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

1 Answer 1


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, 2019 at 19:08
  • Any if all "miners" are equal, how does the software choose the miner? Feb 8, 2019 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.
