I've been trying to figure the essential _features_ of the The Ethereum (computer) vs. mere _implementation_ "details"; so far have come up with: 1. strong integrity protection for your code (customarily called "smart contract"), 2. strong availability for your code. (1/)

If you’re thinking of playing with smart contracts, you might want to look at Michelson on Tezos rather than Solidity on Ethereum

Or iele which will have formal verification https://iohk.io/blog/iele-a-new-virtual-machine-for-the-blockchain …

Damn, very nice!!

It will be out pretty soon

Satellites are vulnerable to ASAT missiles, unless in higher orbits, the latter making connectivity more problematic. Connectivity already is a weak spot of this idea.
-
Launching missiles is typically costly (not speaking of the cost of the actually missile launch).
-
For ASAT purposes, suborbital launches are sufficient. Precision is key, but these systems are much cheaper than satellite launchers https://en.wikipedia.org/wiki/ASM-135_ASAT …
-
Yes, but the political implications would be huge. That’s why I already replied in my previous tweet ;-)

Any part of a server could fail. Even with redundancy, bizantine faults happens. In orbit, the server would be more exposed to cosmic rays (https://m.slashdot.org/story/322717 ). Software bugs could not be fixed, nor software forked. Security of the launching process could be compromised.

@ElonMusk could make space for open source hardware of this type in Starlink satellites.Thanks. Twitter will use this to make your timeline better. UndoUndo

At least that wastes no more energy than blockchain

Chief complaint is things must evolve, and that's somewhat impossible with unreachability-based trust. And with stealth hardware implants out in the wild, guarantees of this kind of isolation are too weak anyway. But I like the consideration of price we have to pay for trust..

Then we'd all be trusting you for the integrity of the computations since you assembled the hardware, you could backdoor things. The point of Eth is that everyone's checking your work, so theoretically nobody can alter it.

Multiple satellites is probably the cheapest way to make shooting it down expensive (and protects against the very real problem of the junk floating around up there).

Resilience is another essential. Real environments are not free motion in vacuum. You need a system that can absorb hits.
