> You are creating a false dichotomy: security is an integral component of bitcoin transactions, and if security costs, transactions cost as well that would be true if only on-chain settlements would count as transactions in BTC ecosystem. there are more ways to exchange BTC with security landing anywhere between very low and on-chain settlement. thing is, that it's not even transactions that have security, it's blocks. energy is spent to make sure that it's expensive to override/rollback blocks. and it's true that blocks exist to assert ordering of on-chain settlements, but it's not true to claim that there is 1-1 correspondence between on-chain settlements and transactions. each on-chain settlement can embed trillions of bitcoin transactions (in colloquial sense, exchanges of an asset). what does that do to your "energy per tx" metric?
