MWC

MWC is an in-progress implementation of the MimbleWimble protocol. Many characteristics are still undefined but the following constitutes a first set of choices:

  • Clean and minimal implementation, and aiming to stay as such.
  • Follows the Mimblewimble protocol, which provides hidden amounts and scaling advantages.
  • Cuckoo Cycle proof of work in two variants named Cuckaroo (ASIC-resistant) and Cuckatoo (ASIC-targeted).
  • Relatively fast block time: one minute.
  • Block rewards decrease at regular intervals, until the total supply of coins reaches the fixed limit of 20 000 000 MWC.
  • Transaction fees are based on the number of Outputs created/destroyed and total transaction size.
  • Smooth curve for difficulty adjustments.
