EcoCycle is a verified receipt for Lagos's waste economy.

  Lagos generates roughly 13,000 tonnes of waste a day, and the recoverable part is already moving: households separate it, informal
  collectors carry it, and processors buy it. What nobody has is a shared, checkable record of what moved, what it actually weighed,
  and who is owed for it. The household is told a weight it cannot verify. The collector is paid on a figure declared at a gate, with
  no way to prove an honest track record. The processor buys loads of unknown origin and absorbs the cost of contamination it cannot
  trace.

  EcoCycle closes that gap by keeping three weights permanently apart — expected_kg (the household's estimate), collected_kg (the
  agent's declaration), and verified_kg (the facility scale) — and settling money only on the verified weight. Every batch travels a
  guarded state machine from doorstep request, through marketplace claim, agent collection, facility inspection, and processing,
  leaving an audited event at every step. Settlement is computed by one service from a server-side rate table, split 60/40 between
  household and agent, and written to an append-only, idempotent ledger — so a balance is always reproducible and can never be paid
  twice.

  The result is one record read identically by a household on a phone, a collector on a round, an inspector at a bench, and anyone
  scanning the QR tag on a bag. Households get a receipt they can check, honest collectors get a provable reputation, facilities get
  feedstock with known provenance, and the city gets diversion it can evidence.
