A bit more insight into why the faucet now works this way:
You can get a one-time allocation of a small amount of FIL to any address, to initialize your miner and pledge some sectors.
Once you have a miner with at least one sector, you can use the faucet to send FIL to that miner. The amount of FIL is proportional to the rate of storage growth for the miner over the last 24h.
The goal is to create a minimal “proof of work” for the faucet. Previous faucet designs let a few bad actors spam and abuse the network, or pay massive, unrealistic transaction and gas fees instead of learning to set fees properly.
We’re hoping this faucet design will create more realistic conditions compared to how Filecoin will work at mainnet.
