Finality of Cardano transactions

The team designing the network consensus must carefully balance each feature. What is advantageous from one perspective may be disadvantageous from another. It is impossible to design a single best solution that has no drawbacks. Only diligent research and technological progress allow us to move closer to the ideal solution. Cardano uses Nakamoto-style Proof-of-Stake, which means, among other things, that it has probabilistic transaction finality. Come and read what this means and what are the advantages and disadvantages.


The IOG team preferred liveness and security over transaction speed for the current version of PoS. Modern PoS networks combine the benefits of probabilistic and provable finality. Ouroboros Leios can change that.
