I am also an advocate for split-PoW mining, like Tari has (they have three mining algorithms that rewards are split between — one is merge mined with the main Monero chain, the second is ASIC friendly, and the third is optimized for GPUs). Each gets a segment of block space and rewards, to make reorgs harder and discourage extortion via selfish mining.
I don’t like proof of stake as the primary consensus mechanism, but I also think intermittent proof of stake every n blocks with a diminished mining reward is also a nice potential validation mechanism to make reorgs harder.
Monero endured a sustained 51% attack pretty recently with no double spends. People came out of the woodwork to provide hash power from various sources, myself included. This is our future. This is our children’s future. We’re not going to sit around jerking off when our chain is under attack. We will hold the line. States might be able to come up with a lot of hash power but I can too.
