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

Go all the way. How would consensus algorithms account for the different relative rates of time passing between planetary systems, or even galaxies?

different planetary systems and you’re basically just receiving a stream of checkpointed commitments that take years or decades to arrive

different galaxies and you’re well and truly not able to achieve any kind of communication without some FTL hack or quantum entanglement or something

Multi-generational interplanetary wars will be fought over L2 hard forks. 🙏
