Hi All.

Find all the bit coin stuff interesting.

https://bitcointalk.org/index.php?topic=36776.0 Creating a master database of honest traders

People talking about a master database.
Given bitcoin is distributed system, shouldn't any solution also try to be distributed too. Calculated from the transaction chain? Could the chain included optional extra info to enable this?

Just my 0.02BTCs worth!
