EcoSats Specification

Version 1.0 – November 2025
“1 sat + 1 real-world sufficiency unit”

1. Core Definition

EcoSat (ES) is a dual-peg digital voucher issued by a local commons council and redeemable in two layers:

Layer Peg Symbol
A. Bitcoin Layer 1 ES = 1 satoshi (0.00000001 BTC) 1 Ƶ
B. Sufficiency Layer 1 ES = 1 verified local sufficiency unit (see §3) 1 ☀

Redemption rule: 1 ES = either 1 sat or 1 sufficiency unit, never both.
This prevents double-spending while allowing exit liquidity.

2. Issuance & Backing

Mechanism Details
Issuer Commons Council (7–12 elected stewards, 6-month rotating mandate)
Backing Vault 3-of-5 multisig on Bitcoin mainnet (BIP-86 Taproot)
Initial Collateral 10 % in BTC, 90 % in pre-verified sufficiency units (see §3)
Max Supply Capped at 10 % of local annual labor hours (e.g., 100 k hours → 10 M ES max)
Burn-on-Exit When redeemed for sats, the sufficiency unit is marked spent in the local ledger and the ES is burned (sent to OP_RETURN).

3. Sufficiency Unit Catalog (Examples)

Code Unit Verification Method Example Redeem
☀1 1 kWh excess renewable (curtailed or spilled) Smart meter + oracle (e.g., FlexiDAO) Charge e-bike at co-op station
⚒1 1 hour human care/repair Time-bank app + photo proof Bike repair at the fix-it café
🌱1 1 kg regenerative compost Weigh-in + QR seal Collect at community garden
🪴1 1 m² permaculture bed (1-year lease) GPS polygon + annual audit Grow food on commons land

New units added by Council vote + 30-day community objection window.

4. Technical Stack

Layer Tool Reason
Custody Bitcoin Core + Taproot multisig Immutable, auditable
Sufficiency Ledger Hyperledger Fabric (permissioned) Local privacy + verifiable claims
User Wallet Minibits (open-source, Cashu ecash) Chaumian mint on Lightning; no KYC
Oracle OpenEMS + DLCs (for energy) Dispute-free proof of excess kWh
Bridge Atomic swap script (sats ↔ ES) Trustless exit

5. Flow Examples

A. Earn (Local Loop)

  1. Alice installs 2 kW solar → 300 kWh curtailed in summer.
  2. Oracle signs: ☀300.
  3. Mint issues 300 ES to Alice’s Minibits wallet.
  4. Alice spends 150 ES at the repair café (⚒150). Café now holds ES.

B. Exit (Global Bridge)

  1. Café wants to buy spare parts online.
  2. Sends 100 ES to Council mint.
  3. Mint burns 100 ES, releases 100 sats to Café’s LN address.
  4. Sufficiency units (☀100) marked spent in local ledger.

6. Anti-Speculation Mechanisms

Rule Effect
Demurrage –2 % per month on balances > 1 000 ES
HODL Lock Balances > 5 000 ES auto-lock for 1 year
Redemption Cap Max 10 % of total ES redeemable for BTC per month

7. Governance (One-Pager)

Commons Council (3-of-5 multisig + 7 human stewards)
       │
       ├── Issues ES (mint)
       ├── Burns ES on BTC exit
       ├── Adds new sufficiency units (vote)
       └── Emergency freeze (75 % vote, 72 h max)

Audit: Quarterly open-source proof-of-reserves (BTC + sufficiency ledger).

8. Launch Checklist (3 Months)

Week Task
1–2 Form Council, draft sufficiency catalog
3–4 Deploy multisig + Hyperledger node
5–6 Onboard 10 solar households (oracle integration)
7–8 Seed mint with 1 BTC + 10 k verified ⚒ hours
9–12 Public mint launch + wallet QR stickers in village

9. One-Line Tagline

EcoSats: Bitcoin-backed sufficiency—spend local, exit global, never inflate.
