This is something that& #39;s been on my "super very nice to have" list for quite some time & as I& #39;ve been meeting heavy for the past few days I thought I& #39;d throw the problem at the #flexathon code base ...

@elonmusk this is for you buddy!
#blockchain #crypto #defi #dlt

I set up 2 disjoint networks that are independent yet know about each other. Same genesis on each network, but with a different "magic" that acts as it& #39;s ID

State hashes are prefixed with the network ID for routing.

Most of the #cerberus code stays the same ...

The principles are the same as a regular non-interplanetary network. I& #39;m looking for a 2/3rds vote majority in all shards before committing.

I also built in a bunch of latency on messages that pass between the two networks to simulate Earth <> Mars comms (~14 mins).

Aside from the latency & the routing, the network acts in the same way.

Assume that I& #39;m on Earth & I wanna send some funds to Mars.

My funds live in shard E10 & I& #39;m sending them to shard M20. (E = Earth, M = Mars)

The Earth nodes know that the Mars network exists & that my funds are being sent there. So they send the transaction to Mars, where nodes pick it up.

Both E & M nodes then do the usual #cerberus voting to produce a certificate with a yes/no decision.

The E nodes communicate those certificates to the M nodes and vice versa.

If both certificates are of a 2/3rds yes decision, both sides commit. If not, both sides fail.

"Local" transactions that don& #39;t leave the planet (lol that sounds so absurd) work in the same way, except of course there is a LOT less latency.

This was a super crude & quick test so I& #39;m probably missing a bunch of edge cases, but I wanted to test #cerberus principles in a very high latency environment. Mimicking an Earth->Mars transaction seemed a fun way to do it :-)

I& #39;ll certainly be looking more at this though!
