Early demand, and effect on storage costs, after launch

The sacrificial basically has farmers holding data we don’t need. The amount of this held in relation to the number of primary chunks tell us the network storage health (balance). So basically we have 50% more data copies than needed. We can lose all of that but then it’s dangerous, so the resource balance kicks in when we see this is vanishing.

50% buffer? Nice.

if sacrificial_chunks < (.5 * primary_chunks):
    increase(farmers_rewards)
else:
    decrease(farmers_rewards)

Now I begin to see how Proof-of-Resource works. There is data there, but it’s sacrificial. So the resource must always be there, otherwise the data would be gone.

EDIT: Upon further reflection, that should be 33% buffer, and the first line should be:

if sacrificial_chunks < primary_chunks
