The total supply of SolarCoin in circulation will be approximately §98.1 billion over the next 40 years. This is fully documented and is comprised of the following:
- Public Staking and Mining: ~§100 million (0.1%) of which §33.3 Million are publicly mined using scrypt PoW until such time that the Proof of Stake algorithm is implemented (currently scheduled to take place at Block 357,520). All publicly mined SolarCoins represent historically generated and unclaimed solar electricity. From block 357,520 forward, the only new supply of coins will come from the 1% staking interest that is built into the PoS model.
- The Generator Pool: §97.5 billion (99.4%) are currently stored in a secure, non-circulating generator pool account. These will be exchanged for proof of generation claims of solar electricity producers submitted over the next 40 years at the rate of §1 per MWh of solar energy generated. As claims grow, these SolarCoins will be released and become part of the coins in circulation such that the growth in supply over the next 40 years should mimic the growth in solar electricity generation worldwide, assuming all generators claim their coins.
- The Genesis Pool: §500 million (0.5%) are stored in the genesis pool account for environmental charities, early volunteers, advisers, builders and maintainers of SolarCoin infrastructure. Genesis pool circulation is capped so that it will never represent more than 5% of total SolarCoin in circulation at any given time.
Did I read that right, 99.9% premine?

So you have to have trust in a centralized Generator Pool to hand out solar credits? I thought the whole point of crypto-currency was decentralization, and trust-less transactions.
