Tezos (XTZ) have allegedly achieved what Ethereum (ETH) is attempting to do. That said, ETH has a considerable lead over Tezos in terms of network effect but ETH is struggling with its scalability issues. In the second half of 2019, ETH was working at 94% of its capacity which underscored the need for a more scalable solution, hence why its transformation from proof-of-work (PoW) into proof-of-stake (PoS) is critical. Overcoming this issue is not expected until the second half of 2020 at the earliest. Meanwhile, XTZ is a multi-purpose platform that supports dApps and smart contracts that uses delegated proof-of-stake (DPoS) and supports Turing complete smart contracts.

XTZ, on the other hand, is potentially already there. Keep in mind that some reported achievements by the press can be overzealous thus price/volume action, as always, remains key. So far, XTZ has been well outperforming ETH since Jun-2019 which is a solid clue.
