Yes I am doing this, but on x86.
Had to compile okcashd myself.
Works OK.

I am staking OKCash and every few days, my unspent output is split into two outputs.

Here in OKCash blockchain and I noticed something even stranger:

Just like in my case, this stake "spited" into two outputs,

While this stake "merges" together into single output,

Does OKCash stake with outputs or with total amount?

Wouldn't be more profitable if I merge the outputs into single output?
