Turing Award winner's blockchain project [audio]

I really like the way Conflux combines POW and a DAG. With that said, I still do wonder how the economics are supposed to work out.

Once multiple blocks are produced at the same time, what is stopping the miner with the greater hash power from just stealing the transactions (and their associated fees) from the side-blocks and moving them onto the larger chain. This sort of economic substructure feels like a leap of faith. Maybe it will work, but Bitcoin does have a single thread of miners and blocks for a reason.

Andrew Yao is the only Chinese recipient of the Turing Award. Interesting show on his blockchain project for those who follow these things.
