Another question -- how are you planning for people to redeem coins in 2.0? Will they simply load their existing DNotes wallets into the new client or is there some kind of transaction or swap that will take place?
It will be a 1:1 swap. DNotesVault is the recommended place to store your coins for participating in the swap without any further action, but there will be a manual process in place as well for those who don't use the DNotesVault.
How will people send their coins into the vault after PoW ends?
We will keep both networks running until the specified deadline to ensure there is plenty of time to participate. Any later comers can be handled on a case by case basis.
To elaborate a little on how the process will look.
The block reward will continue until the specified deadline, and all DNotes generated until then can be swapped. Beyond the deadline, we will create a fork with no reward, effectively creating a snapshot of the blockchain up to that point that we may maintain.
