Yep, here are some comparative carbon costs:
US Military:
59 M Tons 2017.
BTC:
22 M tons 2018,
37 M tons 2021,
130 M tons by 2024 predicted in China before shutdown,
Banks:
1040 M tons
IMO, the idea of a $1,000,000 BTC would be a huge hit on reducing CO2, as cost of mining approaches BTC price.
> Hork up a bunch of space probes
Here is a variation on that idea: One of the claimed advantages to satellite is lower latency (see https://www.groundcontrol.com/Satellite_Low_Latency.htm https://www.groundcontrol.com/Satellite_Low_Latency.htm) Solana is claiming layer 1 blocktime of 400ms by synchronizing clocks. For Global coverage, I think satellite is a requirement to achieve that throughput as consumer latency is at least double that. This isn't proof of work; Solana calls its method proof of history.
IMO, PoW is the like the Cray Supercomputer of the 80's. My Apple Watch is lot more powerful at -let's see- 1/64,000,000th the cost.
- spiralx 5y ago> US Military: 59 M ... Banks: 1040 M tons I have no idea where you got these numbers from, but the idea that banks produce 17 times as much CO2 as the entire US military - with all of its fossil fuel-burning vehicles - is obviously ridiculous.

- wiml 5y agoIt sounds like banks are being credited with the carbon emissions of everything they loan money to? Should the US military be credited with the carbon emissions of everything they either defend or attack?
- musesum 5y agoThe article wasn't very clear; I think it means the related footprint of internal operations, such as real estate, employee travel, and the like. At least, if you go by https://www.epa.gov/climateleadership/scope-3-inventory-guidance https://www.epa.gov/climateleadership/scope-3-inventory-guid... The military is a separate article. A sankey diagram would be less ambiguous: https://flowcharts.llnl.gov/ https://flowcharts.llnl.gov/
- spiralx 5y agoSo banks actually produce about 1.5M tons of emissions then according to your link.
- musesum 5y ago> So banks actually produce about 1.5M tons of emissions then according to your link. Wrong; Gigatons.
- spiralx 5y agoIt said emissions from activities relating to loans are 700x direct emissions, 1.04 Gt / 700 is 1.5 Mt.
- musesum 5y agoWhat's the total addressable market for disrupting carbon footprint of banks? When every person is their own bank, there is less need for brick-and-mortar real estate, the employees commuting, and the like -- what the EPA calls "Scope 3" effects, as per: https://www.epa.gov/climateleadership/scope-3-inventory-guidance https://www.epa.gov/climateleadership/scope-3-inventory-guid.... The above carbon TAM is why I'm pro-crypto, as soon as we move past PoW.
