• split into base fee and prioritization fees
  • base fees is a fixed 5000 lamports per signature
  • prio fees are priced in micro-lamports per compute unit
  • acts as a price signal, making transactions more economically compelling for validator nodes to include it

total fee = prio fee + base fee

prio fee = CU price ( in micro lamports ) x CU unit limit


currently:

50% of all txn related fees are burn 50% are going to the block producer

a new change ( SIMD 96 ) is going to make 100% of the prio fees to go to block producer

base fees will still be burnt
