When staking for resources of cpu or bandwidth does it stack?

Question

When you commit your eos for staking to get cpu and net. Do these resources stack on top of another?

As in if I earned 10 cpu and 10 net one day. I get 20 cpu and 20 bandwidth the next day?

Answer 1

Yes, if you delegatebw multiple times, the values stack.

You can verify this in contracts/eosio.system/delegate_bandwidtth.cpp:

totals_tbl.modify( tot_itr, from == receiver ? from : 0, [&]( auto& tot ) {
    tot.net_weight    += stake_net_delta;
    tot.cpu_weight    += stake_cpu_delta;
});
