@danrobinson They want PoW to be the ultimate top dog, the casper FFG style of hybrid makes PoS the ultimate top dog and PoW a mere helper, whereas the older hybrid PoS ideas make PoW and PoS equal co top dog, so it's less risky politically.
@danrobinson他们希望PoW成为最终的顶级犬，casper FFG风格的杂交犬使PoS成为最终的顶级犬，而PoW只是一个帮手，而较旧的杂交PoS理念使PoW和PoS成为共同的顶级犬，因此政治风险较小。
