AVAX/SOL/DOT fix ETH/BC fixing environmental concerns; that's primarily referring to PoS and different variants, right? It's worth noting that while it fixes the environmental aspect, it seems to reduce claims made regarding decentralization, wouldn't you agree? If so, one of the core tenants of crypto (arguably /the/ most significant) gets effectively traded off in favor of fixing environmental concerns. I'd imagine that would make non-BC/ETH crypto an unappealing for some as BC/ETH is currently for the environmentally concerned. I've not heard a convincing argument regarding the ability of PoS, or any of its variations, to prevent centralization in any significant way. Do you have any references you'd recommend?
