  • According to the official GitHub repo update, this is what the upgrades will deliver.
  • BEP-126 (in its 1st part) is aimed at introducing a “fast finality mechanism.” In essence, this is a step that intends to finalize a block and once the block has been finalized, it won’t be be reverted forever. The 7-step process is thoroughly stated here.
  • BEP-174 is titled Cross Chain Relayer Management. The proposition introduces a brand new governance proposition type that’s designed to manage the set of whitelisted relayers. In more non-technical language, it’s aimed at introducing a new way to manage Relayer Manager public keys that will be stored in the genesis contract on the BSC. Relayer Managers will be able to manage their individual relayer public keys.
  • The last one is the CometBFT Light Block Validation proposition (BEP-221) and it proposes a system that would add a new contract to the networks that make use of the technology.
