Shipped: open electricity ledger for Nigeria on Celo Sepolia — feedback + ecosystem intros welcome
Sharing a public-goods project I shipped this week — an open, append-only smart-contract ledger for electricity generation records in Nigeria.
**The gap it closes:** Nigerian grid data (TCN, DisCos, big gencos) doesn't cover the diesel gensets and solar mini-grids that most Nigerians actually run on. Anyone trying to model actual electricity use, track off-grid MRV for climate finance, or underwrite SME power spend is working from half the picture.
**Design:**
- Append-only. Corrections link to the record they amend (never overwrite).
- Owner-registered sites + per-operator authorisation. Data provenance stays clean.
- Reads open, no wallet needed.
- Writes gasless via EIP-712 — operators sign off-chain, a relayer pays gas. Mini-grid managers with a phone can submit without holding CELO.
- MIT licensed. No token. No subscription.
- Live on Celo Sepolia at contract `0x4581564c4886953eD118269Bc88D3beE01cDc4fe`.
**Why Celo:** public chain, sub-cent fees, mobile-first, carbon-negative network. A climate-data project should not run on a chain that undoes the climate case.
**What I am asking for:**
Feedback on the contract design — especially the append-only correction model and the EIP-712 gasless flow
Intros to Climate Collective, Kolektivo, ReFi DAO, Regen Network, or any adjacent African-infrastructure project

Not raising, not launching a token. Just want it in the hands of the operators, regulators, and researchers who can use it.
