    Why doesn't that mean that coins can only be transferred through the sneakernet? If you get coins from someone else do you have to trust them to have the plot still around?

      That wouldn't make for a very useful global ledger :) Once a farmer wins a block it's theirs, the same way it works with bitcoin. The reward is tied to a public key, not the original storage. Just like in bitcoin once a miner wins a block they don't need to continuously prove that they have x amount of hashing power in the future.

  There's two parts to Chia: plotting and farming. Plotting is a one-time cost of ~5-10 hours for a SSD, and after that you can start farming and you continuously earn Chia by proving your drive still contains the random data that got initialised during plotting. Erasing the drive would mean you have to start over and you lose ~10hrs of income.
