Side Effects

The firewall should be able to trigger external sync/async events in response to specific requests.

Example: Users could deposit some "Gas Fees" into an account controlled by the node operator, when a transaction is pushed to the node operator node by an account with a balance, if needed, funds are pulled from their deposit to trigger a PowerUp for their account. This would simplify the user experience and remove the need for end users to worry about resource management on a per transaction basis. Just deposit some gas fees occasionally. There is some trust required on behalf of the node operator to only trigger PowerUps when necessary and also to use the funds to PowerUp the target account.

In the above example, The node operator needs to trigger a PowerUp and ensure the transaction is on-chain before triggering the action signed by the requestor, so it should be synchronous.

The logic to trigger the PowerUp does not need to be built into the firewall but some hook for an external script. In this way additional logic and plugins could be easily adapted using Go and Nodejs.
