Scalability and the amount of transactions per minute (tps) is something that is often used to validate projects. Even though a high tps count is ideal, it should never be at the expense of decentralization. Decentralization is always key for the success of cryptocurrencies. It is what makes a cryptocurrency trust-less, secure and immutable. A high tps count isn't crucial for a project to have huge success either. If we take a look at Ethereum, we see that just 10 transactions per second (tps) can go a long way. Tezos can already outperform Ethereum transactionwise: Tezos' tps recorded so far is about 13 tps. Carthage006 increased the gas limit though, so now tps should be closer to 18 tps. Low tps values can cause issues at rush hours though. We have seen that in Ethereum quite a few times. So everyone is always looking for a way to improve tps values without hurting the level of decentralization. And there is a huge improvement that is being worked on for Tezos: Tenderbake.
Tenderbake is a Classical BFT Style Consensus for Public Blockchains that will bring deterministic finality to Tezos. Adding to that, the combination of Nakamoto-style consensus algorithm with a classical BFT style algorithm should also provide up to 50% attack resistance.
Tenderbake is being developed by Nomadic Labs in collaboration with CEA-LIST. You can read theTenderbake paper here. They have been researching this since 2018, and CEA-LIST is an impressive partner. CEA-LIST is one of three specialized technological research institutes of CEA. CEA is a French Government funded research organisation with an annual budget of 4.7 billion Euros. (Source)
So far no info has been released about the tps that this improvement will provide. But Tendermint has a blocktime of 1 second and if Tenderbake will lower Tezos' blocktime to that same level without decreasing the amount of transactions per block, it would bring Tezos' tps to 1,000+. That is a pure guess though, Tendermint can handle 10,000 tps, so who knows what's in store for Tezos.
Lately Nomadic Labs revealed they would probably launch Tendebake testnet this year:
After a successful testnet, implementation in the Tezos main chain is a smooth process. Tezos is build for swift evolution and seems to deliver on its promised potential. The next upgrade, which will be implemented somewhere in the next 4 months, includes privacy features. One of the next ones is quite likely to include a huge improvement in scalability.
