    Really like this way. For consistency reason, I don’t like capital letters, though I use camel case mostly

    The selfish-mine paper has the same issue. It assumes that miners follow the first block heard when two blocks of the same height generated, but actually miners should follow the block of greater weight. This will affect greatly the probability analysis of the paper

    If the honest miners follow option 1, with some probability (> 0.5), block BA will not be included in the chain. The expected reward of attacker reduced too. The probability is > 0.5 because the hash weight of Bi will be greater with probability 0.5. Would this make sense?

    I propose a new work called PoLW to reduce the energy consumption of PoW without sacrificing security. For a practical system where mining is profitable, PoLW could improve network security by converging earlier to equilibrium state. Check it out here:

    Why does ethereum support regular rpc calls in it’s websocket apis? My understanding is that ws should focus on real-time data

    I tried once to add types to some python code. That piece of code became pretty ugly in the end, as the code itself involves nontrivial types

    The main change is to add data dependencies into state Merkle tree. The trade-off is a bit storage and computation overhead. I don’t think this should be enabled by default, the overhead is useless for many nodes. The contract needs such kind of dependencies can implement it.
