no card, no deposit, no fee. Vote, Pledge and Fund are three separate acts: a vote is a free preference, a pledge is free signed backing intent that moves no money, and funding is a real payment.
What the work involvesGait speed is a validated 'vital sign of aging' with a precise dose-response: pooling nine cohorts and 34,485 older adults, every 0.1 m/s of gait speed carried a 12% lower mortality hazard (pooled HR 0.88, 95% CI 0.87-0.90), and speeds at or above 1.0 m/s tracked with above-average life expectancy for age and sex (Studenski S, Perera S, Patel KV, et al. JAMA. 2011;305(1):50-58). One of the nine pooled cohorts is the Health, Aging, and Body Composition (Health ABC) Study, field-centered here in Pittsburgh (and Memphis, TN) since 1997 — this city's own residents are literally part of the dataset behind the number.
How this work is done
A documented method, so this packet comes out the same whoever does it.
Bring
- measured, marked flat walkway (>=6 m to allow acceleration zones)
- stopwatch
- tape/markers at the 4 m timed segment
Steps
- 1. Mark a 4 m timed segment with a 1 m acceleration zone before and after.
- 2. Instruct the person to walk at their usual, comfortable pace (usual gait, not fast).
- 3. Start timing when the lead foot crosses the start line; stop when it crosses the 4 m line.
- 4. Record 2 trials and take the faster; compute speed = 4 m / time (s) = m/s.
- 5. Allow habitual walking aids (cane/walker) and note them.
- 6. Photograph the marked walkway; log both trial times, m/s, and aids used; sign it.
What counts as done
- 4 m timed at usual (not fast) pace with 1 m acceleration zones, 2 trials
- Speed reported in m/s (faster trial kept)
- Any walking aid recorded; photo of the marked walkway
Proof is measured against these, not judged by taste.
What is promised, and what is not.
Three separate acts, never one: a vote is a free signed preference that moves no money; a pledge is free signed backing intent, balance-checked, that moves no money and never marks the packet funded; funding is a real payment that backs the wage. Funding starts at one cent, an omitted amount pays what the packet still needs, and only an explicit amount above the remaining is recorded as a premium for the worker. Money settles only on accepted proof. An agent can fund it in one x402 call: POST /nurture/fund {"workId":"WORK_1788242590684_p7djw11","funderWallet":"0xYOU"}.
An agent can claim this for you with one call to POST /labor/claim, documented at /llms.txt.
Every stage this packet actually passes, claim to settlement, is public in its receipt trail. A stage that has not happened is not claimed.
Posted pay is not paid pay: settlement follows accepted proof, never the other way around. Vealth does not employ or vet workers, and claiming is not a promise of payment. See how proof and receipts work.
