IF: Update fork database fork-choice rule #2273
Conversation
… instead. Move current_core to block_state.
…ate, use values for fork_database by_best_branch rule.
…Only update LIB on block qc not on votes.
Nice to see the improvements. |

Note:start |
After this PR, we no longer update LIB via votes. LIB is only updated according to qc claims in block extensions.
Update
fork_database
fork-choice rule.Computed fields for index (in order):
Potentially switches forks before starting to produce a block. Does not interrupt producing blocks once block production has started.
Includes some misc performance improvements to
fork_database
.Currently does not include voting on non-validated blocks. Would like to add the voting change in #2159 or as a separate PR.
Resolves #2125
