* Achieving this property requires sacrificing some nice-to-have features of other

|

*
|

* The two main design features are:
|
||||
* 1. This implementation does not use `update_price_feeds_if_necssary` and simulate the transaction
|
||||
* before submission. If multiple instances of this pusher are running in parallel, all of them will
|
||||
* land all of their pushed updates on-chain.
|
||||
* 2. The pusher will split the Coin balance in the provided account into a pool of different Coin objects.
|
||||
* Each transaction will be allocated a Coin object from this pool as needed. This process enables the
|
||||
* transactions to avoid referencing the same owned objects, which allows them to be processed in parallel.
