BIP 119 is not new, but since talk of activation ramped up a lot this month we are going to take the opportunity to go over it. The main goals for the discussion are:

  • understand use cases,
  • estimate implementation and maintenance complexity,
  • situate the proposal among alternatives, and
  • go over considerations for activation and activation methods.

Binance dropped 200mb+ worth of bitcoin transactions into the mempool consolidating their utxos. The transactions all have a fee of 14sats/vbyte. This fee is too high, why not drop them with 1sat/vbyte?
