This EIP makes a minimal number of changes to allow Ethereum to be used on the moon and other potentially habitable bodies in Earth's solar system. It changes the time between blocks, the per-block validator reward, and the number of blocks per epoch.
It is impossible for today's Ethereum to literally "go to the moon" due to a limitation in the protocol: the block length. Should validators attempt to validate on the surface of the moon, they would find that the ~1.25 second communication delay (caused by the speed of light) might cause issues with synchronization, considering the 12-second timer between blocks. The validators would eventually be ejected on the terrestrial chain after leaking. If however a substantial number of validators are displaced (think 1/3), they might follow their own fork and would eventually eject the terrestrial to finalize their own chain.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 and RFC 8174.
Many applications expect mainnet transactions to be included in a short amount of time. This would clearly no longer be the case. Such applications should switch to planetary rollups. Syncing rollups across heavenly bodies is outside the scope of this proposal.
TODO.
Definitely needs discussion.
