ADD: Cross-chain Consids
As discussed 28 Oct w/ @cbarraford
- 24hr Withdrawal limit
To prevent Double-spend attacks on stake/withdrawal transactions, we apply a global 24hr time-limit on withdrawals on all chains.
BUT: we don't need this feature for Binance Chain, so set it to 0.
- Observer monitors 1BlockCost
The statechain is not the place to reason about 1BlockCost, so make the Observer do it:
- Poll for last block reward + fees
- 1BlockCost =
(blockSubsidy + fees) / 4
- Reorgs
Reorgs don't matter, since all the transactions will still be there
- Double Spends
Double Spends also don't matter, because the damage is done.
We need a monitoring service that alerts JP to GAS
and fix up the missing $$
