Abstract

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.

Motivation

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.

Specification

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.

  • The time between blocks MUST be changed from 12 seconds to 600 seconds (10 minutes).
  • The per-block validator reward MUST be multiplied by 50
  • The number of blocks per epoch MUST be reduced from 4 to 2

Rationale

  • The block gas limit is multiplied by fifty to compensate for the time between blocks being multiplied by fifty.
  • The per-block validator reward is also multiplied by fifty to compensate for the time between blocks being multiplied by fifty.
  • Epochs are changed to be 2 blocks long so that finality can be reached in a reasonable amount of time.

Backwards Compatibility

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.

Test Cases

TODO.

Security Considerations

Definitely needs discussion.
