BABE Consensus Mechanism

Blind Assignment for Blockchain Extension (BABE) is the consensus protocol used by Hippius to determine block production rights.

How BABE works:

1. Epoch-based timing: The chain is divided into epochs (time periods)
2. VRF-based slot assignment: Validators use Verifiable Random Functions to determine if they have the right to produce a block in a given slot
3. Probabilistic finality: Initially provides probabilistic finality
4. GRANDPA finality: Works alongside GRANDPA for deterministic finality

This hybrid approach ensures both consistent block production and fast finality, making the network responsive while maintaining security.
