Prior to the release, you need to put-out a version that will freeze POS rewards, to let staked-coins return from purgatory... then create a premine of equal value to the entire network... Perhaps with forced "no stake" setting.. (or protect, or whatever it is called.)
Would be better to create an auto-convert system, in the wallet itself...
The only valid SEND address would be to one master DIEM wallet, in your converter or devs hands, using a special address per wallet... Which is matched to the corresponding 2.0 wallet address, which we enter for deposit. That way, anyone who later downloads the wallet, can do the transfer themselves... That, or send you a direct notice, so you can fire-up the nodes, for the transfer to continue. (Though, you should run those for at-least a whole year. It is not like everyone sits around at the forums all day, or has them on a pool or exchange that is lively.)
Not to mention, some people might still be paying for things in DIEM, beyond the cross-over. Until they realize there is an update.
Which, should happen prior to the release of the conversion, so when they come to see why they can't sync... the get the new wallet with the converter.
Then, they also find-out about the converted wallet.
+1000 for having a smaller blockchain, due to this setup. -1000 for places that force minimum withdraws for DIEM, which will never be able to be converted. Though 0.00000001 DIEM is not worth much now... it may be in the future. Not like it costs exchanges to withdraw those small amounts. Yet they limit us to 0.0001 I believe, on most exchanges.
We talked to many devs and got a lot of input. They all said abandon ship the coin is going to DIE there were unrepairable flaws in the code that a a wallet is't going to be able to fix.
But our community came together and and we got bitsta on board to rebuild the coin. I'm hoping he can pop in here soon to give you some more of the technical side of things but he's helping us an AC rebuild at the same time.
I know a trade in isn't preferable method of doing this but my understanding is that it's the only way.
The problem with stopping the old block chain is 1 we don't have control of it. That went with the old dev and also we would have no way to verify the amounts people have. After the big tradein were going to do our best to facilitate stragglers by having them send us the old coin and we send them back new coins.
With the exception of Comkort I believe we have everyone on board that holds DIEM and we'll get in touch with them one way or another so the min withdraw shouldn't be an issue. On the plus side, if you try and send coin from an old address to a new address is should come up as invalid and not allow you to send. Which will hopefully drive that person to investigate whats up.
