It wouldn't be the first time "rapid confirms" were part of the core tenet of a alt-coin. I do have some questions about it, though.
From the reference site: Bitshares.org - Performance and Scalability
A blockchain that processes 100,000 transactions every second generates a lot of data. The average size of a transaction on competing networks, such as Ripple and Bitcoin, is about 250 bytes. A similar transaction on BitShares averages just 100 bytes.
So, math time - if they process 100k transactions at 100 bytes each per second:
100,000 x 100 = 10,000,000 bytes per second
Which equates to approximately:
~10 MB per second, ~600 MegaBytes per minute, ~36 GigaBytes per hour, ~864 GigaBytes per day, ~6.04 TeraBytes per week, ~314.49 PetaBytes per year.
That is a pretty heavy storage requirement. I don't see how that could scale reliably if there is any kind of storage of transaction IDs and other data.
Perhaps you have an answer for this? I'm just curious about it since I haven't heard much about this alt-coin-index-thing.
