How many total Ethereum coins will there be? I expect you don't have an exact answer but could you give us a ballpark answer at least?
Under the original model we proposed in the whitepaper for ether supply followed this function:
TS(t) = 1.5X + 0.5X*t with x being the supply created from the initial ether sale and t being time in years. This function is not bounded, but the rate of ether supply growth decreases monotonically. The goal was to divest percentagewise the initial participants in the ether sale via inflation assuming the demand would increase non-linearly thus inferring an increase in the price of ether relative to the initial sale price.
We are now investing a great deal of time in modeling the ether supply and have been considering a model that consumes ether in Txs instead of reallocation. This would eventually result in a supply equilibrium point. Once we have a bit more maturity in the mathematical models, we'll post them on github and you're welcome to review them. We'd also like to get a clear sense of ROI to demand and how our business strategy fits with increasing demand so I can list ranges of potential outcomes in the prospectus prior to the launch of the ether sale.
How r blockchain reorgs handled? Computational steps can't be rolled back nor blockchain can be re-rolled from block 0, so u r supposed to store blockchain snapshots each N-th block, which is quite expensive.
Can't a Finney attack be combined with a very long-running transactions to DoS all nodes? If a miner earns all block fees then even without a Finney attack a malicious miner could include a lot of long-running transactions into their block to slow down processing of the next block / transactions.
