    But it's pretty easy to address this. The CoinsViewCache's underlying storage is just a std::map. A while ago, I replaced that with a sparsepp hashtable to improve the memory efficiency. It wasn't hard to do; took a couple of hours. We could do the same thing with a concurrent hashtable implementation. The hardest part of doing this would be picking an implementation and validating that it's mature and stable enough to be used in BCHN. Intel's Threading Building Blocks has some good candidates, but it's also possible that another implementation might be more suitable.

    Hey thanks for the mention /u/jtoomim. I see that you used sparsepp in CoinsViewCache. A phmap::flat_hash_map would probably be similar for memory usage, but likely faster (because of parallel lookup with SSE instructions and contiguous memory storage in one array).
