    """
    From the user's perspective, this is not a wallet at all, but a way to control
    whether their pooling-enabled plots are being self-farmed, or farmed by a pool,
    and by which pool. Self-pooling and joint pooling rewards are swept into the
    users' regular wallet.

    If this wallet is in SELF_POOLING state, the coin ID associated with the current
    pool wallet contains the rewards gained while self-farming, so care must be taken
    to disallow joining a new pool while we still have money on the pooling singleton UTXO.

    Pools can be joined anonymously, without an account or prior signup.

    The ability to change the farm-to target prevents abuse from pools
    by giving the user the ability to quickly change pools, or self-farm.

    The pool is also protected, by not allowing members to cheat by quickly leaving a pool,
    and claiming a block that was pledged to the pool.

    The pooling protocol and smart coin prevents a user from quickly leaving a pool
    by enforcing a wait time when leaving the pool. A minimum number of blocks must pass
    after the user declares that they are leaving the pool, and before they can start to
    self-claim rewards again.

    Control of switching states is granted to the owner public key.

    We reveal the inner_puzzle to the pool during setup of the pooling protocol.
    The pool can prove to itself that the inner puzzle pays to the pooling address,
    and it can follow state changes in the pooling puzzle by tracing destruction and
    creation of coins associate with this pooling singleton (the singleton controlling
    this pool group).

    The user trusts the pool to send mining rewards to the <XXX address XXX>
    TODO: We should mark which address is receiving funds for our current state.

    If the pool misbehaves, it is the user's responsibility to leave the pool

    It is the Pool's responsibility to claim the rewards sent to the pool_puzzlehash.

    The timeout for leaving the pool is expressed in number of blocks from the time
    the user expresses their intent to leave.
