Mine on Sunlight.
Build on Solar.
The world's first solar-powered blockchain platform. A $7 miner. A small solar panel. A recycled 18650 battery. That's all it takes to join a network that proves not all tech needs to be dirty to work and scale. Every watt is measured, on-chain, forever.
Powered by the Sun
Bitcoin burns more electricity than Argentina. SolarCoins runs an entire mining network on a single solar panel. Not all technology needs to be dirty to work — and SolarCoins proves it can scale clean.
Solar-Powered Mining
Every miner draws just 1.2 watts — less than a single LED bulb. A $12 solar panel (5W) powers a miner 24/7 through a recycled 18650 lithium cell pulled from an old laptop battery. The sun charges the cell during the day, the cell mines through the night. Zero grid. Zero carbon. Zero compromise.
Recycled Battery Power
SolarCoins miners run on salvaged 18650 cells — the same batteries inside old laptops and power tools that would otherwise end up in landfills. A single 2600mAh cell powers a miner for 8+ hours overnight. A TP4056 charge controller and a small panel keep it topped off. This isn't theoretical sustainability. It's a $2 battery, a $0.50 charger, and sunlight.
Proof on Every Share
Every share submitted to the network includes real hardware-measured data — voltage from ADC sensors, chip temperature, WiFi signal strength, power draw in milliwatts. This isn't an estimate from a model. It's a reading from a physical sensor, timestamped and recorded on-chain. Cryptographic proof of efficiency that no other blockchain can provide.
Clean Tech Scales.
The crypto industry tells you that proof-of-work requires warehouses full of ASICs and megawatts of coal power. That's a choice, not a law of physics. SolarCoins chose differently. We designed the hardware, the power system, and the protocol as one integrated system — and proved that a blockchain can run on milliwatts instead of megawatts. Ten miners. One solar panel. A handful of recycled batteries. A fully functional blockchain. If tech doesn't need to be dirty, why is it?

Build on SolarCoins
SolarCoins isn't just a currency — it's a platform. Create custom tokens, build solar-powered apps, and launch green economy services on a chain that verifiably runs on sunlight.
Token Factory
Create your own token for 100 SOLAR/1. Define your supply cap, mint tokens, and enable transfers — all through the REST API. Your token inherits SolarCoins's green infrastructure by default.
Green Verification
Every token on SolarCoins can claim what no token on Ethereum or Solana can: it was mined, minted, and transferred using zero grid electricity. The energy proof is on-chain. Verify it yourself.
IoT Data Layer
ESP32 sensors can mine SOLAR/1 to pay for network access and publish data to the chain — temperature, humidity, solar output. A self-funding IoT network powered by the sun.
REST API
Full programmatic access. Create tokens, check balances, submit transactions, query the chain. Build dApps, dashboards, bots, and integrations with simple HTTP calls.
# Create a green energy token on SolarCoins curl -X POST https://api.solarcoins.net/token/create \ -H "Content-Type: application/json" \ -d '{"symbol": "GWATT", "name": "GreenWatt", "max_supply": 1000000, "username": "you", "password": "pass", "description": "1 token = 1 kWh of verified solar energy"}' # Mint tokens to a user curl -X POST https://api.solarcoins.net/token/mint \ -d '{"symbol": "GWATT", "amount": 500, "recipient": "alice", "username": "you"}' # Check all balances curl https://api.solarcoins.net/token/GWATT/balances
Live Market
Trade tokens minted on the SolarCoins network against SOLAR/1. Full price-time-priority order book with market, limit, GTC, IOC, and FOK orders. Submit, match, and settle — all on-chain, all auditable.
The Network
Right now, ESP32 miners on three continents are burning real watts to sign blocks on SOLAR/1. Every block below was minted by hardware you can buy for the price of dinner. No promises. No staking. Real silicon, real electricity, real receipts.
Don't launch a chain. Mint on one that's already mining.
SOLAR/1 isn't a whitepaper. It's running right now — block loading…, with … miners drawing real watts on three power supplies. You can verify every share on the explorer.
The chain comes with a token factory built in. Mint your own asset — a renewable energy credit, a grid stability token, a community currency — and inherit this entire mining fleet as the security layer underneath it. Zero gas. Zero ICO. Zero permission. Your token gets the watts, the hashrate, the public ledger, and the explorer — for free.
$5 of ESP32 hardware. One line of curl POST /token/create. You're now issuing a green-verified asset on a chain that's literally drawing power from the sun. That's the moat.
