something consistently in the back of my mind whenever i’m working on cross-chain swaps / chain abstraction:

does this thing still get the job done once we’re multiplanetary?

blockchains in space are absolutely inevitable, and if what we’re building doesn’t work on mars then GTFO

I've thought about this a lot too. the time delay is an issue, but since we already have networks that don't immediately batch transactions it's not an impossible hurdle.

~13m for data to travel from Earth <> Mars, so you could certainly have attestations that take that into account, or perhaps even a set of validators that are specifically for obtaining txs from other planets and then batching them in a way that preserves the most value

arbitrage opportunities could get wild though, if say on Earth ETH is going up, but on Mars some event occurs that tanks the local price. would be interesting. I'd imagine by the time we're multi-planetary we'll have stations between planets, which could help pad the total time delay a little bit

it's going to be interesting for sure!
