This update brings new consensus protocol, Ouroboros BFT which is required to move from Ouroboros Classic which is the current consensus protocol on the Cardano network. The network will be moving to Ouroboros Genesis, which is a Shelley based protocol.

This will make Cardano first Proof of Stake protocol that matches security guarantee of a proof of work protocol like Bitcoin.

The Ouroboros BFT will not be activated after v1.5 release though, but it will be activated via a protocol update later that will be announced separately.

As mentioned earlier, the Classic protocol will be deactivated and BFT consensus protocol will be activated via protocol update. One can say that it is a hard fork but something that takes place in a very smooth and automatic way.
