I am u/314stache_nathy (I posted this), PoS have problems and make a hybrid sistem with PoW+PoS is bad why PoS have ‘long-range attacks’ and ‘nothing-at-stake’.
PoW is better than PoS and a hybrid sistem have other problems (in adition with PoS problems), like:
- Complexity
- The big players only be more big with time, the rich will be more rich
- The PoS turns all blockchain vulnerable to mentioned attacks (long-range attacks and nothing-at-stake).
More complexity increases the chances of a possible attack, and in PoS networks, attacks don’t need to be sustained, if PoS suffers an attack, it’s game over, in PoW an attack needs to be sustainable to work, and PoW has been much more tested and in Monero PoW is much more decentralized, the only problem is pools (PoS+PoW and PoS doesn’t solve, on the contrary, it worsens the situation, in PoW+PoS as PoW has fewer miners, and in pure PoS a government or organization can buy coins and manipulate the gain without spending large resources, and governments can just print money).
I deleted my post because I now believe that PoS won’t solve this issue, we need to further improve PoW, which is already well-tested and works well (it’s not perfect, as it still needs improvement), and PoS centralizes too much power in the hands of the richest and creates complexity in the network (which in itself increases the chances of having a vulnerability).
If you want to discuss this further, I strongly recommend joining the Matrix room of the MRL: https://matrix.to/#/#monero-research-lab:monero.social
And Monero room: https://matrix.to/#/#monero:monero.social
I’m glad that more efforts are being made to improve Monero.
