...

• How many races should be allowed to be decided in a single block?
  • Greg's feeling is that we should go wide and not deep.  Greg only wants to go 1 deep.  Mike asks why not?
    • Going deep let's more code to interact with it, making it more 'fair'.
    • may have to persist phlo beyond a single block. - non issue.  Open question about whether phlo persists across blocks per computation.
    • Program execution goes over multiple blocks, and may take longer.
•  
  • Run to quiescence - we have an idea of what it means to run to termination.  we can have Phlo refunds.  This model is preferable.
    • Its not one validator gets to choose.  It's 1 trace, but the network agrees on the trace via consensus.
    • If you are willing to race- you shouldn't care.  
  • Going wide -gives you the opportunity to get more clients - other parties.  Non determinism is not fair.
  • It is preferable to have the races go deep.  This makes data feed harder.  Still trying to resolve this.

• Validators are accepted when a particular block hash is in their justification.  May and Must - at a further height.
  • Each region has to publish it's cost function - changed the cost function after a point
    • Accept in protocol fault tolerance associated with validator rotation.
    • In accepting a new validator - propose that the validator provide a fee to the existing validator pool.
    • Staking rev.

• Greg argues for a minimum number of validators.
  • Vlad argues that a low security shard attacks the security of the network.
  • May opt to randomly assign validators to regions.

...

• Question around paying out of transaction fees where they are delayed.  If fees exceed the validator's stake, then the validator could just walk.  (May require adding a portion of the fees to the bond, bond is held on to for 30 days, etc..)
  • Validator is in the green - Cost of the initial stake, fees as a percentage of their stake, 
  • If someone wants to take over, they have to buy out all the validator.
  • Maximize the cost of attack, maximize the amount of coin they need to purchase.
  • tradeoff - have to pay the validators out, at some rate relative to the stake they have put in.   Possible reduction of entry fees by providing a loan to reduce the cost.  Possibly just pay out the fees immediately.  Fees are already small compared to the disincentive to losing the deposit. 
  • Validators are going to bond based upon their expected return, Profitable regions will have more validators bonding.  Revenue  divided by interest rate = amount bonded.
  • Fees increase your stake - Kyle - consider the issue of cartels.
