I was reading this blog post From Classic to Hydra and I was wondering which version of Ouroboros is currently implemented in Cardano: Classic, BFT or Praos?
1 Answer
Ouroboros family implementations
- Classic implemented in 2017
- BFT implemented
- Praos is currently running
- Genesis (development's in progress...)
- Hydra (development's in progress...)
- Crypsinous (development’s in progress...)
- Chronos (development’s in progress...)
- Leios (development’s in progress...)
- Omega (brings together Classic, Praos, Genesis, Redux, Chronos, etc...)
Eras
Some of the above algorithms have mutually dependent ingredients for launching a certain era:
- Byron Era (Foundation) – reached in 2017
- Shelley Era (Decentralization and delegation) – reached in 2020
- Allegra Sub-Era (Token locking mechanism)
- Mary Sub-Era (Multi-asset implementation)
- Goguen Era (Smart Contracts, DeFi, Dapps) – hit Testnet in September 2021
- Alonzo Sub-Era (Smart Contracts implementation)
- Babbage Sub-Era (Eliminates flaws of Alonzo)
- Vasil Sub-Era (Increases network's scaling capabilities) – reached in July 2022
- Basho Era (Scalability and Interoperability) – be ready for it in 2023
- Voltaire Era (Governance) – development's in progress...

3And Omega is in planned state as far as I know. If everything is OK next year should be implemented. Commented Sep 10, 2021 at 8:11

1According to this tweet Ouroboros Chronos should be part of Omega.– user142Commented Oct 2, 2021 at 10:03
