Interesting! A block lattice seems like a nice thing. It would be problematic with regards to money creation though. As we get more blocks per 10 minutes, we get more block-rewards (new bitcoin) per minute. It also seems weird to 'amend' history by saying some other stuff also happened. Thinking of this, could you maybe use this to somehow block a payment by adding a 'past block' that already spends the bitcoins in your payment?
