If I understand correctly RSK allocates a certain percentage of mining back to dev funding.
As I was not aware of this, could you please add a source?
If RSK is open source wouldn't it be possible to fork the code and remove this "tax" on mining? The same thing happened with ZCash and there is a fork of ZCash called ZClassic without the tax.
Without looking into RSK, it should be very well possible to create a fork without the tax. The tax concept on mining is ludicrous anyways.
It seems like bitcoin sidechains that are open sourced will always be forked from one "inefficient" form of money to another. So to create the best coin you have to make it appealing for all users.
Correct, that's a benefit of a free market.
