Optimize speed of reward distribution about jungletv HOT 5 CLOSED

Some optimization was already made in my gonano fork to speed up publishing of many consecutive send blocks.

@Airtune gave me the idea of using the visitors' browsers to help generate work to speed up reward distribution. That is the most promising idea because it is the one that should really scale indefinitely with the number of users, so that's what I'll be working on from now on.

The current plan to tackle this is to switch to a model where users have a "pending balance" on the website which they can manually withdraw to their Banano wallet at any time, and which additionally will be automatically withdrawn when they reach a certain threshold, e.g. 5 BAN, and also when some time has passed since the last time they earned anything into that pending balance. This is to prevent the service from holding a lot of users' banano, which should hopefully reduce its attractiveness as a target for attacks.

Video rewards would increase that balance instead of resulting in direct banano transactions. This solves the problem of transaction spam and should also massively reduce the amount of work generation we need.

Things still left to do:

• Implement UI and API methods to request a withdrawal at any moment
• Make the balance in the frontend correctly update to zero as soon as the balance is withdrawn (either automatically or manually)
• Testing

• Make the balance in the frontend correctly update to zero as soon as the balance is withdrawn (either automatically or manually)
  • Idea: have the withdrawal handler fire an event when a withdrawal happens with the address as event argument. The rewards handler subscribes to this event, looks up the correct spectators by address, and fires a (to be created) "spectator.OnWithdrawn" event on those spectators. The ConsumeMedia goroutine should also subscribe to this event in addition to speactator.OnRewarded in order to send a checkpoint with a zero RewardBalance that will make the frontend update.
