fixed fee on H burn

• $H staking loan proved its utility and reliability during last several years
• simplicity of initial implementation did not include any value extraction from discussed mechanism
• lets add simple and effecient value extraction
• on each operation of $H burn collect and burn fixed fee defined by consensus param
• proposal of fee value: 2%
• example
  • i want to burn 400 $H

  • my fee is 4 $H

state	frozen $BOOT of neuron	$H of neuron	$H supply
starting	1000	1000	10000
ending	604	600	9996

• you see that in proposed scenario neuron must supply a bit more $H in order to unstake all $BOOT
• that could be a problem in case of automatic fuel
  • but in explicit mint and burn of H
  • neuron make conscious decision to
  • pay for using staking loan
• this simple model is sustainable source of value for superintelligence
