But the beauty of Decred is the hybrid block validation where stakers have the final say in validating mined blocks. This maintains decentralization while keeping the security of a network with more hash power. I can only see Asics as a good thing for the future of Decred.
How exactly do I decide what blocks are valid when voting? Why would I want to vote any block as being not valid? Not to mention that putting a "no" vote in a block I am called to vote would result (if the no prevails) in the block becoming orphan and therefore no stake reward for the ticket.
Also the whole voting/staking system is automatic. My tickets are called to vote and they do. I never choose any yes or no for the blocks, I don't even know how. I only know how to vote for other stuff when available, like the lightning network or ticket price algorithm change.
Finally, with staking pools active and used by most, you could argue that staking is also quite centralized.
