Task summary

  • gossamer and polkadot currently are implementing different selection algos for the best chain. gossamer uses the older algo which is just longest chain + earlier block to tiebreak. however polkadot is weighting blocks built w primary slots higher than those built by secondary slots.
  • see here https://wiki.polkadot.network/docs/learn-consensus#fork-choice
