Creating an Ergo mining pool

So, in summary, the following approach for a mining pool would work:

  1. Every share of Alice should correspond to a block that includes a pool transaction that pays some fixed amount (67.5 or some slightly lower) to the pool address.
  2. The reward will be paid to some public key chosen by Alice. say, alice.
  3. The pool transaction must be funded from a box (i.e., UTXO) protected by the script
    minerPubKey == alice|proveDLog(alice).
