It seems Tezos is moving towards the Tendermint consensus, used by Cosmos. However, wouldn't a Grandpa & Babe consensus mechanism, as used in Polkadot, allow for better block scaling?
EDIT: I am posting a paragraph by Kerman Kohli's article here, which explains the above:
"Polkadot’s consensus mechanism consists of two components: GRANDPA and BABE. GRANDPA is a finality gadget which draws on some ideas behind the GHOST fork choice rule (like Ethereum’s Casper) and BABE is a block production mechanism similar to Cardano’s Ouroboros. The introduction of a finality gadget allows for portions of the chain to be “finalized” and provably never be reverted. Separating the finality gadget from the block production allows for the slower finality gadget to work in a different process from the generation of new blocks in the chain. This means that the actual production of blocks can scale unlike in the PBFT-bound Cosmos Tendermint algorithm."
