Polkascan Development Update #5
This development update is part of our work that provides the Polkadot-ecosystem with an enriched Substrate Interface (API) for any Substrate-based blockchain with full decoding context of the chain’s respective runtime.
Polkadot Consensus Part 3: BABE
Blind Assignment for Blockchain Extension (BABE) is a block production engine that was inspired by Ouroboros Praos, another proof-of-stake protocol. It can be used on its own because it provides probabilistic finality, or it can be coupled with a finality gadget like GRANDPA.
Polkadot Consensus Part 2: GRANDPA
In the introduction to this series, I outlined that a consensus algorithm helps a network of computers answer three questions. GRANDPA addresses the second.
