Current Consensus Fees

No fee if

  • tx less than 1000 bytes in size

  • all outputs are 0.01 BTC or larger, and

  • priority is large enough

  • ==Priority = (sum of inputAge*inputValue) / (trans size)==

Otherwise fee is 0.0001 BTC per 1000 bytes

Transaction-Demand Model

T = total transaction value mediated via BTC ($/sec)

D = duration that BTC is needed by a transaction (sec)

S = supply of BTC (not including BTC as long-term investments)

  • ==S/D = BTC become available/second==
  • ==T/P = BTC needed/second==
