      - Threshold security = some given amount of USD expenditure is sufficient to secure the chain, no matter how valuable it is - Flow security = security spend should be a function of economic throughput - Stock security = security spend should be a function of network value

      Bitcoin's primary security model should be thought of as:

      In other words: - Threshold: at some $x security spend, we are safe no matter what - Stock: BTC is like a bank, wall thickness shd be proportional to $ value of gold inside - Flow: we need to spend on security relative to payoff from 51% attack which is relative to throughput

      I like the definitions, although IMO "primary" security is a combination of stock & flow 🤔 The reason I think it's not exclusively one or the other is because stock shows up as the much larger cost, but it wouldn't exist without flows. After all, stock is the integral of flows.

      That means that if the flows are too small, stock wouldn't amount to much either.

      Agreed, they are related. Flows creates stock, and perhaps vice versa? As per @saifedean: more miners - > more hash rate -> more security -> more attractive -> more price -> more miners

      Yes, I think stock & flows are inextricably linked & essentially 2 sides of the same coin. E.g.: Plants turn CO2 from the atmosphere (stock) into O2 via photosynthesis (flow). Animals then consume O2 (flow) & spit out CO2 back into the atmosphere (stock).

          The distinction is mostly a time horizon one and the attack you are designing against

          Replying to @nic__carter @hugohanoi and

          If it's profitable to attack stock, then flow is also insecure, so stock is what should be secured. In reality, next block's flow is what pays for its own security. The model hopes this will be enough to cover stock as well.
