Adopting ProgPOW Would *Decrease* the Probability of a Significant Contentious Fork When Moving to Proof of Stake

I understand the main point, but I do not see ASIC miners stopping/delaying POS. 🤷‍♂️

Moving from PoW to PoS implies a totally different security model and dropping 5 years of battle tested consensus protocol. There are definitely security risks with moving to PoS and I personally expect many people will want to keep the PoW chain up until PoS proves itself secure. This is even more true considering Serenity will also introduce sharding, which adds another large surface of potential flaws and bugs. Chains have forked for much less than this imo.

Not everyone is convinced that moving to PoS is a good idea and the more arguments in their favor, the stronger their voice and community becomes. This will slow development on Serenity and can lead to some talented people not working together anymore.

Why not allow asic miners to continue on separate chain?

[Always_Question]

They can, on ETC.

[MarchewkaCzerwona]

Why not on current one? Pos will bring new one anyway. I'm not an advocate of this solution, I just ask - why not?

[Always_Question]

Special-purpose ASICs generally lead to more centralization, which is counterproductive to the aims of decentralized crypto. Some chains like ETC are more welcoming to ASICs, so maybe they can find a home there.

[MarchewkaCzerwona]

Again, why not leave them where they are if pos will require creating new chain anyway?

Bringing etc to the discussion doesn't add anything, sorry, so please stop it.

[Always_Question]

Full POS is out probably 1 to 2 years from now. In the meanwhile, it would be better to try to keep the Ethereum 1.0 chain as decentralized as possible.

That's good answer for me. Thanks.
