Summary

Below is a order of operations to produce the mvp light client and evidence module needed for the 0.34 release

  • 1 : Remove ConflictingHeadersEvidence
  • 2 : Remove LunaticEvidence
  • 3 : Remove PotentialAmnesiaEvidence (remove polc and amnesia evidence)
  • 4 : Move provider handling code out of light client and into provider (e.g. exponential backoff, validate basic)
  • 5 : Create light client attack data structure
  • 6 : Add full node verification, gossiping and committing
  • 7 : Create light client detector for processing conflicting headers
  • 8 : Store relevant vote information in evidence db
  • 9 : Write byzantine integration tests

Post 0.34 possible LCEH follow up work

  • Create a handler to manage providers for the light client
  • Set up p2p providers
  • Use light blocks internally instead of validator set + signed header combo
  • Migrate maverick light client integration tests and tests for rpc endpoints
  • Startup from genesis
  • Full amnesia evidence protocol

Closing this as (hopefully) all relevant 0.34 evidence work has been done and all remaining post 0.34 work already has a respective issue for it
