(reward + avg fee) * 144 * 365 (one year) == approximate investment needed
to reorg the chain for a double-spend attack
in 30 years, assuming fees are still negligible (why wouldn't they be?
layer 2 works and layer 3 is coming), that's only 1200 bitcoin. not really
a lot.
there's only few things that allow that security budget to be ok
- we assume the price goes up a lot
- we assume transactions get a lot more expensive
- we don't care about double-spend attacks for very large transactions
i'd rather engineer block demand than ignore it
