With POW, the miners who finds the block chooses the order of transactions in that block. How will this work with POS?


POW and POS are both methods of choosing the miner who will have the privilege of appending a block to the canonical chain.

POS doesn't change the idea of ordering transactions in ordered blocks. It changes the method of selecting a miner.

Hope it helps.

  • From my understanding, to be a "miner", you stake your x ETH. Do each of these "miners" now have the opportunity to choose the tx order? Feb 8 '19 at 19:08
  • Any if all "miners" are equal, how does the software choose the miner? Feb 8 '19 at 19:10

    In both cases, the miner has that privilege over one block at a time. In POW, it has to solve a puzzle to win the privilege. In POS they acquire that privilege in proportion to their stake. Implementation details may vary. As a general model, think of a "miner" who has staked 5% of all funds staked by all miners. They might get the privilege every 20 blocks - 5% of the time.
