would it make sense for this to return a span<const uint8_t> or a const std::vector<uint8_t>&? (as well as GetId() below)

I agree span would be nice in many places but we have C++17 set here still so this feels out of scope. I changed the return to const reference though 👍 (https://github.com/Chia-Network/chiapos/compare/fb796346df762224973f92d4628b6e994b49ba00..b06302c6fc9f9c914110002698d91f3741cea6c6)

This is a clear improvement

delete[] memo;
return ret;
std::vector<uint8_t> memo = dp.GetMemo();
return py::bytes(reinterpret_cast<char*>(memo.data()), memo.size());

Its probably not a big deal, but this will copy the buffer twice, where i would think once is enough

Changed!

py::bytes ret = py::bytes(reinterpret_cast<char *>(id), kIdLen);
delete[] id;
return ret;
std::vector<uint8_t> id = dp.GetId();
