What are your thoughts on digital coin?
I grabbed the "Digital Coin Technology" pdf file.

It looks to me like it fails in the second paragraph:
Quote
This
 Digital
Coin
 serial 
number
 can 
be 
up 
to 
512
 numbers 
long. 

The
 Digital
Coin
 software

 alone 
can 
find,
 read
 and
 alter 
this serial
 number.


If the DigitalCoin software can read the serial number, then so can other software.  It is simply not true that "The DigitalCoin software alone can ..."

Either you have a central server running the DigitalCoin software and you have to trust that the people running that server won't double-spend DigitalCoins.

Or... you have Bitcoin, where the "serial numbers" are the public keys of coin generation transactions.
