I have a couple of basic questions and would appreciate it if someone could address them.

1) The developers have repeatedly stated that they will "Walk Away" from the project once it is released. As Zerocoin is a protocol, probably with flaws needing to be fixed or tweaked, how will the future development and management of Zerocoin be safeguarded ?

2) Without a Blockchain, how will you be able to "prove a transaction" later on (if used to buy goods from an online store etc.) ?

Thanks
