That's the end man

Check out a N95 respirator, which as Wikipedia says (if you trust this source): N95 standard of air filtration, filtering at least 95% of airborne particles that have a mass median aerodynamic diameter of 0.3 micrometers under 42 CFR 84 https://en.wikipedia.org/wiki/N95_respirator.

droplets >5µm drop within 6 ft, aerosols <5µm float for hours. cloth & surgical masks leak 40-90 % around edges, stop mostly the big drops you can see, not the tiny ones that actually carry viral load. if someone’s sick the smart move is stay home or use a fit N95, not virtue-signal with a leaky...

Would a mask filter them?

but that's not even a little funny

You can store a private key at long distances. You just can’t actively participate in the network when that far away. And you can use custodians for transactions in the meantime, like a checking account.

For on-chain transactions it is not a problem. You can still receive blocks, even if they were mined hours or days ago. So sending a transaction to the network and receiving confirmations could just take a long time. For the mining itself the consensus rules could be changed to increase the time bet...

That's such an interesting idea, I've never thought about it that way... Earth is roughly 8 light-minutes from the sun, but Mars gets a maximum distance of 20 light-minutes away from Earth... So I guess a Mars-Earth Bitcoin Blockchain is "kinda" feasible, but once you get out to the Belt, other sys...

Just US

I remember seeing a collection of data on why Len sassaman was probably Satoshi and it was the most convincing among possibilities. But I don't remember any of that data because I really couldn't care less who satoshi is.
