Mina uses a Nakamoto-style, “longest fork” consensus which is great since this approach to consensus allows for maximum decentralization. At a high level, the tradeoff compared to alternative BFT consensus protocols is slower time to finality. I came across this paper which claims to realize the best of both worlds and thought it was worth starting a topic here for discussion: [TaiJi: Longest Chain Availability with BFT Fast Confirmation](https://eprint.iacr.org/2020/1470) The abstract claims: > We present a new construction which combines a longest chain protocol and a BFT protocol to get the best of both worlds. While the paper is focused on PoW chains, a substrate project (Polkadot’s ecosystem) called [Subspace](https://subspace.network/) is using a variation of TaiJi for their “Proof of (Storage) Capacity” consensus (their consensus whitepaper is [here](https://assets.website-files.com/61526a2af87a54e565b0ae92/617759c00edd0e3bd279aa29_Subspace_%20A%20solution%20to%20the%20farmer%27s%20dilemma.pdf)). I would assume TaiJi could theoretically be applied to PoS as a result. Curious to hear what others think of this possibility and whether TaiJi is a legitimate innovation? At a minimum, this topic may be useful for future reference as consensus becomes a higher-priority aspect of the protocol. Cheers 🍻 , Brett
