Although I won't reveal my proposed improvement in detail now, I will reveal that the solution involves objective "eventual consistency". Satoshi's design suffers from fact that blocks compete with each other instead of being complementary (additive and subtractive in the notion of sets of events). Satoshi's design is analogous to the aliasing error of point samples in a continuous space. I have a radical improvement which is going to entirely change the way everyone thinks about blockchains. This is the Bitcoin killer.
