Lightweight consensus implementation for Substrate in production?

Question

What is the most relaxed and fastest consensus implementations for Substrate? I am considering to use something much faster and lightweight for processing of social messaging on Subsocial's L2 blockchain.

Answer 1

There are trade-offs. I would recommend you start by reading:

• https://docs.substrate.io/fundamentals/consensus
• https://wiki.polkadot.network/docs/learn-consensus

Especially this post:

• What is the difference between Babe, Aura, and Grandpa?
